Introduction:
Halo: The Master Chief Collection is without a doubt, one of this year’s most ambitious titles. As a means of celebrating the ten-year anniversary of Halo 2 and brining the series to the Xbox One, 343 Industries has bundled the complete experiences of all the Master Chief games in the Halo series this holiday. Here, you will be able to tackle all four Campaigns of Halo: Combat Evolved Anniversary, Halo 2: Anniversary, Halo 3, and Halo 4, as well as relive all four Multiplayer experiences, complete with every map every shipped – DLC and PC exclusives included. The achievement list for Halo: The Master Chief Collection is grand. Covering, for the first time, 4500 gamerscore, there are four hundred and fifty achievements to be earned. The achievements are split between six distinct segments – Overall, Halo: Combat Evolved, Halo 2, Halo 2: Anniversary Multiplayer, Halo 3, and Halo 4 – and will task players with a number of feats both familiar and fresh. There are Easter Eggs to be discovered, mission-specific achievements to be tackled, collectibles to be recovered, and a number of milestone-based achievements spanning both the single-player campaign and multiplayer. At a bare minimum, given one pesky achievement, it will take three months to complete the entire game. With enough skill, persistence, and dedication, Halo: The Master Chief Collection will be one hell of a completion to show off on your tag. 

Initial Playthrough - Legendary (Reroute to "Playlist" section if new/unfamiliar to Halo games):
As a personal recommendation, go ahead and play through each of the four campaigns on the Legendary difficulty setting right from the start. You can opt to play cooperatively with friends or by yourself as it doesn’t matter too much. During these four initial playthroughs, you will naturally unlock forty achievements for completing each individual mission in the four campaigns as well as another sixteen achievements for completing each individual campaign on the legendary difficulty setting. If on these playthroughs you undertook cooperative action, you will also unlock three achievements after finishing your very first mission on legendary with a Co-Op partner. When playing through the campaigns, make sure to familiarize yourself with enemy AI behavior and the level design for each mission. These two facets will be extremely important in later playthroughs.

During these initial runs, take the time to thoroughly explore each and every mission. Exploration will be necessary in hunting down three sets of collectibles: terminals in all four campaigns, skulls in the first three campaigns, and toys in the Halo 2 campaign. In total, there are thirty-eight terminals to activate, which will net you forty-three achievements; there are forty-one skulls to recover, which unlock another forty-six achievements; and lastly, there are eight new toys to hunt down, which will unlock nine achievements. Please keep in mind that in regards to the skull collectibles, Halo 2's skulls, unlike Halo: CE and Halo 3, must be collected on legendary with the exception of Blind and Assassins. 

The initial playthrough craze does not end there. Use this time wisely to knock out the many mission-specific achievements that are tied to the Legendary difficulty. There are quite a few mission-specific achievements to take into account: fourteen in Halo: Combat Evolved, seven in Halo 2, five in Halo 3, and seven in Halo 4. As a means of minimizing the amount of playthroughs necessary for completion, let’s take into consideration the Easter Egg achievements at this time. In Halo: Combat Evolved, there are seven that must be discovered. In Halo 2, there are ten eggs. In Halo 3, there are another ten worth hunting down. Lastly, in Halo 4, there’s only one single egg worth discovering. 

It’s almost time wrap up the initial playthroughs section of this walkthrough, but before we can do that, let’s shift focus to some of the overall achievements that span all four titles. Between slaughtering all nine enemy types across the four campaigns, unlocking campaign medals, and completing campaign missions, you will naturally gain progress towards forty-four of the overall achievements within the game. Chances are you will only make a small dent in these achievements, but the next few playthroughs are sure to see said tasks complete in no time.

UPDATE: 
The activation and utilization of negative scoring skulls such as BANDANA and SCARAB will no longer void any achievements related to mission completion and campaign completion. Unfortunately, these skulls will still void Par Time and Par Score achievements. 

NOTE OF IMPORTANCE: 
At any time during these initial playthroughs within the Halo: Combat Evolved and Halo 2 campaign, make sure to swap between classic mode and remastered mode at least once per mission. This is necessary for Halo: Combat Evolved's "Before and After" achievement and Halo 2’s "Tighten Up The Graphics" achievement.

LASO Playthrough (Preferably Co-Op):
This is where the campaigns of all four Halo games become a horrendously intimidating nightmarish hell, while ironically remaining one of the most satisfying experiences in all of gaming. For those unfamiliar with the term “LASO,” it’s a cleverly designed acronym for what was once considered a fan-made difficulty setting in the Halo games. Originally called, “Mythic” this difficulty setting has become a legitimate staple within the Halo series, tasking players to complete the entirety of a campaign on legendary, with every skull modifier turned on at once; in other words, Legendary All Skulls On. 

In Halo: The Master Collection, players will be rewarded with four individual achievements that pertain to successfully completing each of the four Campaign’s new LASO playlists, while a fifth achievement will unlock once all four LASO playlists have been completed. Get ready to grab your closest friends and probably stalk and beg the best Halo players on the web. You’re going to need a skilled and persistent team to get these five achievements done. With certain skulls permanently cloaking enemies, and others that remove your HUD and recreate enemy behavior to mirror that of omniscient creatures that know your every move and hiding spot, these four playthroughs will test even the mightiest of seasoned Halo veterans.

NOTE OF IMPORTANCE: 
Each of the Campaign's LASO playlist achievements can now be exploited by sharing checkpoints. If one player gets to the final mission of a Campaign, they can "Save/Quit," invite another player to the lobby, and "Resume" the playlist. When the final mission loads, the host should now "Save/Quit" again. This will give any players in the lobby that final mission's starting checkpoint for whichever Campaign's LASO playlist this was done for. 

Cross-Game & Game Specific Playlist Playthroughs:
Halo: The Master Chief Collection marks the debut of Campaign playlists. These playlists aim to string together a series of campaign missions that share a common thread. There are specific campaign playlists for each individual game, as well as cross-campaign playlists. At this time, there are a total of eleven achievements related to these playlists. While hopping back into the campaigns so many times may seem daunting and even downright boring, it’s a task that requires your full attention and dedication to the single-player. 

These achievements are actually quite enjoyable. They speak to the confidence of the developer in creating such unique playlists that revolve around a central element, such as packaging all the Flood missions across the first three campaigns or packaging all the vehicular missions of Halo 2. Again, these achievements are tedious, but other than the Master Chief Saga playlist (which is considered the third full playthrough [automatically set to Normal] of all 45 campaign missions), they shouldn’t be too bad nor take too long. On the bright side, these playlists will help add progress for the overall kill, mission completion, and medal obtainment achievements!

Par Time & Par Score Playthroughs:
These are the last two full playthroughs of each campaign you’ll have to endure. In total, there are forty-four Par Time achievements - eleven in Halo: Combat Evolved, fourteen in Halo 2, ten in Halo 3, and nine in Halo 4 – and forty-four Par Score achievements - eleven in Halo: Combat Evolved, forteen in Halo 2, ten in Halo 3, and nine in Halo 4

These tasks require players to complete each mission of every campaign in two ways. For par time, you’ll have to complete the mission under a specific allotted time (in other words, speed-running). As for par score, you’ll need to achieve the base competitive score for each mission. If you have played Halo 3 in the past, the par score achievements are similar to the meta game scoring achievements seen there. Points will be rewarded based off medals obtained in combat; such as killing sprees, melee attacks, headshots, and multikills. 

All in all, some of these achievements may actually come naturally during any of the previous playthroughs, though for the sake of breaking down the achievement list, par time and par score achievements are best explained as if they are to be done in their own separate playthroughs. This is because of the following reasons:

  1. Your initial playthrough is already covering a vast majority of the achievement list, meaning you can’t beat the Par Time for every mission while collectible hunting and grabbing other mission-specific achievements;
  2. Given the difficulty of your LASO playthroughs, there is no possible way to achieve Par Time on each mission, let alone Par Score if you’re skipping firefights;
  3. Many of the playlists do not cover every single mission in a Campaign, so it’s impossible to fully pair these achievements with the playlists playthrough;
  4. A dedicated playthrough here for each Campaign adds even more progress for those pesky overall kill, mission completion, and medal obtainment achievements. 

As stated before, you don’t necessarily have to follow this suggestion, however it’s what is best for completion purposes. As a final note, there are four different achievements that are rewarded for completing each of the four campaigns on the Legendary difficulty setting in under three hours. By utilizing the speed running tactics in the videos provided in the guide below, you will almost certainly grab the par time achievements for each of the missions on the way. As for par scores, these can be approached in a solo or co-op playthrough and you can visit THIS LINK, courtesy of Life Expectancy, for detailed information regarding how the par scores are best obtained in each mission of the four campaigns. 

Miscellaneous Tasks:
At this time, it would appear that a few miscellaneous achievements remain. Get ready to mark your calendars; playing a game of Halo: Combat Evolved on the 15th of any month, a game of Halo 2 on 9th of any month, a game of Halo 3 on the 25th of any month, and a game of Halo 4 on the 6th of any month, will unlock four distinct achievements. Other than that, there are a few achievements between Halo: Combat Evolved and Halo 2 that are not directly tied to a specific mission. For example, in Halo: Combat Evolved, there are achievements for killing a Hunter with a single pistol round, completing a level without jumping, and completing a level on Legendary without taking health damage. As for Halo 2, you’ll need to keep in mind that there are achievements for completing a level in co-op on Heroic with the Masterblaster Skull active, completing a level on Heroic with only the Streaking Skull active, killing seven enemies from behind in a row without being spotted, completing any campaign level without dying on Normal, and killing a berserk brute with a melee attack. As a standard set of miscellaneous achievements, these can be achieved on any mission, so long as the pre-requisites are in place. 

Multiplayer for Main Game:
The multiplayer portion in Halo: The Master Chief Collection will consume a good amount of your time. Primarily, a small chunk of the online achievements are milestone-based. For instance, you’ll need to win five hundred online matches (custom games work as an alternative) for a total of eleven achievements. Likewise, although the next two tasks are split between campaign and multiplayer, you’ll also be asked to complete five hundred missions or online matches (custom games work as an alternative) and obtain a grand total of ten thousand unique campaign or multiplayer playlist medals. The former task covers twelve achievements and the latter covers eleven different achievements. In addition to these two tasks, you will also be required to kill at least twenty thousand enemies or players between campaign and multiplayer. Again, this covers three separate achievements. Lastly, one of the most burdensome achievements on the list requires players to boot up a custom Game of capture the flag on Halo: Combat Evolved’s Blood Gulch. The catch is that you’ll need to do this with four players on the same console. As you can see, many of the aforementioned achievements will unlock through minimal effort as you spend time battling online opponents through the online matchmaking. 

On the other hand, there several achievements related to custom games, forge mode, and the Halo 2: Anniversary Multiplayer playlist. For example, there are two achievements related to creating five custom game types and crafting five maps in forge mode, while another achievement is rewarded for killing a 343 Industries developer (or a player who has). In addition to this, there are five multiplayer Easter Egg achievements related to particular Halo 2 (Classic) maps, thirty-five competitive multiplayer achievements related to Halo 2: Anniversary playlists, and three multiplayer Easter Egg achievements related to Halo 3 maps. As mentioned, some of these achievements are as simple as finding a hidden Easter Egg in a multiplayer map, though a decent amount of them are rewarded for performing luck-based and skill-based feats while playing on specific maps and in specific playlists. Fortunately for us, nearly all of the multiplayer achievements can be obtained with secondary controllers or even by ourselves in custom games, except for the following seven below. 

NOTE OF IMPORTANCE: 
All of the multiplayer Easter Eggs and Halo 2: Anniversary multiplayer achievements can be unlocked in custom games alone or with other players so long as the achievement description does not say, “in a matchmade game.” Thus, "Shields Up!," "MVP," "Warden," "Ninja Redux," and "Flaming Ninja Anniversary" are five achievements that must be done in matchmaking. Additionally, despite its description not stating so, "Zealot" must be done in matchmade games as well. Finally, "Bite the Hand" will require an online connection so that you can play against another player, but this can be done in custom games. 

Mop-Up for Main Game:
At this point, you’ve exhausted the four campaigns to the point of never having any intention to return to their narratives. You have probably even dedicated more than one hundred hours to the multiplayer as well. If you have somehow missed any of the four hundred and fifty achievements on this list – chances are you did – simply use this time to mop them up. It should be noted that if your full Legendary playthroughs of the Halo 4 campaign were always done cooperatively, you unfortunately have to revisit that campaign yet again. Halo 4 is the only game that requires players to complete the campaign on solo Legendary, so keep that in mind. Other than that sad piece of news dropped here, you should be good to go in terms of mopping up what’s left, especially on the multiplayer portion of this collection.

LifeExpectancy's Boosting Guide

Introduction to Spartan Ops:
Welcome back, Spartans. In Halo: The Master Chief Collection’s latest Title Update, 343 Industries has showered us with fifty new achievements for a total of five-hundred achievements. This new list covers the basics of the newly implemented Spartan Ops Mode for Halo 4, as well as introducing some multiplayer milestone achievements and smaller miscellaneous tasks. Most of the new achievements can actually be obtained offline and solo, though nine of the multiplayer achievements will require an online connection for matchmaking. Additionally, all twelve of the multiplayer achievements are retroactive, so any progress you already had for them will be tracked (some players are not receiving their retroactive tracking correctly). Get ready to score several thousand headshots, amass a variety of grindy multiplayer medals, and complete Spartan Ops on the Legendary difficulty. Since this list covers such tedious multiplayer tasks, it may take more than one hundred hours of gameplay to nab all fifty achievements. 

Spartan Ops:
Halo 4’s Spartan Ops mode makes a return in Halo: The Master Chief Collection and brings with it a total of twenty-one achievements. For those who have played through the original Halo 4, these achievements will be very familiar. For the newcomers, it’s best to mention that Spartan Ops is a cooperatively driven mission-based mode that allows parties of up to four players to partake in Crimson Team’s adventures as the Spartan IV’s deal with Covenant and Promethean threats after the events of the Halo 4 campaign. There are a total of ten episodes in Spartan Ops, each of which contain five chapters. 

Your first Spartan Ops achievement will be earned for completing any of the chapters, while another eleven achievements are earned for completing all ten episodes. Additionally, there are four difficulty-related completion achievements for completing the entirety of Spartan Ops on Normal, Heroic, Legendary, and solo Legendary. There are also three chapter-specific achievements in Spartans Ops that are best done with cooperative partners. Lastly, there are two miscellaneous achievements to be obtained in Spartan Ops, one of which requires players to perform an assassination on a Promethean Knight and another that invites players to find one of the many hidden RvB Easter Eggs in any chapter. 

Multiplayer:
343 Industries has dropped another round of multiplayer achievements this time around. Unfortunately, only three of these twelve achievements can be boosted in custom games (or even obtained through Spartan Ops). These three achievements are for achieving 2,500 headshots, obtaining 2,500 assists, and receiving 250 beat down medals (not to be confused with melee attack medals; beat downs must be from behind). 

As for the other nine achievements, they must all be obtained in matchmaking, which automatically proves to be a near impossible feat given the rough state of the multiplayer, the harsh restrictions on the achievements, and the nature of such milestone-based achievements. On the note of harsh restrictions, there are two achievements that can only be obtained on Halo 2 Anniversary maps. One of these achievements asks players to obtain 100 Splatter medals and the other achievement asks players to obtain 100 Environmentalist medals. The former is best obtained through the Halo 2 Anniversary on Stonetown or Big Team Battle’s playlist on Bloodline, while the latter can really only be obtained on Lockdown. Lockdown appears most frequently in the standard H2A playlist, the Halo Championship Series playlist, and the Team SWAT playlist. 

Two of the remaining seven achievements ask players to dip their toes in objective matches and receive a grand total of 250 King of the Hill medals and 250 Capture the Flag medals. There’s also two achievements that reward excellent skill, one of which asks players to obtain 100 Killing Spree medals and another that requires players to obtain 100 Legendary medals. As for the last three achievements, they can be obtained for earning a total of 250 Double Kill medals, 250 Killjoy medals, and 500 Grenade Kills or Plasma Kill medals. 

Clearly, these nine matchmaking-only achievements will require players to invest countless hours, maybe hundreds, in the multiplayer portion of the game. Given the rough state of the multiplayer, it’ll take a considerably long time to earn all of these achievements, and unfortunately, there are very few boosting methods that exist in order to speed up the process. With enough skill, dedication, and time, any devoted Halo player can nab all these achievements in a matter of weeks.

UPDATE: 
Thanks to LifeExpectancy, there is a user-friendly boosting guide (FOUND HERE) that explains to players the different methods involved in obtaining all of the matchmaking-only achievements with two parties of four to five players. Though this general boosting method may prove to be a difficult set-up (and will take longer unless performed with two players who have four controllers each), it will help those looking to find decent workarounds for the milestone-based achievements. 

Miscellaneous for Spartan Ops:
This title update also brings with it a host of miscellaneous achievements that aren’t necessarily tied to Halo 4’s Spartan Ops or the matchmaking portion of multiplayer. In fact, you’ll come to notice that there is an achievement that requires players to complete a campaign mission with all of that particulars campaign’s LASO playlist skulls enabled. Additionally, there’s an achievement tied to custom games in Halo: Combat Evolved for launching a Warthog in the air for five seconds and then having it splatter an enemy. Lastly, Halo 3’s Mythic multiplayer map skulls have returned which offer a total of seven achievements. These skulls are tied to the following maps: Assembly, Citadel, Heretic, Longshore, Sandbox, and Orbital.

Beyond all that, there are a total of eight achievements that can be quickly boosted on your own in custom games. Four of these achievements ask players to complete a match on at least eight different multiplayer maps for Halo: Combat Evolved, Halo 2 Classic, Halo 3, and Halo 4. The other four achievements here task players with completing a match on at least four different game types in Halo: Combat Evolved, Halo 2 Classic, Halo 3, and Halo 4. Let it not be mistaken that it’s eight different maps per game and four different game types per game. 

Conclusion for Spartan Ops:
Overall, the latest title update for Halo: The Master Chief Collection brings a total fifty new achievements to the game, a small amount of which will require players to spend hundreds of hours on the Multiplayer portion of the game. Between the twenty-one Spartan Ops achievements, the thirteen multiplayer achievements, and the eleven miscellaneous achievements there’s enough incentive for players to hop around the different aspects of the game and mop up whatever achievements they desire to grab. If you’re looking to grab all fifty however, be prepared to invest most of your gaming time to Halo’s broken Multiplayer.

Halo 3: ODST DLC & ODST Title Update DLC
(Full Roadmap found HERE)

Introduction
Welcome back, Spartans! In late May of 2015, 343 Industries added a brand new expansion to the already massive Halo: The Master Chief Collection. For those who played the Collection between launch date and the 19th of December (2014), Halo 3: ODST is a free expansion that adds ninety-nine new achievements to the frey. There's also an additional achievement under a smaller Title Update for the newly remastered Remnant Multiplayer map, thus making it one hundred new achievements for a total of one thousand gamerscore. This new list covers the basics of the newly implemented ODST Campaign, from mission and game completion, to par scores, par times and even a variety of miscellaneous tasks. Additionally, the single Remnant achievement is a task familiar to fans of the collection, as players will have to find another BLAST soda can hidden in the map. Prepare to drop with this enjoyable expansion and get ready to experience the ODST Campaign all over again on Xbox One.

Halo 3: ODST Playthrough
To begin, go ahead and start the Halo 3: ODST Campaign on Legendary from the get-go. It's suggested to run this playthrough with one or two Co-Op partners, but playing on your own is perfectly fine as well. During this playthrough, you will naturally unlock fourteen story-related achievements, as well as four achievements for stacking the Campaign completion on the highest difficulty setting. On top of this, it's worth taking the time in between missions to track down the hidden collectibles in the New Mombasa Streets. There are thirty collectibles here (29 in the Streets, which then unlock 1 in Data Hive, the game's seventh mission), all of which have their own achievement and then an overall achievement for finding all thirty. This playthrough may net a couple of other achievements, such as par times, par scores, and miscellaneous feats, though focus on collectibles and Campaign completion for the time being. 

Halo 3: ODST Playlists
Much like the previous games, Halo 3: ODST features Campaign playlists. As one could imagine, there's an achievement for completing a single playlist, as well as completing three playlists and a LASO playlist. For the purposes of these achievements, it's best to complete the Legendary playlist as your first playthrough, the LASO playlist as your second playthrough, and then choose a short playlist for the final selection. When tackling the LASO playlist, please refer to the guide below for brief notes concerning key details on each of the Campaign's eight missions. Remember, it's always better to tackle such a playlist with a group of dedicated players rather than trying to do it on your own. 

Par Scores, Par Times, & Legendary Speed Run
Although it would be overwhelming to complete a second, dedicated Legendary playthrough for speed running purposes, it has been found by many community members that even a casual approach to the Campaign on Legendary (your first playthrough) can easily net the achievement that requires players to complete all eight missions - not counting the New Mombasa Street segments - on the highest difficulty in under three hours. To reiterate, this will most likely come naturally to most players without much planning, attention, or knowledge of the missions. As for the par scores, most of these will most likely come naturally during your initial Legendary playthrough, with the exception of (possibly), Uplift Reserve and Coastal Highway. If this happens, you'll need to tweak the difficulty and skulls for individualized mission runs. For par times, these might be a little difficult to stack on Legendary. As such, lowering the settings down to Easy for individualized mission playthroughs is your best bet for achieving the par time achievements. 

Miscellaneous
Much like the previous games in the collection, Halo 3: ODST's achievement list also brings with it a number of miscellaneous achievements ranging from hidden Easter Eggs to mission-specific achievements, some of which are tied to the Heroic or Legendary difficulties. Most of these might not necessarily come naturally to players during their previous playthroughs, though loading up missions via the Campaign lobby at any time will work fine when hunting down what's left. For example, there's an achievement for completing a mission on Solo Legendary without firing your weapon or throwing a grenade, and achievements for killing five sleeping Grunts on the New Mombasa Streets, piloting a Banshee on Kizingo Boulevard, completing a mission without picking up a Covenant weapon, and even finding another hidden music cue and caveman Easter Egg. As for the smaller content update brought with this expansion that adds the Halo 2: Anniversary Remnant map to Multiplayer, there's a hidden BLAST soda can that must be found and destroyed. All in all, there's about two dozen miscellaneous achievements to nab, though none of them are particular difficult or time consuming. 

Conclusion for Halo 3: ODST & ODST Title Update
Overall, as an expansive add-on the for Halo: The Master Chief Collection, the Remnent Multiplayer map and Halo 3: ODST Campaign add hours of joy to an already pleasant experience. With one hundred new achievements to grab, most of which will come naturally over one Legendary playthrough and one LASO playthrough, players can expect to sink about twenty-five or more hours into this add-on. If you're looking for the full completion, then as always, be prepared to tackle a tough task: Completing Halo 3: ODST on LASO.

Halo: Reach Title Update DLC

Introduction
We return once more, Spartans! Developer 343 Industries has finally added Halo: Reach to Halo: The Master Chief Collection. For those who are subscribed to Game Pass, the entirety of the game will be available to download for free; otherwise, the Multiplayer portion of the game is free to all and the Campaign will cost about $10 to purchase. With this expansion, there are one hundred achievements to be earned. Similar to the collection's previous lists, these achievements range from Campaign completion and hidden Easter Eggs to a variety of miscellaneous tasks and two online-only feats. You will likely spend more than 40-50 hours with Halo: Reach to see everything complete, so strap in and enjoy this final adventure.

Playthrough #1 (Legendary Playlist)
To begin, go ahead and start the Halo: Reach Legendary Campaign playlist. If you'd like to save an extra playthrough later on and stack "A Monument To All Your Sins" here, which tasks you with completing the game on solo Legendary, then make sure to play alone on this first playthrough. If you don't mind playing through the Campaign an extra time, then feel free to tackle this cooperatively. During this initial playthrough, you will naturally unlock nine story-related achievements for each mission, as well as four (or five if playing solo) achievements for stacking the Campaign completion on the highest difficulty setting.

It's worth taking the time during each of the nine missions to track down the hidden Data Pads. There are two of these collectibles on each main mission of the game; however, Lone Wolf, the post-game firefight mission, only has one. Thus, there are nineteen collectibles overall, all of which have their own achievement and then an overall achievement for finding all nineteen. Lastly, your time spent on each mission of this playthrough will likely be slow-paced, so ignore the par time and par scores entirely. Instead, focus on grabbing the various Easter Egg achievements and mission-specific achievements.

Playthrough #2 (LASO Playlist) + Additional Playlist
There are three separate achievements related to the Halo: Reach Campaign playlists. Fortunately, your first Legendary playthrough will net "Reach Has Been Good to Me" for completing a single playlist. The other two achievements are "Who Needs Red Flag?" and "Why Do This To Yourself?," which are earned for completing three playlists total and completing the Halo: Reach LASO Campaign playlist, respectively. When tackling the LASO playlist, please refer to the guide below for a video guide playlist on each of the Campaign's nine missions. Remember, it's always better to tackle such a playlist with a group of dedicated players rather than trying to do it on your own.

Par Scores, Par Times, & Legendary Speed Run
On your first playthrough of the Campaign, regardless of whether it was solo vs cooperative, you would have likely taken a decent amount of time on each mission to hunt down collectibles and Easter Eggs. Thus, you will likely have to replay each mission on Legendary in order to net good completion times toward the "Keep Your Foot on the Pedrogas" achievement, which tasks you with beating the Campaign on Legendary in under three hours. As you go back to missions to speedrun them, you should naturally earn all of the par time achievements, too. After unlocking your three-hour achievement, all you need to do at this point is mop up any par time and par score achievements on a lower difficulty via mission select.

Miscellaneous + Online
A number of the miscellaneous achievements in this game will be earned during one of your several playthroughs; however, for those that remain, you can use mission select to choose specific missions and hunt down what you may have missed. There are also a number of achievements that, while at first glance appear to only be obtainable online, can actually be done in Firefight or Custom Games on your own, such as killing 1,000 Skirmishers, killing ten enemies while jetpacking, splattering an enemy with a forklift, and assassinating ten enemy players. Lastly, make sure to play any mission or Multiplayer game of Halo: Reach on the 14th of any month in order to unlock "Remember Reach."

It's worth calling out that there are two online achievements: "Negative, Ghostrider" and "Skunked." The former will require you to earn a Skullamanjaro in a matchmade Headhunter game, while the latter tasks you with winning a matchmade game of Invasion in the first phase.

Conclusion for Halo: Reach
This is it, Spartans: the final adventure of The Master Chief Collection. If you've made it thus far, the achievement list for Halo: Reach should pose no burden; it follows the same structure as those that came before it, boasting several enjoyable (yet rightfully challenging) feats for the most dedicated of Halo players.

Overall Conclusion:
Overall, Halo: The Master Chief Collection offers an unmatched experience this year. With four complete games bundled for the price of one, players will be able to hop back and forth between their favorite experiences in both the campaign and multiplayer with ease. The achievement list here is nothing short of difficult; you’re going to have to sit down and dedicate a tremendous amount of time for each of the four games. Many of the overall achievements will come naturally as you play and you will already have noticed that many of the Halo: Combat Evolved and Halo 4 achievements are similar to their original counterparts. With the exception of the new toy and terminal collectibles in Halo 2, par time and par score tasks for each game, and a few other new achievements, fans of the series should feel comfortable with the list and have no problem unlocking a vast majority of the achievements. With steadfast dedication and skill, Halo: The Master Chief Collection can be completed in as little as three months and a few hundred hours of playtime. It’ll take a number of playthroughs and multiplayer matches to do so, but the end result will be grand. With that, good luck, gamers. Have fun with this fantastic bundle and we’ll meet again this time next year for Halo 5: Guardians.

Complete the Master Chief Saga playlist.    (73) 

As a means of experiencing Master Chief's epic journey from The Pillar of Autumn in Halo: Combat Evolved and all the way to the tragic events of Midnight in Halo 4, the Master Chief Saga playlist compiles all forty-five Campaign missions on the Normal difficulty. As such, this means the aforementioned playlist will net an entire playthrough of each Campaign, allowing you time to grab any collectibles, Easter Eggs, and even non-difficulty-tied mission-specific achievements that you have not already obtained in prior playthroughs.

Like any playlist, this does not need be completed in one sitting. Rather, the game will save your progress in the standard fashion after each checkpoint or completed mission, meaning you can return to this playlist in the Main Menu at any time. Also, because the difficulty is automatically set to Normal, there shouldn't be any issues in completing this playlist with ease, be it on your own or with a cooperative partner. Once the entire playlist has been completed, from beginning to end, the achievement will finally unlock.

Thanks A Killion 20
Kill 20,000 enemies or players.    (9) 

As a cumulative achievement, this will most likely come naturally during your time playing the four campaigns and messing around in the multiplayer or in custom games. On average, each mission in every campaign usually houses anywhere from 150 to 200 enemies in total. Using this estimate, a single playthrough of all four campaigns will net a low total of 5,000 kills to a high total of 8,000 kills towards this achievement. 

You will be playing the four campaigns a bare minimum of around five times each for a multitude of different achievements. This means obtaining 20,000 enemy kills will be as simple as working on every other campaign-related achievement whether that’s in a solo playhrough or cooperative playthrough. On the other hand, multiplayer and custom game kills against online opponents also count towards this achievement, so splitting your time between the single Player and the multiplayer will help unlock this achievement with greater ease. Once you have amassed a total kill count of 20,000 enemies or players, this achievement will finally unlock.

Medal Completionist 20
Collect 10,000 campaign or playlist medals.    (3) 

Medals are preset rewards that appear in the Campaign and Multiplayer portions of the game. These medals showcase special in-game tasks that players have undertaken in the form of achieving different kill sprees, completing specific objectives, and performing other combat-oriented tasks.

As a general note, there are well over one hundred unique medals that can be obtained during your career lifetime on both Campaign and Multiplayer. Below, you will find ten of the most common medals with their appropriate descriptions:

  • Headshot – Kill an enemy with a headshot (Campaign or Multiplayer)
  • Grenade Stick - Kill an enemy with a Plasma grenade stick
  • Supercombine - Kill an opponent by using a Needler
  • Double Kill - Kill two opponents within four seconds of each other
  • Multi-Kill – Score three or more kills within 1.5 seconds
  • Beatdown – Kill an enemy/opponent with a melee attack
  • Close Call - Kill an opponent while your health is low and survive
  • Killjoy – Kill an online opponent who is on a Killing Spree or higher
  • Killing Spree – Kill five enemies/opponents in a row without dying
  • EMP – Kill an enemy within 2 seconds of destroying their shields with a charged Plasma Pistol shot (Campaign Only)

As you can see, there are many unique medals that can be obtained in both the Campaign and Multiplayer. On average, players who are tackling the Campaign on their own (or even with a Co-Op partner) can net anywhere from fifty to one hundred medals in a single mission. In Multiplayer, an experienced player can net an average of ten to fifteen medals so long as they vary their playstyle and know how to handle different encounters with online opponents.

This achievement may seem like a daunting task and even a tedious grind, but with so many Campaign playthroughs required, you will find that these medal achievements come naturally without much thought while tackling the four different Campaigns. Once you have obtained a total of 10,000 medals, this achievement will finally unlock.

The Guardians Are Coming 5
Get killed by the Guardians.    (17) 

The Guardians are an unknown entity within the Halo games that appear to be the cause of death when players are killed under unknown or bizarre circumstances, or even when players travel outside the boundaries of a Multiplayer map during an online game.

In addition, objects that hold no ownership to a player, such as the train in Halo 2’s Terminal Multiplayer map are grounds for Guardian induced deaths. With this information on hand, the easiest way to obtain this achievement is to load up a Custom Game on Halo 2's Terminal map and simply allow the train to run you over. In doing this, the achievement will unlock without any issues.

Mystery Achievement 5
Inscrutable. Mysterious.    (27) 

Similar to the "fortune cookie" Easter Eggs in Halo: Combat Evolved and Halo 3, this achievement is obtainable at any point in the game while editing any map in Forge Mode. When you are ready to save your custom map, enter ".fortune" as the map name and the following message will appear: "Sorry, this fortune is temporarily out of order." As soon as this message appears, the achievement will unlock right away.

Sample Plate 20
Complete three cross-game playlists.    (4) 

In Halo: The Master Chief Collection, cross-game playlists make their debut as a means of experiencing a particular set missions between all four Campaigns that all share a common thread. Hand-crafted by the developer, some of these playlists are unique, such as all the Banshee-related missions or all Flood-related missions or even all the sniping-related missions that are spread out among the four Campaigns.

Since the Master Chief Saga playlist must be completed for a separate achievement, all that is required is to complete a minimum of two other cross-game playlists for this achievement. The best playlists to experience for this achievement are the following three, though you don't need to follow this recommendation:

  • Hogs, Jets, Tanks, and Mechs - Assault on the Control Room, The Arbiter, The Storm, Infinity
  • Final Four - The Maw, The Great Journey, Halo, Midnight
  • Get in the Ring - Halo, Delta Halo, Halo

Simply pick and choose whichever three cross-game Campaign playlists you'd like to work on and once they have all been successfully completed, this achievement will be yours.

I Dabble in Slaying 10
Complete one cross-game playlist.    

Please refer just above to "Sample Plate" for more information.

Stick With It 5
Play a multiplayer or co-op game at least 3 months after your first game.    (18) 

This achievement is the sole reason why Halo: The Master Chief Collection will take a bare minimum of three months to complete. As the description states, all that is required of you is to enter a Multiplayer match or start a Campaign mission three months after the very first day you played the game.

Generally, players will be playing the Campaign missions and tackling the Multiplayer on release date, November 11th, so this achievement has the potential to unlock as early as February 11th for launch-day players. If this is not the case for you, just stick with the game long enough and this achievement will naturally unlock in no time.

Veteran 30
Complete all campaigns on Normal difficulty.      (2) 

Please refer below to "Legend" for more information.

War Hero 40
Complete all campaigns on Heroic difficulty.      (2) 

Please refer below to "Legend" for more information.

Legend 50
Complete all campaigns on Legendary difficulty.      (63) 

This achievement will unlock once all four Campaigns have been successfully completed on either a Solo Legendary playthrough or Cooperative Legendary playthrough. There are multiple methods in tackling the missions of each Campaign, but keep these general tips in mind when playing:

  • Utilize the Noob-Combo (Plasma Pistol/Battle Rifle) at all times when facing Elites and Promethean Knights; an overcharged Plasma Pistol shot will drain their shields, and a quick burst or two from the Battle Rifle will down these foes easily
  • Utilize vehicles – Ghosts, Banshees, Warthogs, etc. – as frequently as possible; their firepower helps clear out areas quickly and you can even drive past enemy encounters if the mission allows for it
  • When facing Hunters, get close enough so that they charge at you, allowing time to side step their attack; when the orange flesh on their back is exposed, shoot it, as this is their only weak spot
  • Don’t neglect the basics of using cover; when your shields drop down, hide behind a wall or crouch behind an object before charging back out into battle
  • Try exploring the levels and finding alternate routes behind or around the enemies; this can help save time by skipping major firefights, especially in Halo: CE and Halo 2.

Overall, because seasoned Halo players will be familiar with both level design and enemy behavior, completing each of the Campaigns on Legendary will be quite easy. Utilizing the Noob-Combo (Plasma Pistol/Battle Rifle) is by far the best tactic when dealing with shielded enemies; so don’t neglect these weapons just because a shotgun, sniper rifle, or sword is nearby. It doesn’t matter which order you complete the Campaigns or even if you decided to hop from one Campaign mission to another Campaign mission. Once all the missions in Halo: Combat Evolved, Halo 2, Halo 3, and Halo 4 have been completed on the Legendary difficulty setting, this achievement will be yours.

Lore Master 30
Activate all terminals.     (5) 

In total, there are 38 terminals spread across the four Campaigns that must be activated for this achievement. More specifically, there are 10 terminals in Halo: Combat Evolved, 13 terminals in Halo 2, 7 terminals in Halo 3, and 7 terminals in Halo 4. These terminal stations are well-hidden within the missions of each Campaign, so it will take a keen eye and some exploration in order to track them down. The terminals also differ in appearance from game to game, which might cause confusion. In Halo: Combat Evolved, they appear to be bright yellow holograms with a flashing panel. On the other hand, terminals in Halo 4 are small, grey console stations that have a dim yellow light glowing on the face of the console.

Take note that you do not necessarily need to read/listen/watch the entire terminal because progress towards this achievement registers as soon as it’s activated. It is highly recommended to spend the two to three minutes in observing each terminal though. Once activated, they will provided crucial backstory to the Halo Universe. For example, the terminals in Halo: Combat Evolved reveal the origins of 343 Guilty Spark and Installation 04, while the terminals in Halo 4 give a glimpse into the Forerunner’s culture. Also, take note that in Halo: Combat Evolved and Halo 2, terminals will not appear while playing in Classic Mode. Once all 37 terminals have been activated, this achievement will unlock.

Delicious Brains 5
Kill 100 Flood.    (1) 

Please refer below to "Zombie Repeller" for more information.

Zombie Repeller 10
Kill 1000 Flood.    (2) 

The Flood is a unique species of highly virulent parasitic organisms that reproduce by consuming sentient life forms that hold enough biomass and cognitive capability to sustain life. Argued to be the very sole reason why the entire events of the Halo Universe exist, the Flood are by far the greatest threat in the existence of life.

These enemies are extremely adaptable, dangerous, and expendable. Rarely will you ever encounter a firefight with the Flood in which victory will be smoothly achieved. There are a few different variants, ranging from the Infection form to the Carrier and Combat forms as well. The latter of the three – the Combat form – are the most vicious in battle.

Armed with nearly every type of weapon imaginable, you will be hard pressed to hold your own without arming yourself with significant firepower. Generally, the Shotgun and Energy Sword are the best weapons to use against the Flood. It is also important to take note of one peculiar note: When you kill a Combat form, they aren’t truly dead yet, because the Infection form can essentially “revive” them. With this said, make sure to shoot off – or slice off – their arms and heads and feet when they topple over to their assumed death.

Lastly, take note that the Flood does not appear until mid-game in Halo: Combat Evolved, Halo 2, and Halo 3. Specifically, they are present - in heavy force - in all Halo: CE missions after "343 Guilty Spark." In Halo 2, they are present in "The Oracle," "Sacred Icon," "Quarantine Zone," and "High Charity." Lastly, in Halo 3, they will appear in "Floodgate," "The Covenant," "Cortana," and "Halo." Furthermore, the Flood do not appear in Halo 4 at any time. Once you have killed a total of 1,000 Flood enemies, this achievement will unlock.

Bro Hammer 10
Complete any co-op level on Legendary difficulty.      (14) 

This achievement will unlock so long as you successfully complete any mission within any of the four Campaigns while playing cooperatively on Legendary. Chances are you will be playing most of the missions with a friend or other groups of people for some of the harder missions and LASO playlists, so this achievement will come naturally.

Throne of Bones 30
Find and claim all the campaign skulls in Halo:CE, Halo 2, and Halo 3.    (12) 

In total, there are 41 skulls scattered across the aforementioned Campaigns that must be collected for this achievement. More specifically, there are 13 skulls in Halo: Combat Evolved, 15 skulls in Halo 2, and 13 terminals in Halo 3. These skull collectibles are extremely well-hidden and come in the appearance of an actual human skull. At times, you will find that some are only obtainable for reaching obscure locations via grenade jumps and other advanced tactics. Needless to say, it will take a tremendous amount of exploration to locate these skulls.

These skulls are a unique collectible in that they act as significant gameplay modifiers. When activated via the Campaign Lobby Menu, skulls will alter the way the Campaign is played by either removing your HUD, permanently cloaking all enemies, promoting enemies to their highest rank, or even disabling the recharge ability of your shields unless you melee an enemy. With that said, these skulls are an awesome set of collectibles to hunt down. Take note however that in Halo: Combat Evolved and Halo 2, skulls will not appear while playing in Classic Mode. Once all 41 skulls have been collected, this achievement will unlock.

As a cumulative achievement, this will most likely come naturally as you spend time on the Multiplayer portion of the game or even messing around in Custom Game matches. If you desire to work on this quickly, try hanging around the SWAT and Rumble playlists as these will offer fast-paced action where the matches will last, on average, anywhere from three to five minutes.

Alternatively, you can opt to boost this on your own in Custom Games for an even quicker method in obtaining this achievement. In the Custom Games lobby, simply load up Halo: CE's Beaver Creek (gametype does not matter) and begin the match. As soon as the game begins, pause your game, click "End Game" and this will automatically count as a win for you. Once you have successfully won 500 Multiplayer games, the achievement will unlock.

The Long Haul 20
Complete 500 missions or multiplayer games.    (9) 

As a cumulative achievement, this will most likely come naturally as you consistently work on the four Campaigns and partake in online Multiplayer matches or even Custom Game matches. Just like the description says, you must successfully complete the mission or online match in order for progress to count towards this achievement.

Take note that while progress does not count if you quit out of an online match, the best method in obtaining this achievement quickly is to load up a custom game (preferably Halo: CE's Beaver Creek as it loads faster than H2A maps) and immediately end the session when the game begins. This will count as a win towards this achievement. Once 500 missions or multiplayer games have been completed, the achievement will unlock.

Gruntageddon 10
Kill 1000 Grunts.    (1) 

As the lowest ranking species in the Covenant, these enemies are often treated as cannon fodder and will be encountered in small groups of three or five, often led by a single Elite.

Given their pack-like nature, these Grunts will only pose a significant threat when they are confronted in large groups. They generally wield Plasma Pistols and Needlers – two of the weaker Covenant weapons – though some high-ranked Grunts will often carry Fuel Rod Cannons as well. They are the most common enemy found within the game and will appear in nearly every single level of each Campaign. Once you have killed a total of 1,000 Grunts, this achievement will unlock.

Were It So Easy 10
Kill 1000 Elites.    (1) 

Elites are one of the most intelligent and combat-skilled species within the Covenant. Often regarded as pack-leaders, these enemies are usually found roaming around with a group of three to five Grunts, or among their own brethren in groups of two or three.

Unlike most Covenant enemies, Elites are no simple threat to eliminate. They generally wield Plasma Rifles, Carbines, Energy Swords and Fuel Rod Cannons and they also have shields, much like the Master Chief. All of this makes combat with Elites more diverse than ever. You’ll need to expend a significant amount of well-placed shots to strip their shields before they finally topple over to their death. As a general note, firing an overcharge Plasma Pistol shot at an Elite will strip their shields, thus leaving them vulnerable for a quick headshot from a Magnum, Battle Rifle, Covenant Carbine, or DMR.

Elites appear in nearly every level of each Campaign, with the exception of Halo 3; in this Campaign, Elites have allied with the Humans, which means they will not be a present threat in battle. Once you have killed a total of 1,000 Elites, this achievement will unlock.

Scavenger Hunt 10
Kill 1000 Jackals.    (1) 

These savage reptilian mercenaries act as the defensive support troops for the Covenant. They tend to travel in packs of two and prove to be quite a burden in killing if you are not aware of their explicit weakness.

Typically serving as sniper scouts and defensive fighters, Jackals enjoy to keep their distance in battle given their keen perception of sight and hearing. The standard defensive Jackals are simply armed with wrist-mounted energy shields and Plasma Pistols. On the other hand, Jackal Snipers and Rangers are armed with Carbines and Beam Rifles. When dealing with the former variant, try to pick off shots at the small slits in their wrist-mounted shield. This causes them to stumble back, exposing themselves for further attacks such as headshots. The latter variant are vicious and unforgiving so make sure to utilize cover often when dealing with them from afar. Jackals are the second-most common enemy found within the game and will appear in nearly every single level of each Campaign. Once you have killed a total of 1,000 Jackals, this achievement will unlock.

Dankey Kang 10
Kill 1000 Brutes.    (3) 

Brutes are one of the most aggressive species within the Covenant. These ape-like creatures often travel in packs among each other and generally wield their own variant of a Plasma Rifle, as well as Brute Shots and Covenant Carbines. On rare occasion, you will often time encounter Brute Chieftains that carry Fuel Rod Cannons and Gravity Hammers.

Brutes are special in that they are not introduced into the series until Halo 2. Here, they are still formidable forces but it is not until Halo 3 – where Brutes become the main enemy variant – that they use energy shielding just like the Master Chief and Covenant Elites. This shielding makes them a little harder to deal with given their overly aggressive behavior in combat. In addition to this, most Brutes in both games also wear armor plating on their heads, which can prove to be a burden in removing when aiming for headshots. Remember, Brutes do not appear in Halo: Combat Evolved and Halo 4. Once you have killed a total of 1,000 Brutes, this achievement will unlock.

Wyrmslayer 10
Kill 250 Hunters.    (7) 

These creatures are by far the strongest forces in the Covenant. Fitted with a heavy fuel rod cannon in one arm and an impervious shield in the other, Hunters barely flinch when taking damage from your firepower. Hunters are a unique species within the Covenant in that they are actually made up of smaller worm-like organisms. When grouped together, they form the massively armor-plated nightmares players would wish to avoid in combat.

Despite their size, Hunters are very swift on their feat and will also travel with a single other pack member. When dealing with the enemies in combat, the best way to kill them is to get close. When you are in their “personal bubble,” they will charge at you. At this time, quickly step to the side and turn around to spot the exposed orange worms on their back. This is their only weakness, so either melee them or spray your weapon here!

Keep in mind that while Hunters are one of the least-common enemies found within the game, but they do indeed appear in each of the four Campaigns. As a note, Halo: CE's "Truth and Reconciliation" has six Hunters, "Silent Cartographer" has four Hunters, and Assault on the Control Room has six Hunters. These missions are probably the best place to grind out kills by manipulating checkpoints saves since most checkpoints are given to players before battling Hunters. In fact, on Silent Cartographer, players should always receive a checkpoint before reaching the Hunter pair on the path to the security control room. Using the equipped Magnum, you can quickly kill both Hunters, and then restart your checkpoint to grind out the kills. Once you have killed a total of 250 Hunters, this achievement will unlock.

Remove the Bishops From the Board 10
Kill 1000 Watchers.    (9) 

Promethean Watchers are a highly advanced Forerunner A.I. that will only appear in Halo 4. Serving as defense units for Promethean Knights, you can always spot these pesky enemies hovering above their masters. In fact, Knights are the sole source of their spawn, via the carapace on the Knight’s back.

Given their guardian-like nature, they will prove to be very stubborn in battle. They provide covering support with Boltshots, project Hardlight Shields onto Knights, and even revive destroyed Knights in the midst of battle. If that wasn’t enough to prove their worth, Watchers will also redirect any thrown grenades back to you via a gravity displacement beam. With this mind, make sure to take on Watchers from afar with steady-shot weapons such as a Carbine or Battle Rifle. Getting rid of them early in battle will be necessary before focusing your attention on other enemies.

A perfect opportunity to grind out Watcher kills would be during the final mission of the Campaign, Midnight. From the Campaign lobby, go ahead and load up Rally Point Bravo on the aforementioned mission. As you run up the ramp and through the door into the next hallway, there will be four Watchers in this large chamber. You can opt to kill all four with your precision weapon, then reload the checkpoint to grind out the kills. Remember, these Promethean enemies only appear in Halo 4. Once you have killed a total of 1,000 Watchers, this achievement will unlock.

Knightbane 10
Kill 1000 Knights.    (1) 

Promethean Knights are another form of advanced Forerunner A.I. that will only appear in Halo 4. These warriors prove to the most serious threat in battle due to their increased survivability via Watchers, advanced heavy weaponry, and the ability to teleport in combat.

Armed with Light Rifles, Binary Rifles, Scattershots, and even Incineration Cannons, you’ll have to make sure to tackle combat with these warriors in an intelligent manner. Much like Covenant Elites, Knights often lead groups of Promethean Crawlers into battle and have energy shields that recharge at a faster rate than that of Elites. When squaring off against these foes, bring your best; Shotguns and the Noob-Combo will prove to be beneficial.

A perfect opportunity to grind out Knight kills would be during the final mission of the Campaign, Midnight. From the Campaign lobby, go ahead and load up Rally Point Bravo on the aforementioned mission. Continue through the mission normally until you reach the small armory that houses the Gravity Hammer and other UNSC and Promethean weaponry. Here, grab whatever weapon you'd like, perhaps a Scattershot and the Gravity Hammer and proceed through the portal.

When you emerge inside another room, there will be one Knight facing away from you, as well as four other Knights deeper in the chamber. Because the game gives you a checkpoint inside the armory, you can kill all the enemies in this chamber and then restart the checkpoint to continue the grind. Remember, these Promethean enemies only appear in Halo 4. Once you have killed a total of 1,000 Knights, this achievement will unlock.

Dogcatcher 10
Kill 1000 Crawlers.    (1) 

Promethean Crawlers are the third and final advanced Forerunner A.I. that will only appear in Halo 4. These enemies play a similar role to that of Covenant Grunts; however do not underestimate their ability in battle. Their advanced agility and swarming tactics demonstrate just how menacing they truly are when fighting a pack in close-quarters combat.

Crawlers are usually armed with Boltshots, however the stronger variants will often time carry Suppressors and even Binary Rifles. Crawlers enjoy attacking in swarms and even retreating, as a means of luring players into more dangerous combat. Given these harassment tactics, it’s best to face off against Crawlers from afar, picking them off with simple headshots.

A perfect opportunity to grind out Crawler kills would be during the final mission of the Campaign, Midnight. From the Campaign lobby, go ahead and load up Rally Point Bravo on the aforementioned mission. Continue through the mission normally until you reach the small armory that houses the Gravity Hammer and other UNSC and Promethean weaponry. Here, grab whatever weapon you'd like, perhaps a Scattershot and the Gravity Hammer and proceed through the portal.

When you emerge inside another room, there will be five Knights, as well as six to eight Crawlers. Because the game gives you a checkpoint inside the armory, you can kill all the enemies in this room and then restart the checkpoint to continue the grind. Remember, these Promethean enemies only appear in Halo 4. Once you have killed a total of 1,000 Crawlers, this achievement will unlock.

Halo CE: Beat par time on all Halo: CE levels.    (4) 

Before anything, make sure to turn on "Timing HUD" in the Campaign Lobby before starting a mission. In order to beat the Par Time on all ten missions with Halo: CE's Campaign, you will want to take three things into account.

First, play on the Easy difficulty setting so that enemies aren't as dangerous. Secondly, don't bother turning on any skull modifiers in the lobby. Lastly, utilizing the various speed running tactics as shown in Halo: CE's speed running achievement will help immensely in skipping certain firefights and finishing each mission in a considerably less amount of time as normal. With these tips in mind, you should have no problem completing each mission under Par Time.

You can use the checklist below for a reference on each mission’s Par Time:

  • Pillar of Autumn - 15:00 minutes
  • Halo – 20:00 minutes
  • Truth and Reconciliation – 20:00 minutes
  • Silent Cartographer – 15:00 minutes
  • Assault on the Control Room – 15:00 minutes
  • 343 Guilty Spark – 15:00 minutes
  • The Library – 25:00 minutes
  • Two Betrayals – 20:00 minutes
  • Keyes – 15:00 minutes
  • The Maw – 15:00 minutes

Overall, just remember to play on the lowest difficulty setting and try rushing past as many firefights when possible. Once you beat the Par Time for all ten missions, this achievement will unlock.

Before anything, make sure to turn on "Scoring HUD" in the Campaign Lobby before starting a mission. In order to achieve the Par Score on all ten missions with Halo: CE's Campaign, you will want to take three things into account.

First, manually activate the Black Eye, Famine, Fog, Grunt Birthday Party, Famine, and Iron skulls in the lobby and set the difficulty to Heroic. Unfortunately, Par Scores cannot be obtained in Co-Op play, so just stick with a solo playthrough of each mission here.

Secondly, you will want to try completing the mission as quickly as possible (finishing under Par Time will give a x3 multiplier to your final score) while still killing everything on the battlefield via headshots and multikills; do not skip firefights or leave anyone alive. Lastly, if you do happen to run over Par Time, try picking up the pace as the time multiplier will begin to reduce significantly!

You can use the checklist below for a reference on each mission’s Par Score:

  • Pillar of Autumn - 17,000
  • Halo – 12,000
  • Truth and Reconciliation – 19,000
  • Silent Cartographer – 18,000
  • Assault on the Control Room – 18,000
  • 343 Guilty Spark – 17,000
  • The Library – 25,000
  • Two Betrayals – 16,000
  • Keyes – 18,000
  • The Maw – 18,000

Once you beat the Par Score for all ten missions, this achievement will unlock.

Halo CE: Activate all Halo: CE Terminals.     (9) 

In total, there are 10 terminals spread across each of the 10 missions within the Campaign that must be activated for this achievement. These terminal stations are well-hidden and usually off the main path of your objective, so it will take a keen eye and some exploration in order to track them down. You’ll know when you’ve found a terminal by the spotting a bright yellow hologram with a flashing panel. Simply approach the panel and hold the action button to activate it.

Take note that you do not necessarily need to watch the entire terminal because progress towards this achievement registers as soon as it’s activated. It is highly recommended to spend the two to three minutes in observing each terminal though. Once activated, they will provide crucial backstory to the Halo Universe. Also, take note that terminals will not appear while playing in Classic Mode. Once all 10 terminals have been activated, this achievement will unlock.

Halo CE: Find and claim all Skulls in Halo: CE.     (10) 

In total, there are 13 skulls scattered across each of the 10 missions in the Campaign that must be collected for this achievement. These skull collectibles are extremely well-hidden and come in the appearance of an actual human skull. At times, you will find that some are only obtainable for reaching obscure locations via grenade jumps and other advanced tactics. Needless to say, it will take a tremendous amount of exploring to locate these skulls.

These skulls are a unique collectible in that they act as significant gameplay modifiers. When activated via the Campaign Lobby Menu, skulls will alter the way the Campaign is played by either removing your HUD, granting infinite ammo and grenades, or even disabling the recharge ability of your shields unless you melee an enemy. With that said, these skulls are an awesome set of collectibles to hunt down. Take note however skulls will not appear while playing in Classic Mode. Once all 13 skulls have been collected, this achievement will unlock.

Living Legend 30
Halo CE: Complete every level of the game on Legendary difficulty.      (31) 

This achievement will unlock once all ten missions of the Halo: Combat Evolved Campaign have been successfully completed on either a Solo Legendary playthrough or Cooperative Legendary playthrough. There are multiple methods in tackling the missions of the Campaign, but keep these general tips in mind when playing:

  • Utilize the Pre-Noob-Combo (Plasma Pistol/Magnum Pistol) at all times when facing Elites; an overcharged Plasma Pistol shot will drain their shields, and a quick Magnum round to the cranium will down the warriors easily
  • Utilize ground vehicles – Warthogs, Scorpions, and Ghosts – as frequently as possible; their firepower in missions such as Halo, Silent Cartographer, and Assault on the Control Room will help clear out areas quickly and you can even drive past enemy encounters if the mission allows for it
  • When facing Hunters, get close enough so that they charge at you, allowing time to side step their attack; when the orange flesh on their back is exposed, shoot it, as this is their only weak spot
  • When squaring off against the Flood, keep a Shotgun on hand; it’s the best weapon to use against the parasite
  • Don’t neglect the basics of using cover; when your shields drop down, hide behind a wall or crouch behind an object before charging back out into battle
  • Try exploring the levels and finding alternate routes behind or around the enemies; this can help save time by skipping major firefights on levels such as Truth and Reconciliation, Silent Cartographer, and even The Library.

Overall, because seasoned Halo players will be familiar with both level design and enemy behavior, completing the entire Campaign on Legendary will be quite easy. Once all the missions in Halo: Combat Evolved have been completed on the Legendary difficulty setting, this achievement will be yours.

Overshields are for Sissies 10
Halo CE: Complete the level The Pillar of Autumn on Legendary without picking up an overshield.     (6) 

Please refer below to "Walk It Off" for more information.

Walk It Off 10
Halo CE: Complete The Pillar of Autumn on Legendary without picking up a health kit.     (7) 

The Pillar of Autumn is without a doubt one of the shortest missions within the entire Campaign. You’ll also come to realize that given the nature of the Autumn’s design structure, it’s also the most confined mission in terms of navigable space for firefights. With that said, you’ll need to proceed through the entire mission very carefully in order to avoid taking any health damage.

On the bright side, overshields will only ever be located inside the Covenant drop pods. This means that so long as you do not purposely step inside an enemy pod and deliberately pick up an overshield, you’ll have no issues obtaining the first achievement. As for not picking up health kits, you’ll want to utilize grenades as often as possible when taking on groups of Covenant enemies inside the Autumn in order to avoid direct confrontations and thus taking health damage. Since the corridors here are tight, a single grenade can usually flush out an entire room or hallway of enemies with ease.

To maximize the effectiveness of grenades on this mission, it would be wise to activate the Bandana skull in the Campaign lobby as this provides unlimited ammo and grenades. Another strategy is to tackle the mission cooperatively with another player. This second method is great since your partner can go forth and clear out all the enemies while you stay behind and avoid any and all crossfire between your partner and the Covenant. Either way, if you complete the mission without picking up a single health kit or overshield, both achievements will unlock after the concluding cutscene.

How Pedestrian 10
Halo CE: Complete Halo without entering a vehicle.    (7) 

This mission will prove to be extremely tedious without using the Warthog provided after the first major firefight with Marine allies. Fortunately, the vehicle’s firepower isn’t necessary and it’s not even that useful for the later firefights, so traveling on foot shouldn’t be too bad.

The only difficult aspect of this achievement is the large gap inside the first tunnel of the cave-like structure. The way to cross this massive gap without the usage of a vehicle is to utilize a grenade jump. As such, you’ll need a frag grenade or plasma grenade at this point in order to advance through the mission. When you reach this gap, simply toss the grenade on the ledge, take a few steps back, and then time your forward jump so that the grenade explodes as you leave the ground, thus propelling your forward over to the other ramp.

If you’re playing cooperatively, only one person has to perform the grenade jump. The second player can be killed via friendly fire, which results in their spawn on the opposite side of the gap. Overall, once your rescue all three groups of Marines and are picked up via Pelican, the achievement will unlock after the concluding cutscene.

That Just Happened 10
Halo CE: Complete The Library on Heroic or Legendary difficulty without dying.     (13) 

While this achievement seems tough, it’s actually quite simple so long as you choose effective weaponry to use against the Flood and avoid the Carrier Forms at all costs. As a recommendation, try to pick up a Shotgun and Needler during the first few firefights. The former weapon is perfect for taking on the Flood in close-quarters while the latter is useful when at a ranged distance. In addition to this, if the Bandana skull is activated for this mission, the unlimited ammo and grenades will prove to be extremely beneficial.

Progress through the level and make sure to avoid the Carrier Forms. Once they get close, they will fall onto the ground and explode. These explosions will often time kill you if your shields or health are low. Other than that, there are also two instances where Combat Forms are wielding Rocket Launchers, so be careful not to be caught in their line of fire. Once the final cutscene concludes, the achievement will unlock providing you did not die at all during the mission.

Look Out for the Little Guys 10
Halo CE: Complete Two Betrayals on Legendary difficulty without killing any Grunts.     (5) 

During this mission, there will be a fair amount of Grunts that will get in your way when attempting to reach your three main objectives. Since the Flood and the Covenant will be frequently fighting during the mission, try to sit back and wait out the firefight. The Flood will almost always kill the Covenant, thus reducing the amount of work necessary in trying to slip by enemy Grunts without killing them. In addition to this, the majority of the Grunts only appear during the first half of this mission.

If you are playing with a Co-Op partner, you can always try staying back and having your partner clear the rooms and areas with Grunts before moving forward towards the objectives. This makes things a little easier, though you will have to replay the mission twice for both players to unlock the achievement. Once the final pulse generator has been disabled, the achievement will unlock providing you haven’t killed a single Grunt.

Leave It Where It Lay 10
Halo CE: Complete Two Betrayals on Legendary difficulty without picking up a new weapon.     (9) 

At the start of this mission, you will be equipped with a Plasma Pistol and Shotgun. In order to obtain this achievement, you cannot switch out either weapon at any point in the mission. Fortunately, these weapons are rather useful against the both the Covenant and the Flood, and since both factions will often time battle one another, this reduces the ammo you need to expend on the enemy.

Attempting this achievement with a Co-Op partner is recommended as one player can swap out their starting weapons for more something more effective like a Rocket Launcher or Needler. In addition to this, if one player dies, they will respawn with an Assault Rifle, though this does not void the achievement. Once the final pulse generator has been disabled, the achievement will unlock providing you haven’t swapped out either of your weapons during the mission.

Tying Up Loose Ends 10
Halo CE: Kill every Elite on the level Keyes on Heroic or Legendary difficulty.    (4) 

As one of the most tedious mission-specific achievements in the game, you’ll need to kill every single Elite on this mission before the achievement unlocks. The worst part about this task is that the achievement only unlocks after climbing inside the Covenant Banshee, so there’s no way of knowing if all Elites have been killed prior to finishing the mission.

The good news here is that for the first half of the mission, the Flood and the Covenant are fighting quite frequently, meaning most of the Elites will die by the hand of the parasite. Once you return to the ship via a gravity lift and find the Proto-Gravemind however, all the remaining Elites in the mission – about twenty plus – will be Spec-Op units. As you make your way from your current position to the hanger bay, make sure to inspect every single nook and cranny inside all the hallways. There are three floors total with many hallways so take it slowly and don’t leave any room untouched. Once you’re confident all the Elites in the hanger bay corridors have been killed, climb inside the Banshee and the achievement will unlock.

A Fine Choice 10
Halo CE: Complete a Halo: CE playlist.    

Please refer below to "Excellent Taste" for more information.

Excellent Taste 20
Halo CE: Complete three Halo: CE playlists.    (1) 

In Halo: The Master Chief Collection, Campaign playlists make their debut as a means of experiencing a particular set missions that all share a common thread. Hand-crafted by the developer, some of these playlists are unique, such as all the vehicle-realted missions or all Flood-related missions within the Campaign. There's also playlists for Easy Campaign, Normal Campaign, Heroic Campaign, Legendary Campaign, and LASO Campaign.

Since the LASO Campaign playlist must be completed for a separate achievement, all that is required is to complete a minimum of two other playlists for this achievement. In Halo: Combat Evolved, the shortest playlists - which also prove to be quite enjoyable - are the following:

  • Vehicle Playground - Halo, The Silent Cartographer, Assault on the Control Room
  • Daring Escapes - The Pillar of Autumn, The Truth and Reconciliation, The Maw
  • A New Threat - 343 Guilty Spark, The Library, Two Betrayals

Simply pick and choose whichever three Campaign playlists you'd like to work on and once they have all been successfully completed, this achievement will be yours.

Like a Fine Wine 30
Halo CE: Complete the Halo: CE LASO Campaign playlist.    (61) 

As with any of the playlists dedicated to the Halo: CE Campaign, the LASO Campaign playlist will task players in completing all ten missions on the Legendary difficulty with all skulls on. Take note however that the developer has selected a preset number of skulls for this Campaign, so all the skull modifiers aren’t technically activated. It is also worth mentioning that this achievement can be earned in either Solo or Co-Op play.

What’s more, it’s important to remember that only scoring skulls will be activated. These generally reward players with higher score multipliers and bonuses to base enemy values (for Par Score achievements). Non-scoring skulls on the other hand are sometimes neutral, such as Grunt Birthday Party, or considered “cheat skulls” such as Bandana and Scarab Gun. Below, you can get a glimpse of all the skulls that will be activated in the Halo: CE LASO Campaign playlist.

  • Black Eye - Your shields only recharge when you melee enemies. Bash your way to better health!
  • Boom - Explosions have twice the damage radius. Light fuse, run away.
  • Fog - The motion tracker is disabled. You'll miss those eyes in the back of your head.
  • Eye Patch - Auto aim features disabled for all weapons. You'll miss it when it's gone.
  • Famine - Weapons dropped by AI have half the ammo they normally would. You might want to pack an extra magazine.
  • Foreign - Covenant weapons: How do they work? Players cannot pick up or use Covenant weapons.
  • Grunt Birthday Party – Grunt headshots lead to glorious celebrations.
  • Grunt Funeral - Grunts die in a blaze of glory. And plasma.
  • Iron - Death carries a heavy price. Dying in co-op resets you at your last saved checkpoint. Dying solo restarts the level.
  • Malfunction - Every time you respawn, a random element of your HUD is disabled.
  • Mythic - Enemies have increased health.
  • Recession - Every shot is worth twice the ammo. Save those bullets, playa.

As a few general tips, keep the following suggestions in mind when tackling this achievement. First, take combat slowly and try picking off enemies from afar with short controlled bursts. Since ammo costs twice as much, weapons will have less ammo upon pick-up, and you won’t be able to pick up Covenant weapons, you’ll need to utilize the firepower and magazine size of UNSC weapons such as the Magnum, Assault Rifle, Sniper, and Shotgun. Secondly, since your shields won’t recharge unless you melee an enemy, it may be smart to occasionally tackle weaker enemies such as Grunts head-on when necessary. Lastly, explosions are twice as large and Grunt corpses create secondary explosions on the battlefield so make use of grenades often when flushing out large groups of enemies in confined spaces.

With enough persistence and skill, the Halo: CE LASO Campaign playlist shouldn’t be too hard. As previously mentioned, the developer has picked and chose very specific skulls here, and it would appear that some of the harder skull modifiers, such as Iron, Blind, and Mythic, aren’t present here. Just take the missions slowly and once the tenth mission has been completed through this playlist, the achievement will unlock.

You Are The Weapon 5
Halo CE: Kill a Hunter with one pistol round.    (10) 

Though this achievement can be completed on any mission that houses a duo of Hunters, The Silent Cartographer is probably the best mission to attempt this achievement. On this mission, once you are required to head on over to the security control room, you will fight a decent amount of Covenant troops while ascending a grassy hill. After this firefight, you’ll find yourself in an open valley where this mission’s terminal is located. Here, you’ll also find a nasty pair of Hunters ready to attack.

Since you begin this mission with a Magnum by default, it is important that you kept it up to this point. When facing off against the Hunters, you’ll need to position yourself a few feet directly ahead of the creature. At this point, the Hunter will lunge forward and charge at you. When they do this, you’ll need to sidestep to the left or right in order to dodge the assault. Quickly turn around and aim your Magnum at the patch of exposed, orange flesh on the Hunter’s back. With a single Magnum shot at this weak spot, the Hunter will immediately topple of to his death, thus unlocking the achievement.

Madrigal Debut 5
Halo CE: Trigger a hidden music cue in Halo: CE.    (10) 

This Easter Egg can be found in the mission, Assault on the Control Room.

The hidden music cue in this game is none other than Siege of Madrigal, a song that original Halo developer Bungie used in one of their previous video games. When standing in a specific spot on the aforementioned mission, you will be able to hear the faint melody to the song. Be sure to follow the guidelines listed below, since it’s a slightly complicated process to trigger the hidden music cue.

  • The music cue can be found on the pyramid structure at the end of the level
  • There are three brackets on the large tower above the control room entrance
  • You will need to land on the second one with a Banshee
  • A Banshee can be stolen on the snowy bridge during the middle of this mission
  • Once you have landed on the bracket, face the cliff and go to the right side of the bracket
  • There should be a part of the bracket that points towards the cliff, then slopes down steeply
  • From the flat part of the bracket, move towards the steeply sloped portion slowly
  • You will eventually hear the song

Once you have successfully reached the required spot, Siege of Madrigal will be triggered and the achievement will unlock.

My Buddy Chips 5
Halo CE: Fight alongside Chips Dubbo and listen to his words of wisdom.   (4) 

Private First Class Chips Dubbo is an Australian Marine that serves with the UNSC during the events of the Halo games. You can usually spot him within a firefight due to his thick Australian accent and witty remarks. With that said, this achievement is actually quite simple as there doesn't seem to be a definitive location of where Chip Dubbo is. Rather, the achievement tends to unlock almost every single time upon running towards the bridge in The Pillar of Autumn, escaping via the life pod in The Pillar of Autumn, reaching the first group of Marines in Halo, or during the hanger bay fight in The Truth and Reconciliation. Overall, this achievement will more than likely come naturally to players during their time on the Campaign, so don't worry about needing to do anything special in order to find Chips or trigger a special line of dialogue.

No Smoking 5
Halo CE: Disapprovingly look at Captain Keyes' abandoned pipe.   (13) 

This Easter Egg can be found in the mission, Keyes.

During this mission, continue as you would normally towards your primary objective until you re-enter the Truth and Reconciliation via an energy lift. Once back on board the Covenant ship, you’ll need to make you way towards the command center. Here, you’ll find Captain Keyes in an unfortunate state: assimilated by the Proto-Gravemind.

After the Master Chief retrieves the Captain’s neural implants via a cutscene and fends off against the waves of Flood and Covenant Spec Ops units, search the floor of the command center’s console platform where the Proto-Gravemind’s tentacles are scattered about. You will eventually spot one of the overhanging tentacles holding the Captain’s infamous tobacco pipe. Simply stare at the pipe for a few seconds and this achievement will unlock.

T-Rex 10
Halo CE: Find the hidden Rex sign on The Maw.    (9) 

This Easter Egg can be found in the mission, The Maw.

During the Warthog escape sequence at the end of this mission, Cortana will eventually warn you of a large gap in the runaway. At this point, floor it off the ramp and veer the Warthog off to the right or left so that you land on one of the sides of the platform below. From here, you can jump to the top of the tunnel where you would have originally landed if you nailed the Warthog jump; you’ll see a flaming canister in this location. Simply walk into the open corridor next this canister and inside you will see the name “Rex” spelled out in blood along the wall. The achievement will unlock as soon as you step foot in this corridor.

Thirsty Grunt 5
Halo CE: Listen to the Thirsty Grunt talk about his eating habits.   (8) 

This Easter Egg can be found in the mission, The Maw.

During the Warthog escape sequence at the end of this mission, you will eventually reach an outdoor bridge where Foe Hammer is meant to pick you up. After your pilot is shot down by Covenant Banshees, continue driving your Warthog through the tunnel just ahead. After descending a small hill inside this tunnel, there will be a narrow passageway on the right side. Drive the vehicle through this small tunnel and there will be yet another open passageway on your right.

At the end of this second tunnel, there will be a lonely Grunt standing around a few dead Flood bodies. Get out of the Warthog and approach the Grunt. After a few seconds he will repeat the following line of dialogue, “Good thing that Food Nipple's waiting for me at the starship 'cause man, whew, have I worked up a big, grunty thirst!” After the Grunt finishes his line of dialogue, the achievement will unlock.

Megg 10
Halo CE: It's a sign.    (12) 

This Easter Egg can be found in the mission, The Pillar of Autumn.

The hidden “sign” in this mission is a bloody heart made of bullet holes in the shape of an “M” that can only be discovered under a series of nearly impossible feats. This Egg was created by the original lead designer of the game as a gift for his girlfriend whose name was Meg. Be sure to follow the guidelines listed below in order to reach this hidden Egg.

  • Start The Pillar of Autumn on the Legendary difficulty (you must be playing alone)
  • After you gain control of the Master Chief, walk toward the canisters behind you
  • Crouch jump on top the yellow canister and then jump off
  • Move through the level as normal until you get to the bridge of the Autumn
  • Trigger the cinematic by walking towards Captain Keyes
  • Once he hands you the Magnum, go through the exit and kill the three Grunts
  • Head back into the bridge and kill Captain Keyes
  • This will trigger a squad of "Invincible Marines" out of the previously locked door that was on the right side of the bridge’s exit
  • As Cortana finishes saying, "John-117 has gone rampant," a second door (right behind the first locked door) unlocks
  • Wait until the marines crowd one side of the bridge
  • Run past them and into the previously locked door

Once you enter this second room, walk through the entire hallway. At the end of the room, look up towards the ceiling and shine your flashlight in Classic Mode. You will see the “M” shot into the ceiling and the achievement will then unlock.

Get Me Out of Here! 5
Halo CE: Ride in a Pelican for several seconds on the level 343 Guilty Spark.   (15) 

This Easter Egg can be found in the mission, 343 Guilty Spark.

As soon as this mission begins and you gain control of the Master Chief, turn around and head towards the nose of the Pelican dropship. From here, use the small rock in front of the ship and jump onto the cockpit. As the Pelican begins to ascend, you’ll want to walk forward and stay on for as long as possible before you’re automatically forced off the Pelican. After a few seconds of staying on top of the dropship, the achievement will unlock.

Feet Firmly Planted 10
Halo CE: Complete a level without jumping.    (12) 

The second mission, Halo, is most likely the best mission to attempt this achievement given the fact that it's not too long and most of this mission will take place driving a Warthog. Unlike the other Campaign missions, which take place inside structures (The Pillar of Autumn, The Truth and Reconciliation, The Maw, etc.) that require jumping in order to reach objectives and bypass firefights, such possibilities will not occur on Halo.

On this mission, you’ll want to utilize a mix of both grenades and your Assault Rifle/Magnun when taking on groups of Covenant enemies. Since most of the areas where the Marines are located have tight rooms or rocks formations, a few well-placed grenades can usually flush out an entire batch of enemies as they are exiting their dropship. As a note, it may be wise to activate the Bandana and Boom skulls for their beneficial effects of infinite ammo/grenades and increased explosive blasts. If you are successful in completing the mission without jumping whatsoever, the achievement will unlock after the concluding cutscene.

Before and After 10
Halo CE: Complete every level of the game having seen it in both classic and remastered mode.    (8) 

For this achievement, all that it necessary in order to experience the game in both modes is to switch between Classic Mode and Remastered Mode once or twice for all ten missions within the Campaign. To do this, simple tap the view button on the controller and this will toggle between the two modes with nearly no delay whatsoever.

You may end up finding yourself naturally switching between modes as you explore the vast landscapes and structures of each mission. Thus, this achievement may come naturally without even thinking about it. Just keep in mind that you'll need to toggle the visuals once or twice per mission in order to make progress towards this achievement. Once all ten missions have been seen in both Classic Mode and Remastered Mode, this achievement will finally unlock.

He's Unstoppable 10
Halo CE: Complete any level on Heroic difficulty or higher without taking health damage.     (9) 

The Pillar of Autumn is without a doubt one of the best missions to attempt this achievement given the fact that it’s the shortest mission within the entire Campaign. You’ll also come to realize that given the nature of the Autumn’s design structure, it’s also the most confined mission in terms of navigable space for firefights. This provides for an excellent tactic in flushing out rooms with grenades if the Bandana, Boom, or Grunt Funeral skulls are activated.

As such, make sure to utilize grenades as often as possible when taking on groups of Covenant enemies inside the Autumn in order to avoid direct confrontations and thus taking health damage. Since the corridors here are tight, a single grenade can usually flush out an entire room or hallway of enemies with ease. Just make sure to stay back when tossing the grenades if Boom or Grunt Funeral have been activated.

An alternative strategy for this achievement is to tackle the mission cooperatively with another player. This method is great since your partner can go forth and clear out all the enemies, while you stay behind and avoid any and all crossfire between your partner and the Covenant. If you are successful in completing the mission without taking any health damage whatsoever, the achievement will unlock after the concluding cutscene.

A Day To Remember 5
Halo CE: Play Halo: CE on the 15th of any month.     (2) 

As a means of celebrating the launch date of the original Halo: Combat Evolved, this achievement simply tasks you to play the aforementioned game on the 15th of any month. This can be done by playing any of the ten Campaign missions and even messing around in a Custom Game with friends or hopping online and playing a match on a Halo: Combat Evolved map. Overall, this achievement is pretty straightforward and can be obtained with minimal effort of your part.

Back In The Day 5
Halo CE: Play a CTF custom game on Blood Gulch with 4 players on the same console. Tri-tip optional.     (55) 

Before you can attempt this achievement, you must have a total of four Xbox One controllers on hand. Once you have this number of controllers, go ahead and boot up a Custom Game under Halo: Combat Evolved.

In the map select option, you will want to choose Blood Gulch and then set the game type of Capture the Flag or Capture the Flag Classic. Before launching the game, power up the three extra controllers and sign them all into guest accounts. Now you can start up the match and as soon as it begins, this achievement will immediately unlock without any issue.

Pacifist 10
Halo CE: Finish The Silent Cartographer without shooting, grenades, melee, dying or restarting.    (10) 

Although this achievement sounds intimidating, this ten minute mission can easily be completed under such constraints when playing on the Easy difficultly setting. Take note that it has been reported to not unlock during Co-Op play, so it's best to perform it on your own.

As soon as the mission starts, turn to your left and head down the beach until you reach the overturned Warthog. From here, proceed up the hill to your right, leading you deeper into the island and eventually into the security room of an underground complex. After disengaging the control room's security mechanism, exit the complex, grab the overshield on the ground to your right, and drop down the cliff onto the beach. Hope inside the nearby Warthog and drive back to the map room's entrance.

Once there, you'll need to reach the bottom level of the facility and activate the cartographer before you're demanded to return topside. When you finally reach the top floor, push past the Elite wielding the Energy Sword, Hunter duo, and Stealth Elites. Now wait until the Pelican lands on the platform and when it does, get inside and the mission will end. If you managed to survive the mission without shooting, using grenades, melee attacking, dying, or restarting, the achievement will unlock.

Wraith Hunter 10
Halo CE: Destroy four Wraith tanks in Assault on the Control Room with the Scorpion tank.    (8) 

In total, there are exactly four Covenant Wraiths within this mission that must be destroyed via the Scorpion Tank for this achievement. Once you reach the ground level of the canyon and travel outside, you’ll spot an overturned Warthog and a squad of Marines taking mortar fire from a Wraith on the other side of the valley. At this point, get inside the Warthog, drive down the valley past the Wraith, and into the next valley where you’ll find a Scorpion Tank.

Once you jump inside the Scorpion, the Wraith from before will be creeping up behind you, so turn the turret and destroy the Covenant vehicle. Now proceed forward into the next valley and destroy the second Wraith here. You’ll also have to destroy the third Wraith that’s stationed above the tunnel entrance. Once you travel through the underground tunnel and emerge into another snowy valley, proceed past the spire and you’ll spot the fourth and final Wraith accompanied by a pair of Hunters. After destroying this last Wraith, the achievement will unlock.

NOTE: Wraith kills cannot be shared when playing cooperatively, meaning only one player can get this achievement.

Close Quarters Combat 10
Halo CE: Complete The Truth and Reconciliation with at least four rounds left in your Sniper Rifle.    (3) 

At the start of this mission, you are automatically equipped with a Sniper Rifle that holds about forty-eight rounds. Fortunately, the first half of the mission takes place outdoors and this is the only time the Sniper Rifle will be useful. Once you’re inside the Truth and Reconciliation, the Sniper is rendered useless which means forty-eight rounds should be just enough for the outdoor portion of the mission.

Overall, when using the Sniper Rifle, be sure to pick your shots wisely. Headshots will be key in killing Grunts, Jackals and Elites from afar. When engaged in close-quarter combat, utilize grenades, melee attacks and any other secondary weapon so that Sniper Rifle ammo is not mindlessly used.

Playing this mission cooperatively may also be a good strategy for this achievement, as it cuts the workload of one player having to use their Sniper Rifle during the first half of the mission. So long as there are at least four rounds left in the aforementioned weapon before climbing aboard the Covenant dropship with Captain Keyes, the achievement will unlock.

Note: Activating the Bandana skull for this mission results in obtaining infinite ammo for any weapon you pick up or have equipped. With that said, you can activate this skull in the Campaign lobby and just carry the Sniper Rifle all the way through the mission for this achievement.

This Side Up 10
Halo CE: Complete the Warthog ride of The Maw without being forcibly ejected from your vehicle.    (4) 

Once you destroy the four reactors inside the engineering bay and take the elevator up to vehicle station, grab the first Warthog on your right. From here, you’ll need to escape the Autumn without ever flipping over your Warthog or being forcibly ejected from your seat. This achievement is actually very easy so long as you are a competent vehicle driver. Also, it's worth mentioning that if you do flip your vehicle at any point and are forcibly ejected from the seat, you can always restart your checkpoint as it will not void the achievement.

Each of the four hangers you drive through will have a different layout, meaning you’ll need to adapt quickly as you drive past the explosions and firefights between Covenant and Flood. For the first hanger, driving straight down the middle is the safest route. Once you reach the second and third hanger bays, stick to the ramps on either side since the middle path will be blocked. In the final hanger, you’ll have to slalom around the pillars on the middle path, which can prove to be a little tedious and dangerous.

After this fourth hanger, the ride should be a little smoother until Cortana warns you of a large jump ahead. The best strategy in tackling this jump is to line up the Warthog evenly with the ramp and floor it, then ease up on the acceleration when you’re mid-flight. This will prevent your vehicle from tipping forward, thus ensuring you’re not ejected from your seat when you land. After the jump, you’ll eventually need to exit the Warthog and sprint down the runway and past some Flood in order to reach the Longsword. If you managed to stay planted inside the Warthog during the entire ride, the achievement will unlock once you get inside the Longsword.

All According to Plan... 10
Halo CE: Kill the first group of enemies on The Truth and Reconciliation without being detected.    (10) 

As soon as the mission begins, head to your right near the cliffside edge and station yourself in between the “U” shaped rocks. Here, you can avoid being detected given the distance between yourself and the enemy.

Now you will want to pick off all the roaming Grunts, the two Jackals, and the single Elite (sometimes there are two) from this position. Once these enemies have been dealt with and you cannot see any other Covenant forces, inch your way up the cliffside path to your right and peek towards the left. Here, you will spot a single Grunt manning a Shade turret so be ready to kill him.

At this point, slowly scan the valley below and make sure there aren’t any red blips on your motion tracker. If you’ve successfully killed the initial group of enemies stationed in this valley without being spotted, a music cue will begin, your Marines will disperse into the valley, and the achievement will unlock.

Note: At no point should you ever drop down from the cliffside edge. If you do, the Marines are scripted to move into the valley and they will blow your cover. If this happens for any reason, simply restart the mission.

Beachhead 10
Halo CE: Storm The Silent Cartographer beach with no Marine casualties on Heroic or Legendary.     (5) 

As soon as this mission begins, two Pelicans will land on the beach, dropping off two groups of Marine allies. Here, you will have to clear the entire beachhead without any allies dying. Unfortunately, there are several Grunts, Jackals and Elites stationed directly ahead defending the beach, so you’ll need to act quickly since the Marines tend to rush forward and take a lot of damage from the Covenant forces. There’s also a group of three to four Grunts hiding behind a rock formation to the left of the drop-off point. As if that weren’t enough, after clearing the initial wave of enemies, two more Elites and a trio of Jackals will ambush you as you move further down the beachhead.

With all this said, the Magnum and Frag grenades will prove to be extremely beneficial here. As soon you gain control of the Master Chief, quickly pick off the three to four Grunts on the left and then start lobbing grenades towards the Covenant forces on the right. Activating the Bandana and Boom skulls will help here as they grant infinite grenades and double the blast radius of all explosions.

Note that if you move quickly and get in front of your Marines, you should be able to flush out the enemies along the beachhead before any of your allies take a single hit. Once the beachhead is secured and the Warthog is delivered, the achievement will unlock.

No-Fly Zone 10
Halo CE: Destroy three of the four Banshees on Halo during a single play-through.    (9) 

During the second mission, Halo, there are a total of four Covenant Banshees that can be found soaring high in the air. The first two will attack you immediately after crossing the long bridge-like structure in the beginning of the mission. Unfortunately, destroying one Banshee will usually cause the second to flee. If you want to try destroying both Banshees here, shoot each of them with the Assault Rifle until their wings are smoking, then use the Magnum to finish off each Banshee quickly.

The second pair of Banshees will attack you much later on after saving the first life pod of Marines and traveling across the open canyon. The Banshees here will not flee at all, so use any weapon you currently have to make short work of them. After three Banshees have been destroyed in this mission, the achievement will unlock.

Before anything, make sure to turn on "Timing HUD" in the Campaign Lobby before starting a mission. In order to beat the Par Time on all thirteen missions with Halo 2's Campaign, you will want to take three things into account.

First, play on the Easy difficulty setting so that enemies aren't as aggressive in combat. Secondly, don't bother turning on any skull modifiers in the lobby. Lastly, utilizing the various speed running tactics as shown in Halo 2's speed running achievement will help immensely in skipping certain firefights and finishing each mission in a considerably less amount of time as normal. With these tips in mind, you should have no problem completing each mission under Par Time.

You can use the checklist below for a reference on each mission’s Par Time:

  • Cairo Station - 15:00 minutes
  • Outskirts – 15:00 minutes
  • Metropolis – 15:00 minutes
  • The Arbiter – 15:00 minutes
  • The Oracle – 25:00 minutes
  • Delta Halo – 15:00 minutes
  • Regret – 15:00 minutes
  • Sacred Icon – 15:00 minutes
  • Quarantine Zone – 15:00 minutes
  • Gravemind – 20:00 minutes
  • Uprising – 15:00 minutes
  • High Charity – 15:00 minutes
  • The Great Journey – 15:00 minutes

Overall, just remember to play on the lowest difficulty setting and try rushing past as many firefights when possible. Once you beat the Par Time for all thirteen missions, this achievement will unlock.

Before anything, make sure to turn on "Scoring HUD" in the Campaign Lobby before starting a mission. In order to achieve the Par Score on all ten missions with Halo 2's Campaign, you will want to take three things into account.

First, manually activate the Anger, Famine, Fog, Grunt Birthday Party, Sputnik, and Thunderstorm skulls in the lobby and set the difficulty to Heroic. You will definitely want to activate the Jacked skull on any mission that DOES NOT contain ground vehicles; this includes Cairo Station, The Arbiter, The Oracle, Regret, Sacred Icon, Gravemind, and High Charity. Activating this skull adds an additional 1.20x multiplier and since these missions do not have ground vehicles, it's essential a "free" multiplier since the skull's effects are nonexistent.

Unfortunately, Par Scores cannot be obtained in Co-Op play, so just stick with a solo playthrough of each mission here. Secondly, you will want to try completing the mission as quickly as possible (finishing under Par Time will give a x3 multiplier to your final score) while still killing everything on the battlefield via headshots and multikills; do not skip firefights or leave anyone alive. Lastly, if you do happen to run over Par Time, try picking up the pace as the time multiplier will begin to reduce significantly!

You can use the checklist below for a reference on each mission’s Par Score:

  • Cairo Station - 14,000
  • Outskirts – 8,000
  • Metropolis – 9,000
  • The Arbiter – 7,000
  • The Oracle – 16,000
  • Delta Halo – 10,000
  • Regret – 8,000
  • Sacred Icon – 7,000
  • Quarantine Zone – 7,000
  • Gravemind – 11,000
  • Uprising – 9,000
  • High Charity – 9,000
  • The Great Journey – 8,000

Once you beat the Par Score for all thirteen missions, this achievement will unlock.

NOTE: Be sure to utilize THIS LINK if you need further assistance with obtaining the Par Score achievements for Halo 2 or any of the three other games. Be sure to sift through the various informative posts to garner a better understanding of which specific skull sets to use on specific missions of each Campaign, especially Halo 2.

Halo 2: Activate all Halo 2 Terminals.     (7) 

In total, there are 13 terminals spread across each of the 13 missions within the Campaign that must be activated for this achievement. These terminal stations are well-hidden and usually off the main path of your objective, so it will take a keen eye and some exploration in order to track them down. You’ll know when you’ve found a terminal by the spotting a bright yellow hologram with a flashing panel. Simply approach the panel and hold the action button to activate it.

Take note that you do not necessarily need to watch the entire terminal because progress towards this achievement registers as soon as it’s activated. It is highly recommended to spend the two to three minutes in observing each terminal though. Once activated, they will provide crucial backstory to the Halo Universe. Also, take note that terminals will not appear while playing in Classic Mode. Once all 13 terminals have been activated, this achievement will unlock.

Trophy Collector 20
Halo 2: Find and claim all Skulls in Halo 2.     (11) 

In total, there are 15 skulls scattered across each of the 13 missions in the Campaign that must be collected for this achievement. These skull collectibles are extremely well-hidden and come in the appearance of an actual human skull. At times, you will find that some are only obtainable for reaching obscure locations via grenade jumps and other advanced tactics. Needless to say, it will take a tremendous amount of exploring to locate these skulls.

These skulls are a unique collectible in that they act as significant gameplay modifiers. When activated via the Campaign Lobby Menu, skulls will alter the way the Campaign is played by either removing your HUD, permanently cloaking enemies, or even disabling the recharge ability of your shields unless you melee an enemy. With that said, these skulls are an awesome set of collectibles to hunt down. Take note however skulls will not appear while playing in Classic Mode. Once all 15 skulls have been collected, this achievement will unlock.

Halo 2: Collect all eight Halo toys.     (9) 

In total, there are 9 toys scattered across each of the 13 missions in the Campaign that must be collected for this achievement. These toy collectibles are extremely well-hidden and often time will require advanced tactics such as Sputnik grenade-jumps or out-of-the-map exploits in order to reach their locations. Needless to say, it will take a tremendous amount of exploring to locate these toys.

All in all, these toys are an awesome set of collectibles to hunt down. Take note however the toys will not appear while playing in Classic Mode, though using Classic Mode (as shown in the video guide below) may be necessary in reaching their location. Once all 9 toys have been collected, this achievement will unlock.

Legendary Anniversary 30
Halo 2: Complete every level of the game on Legendary difficulty.      (37) 


This achievement will unlock once all thirteen missions of the Halo 2 Campaign have been successfully completed on either a Solo Legendary playthrough or Cooperative Legendary playthrough. There are multiple methods in tackling the missions of the Campaign, but keep these general tips in mind when playing:

  • Utilize the Noob-Combo (Plasma Pistol/Battle Rifle) at all times when facing Elites; an overcharged Plasma Pistol shot will drain their shields, and a three-round burst to the skull will down the creatures easily
  • Utilize ground vehicles – Warthogs, Scorpions, and Ghosts – as frequently as possible; their firepower in missions such as Metropolis, Delta Halo, and The Great Journey will help clear out areas quickly and you can even drive past enemy encounters if the mission allows for it
  • When facing Hunters, get close enough so that they charge at you, allowing time to side step their attack; when the orange flesh on their back is exposed, shoot it, as this is their only weak spot
  • When squaring off against the Flood, keep a Shotgun or Energy Sword on hand; these are by far the best weapons to use against the parasite
  • Don’t neglect the basics of using cover; when your shields drop down, hide behind a wall or crouch behind an object before charging back out into battle
  • Try exploring the levels and finding alternate routes behind or around the enemies; this can help save time by skipping major firefights on levels such as Outskirts, Delta Halo, and Regret.

Overall, because seasoned Halo players will be familiar with both level design and enemy behavior, completing the entire Campaign on Legendary will be quite easy, though a very demanding task. Once all the missions in Halo 2 have been completed on the Legendary difficulty setting, this achievement will be yours.

Seconds 10
Halo 2: Complete a Halo 2 playlist.    (2) 

Please refer to "Connoisseur" for more information.

Connoisseur 20
Halo 2: Complete three Halo 2 playlists.    (2) 

In Halo: The Master Chief Collection, Campaign playlists make their debut as a means of experiencing a particular set missions that all share a common thread. Hand-crafted by the developer, some of these playlists are unique, such as all the Arbiter-realted missions or all Boss-related missions within the Campaign. There's also playlists for Easy Campaign, Normal Campaign, Heroic Campaign, Legendary Campaign, and LASO Campaign.

Since the LASO Campaign playlist must be completed for a separate achievement, all that is required is to complete a minimum of two other playlists for this achievement. In Halo 2: Anniversary, the shortest playlists - which also prove to be quite enjoyable - are the following:

  • Arbiter's Journey - The Heretic, The Arbiter, The Oracle, Sacred Icon, Quarantine Zone, Uprising, The Great Journey
  • Fan Favorites - Outskirts, Metropolis, Delta Halo, The Great Journey
  • Boss Fights - The Oracle, Regret, The Great Journey

Just pick and choose whichever three Campaign playlists you'd like to work on and once they have all been successfully completed, this achievement will be yours.

Six Pedals, Four Directions 10
Halo 2: Drive a Scorpion while playing as the Arbiter.    (7) 

This achievement can be obtained fairly early on during the “Quarantine Zone” mission. As soon as the introductory cutscene concludes, hop inside the Specter and be prepared to destroy the Enforcer and Sentinels that ambush your position. After dealing with them, head through the open doorway on the cliffside wall and descend the ramp that leads further into the underground structure.

If you stick to the right side of this room, continue driving your vehicle until you’re required to descend a small ramp that leads to a lower platform. Down here, tucked away in the back right corner, you will find a Flood-controlled Scorpion Tank. Simply exit your Specter and approach the Tank carefully in order to hijack the UNSC vehicle and thus, unlock the achievement.

Betcha can't stick it... 10
Halo 2: Stick a Plasma Grenade to a Stealth Elite on Outskirts.   (5) 

Before anything, make sure you load up the corresponding mission on the Easy difficulty. Additionally, go ahead and turn on the Assassins and Bandana skull in the Campaign lobby as this will permanently cloak all enemies in the mission and grant players infinite grenades. Start the mission and as soon as you gain control of the Chief, continue through the doorway and hallway, past the lone Grunt (be sure to kill him), and out into the large courtyard.

Once here, go ahead and switch to Classic Mode because cloaked enemies will be much, much easier to see in the older Halo 2 graphics. Now spot the building straight ahead of you and walk inside. On the bottom floor (or the top floor - it varies) there will always be an Elite roaming around. Although this Elite isn't technically a Stealth Elite, the Assassins skull confuses the game and will consider this enemy to be of the aforementioned rank. With that said, just switch over to your Plasma Grenade, stick the Elite and the achievement will unlock right away!

Cowardly Grunt 5
Halo 2: Listen to the Cowardly Grunt's woes.    (8) 

This Easter Egg can be found in the mission, Uprising.

The Cowardly Grunt is a unique dialogue enemy that can only be found in the aforementioned mission. After clearing out the first large room after the main cavern, you can find this Grunt cowering in fear next to two other dead Grunts. Upon approaching the Grunt, he’ll bark, "Please, no hurt! Me like Elites. Brutes stinky bad bad. Me stay here, make sure no Brutes come behind mighty Arbiter. Heh, heh... Eh?" Take note however that this line of dialogue will only work once all the Brutes in this room are dead. After the Grunt has finished talking, the achievement will unlock.

Siege of Ivory Tower 5
Halo 2: Listen to a hidden music cue in Halo 2.    (6) 

This Easter Egg can be found on the Multiplayer map, Ivory Tower.

The hidden music cue in this game is none other than Siege of Madrigal, a song that original Halo developer Bungie used in one of their previous video games. When standing in a specific spot on the aforementioned multiplayer map, you will be able to hear the faint melody to the song. With that said, go ahead and create a Custom Game on Ivory Tower. When the match begins, go to the ground level and stand by the metal door that is right behind the elevator. If you wait hear long enough, you will hear the song, though it is hard to hear. After a few seconds, the achievement will unlock.

THE Chips Dubbo? 5
Halo 2: Fight alongside the legendary Chips Dubbo and listen to his words.   (5) 

Private First Class Chips Dubbo is an Australian Marine that serves with the UNSC during the events of the Halo games. You can usually spot him within a firefight due to his think Australian accent and witty remarks. With that said, this achievement is actually quite simple as there doesn't seem to be a definitive location of where Chip Dubbo is. Rather, the achievement tends to unlock almost every single time upon running above the rooftops on Outskirts when going for the IWHBYD skull or Rex Sword Easter Egg. Overall, this achievement will more than likely come naturally to players during their time on the Campaign, so don't worry about needing to do anything special in order to find Chips or trigger a special line of dialogue.

Rex Sword 10
Halo 2: Grab the energy sword on the level Outskirts.    (8) 

This Easter Egg can be found in the mission, Outskirts.

This hidden sword can be obtained right from the start of the aforementioned mission. Once you gain control of the Master Chief, exit the area of the Pelican crash site and head into the hallway. Kill the Grunt that is walking up the ramp and then turn around, jump on the light fixture above of the door, and perform a crouch jump onto the roof of the hallway. From here, you will need to jump to the raised rooftop to the left via another crouch jump.

Once you fall down unto the destroyed highway, perform a grenade jump to reach the roof of the buildings. Once on the rooftops, head towards the left and you will notice a ruined building with a dilapidated roof. Jump inside this building and you can see an Energy Sword sticking out of the ground, much like Excalibur. Once you retrieve the Energy Sword, the achievement will unlock.

10 Minutes Too Early 5
Halo 2: In The Oracle, find the holo-drone before the Heretic Leader activates it.    (5) 

Holo-Drones are small Covenant devices that provide holographic duplicate decoys of important personnel. Physically, they resemble inactive Plasma grenades in size and shape. On the aforementioned mission then, the Heretic Leader uses two Holo-Drones in the final fight against the Arbiter. Earlier in this mission however, you can find a single Holo-Drone.

As soon as the mission begins, walk through the initial room and past the corridor where Flood are fighting beneath the glass floor. In the next room, stick to the right walkway and jump on the closest pillar, then on the pillar closest to the glass tube. From here, destroy the tube with your weapon and then crouch jump onto the center structure. Once here, turn around and crouch jump onto the ledge above your current position. From up here, you will see two holes in the corner of the wall. Get as close to the right hole as possible and perform a grenade jump. Once inside this cubbyhole, you will find the Holo-Drone floating in the air and the achievement will unlock.

HI BEN 5
Halo 2: Oh, hi!    (7) 

This Easter Egg can be found in the mission, Regret.

On the aforementioned mission, you will find the words “HI BEN” written in black text on the ceiling of a hidden room. This hidden egg was originally dedicated to Benjamin Burnley of Breaking Benjamin, whose song was used in the original version of the game.

To begin, precede through the mission until your reach the platform where a pair of Hunters are dropped off. You may opt to kill all the Covenant units here, though it’s not necessary. In this area, continue to the side of the platform that is facing the small, isolated temple. Jump onto the ledge of the platform and you should see a broken bridge to your right and a balcony right in front of you. While standing on the ledge, throw a grenade at your feet and perform a grenade jump in order to be launched towards the balcony window. From here, simply follow the corridor to the right and enter the dark room at the end. You will need to shine your flashlight on the ceiling in the far left corner of the room in order to spot the hidden egg. As soon as you see the message, the achievement will unlock.

For an alternative strategy in reaching this Easter Egg, be sure to follow the video guide below.

E E E 5
Halo 2: View both signs in the level Metropolis.    (8) 

This Easter Egg can be found in the mission, Metropolis.

After emerging from the large, winding highway tunnel and fighting past a large unit of Covenant forces (including a Wraith) inside a gassy valley, you will eventually return to the city streets of New Mombasa. Here, your main objective tasks you with progressing towards the building on the other end of the street to regroup with your Marines.

Before doing that however, take a sharp left the side-street that branches off the main street. Here, continue moving to the forward down the street and in the far left corner, you will find a terminal-like console that flickers two different messages. Simply look at these signs in Remastered Mode for about ten seconds and the achievement is yours.

GOOOAAAAALLLL!10
Halo 2: Shoot the soccer ball in the level Metropolis.    (11) 

This Easter Egg can be found in the mission, Metropolis.

The soccer ball in the aforementioned mission is hidden high above the rooftops of the skyscrapers in the city-street area after emerging from the highway tunnel and battling the Covenant within a grassy valley. There are about six distinct ways in getting to the soccer ball’s location, though the two methods detailed below are the best ways in finding the hidden ball.

The first method involves retrieving a Banshee (details can be found below in the next achievement). After picking up the Scarab Gun with the Banshee, head along the highway. Once you pass the amphitheater, you’ll spot a ruined building with a massive hole in its side. At the bottom of this blown out hole, you will see the giant Soccer Ball tucked away in a dark corner.

The second method doesn’t involve a Banshee, though the Sputnik skull must be activated. After the firefight in the large grass valley, you will exit into the city streets. On the other side of the street, there is a large building with a piece of broken glass sticking out of a large crack. Stand on the support edge of this building and perform a grenade jump into the large crack. From here, you will need to carefully navigate up the building by jumping on the broken support beams. Once you get to the last support beam, walk onto the roof of the building and into the large dark room on your left. Here, you will find the soccer ball. Once you’ve found the hidden ball, simply shoot it with whatever weapon you currently have equipped and the achievement will unlock.

Make sure to refer below to "Scarab Lord" where you will find a video guide detailing the methods involved in reaching the hidden soccer ball.

Needs More Whammy Bar 5
Halo 2: Complete the level Regret with the Prophet Birthday Skull activated.   (5) 

The Prophet Birthday Skull is a new skull modifier introduced in Halo 2: Anniversary which causes each and every smack on the Prophet of Regret’s face to be accompanied by Steve Vai guitar riffs and flamboyant lightening bolts.

As such, all you have to do is activate this skull in the Campaign lobby and then load up the aforementioned mission on any difficulty setting. Once you reach Regret’s temple towards the end of the mission, continue as you normally would in defeating the Prophet of Regret and the achievement will unlock after he has been defeated.

Like Peanut Butter and Chocolate 10
Halo 2: Complete a level in co-op on Heroic or Legendary with the Masterblaster Skull active.     (5) 

The Masterblaster Skull is a new skull modifier introduced in Halo 2: Anniversary that only works when playing cooperatively. Its effects are as follows: One player has recharging overshields but can only melee attack enemies while the other player has no shields but is granted infinite ammo; these roles will switch periodically after a set amount of kills.

With that said, grab a cooperative partner, activate this skull in the Campaign lobby and choose any of the missions within the Campaign. Cairo Station is probably the best mission to attempt this achievement given its short length. As a note, teamwork is key when working on this achievement so make sure to communicate with your Co-Op partner as you progress through the entire mission. The player who has overshields should charge into firefights and melee the enemies while the player who has infinite ammo picks off Grunts and Elites from afar with their Battle Rifle. Make sure to pay attention to when the roles swap so that the offensive player does not get ambushed in battle while their shields are deactivated. Once the mission is complete, the achievement will unlock after the concluding cutscene.

Starved For Shields 10
Halo 2: Complete a level with only the Streaking Skull active on Heroic or Legendary.     (3) 

The Streaking Skull is a new skull modifier introduced in Halo 2: Anniversary that causes player’s shields to constantly decay. Fortunately, your shields will recharge slowly after each and every kill, thus making it slightly similar to the original Black Eye Skull.

Activate this skull in the Campaign lobby and choose whichever mission you’d like. As a note, Armory is without a doubt the best mission to attempt this achievement since all there is to do here is complete the "basic training" and follow Johnson to the station's bridge. Alternatively, Outskirts works too (if you're playing in Co-Op - Armory isn't available in Co-Op) since you can skip the first three firefights by exploiting the rooftop running while the second portion of the level offers a Warthog, meaning you can simply drive past all enemy encounters. Just keep in mind that no other skulls may be activated when working on this achievement.

Also, as a general suggestion, be sure to utilize mid-ranged weapons such as the Battle Rifle if you employ the second mission's strategy and need to get some kills to recharge your shields. The Battle Rifle's firepower can score kills from afar, meaning you won’t have to confront enemies in close-quarters combat. Once the mission you have chosen has been completed, the achievement will unlock after the concluding cutscene.

Commuter 10
Halo 2: Complete Metropolis without entering a vehicle on Heroic or Legendary.     (2) 

As soon as this mission begins, you will immediately be made aware that this is predominantly a vehicle-emphasized mission given the outdoor landscape and number of Covenant vehicles along the bridge towards the main objective. Don’t let this intimidate you, for completing the mission on foot, though tedious, is entirely doable, especially if you are playing cooperatively with another player.

Right from the start then, ignore the Warthog and the Scorpion Tank. You’ll need to make your way down the entirety of the bridge killing Covenant troops and vehicles with whatever weapons you have at your disposal. Once you reach the tunnel at the end of the bridge, continue your way towards the main objective, past the blockade and through the detour tunnel. After emerging from the tunnel, continue past this open valley until your reach the city streets. All that is required at this point is to destroy a number of Wraiths and rendezvous with the Marines stationed in the building ahead. Once you pass through the building and board the Covenant Scarab, the mission will end shortly after once the controls to the Scarab have been destroyed.

As mentioned earlier, this achievement is better suited with cooperative partners as they can utilize the firepower of both UNSC and Covenant vehicles to kill enemy troops while you stay back on foot. All in all, if you managed to avoid using any vehicles throughout this mission, the achievement will unlock after the concluding cutscene.

NOTE: The utilization of the following skulls may help tremendously for this achievement: Scarab, Bandana, Envy, and Sputnik.

He Never Gets Me Anything 10
Halo 2: Complete Delta Halo without entering a vehicle on Heroic or Legendary.     (5) 

As you progress past the initial firefights of this mission, you will immediately be made aware that this is predominantly a vehicle-emphasized mission given the outdoor landscape, Scorpion Tank reinforcement, and the number of Covenant vehicles along the path towards the main objective. Don’t let this intimidate you, for completing the mission on foot, though tedious, is entirely doable, especially if you are playing cooperatively with another player.

With that said, once you have activated the bridge to cross the gorge, ignore the Scorpion Tank that is delivered and make your way past the Covenant Wraith and Ghosts into the winding corridors of the structure ahead. Throughout this section of the mission, there will be a number of Ghosts harassing your movements, though you should have no problem picking off the Elite drivers with the Battle Rifle or Plasma Grenades. Overall, after a number of firefights along the path to the main objective, including a large battle against Hunters and Sniper Jackals towards the end of the mission, simply descend the ramp that leads to a small tempe-like structure. Once inside, defeat the Elite Honor Guards and the mission will end as you approach the hologram in the center of the room.

As mentioned earlier, this achievement is better suited with cooperative partners as they can utilize the firepower of both UNSC and Covenant vehicles to kill enemy troops while you stay back on foot. All in all, if you managed to avoid using any vehicles throughout this mission, the achievement will unlock after the concluding cutscene.

NOTE: The utilization of the following skulls may help tremendously for this achievement: Scarab, Bandana, Envy, and Sputnik.

Scarab Lord 20
Halo 2: Acquire the Scarab Gun.    (19) 

This Easter Egg can be found in the mission, Metropolis.

The Scarab Gun is a hidden egg in the aforementioned mission that looks like a standard Plasma Rifle, but holds the firepower of a Scarab’s focus cannon. This weapon has unlimited ammo, a bottomless clip, and never overheats. Take note that it is only accessible in this mission and will not carry over to any other mission in the game. With that said, be sure to follow the step-by-step guidelines below in order to acquire the Scarab Gun. It’s a very complicated procedure, so playing on a lower difficulty setting with another player may ease the tension.

  • At the start of the mission, kill all of your allies
  • Proceed through the mission normally
  • When you get to the end of the bridge, hijack a Covenant Ghost and kill all enemy ground vehicles and troops
  • At this point, there should be a Banshee flying overhead
  • Lure the Banshee into the tunnel by driving the Ghost in reverse
  • Fire around the Banshee to keep his interest, but do not damage the Banshee
  • About halfway through the tunnel, Marines will appear in a Warthog; kill them and all other Covenant forces that get in your way
  • Continue luring the Banshee through the tunnel
  • Once you reach the blockade, exit the Ghost and lure the Banshee through the blockade by firing around it with your weapon
  • In the detour hallway, lure the Banshee to the left path that leads to the next section of the mission
  • At this point, the Banshee will get stuck due to the narrowness of the tunnel so carefully shoot off its wings
  • As the Banshee attempts to move further into the tunnel, be prepared to board it
  • When the "Loading ..." message appears on the screen, hijack the Banshee
    • The Banshee will disappear if you do not board the Banshee when the prompt reads "Loading...done"
  • Piloting the Banshee, proceed out of the tunnel and fly towards the suspension bridges in the distance
  • At the very top of the bridge, the Scarab Gun will be hovering on above an orange cone

This process is very complicated despite the simplicities of the steps detailed above. This is because the Banshee has a tendency to lose interest and flee the tunnel and at other times, the Banshee will get stuck towards the final stretch inside the detour tunnel. For a visual aid in obtaining this achievement, be sure to follow the video guide below.

Silent but Deadly 10
Halo 2: Kill 7 opponents from behind in a row without being spotted.   (4) 

Contrary to the achievement's description here, killing seven enemies does not necessarily have to be from behind. Rather, so long as you "stealthily" kill seven enemies in a row without your position being revealed, you'll be fine. There's two distinct strategies in obtaining this achievement, so use whichever works best for you.

On one hand, you can load up Cairo Station on the Legendary difficulty setting and activate the Scarab skull in the Campaign lobby. When you reach the first hanger via the second floor, you will see some enemies on the ground level shooting at the Marines on the catwalk. Use whichever weapon you have at your disposal - like the Battle Rifle - and kill this first wave of Covenant. Then, be ready to blast the dropship's "tube" where the next set of enemies begin to spawn from. If you are playing in Remastered Mode, the corpses will get stuck in the geometry of the "tube" and remain there. At this point, the third wave of Covenant will begin to spawn, but their movement will be blocked due to the dead bodies. If you shoot your weapon at "tube" at this point, it will count as a stealth kill since the enemies are not technically loaded into the mission yet. The achievement should unlock here without issue, though it's not always guaranteed.

An alternate strategy is to load up Gravemind on Normal (or Easy). Here, you do not need to activate any skulls. When the mission begins, continue normally throughout the corridors of High Charity until you take an energy lift down to the prison cells. When you arrive, Cortana will inform you about two groups of Marines that need your help in breaking free from the Covenant's cells. After clearing out the middle floor and rescuing the first group of Marines, head down the bottom-most floor and approach the doorway that leads to the second room of prison cells. At this point, you should receive a checkpoint before entering the room. Make sure to wait around until this checkpoint registers. Once it does, enter the room and melee the Brute patrolling the center of the room; he will always have his back to you. After killing the Brute, go ahead and smack the sleeping Grunts in the room as well. Quickly revert your checkpoint once you kill the Grunts and then repeat this same exact process to get your final two-three kills and the achievement should unlock without any issues.

Demon 10
Halo 2: Complete any campaign level without dying on Normal or harder.    (2) 

Cairo Station is without a doubt one of the best missions to attempt this achievement given the fact that it’s the shortest mission within the entire Campaign. You’ll also come to realize that given the nature of the station’s design structure, it’s also the most confined mission in terms of navigable space for firefights. This provides for an excellent tactic in flushing out rooms with grenades and using close-to-medium-ranged weapons to kill the Covenant.

Make sure to utilize the Noob-Combo (Battle Rifle/Plasma Pistol) and grenades as often as possible when taking on groups of Covenant enemies inside the station. Since most of the corridors and hanger bays you fight within aren’t that large compared to other firefights within the Campaign, a single grenade can usually flush out most of the weaker Covenant units while the Noob-Combo is effective at medium range in killing Elites.

Another strategy is to tackle the aforementioned mission cooperatively with another player. This method is great since your partner can go forth and clear out all the enemies, while you stay back and avoid any and all crossfire between your partner and the Covenant. If you are successful in completing the mission without dying whatsoever, the achievement will unlock after the concluding cutscene.

Go Ape Shiv 5
Halo 2: Kill an enraged, berserk Brute using melee.    (3) 

Brutes are known to descend into a highly aggressive, berserk killing-rage when all of their pack members have been killed. As such, they will drop their weapons and begin to charge towards you with no remorse. Their strength and aggression while berserk makes them as dangers as Hunters, especially since Brutes will charge at vehicles and hijack them.

After you kill all but one Brute in a pack, be prepared to engage in close-quarters combat with the berserk Brute. The missions “Gravemind” and “Uprising” present the most opportune moments when attempting this achievement. As a general tip, it’s always best to jump over the Brute as they charge towards you. If you’re quick enough, you can then turn around and melee their back/side, thus killing them in one or two hits. Either way, after you melee kill a berserk Brute, this achievement will unlock.

Back At It 5
Halo 2: Play a game of Halo 2 Anniversary on the 9th of any month.    (2) 

As a means of celebrating the launch date of the original Halo 2, this achievement simply tasks you to play the aforementioned game on the 9th of any month. This can be done by playing any of the ten Campaign missions and even messing around in a Custom Game with friends or hopping online and playing a match on a Halo 2 map. Overall, this achievement is pretty straightforward and can be obtained with minimal effort of your part.

Back for More 30
Halo 2: Complete the LASO campaign playlist.    (66) 

As with any of the playlists dedicated to the Halo 2 Campaign, the LASO Campaign playlist will task players in completing all nine missions on the Legendary difficulty with all skulls on. Take note however that the developer has selected a preset number of skulls for this Campaign, so all the skull modifiers aren’t technically activated. With that said, this achievement can be earned in either Solo or Co-Op play.

What’s more, it’s important to remember that only scoring skulls will be activated. These generally reward players with higher score multipliers and bonuses to base enemy values (for Par Score achievements). Non-scoring skulls on the other hand are sometimes neutral, such as Grunt Birthday Party, or considered “cheat skulls” such as Bandana and Scarab Gun. Below, you can get a glimpse of all the skulls that will be activated in the Halo 2 LASO Campaign playlist.

  • Anger - Enemies fire their weapons faster and more frequently.
  • Assassins - All enemies in the game are permanently cloaked.
  • Black Eye - Your shields only recharge when you melee enemies. Bash your way to better health!
  • Blind - HUD and weapon do not display onscreen.
  • Catch – Enemies throw and drop more grenades.
  • Famine - Weapons dropped by AI have half the ammo they normally would. You might want to pack an extra magazine.
  • Ghost - AI no longer flinch from attacks.
  • Grunt Birthday Party - Grunt headshots lead to glorious celebrations.
  • Iron - Death carries a heavy price. Dying in co-op resets you at your last saved checkpoint. Dying solo restarts the level.
  • IWHBYD - Rare combat dialogue becomes more common.
  • Mythic - Enemies have increased health.
  • Sputnik - Mass of objects is decreased, making them more easily displaced.
  • That’s Just…Wrong - Increases enemy awareness of player.
  • Thunderstorm - Upgrades the rank of most enemies.

As you can see, Halo 2’s LASO Campaign playlist has the most skulls activated, some of which are unique and will prove to be much more difficult than the other Campaigns. As a few general tips, keep the following suggestions in mind when tackling this achievement.

First, take combat slowly and try picking off enemies from afar with medium-ranged weapons like the Battle Rifle or Covenant Carbine. Even though enemies will be permanently cloaked, they will be throwing grenades and firing their weapons more frequently. This essentially gives away their position on the battlefield. Also, your HUD and weapon will not appear on screen, so it may take some time in getting used to the “blinded” touch.

Moreover, since deaths will revert your progress to the mission-start, it’s highly recommended to attempt this achievement in Co-Op play. Lastly, enemies are going to be even more agile and aware of your presence in firefights but don’t be hesitant in engaging in close-quarters combat, especially since the effects of Black Eye will greatly effect your shields.

Overall, with enough persistence and skill, the Halo 2 LASO Campaign playlist can be done, though it will take a considerable amount of dedicated time. Once the thirteenth mission has been completed through this playlist, the achievement will unlock.

He's Running a Marathon... 5
Halo 2: Spot the developer in the opening cutscene of Gravemind on Legendary in Classic Mode.     (6) 

This Easter Egg can be found in the mission, Gravemind.

Take note that you must start this mission from the beginning on Legendary and have Classic Mode activated when watching the cutscenes. If these prerequisites are not in place, the hidden egg will not appear. After the initial opening cutscene between the Arbiter, Gravemind, and Master Chief concludes, the camera will pan to High Charity, where a mass of Grunts and Jackals are swarming the entrance to the inner council chamber. Here, you will notice a 2D figure of a man in boxers dancing within the Covenant crowd. Simply watch the cutscene through and the achievement will unlock naturally.

Tighten Up The Graphics 10
Halo 2: Complete every level of Halo 2 having seen it in both classic and remastered mode.    (5) 

For this achievement, all that it necessary in order to experience the game in both modes is to switch between Classic Mode and Remastered Mode once or twice for all thirteen missions within the Campaign. To do this, simple tap the view button on the controller and this will toggle between the two modes with nearly no delay whatsoever.

You may end up finding yourself naturally switching between modes as you explore the vast landscapes and structures of each mission. Thus this achievement may come naturally without even thinking about it. Overall, just keep in mind that you'll need to toggle the visuals once or twice per mission in order to make progress towards this achievement. Once all thirteen missions have been seen in both Classic Mode and Remastered Mode, this achievement will finally unlock.

The Return of Megg 20
Halo 2: She's not picking up.    (5) 

This Easter Egg can be found in the mission, Cairo Station.

Unlike the Megg Easter Egg in Halo: Combat Evolved, this hidden egg is actually a special line of dialogue that is announced over the PA system once you reach the hanger bay that houses the Covenant bomb. In order to trigger the unique line of dialogue, the following constraints must be met:

  • Play Cairo Station on Solo Legendary
  • The Thunderstorm skull must be activated (Envy & Scarab skulls may be activated as well to help)
  • You must reach the bomb room without ever getting shot

Although this sounds almost impossible at first, it’s actually quite simple for experienced Halo players, especially since the Scarab skull is allowed. First off, you’ll want to understand that the Thunderstorm skull does nothing more than upgrade all Covenant enemies to their highest rank. This mean the Grunts and Elites in this mission will be promoted to Spec Op and Ultra units. As with any Legendary playthrough of a mission, be sure to utilize the Noob-Combo (Battle Rifle/Plasma Pistol) during this mission. A charged Plasma Pistol shot will drain an Elite’s shields immediately and a three-round burst to the head with the Battle Rifle will kill them with ease.

As for reaching the end of the mission without getting shot, you have the option to revert your save to the last checkpoint if you do take damage. This will not void the achievement and makes this task much easier. Once you reach the final bomb room, if all the prerequisites are in place, the following line of dialogue can be heard, though faintly, over the PA system, “Megg, please report to the red courtesy phone. Megg, to the red courtesy phone.” The achievement will unlock right after the announcement has concluded.

Before anything, make sure to turn on "Timing HUD" in the Campaign Lobby before starting a mission. In order to beat the Par Time on all nine missions with Halo 3's Campaign, you will want to take three things into account.

First, play on the Easy difficulty setting so that enemies aren't as dangerous. Secondly, don't bother turning on any skull modifiers in the lobby. Lastly, utilizing the various speed running tactics as shown in Halo 3's speed running achievement will help immensely in skipping certain firefights and finishing each mission in a considerably less amount of time as normal. With these tips in mind, you should have no problem completing each mission under Par Time.

You can use the checklist below for a reference on each mission’s Par Time:

  • Sierra 117 - 15:00 minutes
  • Crow’s Nest – 20:00 minutes
  • Tvaso Highway – 20:00 minutes
  • The Storm – 15:00 minutes
  • Floodgate – 15:00 minutes
  • The Ark – 20:00 minutes
  • The Covenant – 20:00 minutes
  • Cortana – 15:00 minutes
  • Halo – 20:00 minutes

Overall, just remember to play on the lowest difficulty setting and try rushing past as many firefights when possible. Once you beat the Par Time for all nine missions, this achievement will unlock.

Better With Age 20
Halo 3: Beat the par score on every Halo 3 level.    (3) 

Before anything, make sure to turn on "Scoring HUD" in the Campaign Lobby before starting a mission. In order to achieve the Par Score on all ten missions with Halo 3's Campaign, you will want to take three things into account.

First, manually activate the Cowbell, Famine, Fog, Grunt Birthday Party, Thunderstorm, and Tough Luck skulls in the lobby and set the difficulty to Heroic. If the mission is exclusively a Flood-oriented mission, such as Floodgate and Cortana, go ahead and activate the Catch skull. Since Flood do not throw grenades, this essentially becomes a free multiplier.

Unfortunately, Par Scores cannot be obtained in Co-Op play, so just stick with a solo playthrough of each mission here. Secondly, you will want to try completing the mission as quickly as possible (finishing under Par Time will give a x3 multiplier to your final score) while still killing everything on the battlefield via headshots and multikills; do not skip firefights or leave anyone alive. Lastly, if you do happen to run over Par Time, try picking up the pace as the time multiplier will begin to reduce significantly!

You can use the checklist below for a reference on each mission’s Par Score:

  • Sierra 117 - 13,000
  • Crow’s Nest – 19,000
  • Tvaso Highway – 21,000
  • The Storm – 15,000
  • Floodgate – 25,000
  • The Ark – 25,000
  • The Covenant – 25,000
  • Cortana – 17,000
  • Halo – 24,000

Once you beat the Par Score for all nine missions, this achievement will unlock.

Once inside, activate the terminal as you normally would and wait on the final page until the screen turns red. After this happens, the terminal would usually bring you further into the database for more information. This time, a direct message from Mendicant Bias, a Forerunner AI, will appear, stating the following: "You don't know the contortions I had to go through to follow you here, Reclaimer. I know what you're here for. What position do I take? Will I follow one betrayal with another?" After a few seconds of viewing this message, the achievement will finally unlock.

This achievement will unlock once all nine missions of the Halo 3 Campaign have been successfully completed on either a Solo Legendary playthrough or Cooperative Legendary playthrough. There are multiple methods in tackling the missions of the Campaign, but keep these general tips in mind when playing:

  • Utilize the Noob-Combo (Plasma Pistol/Battle Rifle) at all times when facing Brutes; an overcharged Plasma Pistol shot will drain their Power Armor, and a quick three-burst shot headshot will down the enemies easily
  • Utilize ground vehicles – Warthogs, Scorpions, and Ghosts – as frequently as possible; their firepower in missions such as Tsavo Highway, The Covenent, and The Ark will help clear out areas quickly and you can even drive past enemy encounters if the mission allows for it
  • When facing Hunters, get close enough so that they charge at you, allowing time to side step their attack; when the orange flesh on their back is exposed, shoot it, as this is their only weak spot
  • When squaring off against the Flood, keep a Shotgun on hand; it’s the best weapon to use against the parasite
  • Don’t neglect the basics of using cover; when your shields drop down, hide behind a wall or crouch behind an object before charging back out into battle
  • Try exploring the levels and finding alternate routes behind or around the enemies; this can help save time by skipping major firefights on levels such as Sierra 117, The Storm, The Covenant, and The Ark

Overall, because seasoned Halo players will be familiar with both level design and enemy behavior, completing the entire Campaign on Legendary will be quite easy. If a text-based walkthrough is necessary, be sure to visit THIS GUIDE for further assistance with this achievement. Once all the missions in Halo 3 have been completed on the Legendary difficulty setting, this achievement will be yours.

Begins with a Single Step 10
Halo 3: On Tsavo Highway, complete the level without entering a vehicle.   (7) 

As you start this mission, you will immediately be made aware that this is predominantly a vehicle-emphasized mission, though you will have no problem completing it on foot, especially if you are playing with one or two other players. With that said, avoid grabbing the Warthogs in the hanger bay at the start of this mission and simply wait until the blast door is opened by the Marine. From here, you’ll have to traverse the landscape on foot and pass through a number of valleys containing Sniper Jackals and Brutes of varying ranks. It is highly recommended to grab a Beam Rifle and Fuel Cannon during these initial firefights.

After clearing out the first major blockade and the swarm of Drones, continue down the main road on foot into the next valley filled with Brutes and Grunts. Here, you’ll need to kill the initial wave of enemies before a few waves of appear via Phantoms. There’s plenty of equipment and weaponry around this valley so the following waves of enemies – containing Wraiths and Choppers - shouldn’t be too rough.

As mentioned earlier, this achievement is better suited with cooperative partners as they can utilize the firepower of Covenant vehicles to kill enemy troops while you stay back on foot. All in all, after this long-winded battle, continue on through the mission until your required to climb up to a bridge and proceed down the highway. Be ready to fend off against several more waves of Brutes and Sniper Jackals. Once all the enemies at the end of the highway have been dealt with, destroy the Shield Generator to finish the mission. If you managed to avoid using any vehicles throughout this mission, the achievement will unlock after the concluding cutscene.

Who Needs Them? 10
Halo 3: On The Ark, complete the level without entering a vehicle on Legendary.     (19) 

As you progress past the initial firefights of this mission, you will immediately be made aware that this is predominantly a vehicle-emphasized mission given the open outdoor landscape and number of enemy Wraiths along the path to the main objective. Don’t let this intimidate you, for completing the mission on foot, though tedious, is entirely doable, especially if you are playing cooperatively with one or two other players.

With that said, avoid grabbing any Covenant Choppers, Ghosts, or Wraiths when battling the enemy in the several valleys within the canyon. In addition to this, you will also have to deliberately ignore any Mongoose or Scorpion vehicles that are dropped off via Pelican. As mentioned earlier, this achievement is better suited with cooperative partners as they can utilize the firepower of both Covenant and UNSC vehicles to kill enemy troops while you stay back on foot.

Once you enter the map room after several exhausting firefights against Brutes, Wraiths, and even a Scarab, the necessity of vehicles for the rest of the mission diminishes. Simply fight your way past the remaining Covenant units inside the structure and make your way towards the objective. When the final room inside the Cartographer has been cleared, approach the Pelican to finish the mission. If you managed to avoid using any vehicles throughout this mission, the achievement will unlock after the concluding cutscene.

Phantom Hunter 10
Halo 3: Destroy 3 total Phantoms on The Covenant.    (5) 

During the midpoint of this mission, where you are required to pilot a Hornet in order to proceed to the second objective, you will notice a Covenant Phantom (enemy Phantoms are purple, friendly Phantoms are green) deploying an Anti-Air Wraith on a plateau in the distance. After the Phantom pulls back, focus your attention on the Banshees and Wraith. Once these units have been destroyed, close in on the Covenant dropship as it retreats to the third tower. Again, focus your attention on the Banshees in this area before finally unloading the Hornet’s rockets and machine gun into the Phantom’s hull.

Since this is the only Covenant Phantom that appears in this mission, this achievement must be earned over separate playthroughs or by reloading your checkpoint. If you are loading this mission from the Campaign lobby, make sure to pick Rally Point Alpha. This will place you at the moment where you are required to pilot the Hornet. Once a total of three Phantoms have been destroyed on this mission, the achievement will finally unlock.

Annual 10
Halo 3: Complete Halo on 4-player Legendary co-op, with Iron Skull, and everyone in Ghosts.     (127) 

s a pesky reoccurring achievement, most of you should be familiar with the requirements in getting this done. First, you must activate the Iron skull and begin the ninth mission of the game, Halo, from its beginning; you cannot start at Rally Point Alpha.

With the Iron skull activated, any death will revert all players back to their latest checkpoint. As for the locations of the Ghosts, after fighting 343 Guilty Spark inside the control room, you will find a set of four Ghosts parked underneath the walkway outside the control room’s main entrance. From here, each player must grab a Ghost and proceed to complete the mission as you regularly would.

For additional tips on this achievement, refer below:

  • All four players should communicate via headsets; communication is vital in order to prevent deaths throughout the mission
  • When piloting the Ghosts towards Forward Unto Dawn, try to remain at a steady pace with the rest of the group, while never slowing down too much; if you take too long, the panels will give way and you will die
  • Don’t worry about stopping to kill the Flood; piloting the Ghost right by them is recommended and almost necessary

With clear communication and steadfast dedication, you and your team should have no problem pulling this off. The first half of the mission is the only difficult part, given the massive fight up towards the control room against the Flood. Once 343 Guilty Spark has been defeated, the Ghost run should be pretty simple. As soon as the first player makes the jump towards Forward Unto Dawn, the ending cutscene will ensue and the achievement will unlock for all four players in the game.

Dirge of Madrigal 5
Halo 3: Trigger the hidden music cue in Halo 3.    (5) 

This Easter Egg can be found in the mission, The Covenant.

The hidden music cue in this game is none other than Dirge of Madrigal, a song that original Halo developer Bungie used in one of their previous video games. When standing in a specific spot on the aforementioned mission, you will be able to hear the faint melody to the song. Be sure to follow the guidelines listed below, since it’s a slightly complicated process to trigger the hidden music cue.

  • After defeating the two Scarabs, ignore the waypoint and fly a Hornet toward the left of the Citadel (the building that Truth is located in)
  • Carefully land the Hornet on the structure and run along this ledge
  • Eventually, the ledge will turn into a 45-degree slope, but at the top of the slope, the song can be heard
  • It will begin to play almost immediately after you reach the top of the slope

Overall, once you have successfully reached the required spot, Dirge of Madrigal will be triggered and the achievement will unlock.

Primate 5
Halo 3: Find your first missing links.    (10) 

Please refer below to "Haplorrhini" for more information.

Haplorrhini 5
Halo 3: Find a lonely missing link.    (12) 

This Easter Egg can be found in the mission, Sierra 117.

On the first mission of the Campaign, there are unique hidden Cavemen that can be located in three distinct locations within the African jungle. The first of these Caveman can be located high above the tree line that runs parallel to the river where Johnson's Pelican is shot down. Utilizing a Battle Rifle to zoom in and scan the treetops will unlock "Missing Link" once you spot the Caveman.

The second location in the jungle ahead of this area. After clearing out the Covenant forces around the pump station, enter the jungle ahead and stick to the left. Continue jumping on the rocks along the path and you will eventually reach a large plateau where a family of Cavemen can be found. This family of Cavemen will unlock the Primate achievement.

The final Caveman can be located on a cliff just outside the boarders of the level in the area where Sergeant Johnson is being held prisoner. In order to reach this location, you will need to perform a complicated glitch to exit the mission’s boarders, however the Cavemen is still visible via a Sniper Rifle while standing on the bridge where Hocus picks you up. Whether you decide to reach this Caveman’s location via the glitch or simply by zooming in on his location, the "Haplorrhini" achievement will unlock once you spot him.

Can't Keep Him Down 5
Halo 3: Fight alongside and listen to The Man. The Legend. Chips Dubbo.   (2) 

Private First Class Chips Dubbo is an Australian Marine that serves with the UNSC during the events of the Halo games. You can usually spot him within a firefight due to his think Australian accent and witty remarks. With that said, this achievement is actually quite simple as there doesn't seem to be a definitive location of where Chip Dubbo is. Rather, the achievement tends to unlock almost every single time upon running through the Crow's Nest mission. Overall, this achievement will more than likely come naturally to players during their time on the Campaign, so don't worry about needing to do anything special in order to find Chips or trigger a special line of dialogue.

Flipyap 5
Halo 3: Listen to the tale of a young Grunt named Flipyap.    (10) 

This Easter Egg can be found on nearly any mission of the game, so long as the prerequisites are in place.

Flipyap is a Covenant Grunt that is often times mentioned in a long line of dialogue by a Grunt when another Grunt nearby has been killed. In order to trigger this line of dialogue however, the IWHBYD skull must be activated when playing a Campaign mission.

Generally, there is no one spot to trigger this unique dialogue, so just tackle missions at your own pace on any difficulty and keep Grunts alive at times to increase the chances they recount the humorous tale of Flipyap. Once the story of Flipyap has begun, the achievement will unlock.

Heading to his Destiny 5
Halo 3: Destined for greatness.    (6) 

This Easter Egg can be found in the mission, Halo.

On the aforementioned mission, proceed to the area where the seventh terminal is located inside a cave on the cliffside entrance. Opposite the room of the terminal, there is a secret area where this Egg is located. Simply stand on the ledge facing the dark corridor opposite the terminals and perform a grenade jump to reach a horizontal beam inside the chasm. From here, you can perform another jump (crouch or grenade) into the small lit-alcove on the left. Once inside this alcove, turn your flashlight o. In the far left corner, you will spot Jason Jones, the co-founder of Bungie Studios, in gym shorts and unlock the achievement as well.

Sounds Familiar 5
Halo 3: This stuff is your history!     (8) 

This Easter Egg can be found on the Multiplayer map, High Grounds.

In order to unlock this achievement, you will need to hear a hidden song while playing on the aforementioned Multiplayer map. In order to hear this song, simply head into the base on the north end of the map and head inside the main computer room. Here, you will notice a large radio tucked underneath one of the computer stations. If you wait around long enough near this radio, the static will fade and Halo: Combat Evolved’s score “Under Cover of Night” will begin to play. Once the song begins to play, the achievement will unlock shortly after.

Milk Carton 5
Halo 3: Find the poster of the missing man.    (10) 

This Easter Egg can be found in the mission, The Storm.

Towards the end of this mission, as you enter the final outdoor area that leads to the Anit-Aircraft Battery, make your way through the Covenant forces until you reach the Prophet of Truth’s hologram console. From here, turn to your left and you will see a narrow corridor with small storage rooms on either side. The poster of the missing man can be found lying on the floor in one of these storage units on the left. When you find it, simply zoom in on the poster and the achievement will unlock.

Cool Story Bro 5
Halo 3: Listen to the story of the Final Grunt.    (6) 

This Easter Egg can be found in the mission, Halo.

This Grunt can be found towards the very end of this mission on the edge of a cliff right before you drive down the ramp that leads into the hanger of Forward Unto Dawn. As soon as you ascend the platforms, drive to the right, near the large white rock arch and steer your vehicle slowly around this narrow pathway. At the end of the pathway, a lonely Grunt can be found. When approached, the Grunt will mock the Master Chief and then beg for mercy soon after. The achievement will unlock after the Grunt finishes his line of dialogue.

Take note that if you are playing alone, the Arbiter will always fire the Warthog’s chaingun at the Grunt, thus voiding the Grunt’s speech and the achievement. Also, take note that listening to the Grunt’s tale makes it impossible to complete the rest of the mission. This is due to the reast that the platforms will have broken apart, leaving no possible route to reach the Forward Unto Dawn.

Third Time's A Charm 5
Halo 3: Play a game of Halo 3 on the 25th of any month.     (1) 

As a means of celebrating the launch date of the original Halo 3, this achievement simply tasks you to play the aforementioned game on the 25th of any month. This can be done by playing any of the nine Campaign missions and even messing around in a Custom Game with friends or hopping online and playing a match on a Halo 3 map. Overall, this achievement is pretty straightforward and can be obtained with minimal effort of your part.

Mind the Gap 10
Halo 3: 4 vehicles, 1 gap on Legendary using Cowbell, Catch, Thunderstorm, Mythic, and Tough Luck.     (40) 

This mission-specific achievement is obtained in the following mission: Tvaso Highway. Additionally, while this can technically be done in a Solo playthrough of the mission, it is highly recommended to work on this achievement in four-player Co-Op play. Once you have three other Co-Op partners and are in the Campaign Lobby, go ahead and turn on the aforementioned skulls.

After the lobby has been set up, start the mission. Once all the players present gain control of their characters, break off into two groups and grab both Warthogs in the basement hanger. Then, start rolling out into the valleys outside. Along the way, you can find three more overturned Warthogs, two of which the passengers should grab as their own. As a note, you don't necessarily need to fight against the Covenant within these valleys, though it might be necessary to jump out of the Warthogs for a few minutes and lay waste to the Jackal Snipers, Turrets, and Brute Captains/Chieftains so that the Warthogs stay intact.

Once all four players have their own Warthog, continue through the mission until you reach the area that houses two Choppers, half a dozen Brutes, and an energy barrier that blocks vehicular movement through the tunneled highway. In this area, everyone should get out of their Warthogs and work together in clearing out the Covenant threat. Once that's done, head through the energy barrier on foot, destroy the energy source and get ready to lay waste on the Drones that spawn inside the tunnel. After they have been eliminated, head backwards to the main valley and check the small buildings. One of them has a Gravity Lift which is necessary for this achievement.

With the Gravity Lift in possession, all four players should now hop back into their Warthogs and head through the tunnel. Continue to drive down the highway and accelerate over the first small jump in the road. Just ahead, you should see a few concrete barriers blocking passage to the rest of the highway. At this point, everyone should line their Warthogs up in a straight line and the first player should drop the Gravity Lift in front of the barriers. This player should then quickly get back in the Warthog and now all four players should proceed to drive forwards through the Gravity Lift. If angled correctly, the lift will shoot all the players up in the air as they drive over it and launch they'll be launched forward over the gap in the highway. Once the fourth player has safely landed on the highway, the achievement will unlock for all four players in the game.

A Preference for Pain 30
Halo 3: Complete the Halo 3 LASO Campaign playlist.    (36) 

As with any of the playlists dedicated to the Halo 3 Campaign, the LASO Campaign playlist will task players in completing all nine missions on the Legendary difficulty with all skulls on. Take note however that the developer has selected a preset number of skulls for this Campaign, so all the skull modifiers aren’t technically activated. With that said, this achievement can be earned in either Solo or Co-Op play.

What’s more, it’s important to remember that only scoring skulls will be activated. These generally reward players with higher score multipliers and bonuses to base enemy values (for Par Score achievements). Non-scoring skulls on the other hand are sometimes neutral, such as Grunt Birthday Party, or considered “cheat skulls” such as Bandana and Scarab Gun. Below, you can get a glimpse of all the skulls that will be activated in the Halo 3 LASO Campaign playlist.

  • Black Eye - Your shields only recharge when you melee enemies. Bash your way to better health!
  • Blind - HUD and weapon do not display onscreen.
  • Catch - Enemies throw and drop more grenades.
  • Cowbell - Acceleration from explosions is increased.
  • Famine - Weapons dropped by AI have half the ammo they normally would. You might want to pack an extra magazine.
  • Fog - The motion tracker is disabled. You'll miss those eyes in the back of your head.
  • Grunt Birthday Party – Grunt headshots lead to glorious celebrations.
  • Iron - Death carries a heavy price. Dying in co-op resets you at your last saved checkpoint. Dying solo restarts the level.
  • IWHBYD - Rare combat dialogue becomes more common.
  • Mythic - Enemies have increased health.
  • Thunderstorm – Upgrades the rank of most enemies.
  • Tilt – Enemy resistances and weaknesses are increased.
  • Tough Luck – Enemies always go berserk, always dive out of the way, never flee.

As a few general tips, keep the following suggestions in mind when tackling this achievement. First, take combat slowly and try picking off enemies from afar with short controlled bursts of medium-ranged weapons like the Battle Rifle or Covenant Carbine. Since your HUD and weapon will not appear on screen, it may take some time in getting used to the “blinded” touch. Also, choose your shots wisely and always aim for vulnerable weak spots since ammo is scarce on the battlefield, and enemies will have increased health and resistances. Second, since deaths will revert your progress to the mission-start, it’s highly recommended to attempt this achievement in Co-Op play. Lastly, enemies are going to be agile in combat, diving away from your shots and throwing a lot of grenades, so don’t forget the basics of cover, and when necessary, close-quarters combat, especially since shields will only recharge upon melee attacks.

For an in-depth, text-based guide in completing Halo: 3's LASO playlist (either by yourself or through Co-Op play), please refer to THIS GUIDE. A huge thanks goes to Mythic Tyrant for making such a guide available to the Halo community.

Overall, with enough persistence and skill, the Halo 3 LASO Campaign playlist shouldn’t be too hard if you follow Tyrant's walkthrough. Just take the missions slowly and once the ninth mission has been completed through this playlist, the achievement will unlock.

Afficiando 20
Halo 3: Complete three Halo 3 playlists.    (2) 

In Halo: The Master Chief Collection, Campaign playlists make their debut as a means of experiencing a particular set missions that all share a common thread. Hand-crafted by the developer, some of these playlists are unique, such as all the vehicle-realted missions or all ambush-related missions within the Campaign. There's also playlists for Easy Campaign, Normal Campaign, Heroic Campaign, Legendary Campaign, and LASO Campaign.

Since the LASO Campaign playlist must be completed for a separate achievement, all that is required is to complete a minimum of two other playlists for this achievement. In Halo 3, the shortest playlists - which also prove to be quite enjoyable - are the following:

  • Wheels, Wheels, and More Wheels - Tsavo Highway, The Ark, Halo
  • Mixin' It Up - Sierra 117, The Storm, Cortana
  • Heavy Anticipation - Crow's Nest, Floodgate, The Covenant

Overall, simply pick and choose whichever three Campaign playlists you'd like to work on and once they have all been successfully completed, this achievement will be yours.

Witch Doctor 20
Halo 3: Find and claim all Skulls in Halo 3.     (7) 

In total, there are 13 skulls scattered across each of the 9 missions in the Campaign that must be collected for this achievement. These skull collectibles are extremely well-hidden and come in the appearance of an actual human skull. At times, you will find that some are only obtainable for reaching obscure locations via grenade jumps and other advanced tactics. Needless to say, it will take a tremendous amount of exploring to locate these skulls.

These skulls are a unique collectible in that they act as significant gameplay modifiers. When activated via the Campaign Lobby Menu, skulls will alter the way the Campaign is played by either removing your HUD, causing explosions to double their blast radius, or even disabling the recharge ability of your shields unless you melee an enemy. With that said, these skulls are an awesome set of collectibles to hunt down. Once all 13 skulls have been collected, this achievement will unlock.

No Stone Unturned 20
Halo 3: Activate all Halo 3 Terminals.     (4) 

In total, there are 8 terminals spread across four specific missions within the Campaign that must be activated for this achievement. These terminal stations are well-hidden so it will take a keen eye and some exploration in order to track them down. You’ll know when you’ve found a terminal by the spotting a large cylindrical console-like structure that opens once you approach it.

When the terminal opens, it will reveal a large holographic sphere of blue and yellow light. Simply approach the holographic panel and hold the action button to activate it. From here, simply skim through the pages until you reach the final message. After sitting on this final page for a few seconds, the screen will turn red and the terminal will redirect you to another database full of information, where you will have to skim another set of two or three pages.

Take note that you do not necessarily need to read all second database of notes in the terminal because progress towards this achievement registers as soon as the terminal redirects you after the red screen. It is highly recommended to spend the time in reading the notes of each page though since they will provide subtle backstory to the Halo Universe. Once all 8 terminals have been activated, this achievement will unlock.

Halo 4: Beat the par time on all Halo 4 levels.    (3) 

Before anything, make sure to turn on "Timing HUD" in the Campaign Lobby before starting a mission. In order to beat the Par Time on all eight missions with Halo 4's Campaign, you will want to take three things into account.

First, play on the Easy difficulty setting so that enemies aren't as dangerous. Secondly, don't bother turning on any skull modifiers in the lobby. Lastly, utilizing the various speed running tactics as shown in Halo 4's speed running achievement will help immensely in skipping certain firefights and finishing each mission in a considerably less amount of time as normal. With these tips in mind, you should have no problem completing each mission under Par Time.

You can use the checklist below for a reference on each mission’s Par Time:

  • Dawn - 15:00 minutes
  • Requiem – 15:00 minutes
  • Forerunner – 20:00 minutes
  • Infinity – 25:00 minutes
  • Reclaimer – 20:00 minutes
  • Shutdown – 20:00 minutes
  • Composer – 20:00 minutes
  • Midnight – 25:00 minutes

Overall, just remember to play on the lowest difficulty setting and try rushing past as many firefights when possible. Once you beat the Par Time for all eight missions, this achievement will unlock.

You Had it Coming 20
Halo 4: Beat the par score on every Halo 4 level.    (5) 

Before anything, make sure to turn on "Scoring HUD" in the Campaign Lobby before starting a mission. In order to achieve the Par Score on all eight missions with Halo 4's Campaign, you will want to take three things into account.

First, manually activate the Cowbell and Grunt Birthday Party skulls in the lobby and set the difficulty to Legendary. You will probably already notice that these two skulls do not have beneficial multipliers, though don't let that confuse you. The former skull will make explosions a bit deadlier when combatting Covenant and Promethean enemies, while the latter skull will make Grunt enemies drop extra Plasma Grenades if killed via a headshot.

There isn't a necessity in turning on any of the scoring skulls during this playthrough since each of the missions in Halo 4 will grant you more than enough points even without any extra multipliers. Remember though, Par Scores cannot be obtained in Co-Op play, so just stick with a solo playthrough of each mission. This will also net help net progress towards the Lone Wolf Legend achievement.

Secondly, you will want to try completing the mission as quickly as possible (finishing under Par Time will give a x3 multiplier to your final score) while still killing everything on the battlefield via headshots and multikills; do not skip firefights or leave anyone alive. Lastly, if you do happen to run over Par Time, try picking up the pace as the time multiplier will begin to reduce significantly!

You can use the checklist below for a reference on each mission’s Par Score:

  • Dawn - 25,000
  • Requiem – 22,000
  • Forerunner – 22,000
  • Infinity – 25,000
  • Reclaimer – 25,000
  • Shutdown – 25,000
  • Composer – 25,000
  • Midnight – 25,000

Once you beat the Par Score for all eight missions, this achievement will unlock.

Terminus 20
Halo 4: Activate all Halo 4 Terminals.     (4) 

In total, there are 7 terminals spread across each of the 8 missions within the Campaign that must be activated for this achievement. These terminal stations are well-hidden and usually off the main path of your objective, so it will take a keen eye and some exploration in order to track them down. You’ll know when you’ve found a terminal by the spotting a dim yellow ball of light on a Forerunner terminal console. Simply approach the console and hold the action button to activate it.

Take note that you do not necessarily need to watch the entire terminal because progress towards this achievement registers as soon as it’s activated. It is highly recommended to spend the two to three minutes in observing each terminal though. Once activated, they will provide crucial backstory on the Forerunner. Once all 7 terminals have been activated, this achievement will unlock.

This achievement will unlock once all eight missions of the Halo 4 Campaign have been successfully completed on a Solo Legendary playthrough. There are multiple methods in tackling the missions of the Campaign, but keep these general tips in mind when playing:

  • Utilize the Noob-Combo (Plasma Pistol/Battle Rifle or DMR) at all times when facing Elites and Knights; an overcharged Plasma Pistol shot will drain their shields, and a quick three-shot burst to the head will down the enemies easily
  • Utilize vehicles – Warthogs, Scorpions, Ghosts, and Banshees – as frequently as possible; their firepower in mission such as Forerunner, Reclaimer, and Shutdown will help clear out areas quickly and you can even drive past enemy encounters if the mission allows for it
  • When facing Hunters, get close enough so that they charge at you, allowing time to side step their attack; when the orange flesh on their back is exposed, shoot it, as this is their only weak spot
  • When squaring off against the Prometheans, always kill Watchers first; they act as a Knight’s defense unit
  • Try avoiding close-quarters combat with Knights; their arm blades will tear you to pieces in one swipe at times
  • Don’t neglect the basics of using cover; when your shields drop down, hide behind a wall or crouch behind an object before charging back out into battle
  • Try exploring the levels and finding alternate routes behind or around the enemies; this can help save time by skipping major firefights on levels such as Forerunner, Reclaimer and Composer

Overall, because seasoned Halo players will be familiar with both level design and enemy behavior, completing the entire Campaign on Legendary will be quite easy. If a text-based walkthrough is necessary, be sure to visit THIS GUIDE for further assistance with this achievement. Once all the missions in Halo 4 have been completed Solo, on the Legendary difficulty setting, this achievement will be yours.

This is my Rifle, This is my Gun 10
Halo 4: Carry a UNSC weapon all the way through Forerunner on Heroic or Legendary.     (7) 

When this mission begins, you will have the Assault Rifle and Magnum automatically equipped by default. This achievement requires you to carry at least one of these weapons to the end of the mission, without ever dropping it for a replacement. Take note that if you run out of ammo, you’ll have to make due with a secondary weapon.

Overall, it’s highly recommended on working towards this achievement on the Heroic difficulty while keeping the Magnum throughout the course of this mission. It’s an extremely effective weapon in picking off Crawlers and Watchers from afar and even pulling off quick headshots on Knights if they are weak. You can ditch the Assault Rifle at any time for something a little more accurate; this includes Forerunner weaponry such as the Light Rifle or Scattershot.

If for whatever reason you accidently drop the weapon of choice for this achievement, you can always revert your save to the last checkpoint. Once the mission’s final cutscene has concluded, this achievement will unlock.

Bros to the Close 10
Halo 4: Complete Infinity without one preventable Marine death on Heroic or Legendary.     (5) 

This achievement is best obtained when playing on the Heroic difficulty with three cooperative partners. In addition to this, you can opt to start the mission at Rally Point Bravo, as doing so will place you in the mission just after the cutscene where Lasky and Palmer are introduced.

At this time, you will need to complete the next objective without allowing any Marine allies to die. After emerging from the structure after the cutscene, two Marines will fight by your side. You will need to kill a small wave of Promethean enemies and advance up a winding path where another swarm of Crawlers and Knights are stationed. As a general note, approach these first two firefights offensively. Don’t be hesitant in rushing into the line of fire and dispatching the enemies with close-quarter means. Once the Prometheans here are dead, double check that both Marines are still alive.

After climbing down the winding path, you will reach another squadron of four Marines that are under attack by Prometheans on the hillside ahead. Be sure to utilize a ranged weapon such as the Battle Rifle or Light Rifle in picking off the Crawlers, Watchers, and Knights that are ambushing the Marines. Once this initial wave of enemies has been cleared, climb the hillside and insert Cortana’s AI chip into the nearby console when she gives you the command. At this point, you will now have to fend off the hillside from three or so waves of Prometheans forces. Make sure to utilize the mounted machine guns, Railgun, grenades, and any other weapons at your disposal during this massive firefight.

Once Cortana has successfully opened the door and the enemies have been killed, the achievement will unlock so long as all six Marines are still alive. If for whatever reason the achievement hasn’t unlocked or a Marine has died at any point during this entire section of the mission, you can always revert your save to the last checkpoint and try again. Remember, doing this with three cooperative players will prove to be much easier than trying alone.

Explore the Floor 10
Halo 4: Trick or force a Hunter to fall to its demise on Shutdown.    (13) 

By this point in the game, you should be familiar with Hunters in both their appearance and their general combative behavior. During the mission, Shutdown, you will eventually reach a large Forerunner chasm that has several platforms filled with enemies. On the other side of the chasm, there is an energy lift that must be taken in order to reach the next portion of the mission. On this final platform, a duo of Hunters will greet you.

Once you reach this area, kill one of the Hunters. With the second Hunter alive, you will want to trick him into charging off the side of the platform. This can be done by standing at the edge and allowing the Hunter to charge straight at you. Right before he hits you jump up and utilize your jet pack to hover in the air right over him. If timed correctly, the Hunter will have little time to stop the momentum of his attack and run right off the platform, thus unlocking the achievement.

Give Him the Stick 10
Halo 4: Take out both Hunters using only the Sticky Detonator on Composer.   (2) 

Towards the beginning of this mission, you will come across a Marine who is trampled by some Jackals. This Marine drops a Sticky Detonator to make sure to pick up since you’ll need it during another firefight.

After making your way through Ivanoff Station, you will eventually pass through a corridor where a scientist explains the situation ahead in the laboratory: a pair of Hunters are attacking the remaining scientists. At this point, you’ll want to enter the lab and face off against the Hunters by only utilizing the Sticky Detonator.

Keep in mind that the Sticky Detonator only has five shots, however if you are playing on a lower difficulty setting, the Hunters can be killed with one or two shots each so you’ll have plenty of ammo. In addition, the small cubicle-like room in the back right corner of the lab has extra ammunition if necessary. After both Hunters here have been killed with the Sticky Detonator’s rounds, the achievement will unlock.

Chief, Smash! 10
Halo 4: Kill 3 Crawlers in one hit with the Gravity Hammer on Midnight.   (3) 

Once you reach the mid-way point of this final mission, you will find yourself inside a Forerunner armory. You’ll notice that there are plenty of powerful weapons to choose from here, but for this achievement, you’ll want to grab the Gravity Hammer.

After exiting the armory, you’ll soon come to a segment where Cortana’s AI chip must be inserted into a terminal. As Cortana hacks the Forerunner network, you will need to defend your position from countless waves of Crawlers. At this point, allow the Crawlers to swarm the central platform where the terminal is located. When they are all grouped together, you should have no problem in bringing the Gravity Hammer down and killing at least three of these pesky Crawlers with a single swing, thus unlocking the achievement. This may take a few tries depending on how spread out they are, but there are plenty of Crawlers during this firefight for multiple attempts at this achievement.

You're No Chips 5
Halo 4: What do Marines know about sticks?    (7) 

This Easter Egg can be found in the mission, Composer.

About halfway through the aforementioned mission, the Master Chief will be required to clear out a room filled with scientists that are under attack by a pair of Covenant Hunters. After this fight, head through the "objective" door that leads to the main elevator within Ivanoff Station. Inside, there will be a lengthy cutscene where Master Chief and Dr. Tillson descend into the facility where the Composer is being held.

Once you regain control of the Master Chief after the cutscene, head through the winding corridor on your right and you will then exit into the Composer's large chamber. Ignore the objective at hand and travel to the far side of the chamber where you can see an observation room with the words "IVANOFF STATION" written on the paneling. On the platform outside this observation room, there will be a group of two Marines testing out one of the new Mantis mech. Stay close to the Marines here and after they finish their witty exchange of dialogue, the achievement will unlock a few seconds later.

A Long Time Ago 5
Halo 4: Play a game of Halo 4 on the 6th of any month.     (1) 

As a means of celebrating the launch date of the original Halo 4, this achievement simply tasks you to play the aforementioned game on the 6th of any month. This can be done by playing any of the eight Campaign missions and even messing around in a Custom Game with friends or hopping online and playing a match on a Halo 4 map. Overall, this achievement is pretty straightforward and can be obtained with minimal effort of your part.

Mortardom 10
Halo 4: On Reclaimer, use a Wraith to kill at least four enemy Wraiths on Heroic or Legendary.     (5) 

The first order of business here before attempting this achievement is to successfully hijack an enemy Wraith. The best way in doing so would be to pick off a Wraith’s turret gunner from afar with a ranged weapon, and then shooting an overcharged Plasma Pistol shot to immobilize the vehicle. With the vehicle immobilized, you will now want to quickly jump into the turret gunner seat. This will force the driver out of the cockpit, so get ready to mow down the pilot with the turret and the Wraith is now yours.

With this in mind, load up Rally Point Bravo on the mission in question and proceed through the canyon and through the Forerunner structure until you take a portal that links you up with your Marines. It's worth noting that during the canyon fight, you should grab a Plasma Pistol. Once you are grouped up with your Marines, hop inside one of the Scorpion tanks and kill your allies and the Covenant Ghosts in the area.

Now you can safely pick off the gunner of the Wraith straight ahead, Plasma Pistol overcharge the vehicle, and grab it for yourself. There a total of six or seven enemy Wraiths in this area, so killing four shouldn't be a problem. Once four enemy Wraiths have been destroyed via your own, this achievement will unlock.

Digging up the Past 5
Halo 4: Access the Master Chief's records on Dawn.    (2) 

Towards the start of the first mission, this achievement can be obtained fairly early on before any big firefights or events even occur. After gaining control of the Master Chief, simply walk forward through the corridor ahead.

Instead of passing into the next room, turn to the left and descend the staircase. Down here, you will spot a terminal of the other side of the room, so approach the console and activate it to read the Master Chief’s records, thus unlocking the achievement. Take note that this terminal does not necessarily count towards the "Terminus" achievement.

Naked Tyrant 30
Halo 4: Complete the Halo 4 LASO Campaign playlist.    (36) 

As with any of the playlists dedicated to the Halo 4 Campaign, the LASO Campaign playlist will task players in completing all eight missions on the Legendary difficulty with all skulls on. Take note however that the developer has selected a preset number of skulls for this Campaign, so all the skull modifiers aren’t technically activated. With that said, this achievement can be earned in either Solo or Co-Op play.

What’s more, it’s important to remember that only scoring skulls will be activated. These generally reward players with higher score multipliers and bonuses to base enemy values (for Par Score achievements). Non-scoring skulls on the other hand are sometimes neutral, such as Grunt Birthday Party, or considered “cheat skulls” such as Bandana and Scarab Gun. Below, you can get a glimpse of all the skulls that will be activated in the Halo 4 LASO Campaign playlist.

  • Black Eye - Your shields only recharge when you melee enemies. Bash your way to better health!
  • Blind - HUD and weapon do not display onscreen.
  • Catch - Enemies throw and drop more grenades.
  • Cowbell - Acceleration from explosions is increased.
  • Famine - Weapons dropped by AI have half the ammo they normally would. You might want to pack an extra magazine.
  • Fog - The motion tracker is disabled. You'll miss those eyes in the back of your head.
  • Grunt Birthday Party – Grunt headshots lead to glorious celebrations.
  • Iron - Death carries a heavy price. Dying in co-op resets you at your last saved checkpoint. Dying solo restarts the level.
  • IWHBYD - Rare combat dialogue becomes more common.
  • Mythic - Enemies have increased health.
  • Thunderstorm – Upgrades the rank of most enemies.
  • Tilt – Enemy resistances and weaknesses are increased.
  • Tough Luck – Enemies always go berserk, always dive out of the way, never flee.

As a few general tips, keep the following suggestions in mind when tackling this achievement.

First, take combat slowly and try picking off enemies from afar with short controlled bursts of medium-ranged weapons like the Battle Rifle or Light Rifle. Since your HUD and weapon will not appear on screen, it may take some time in getting used to the “blinded” touch. Also, choose your shots wisely and always aim for vulnerable weak spots since ammo is scarce on the battlefield, and enemies will have increased health and resistances.

Moreover, since deaths will revert your progress to the mission-start, it’s highly recommended to attempt this achievement in Co-Op play with two or three other players since the Iron skull will revert deaths to the most recent checkpoint. Lastly, enemies are going to be agile in combat, diving away from your shots and throwing a lot of grenades, so don’t forget the basics of cover, especially since your shields will only recharge upon melee attacks.

For an in-depth, text-based guide in completing Halo: 3's LASO playlist (either by yourself or through Co-Op play), please refer to THIS GUIDE. A huge thanks goes to Mythic Tyrant for making such a guide available to the Halo community.

Overall, with enough persistence and skill, the Halo 4 LASO Campaign playlist shouldn’t be too hard. Just take the missions slowly and once the eighth mission has been completed through this playlist, the achievement will unlock.

Devotee 20
Halo 4: Complete three Halo 4 playlists.    (1) 

In Halo: The Master Chief Collection, Campaign playlists make their debut as a means of experiencing a particular set missions that all share a common thread. Hand-crafted by the developer, some of these playlists are unique, such as all the Covenant-realted missions or all CQC-related missions within the Campaign. There's also playlists for Easy Campaign, Normal Campaign, Heroic Campaign, Legendary Campaign, and LASO Campaign.

Since the LASO Campaign playlist must be completed for a separate achievement, all that is required is to complete a minimum of two other playlists for this achievement. In Halo 4, the shortest playlists - which also prove to be quite enjoyable - are the following:

  • The Covenant Threat - Dawn, Requiem, Composer
  • Canyon Combat - Forerunner, Reclaimer, Composer
  • Tight Corridors - Dawn, Shutdown, Midnight

Simply choose whichever three Campaign playlists you'd like to work on and once they have all been successfully completed, this achievement will be yours.

Bite The Hand10
Kill a 343 developer in matchmaking or someone who has this achievement.    (15) 

According to Halo Waypoint’s Community Calendar, members of 343 Industries will be on Xbox Live and in Halo’s matchmaking on November 17th, from 6:00-8:00pm PST (Pacific Standard Time).

What this means is that on the aforementioned date, players will be matched up with 343 developers and once they have killed a developer, they will unlock this achievement. From there, anyone who kills that particular player will also unlock the achievement and so on. Like any viral achievement, it will take a while before a large portion of the online community has this achievement. If you stick with the Multiplayer long enough, you’ll come across an enemy player who has already unlocked it and thus, once you kill them, the achievement will be yours.

Goat Roped30
Halo CE: Halo CE: Complete all Halo: CE Legendary campaign missions in under 3 hours.    (47) 

As one of the four Legendary speed running achievements, this achievement will prove to be one of the most difficult tasks within the entire collection. It's worth noting that you may want to grab a Co-Op partner when working on this achievement for two reasons. One, the extra firepower will help put down enemies a little quicker. Secondly, one player can usually act as a decent distraction while the second player attempts to push on and run by as many enemies as possible in an attempt to grab the next checkpoint.

This essentially means that you may want to replay individual missions dozens of times in order to perfect your runs and learn new tactics in skipping various firefights. Unfortunately, a text-based guide would be too tedious in explaining every single mission within the game, so please refer to THIS LINK for an in-depth look at completing Halo: CE's Legendary Campaign in under three hours. A huge thanks goes out to Naked Eli for providing the video content.

As confirmed by Sun100, this achievement does not need to be attempted in one continuous run. Rather, the game will track your best time on each mission completed on the Legendary difficulty setting and add them up for a grand total. When a new "Personal Record" is set for that mission, it will override the previous tracked time. This essentially means that you can tackle a mission multiple times in an attempt to perfect your speed run.

NOTE: By following the speed running tactics provided in the video link above, you will almost certainly obtain the Par Time achievement for each of the Campaign's ten missions. This means that if you have yet to grab the Par Time achievements on the Easy or Normal difficulty setting, they can be stacked on the Legendary difficulty setting while working on this achievement.
 

Animal Habitat5
Halo 2: Spot the hippo on the walls of Headlong in classic multiplayer.    (4) 

Go ahead and load a Custom Game on Headlong and make your way over to the yellow paneled building. On the bottom floor, along the yellow walls, there is graffiti that says, “Part of the Solution” and a small drawings of a hippo. All you have to do is zoom in on the drawing of the hippo and after a few seconds, the achievement will unlock.

Sid Graffiti5
Halo 2: Spot the Sid graffiti on the walls of Coagulation in classic multiplayer.    (5) 

Load up a Custom Game on Coagulation and head towards the main cave where the Overshield/Active Camouflage spawns. Once inside, walk towards the arched frame that overlooks a small pond. On the left side of this arch, you will see a faint message of “Not Sid Was Here Not” etched into the rocks. The writing may be a little hard to read, so try looking at it from different angles until the achievement unlocks.

Why So Serious5
Halo 2: View the smiling face in the classic multiplayer map Coagulation.    (3) 

To begin, load up a Custom Game on Coagulation and head towards Red Base. This hidden face can be found on one of the three large rocks located directly in front of Red Base. If you walk in the middle of these rocks and look towards the top half of the rock closest to the cliff in the distance, you should see the outline of a smiling face. The outline of the face may be a little hard to distinguish, so try looking at it from different angles until the achievement unlocks.

Why Am I Here?5
Halo 2: View this hidden message on the classic Beaver Creek map.    (4) 

Load up a Custom Game on Beaver Creek and head towards the perch where the Sniper Rifle spawns. From here, continue past the weapon and jump onto the cliffside ledge. Turn to the left slightly and melee the large rocks here so that they fall off the ledge. Right behind the rocks, you will find faint, etched writing with a signature that reads “Not Sid.” The writing may be a little hard to read, so try looking at it from different angles until the achievement unlocks.

Grand Theft Halo10
Halo 2A MP: In one match, steal a total of 5 occupied vehicles from opponents.    (7) 

Hijacking vehicles is as simple as approaching an enemy-occupied vehicle and boarding it by pressing the action button when prompted on-screen. This can easily be boosted in a Custom Game with another player or a second controller on Bloodline. Once the match starts, both players should grab their Ghosts at their home base and meet in the middle of the map. Here, just trade off hijacks back and forth until the achievement unlocks.

Tour of Duty10
Halo 2A MP: Complete a game in every one of the 6 updated Anniversary MP maps.    (2) 

The six remastered Halo 2 maps are Bloodline, Stonetown, Zenith, Shrine, Lockdown, and Warlord. In order to knock this achievement out quickly, load up a Custom Game by yourself on each of the new maps. When the match begins, pause the game and select "End Game." This will give you an automatic win, so just repeat this method for the other five maps and the achievement will be yours in no time.

Double Down10
Halo 2A MP: In Anniversary multiplayer, receive 2 or more Double Kill medals.    (1) 

In Multiplayer, the Double Kill medal is awarded to players who kill two opponents within four seconds of each other. As such, you will want to focus your attention on playing offensively when working on this achievement, utilizing close-quarters combat and weaponry to kill enemies quickly.

As a suggestion, this is best done when boosted with two other players in a Custom Game on a small map such as Warlord. All three players should meet up in a central location on the map. Then one player should kill the other two players quickly to receive their Double Kill medal and go on to repeat the process a second time for the achievement.

Warden10
Halo 2A MP: In Anniversary matchmaking, stop the killing spree of another player.   (4) 

In order to unlock this achievement, you must obtain a Killjoy medal in any Halo 2: Anniversary Multiplayer map. This medal is awarded to players for killing an enemy player who is on a Killing Spree of five kills or higher. As such, this will most likely come naturally as you play various different FFA and Team-based game types. Please take note that this cannot be boosted in a Custom Game.

Blown Out of the Sky10
Halo 2A MP: Blow up the Banshee or Hornet in flight while piloted, with the Rocket Launcher.    (4) 

This achievement is best done in a Custom Game on Bloodline with at least one other player. There is one Hornet positioned just outside both bases at each end of the map. As for obtaining a Rocket Launcher, simply change the player traits in the Custom Game lobby so that all players spawn with Rocket Launchers.

When the match begins, one player should pilot their Hornet and fly towards the middle of the map. Here, the second player can use their Rocket Launcher to lock onto the aerial vehicle and destroy it with a single rocket. The achievement will unlock immediately after the vehicle has been destroyed, though make sure to return the favor for your partner.

Decorated Warrior10
Halo 2A MP: Get awarded at least 10 different medals in one non-team multiplayer game.    (4) 

Medals are awarded to players who undertake a specific action or perform a certain stylized kill on an enemy. As such, medals can range from capturing an enemy’s flag, to earning five kills without dying and even beating down enemy players. Below, you can find ten of the most common medals that will come naturally to experienced players in nearly any standard Slayer gametype:

  • Comback Kill
  • Headcase
  • Reload This
  • Double Kill
  • Killjoy
  • Killing Spree
  • Beat Down
  • Grenade Stick
  • Sniper Kill
  • Hijacker
  • Splatter

If vehicles are not present on the map, two common substitutions for the Hijacker and Splatter medals are the Close Call and Kill from the Grave medals. Also, take note that while the description stated that this achievement must be done in a FFA match, there have been reports of players unlocking the achievement in team-based games. Either way, once ten different medals in a single match have been earned, this achievement will be yours.

Ninja Redux10
Halo 2A MP: Kill 5 people with melee from behind in Anniversary matchmaking.   (2) 

In order to unlock this achievement, you must obtain the Beatdown medal at least five times in any Multiplayer map and gametype by melee attacking an enemy from behind. Unlike a frontal assault, a melee attack to the back will kill enemies in one hit. If you're having trouble with it, just make sure to get the drop on unaware enemy players or perform a "ninja jump/beatdown" and this achievement will be yours in no time. Take note that this achievement is cumulative, meaning you do not have to get five assassin medals in a single match.

Flaming Ninja Anniversary10
Halo 2A MP: Kill an opponent that has the Ninja Redux achievement in Anniversary matchmaking.   (1) 

Fortunately, the achievement’s description here is quite self-explanatory though you will come to realize that there is no true way of knowing when an enemy has the aforementioned achievement. With that said, simply continue to play the Multiplayer portion of the game and you will eventually unlock this achievement since the Ninja Redux achievement is not too hard to obtain for most players.

Legend Slayer10
Halo 2A MP: Kill an opponent that has the Legendary Anniversary achievement.    (7) 

In regards to the Legendary Anniversary achievement, this is awarded to players who have completed the Halo 2 Campaign on the Legendary difficulty. It's hard to gauge whether this achievement will be common among the online community, but since Halo 2’s Campaign is at the forefront of this collection, it should be quite common in due time. Thus, continue to spend time in the Multiplayer and this achievement will be yours in no time. Alternatively, you can also boost this in a Custom Game if you have a friend who has obtained the Legend Anniversary achievement.

Monopolized30
Halo 2: Complete all Halo 2 Legendary campaign missions in under 3 hours.    (37) 

As one of the four Legendary speed running achievements, this achievement will prove to be one of the most difficult tasks within the entire collection. It's worth noting that you may want to grab a Co-Op partner when working on this achievement for two reasons. One, the extra firepower will help put down enemies a little quicker. Secondly, one player can usually act as a decent distraction while the second player attempts to push on and run by as many enemies as possible in an attempt to grab the next checkpoint. Just remember that when playing Halo 2 on Co-Op Legendary, the death of one player will revert your progress to the most recent checkpoint.

This essentially means that you may want to replay individual missions dozens of times in order to perfect your runs and learn new tactics in skipping various firefights. Unfortunately, a text-based guide would be too tedious in explaining every single mission within the game, so please refer to THIS LINK for an in-depth look at completing Halo 2's Legendary Campaign in under three hours. A huge thanks goes out to Naked Eli for providing the video content.

As confirmed by Sun100, this achievement does not need to be attempted in one continuous run. Rather, the game will track your best time on each mission completed on the Legendary difficulty setting and add them up for a grand total. When a new "Personal Record" is set for that mission, it will override the previous tracked time. This essentially means that you can tackle a mission multiple times in an attempt to perfect your speed run.

NOTE: By following the speed running tactics provided in the video above, you will almost certainly obtain the Par Time achievement for each of the Campaign's thirteen missions. This means that if you have yet to grab the Par Time achievements on the Easy or Normal difficulty setting, they can be stacked on the Legendary difficulty setting while working on this achievement.

Hippo Hero5
Halo 3: Who DARED to discard this brave animal?    (7) 

Although this hidden Easter Egg is difficult to explain through text, go ahead and start up a Forge Session on Foundry. As soon as the session begins, enter Editor Mode and travel to the middle of the map. Staring towards the back wall of the warehouse, pan the camera down slowly. You should see a couple piles of trash on the floor, though you’ll want to approach the small trash pile on the right. If you get close enough to the floor in Editor Mode while scanning this trash pile, you will see a stuffed hippo lying in the waste, staring right at you. After looking at the hippo for a few seconds, the achievement will unlock.

Man on the Moon5
Halo 3: He's watching you.    (4) 

Load up a Custom Game on Standoff and change the player trait settings so that all players begin with Sniper Rifles. Once the match begins, position yourself anywhere on the edge of the map near the cliffside base so that the moon is in full view. Now use your Sniper Rifle’s scope to zoom in on the bottom right corner of the moon. Here, you will notice a faint outline of a smiling man, Chris Carney, who was originally a Bungie employee. After focusing on the man's face for a few seconds, the achievement will unlock.

Elder Signs10
Halo 3: View 2 different sigils on Valhalla.    (3) 

Similar to the seasonal change in the “No Swimming” sign on Halo 2’s Multiplayer map Zanzibar, you will find a unique message written in white lettering on the Forerunner wall (behind the machine gun turret) of Valhalla depending on the specific date. The following dates are when different messages can be found on the side of the base:

  • January 1st (New Year's Day): Make Love Not War
  • April 22nd (Earth Day): A skull with a recycling sign
  • May 5th (Cinco De Mayo): Toady Was Live!
  • July 4th (Independence Day): BBQ at Bob's
  • October 31st (Halloween): A grave stone that has the initials "R.I.P."
  • November 11th (Veteran's Day): Kilroy Was Here
  • December 25th (Christmas): A Christmas light with an “X” marked through it

Approach these sigils on two different dates and zoom in to view the new messages presented. Take note that this achievement is best done in a Custom Game when the specific dates arrive. The achievement will unlock once two different sigils have been viewed.

Devastating30
Halo 3: Complete all Halo 3 Legendary campaign missions in under 3 hours.    (36) 

As one of the four Legendary speed running achievements, this achievement will prove to be one of the most difficult tasks within the entire collection. It's worth noting that you may want to grab two or three Co-Op partners when working on this achievement for two reasons. One, the extra firepower will help put down enemy forces a little quicker. Secondly, one or two players can usually act as a decent distraction while the remaining two players attempt to push on and run by as many enemies as possible in an attempt to grab the next checkpoint.

This essentially means that you may want to replay individual missions dozens of times in order to perfect your runs and learn new tactics in skipping various firefights.

This essentially means that you can tackle a mission multiple times in an attempt to perfect your speed run.

NOTE: By following the speed running tactics provided in the video above, you will almost certainly obtain the Par Time achievement for each of the Campaign's nine missions. This means that if you have yet to grab the Par Time achievements on the Easy or Normal difficulty setting, they can be stacked on the Legendary difficulty setting while working on this achievement.

You're Joking30
Halo 4: Complete all Halo 4 Legendary campaign missions in under 3 hours.    (31) 

As one of the four Legendary speed running achievements, this achievement will prove to be one of the most difficult tasks within the entire collection. It's worth mentioning that you may want to grab two or three Co-Op partners when working on this achievement for two reasons. One, the extra firepower will help put down Forerunner and Covenant enemies a little quicker. Secondly, one or two players can usually act as a decent distraction while the remaining two players attempt to push on and run by as many enemies as possible in an attempt to grab the next checkpoint.

This means that if you have yet to grab the Par Time achievements on the Easy or Normal difficulty setting, they can be stacked on the Legendary difficulty setting while working on this achievement.

Destination Vacation10
Halo 2: View one of the seasonal signs on Zanzibar in classic multiplayer.    (6) 

On the classic Zanzibar map, there will always be a small sign on the beach near the edge of the tide with a picture of a shark and the warning: “Danger, No Swimming.” At certain times of the year, this sign will change on its own. The following dates are when the sign changes:

  • January 1st (New Year’s)
  • October 31st (Halloween)
  • December 25th (Christmas)

Approach the sign on one of these seasonal dates and zoom in to view the new message presented. The achievement will unlock after viewing the sign for a few seconds.

Eminent Domain10
Halo 2A MP: In Territories, control any 3 Territories simultaneously for 30 seconds.    (2) 

The objective of this gametype is rather simple: control the different territories scattered around the map and hold them for until you reach the score requirement or until the time limit expires. Generally, there are three or four territories and you will need to control multiple in order to win.

All that is required is to fully control three different territories at once and hold them for thirty seconds. This can be obtained in a Custom Game by yourself, so load up the "3 Plots" game type on a small map like Warlord and when the match begins, grab all three plots of land. The achievement will unlock once thirty seconds have passed.

Game Master5
Created and saved 5 Custom Game types.   (2) 

The achievement's description here is quite self-explanatory. From the Main Menu, simply enter the Multiplayer Menu and then load up the Custom Games Menu. This will then allow you to choose whichever game, map and gametype you want to amend.

Once the following three choices have been made, you will enter the Options Menu where you can tinker with the session's gameplay options - such as general traits, weapon, and vehicle settings. You will want to change the settings (such as player movement speed) and press the right thumbstick to save the gametype name and file description. Now repeat this process four more times by changing other gameplay settings and the achievement will unlock.

Gate Your Thirst!5

Please refer below to "BLASTacular!" for more information on the BLAST soda cans.

High Altitude Thirst!5
Halo 2A MP: Found and destroyed the BLAST soda can on Zenith.    (1) 

Please refer below to "BLASTacular!" for more information on the BLAST soda cans.

Invaders Repelled10
Halo 2A MP: In King of the Hill, kill 5 opponents within your controlled hill.    (6) 

The objective of the aforementioned gametype is simple: take control and hold the hill for the longest time or until the time requirement expires. If the game has a moving hill, you may need to search around the map for the new hill periodically. Also, this gametype may be played as a FFA or Team-based game.

All that is required is to kill five enemies that are attacking your position while you are holding the hill. Some useful tactics in pulling this off is to grab close-quarter weapons such as a Shotgun and wait inside the hill until enemies begin to ambush your position. All in all, this achievement is best done in Team King of the Hill in a Custom Game with at least one other player. When the match starts, simply stand in the hill (it won't move locations) and have your partner stand just outside the hill's boundaries. Proceed to kill your partner a total of five times and the achievement will unlock.

Master Forger5
Created and saved 5 Custom Maps in Forge.   (3) 

The achievement's description here is quite self-explanatory. From the Main Menu, enter Forge Mode and load up whichever map you want to tinker with.

Now repeat this process four more times within the same Forge session and the achievement will unlock without any issues.

Power Play10
Halo 2A MP: On Warlord, get every center powerup that becomes available in a single game.    (3) 

In the center structure of Warlord, the invisibility powerup can be found nestled inside the structure's alter. For this achievement, all that is required is to grab the powerup at least five different times within the same match. Take note that this can be done in a Custom Game by yourself. Additionally, the powerup will re-spawn every sixty seconds, so keep an eye on the clock. Once you’ve obtained the power up five times in a single game, this achievement will unlock.

Put Up Your Dukes10
Halo 2A MP: Get 25 melee kills in multiplayer.    (2) 

All that is required of players here is to achieve a total of twenty-five beat downs in Multiplayer. Since this is a cumulative achievement, all your beat downs across different matches will add to the grand total. Generally, there is no one gametype suggested for this, though smaller maps such as Warlord and Shrine will prove to be better options for close-quarter firefights. As always, this achievement will unlock naturally over the course of your Multiplayer career unless you decide to boost it in a Custom Game with another player or second controller.

Red vs. Blue10
Halo 2A MP: Win 10 matches on Bloodline in multiplayer.    (1) 

As a cumulative achievement, simply win ten matches of any gametype on the aforementioned Multiplayer map in order to obtain this achievement. This can be done wit relative ease by starting a Custom Game on Bloodline by yourself and then selecting "End Game" once the match begins. Just repeat this process a total of ten times and the achievement will be yours in no time.

Rule Your Thirst!5

Please refer below to "BLASTacular!" for more information on the BLAST soda cans.

Shields Up!10
Halo 2A MP: On Zenith, personally activate the center energy shield 3 times in one matchmade game.   (12) 

On this map, the central dish structure provides a temporary energy shield when activated by one of three switches located around the boarders of the map. The first of these switches is located inside Comms Tower, the second is located on Sky Bridge, and the third is located on the center ramp where the Shotgun spawns.

The energy shield will usually only last about thirty seconds, so make sure to move towards the switches around the map as soon as possible. Also keep in mind that this must be done in matchmaking and cannot be unlocked in a Custom Game. Once you’ve activated the energy shield three times, the achievement will unlock.

Shook the Hornet's Nest10
Halo 2A MP: Get 30 kills with the Hornet in multiplayer.    (2) 

The Hornet is a UNSC VTOL air support vehicle armed with both anti-infantry (triple-barreled rotary cannons) and anti-vehicle (guided missile launchers) weapon systems. This vehicle only spawns on Bloodline, though this map is perfect for obtaining kills given the large, outdoor landscape between both bases.

Grab another player or second controller and head into a Custom Game. In the lobby, change the player traits under the Slayer gametype so that players do not have shields and all damage is 500% more effective. Once the match starts, have one player pilot the Hornet and station themselves in the center of the map while the other player offers themselves up as free kills. After amassing a total of thirty kills with this vehicle, the achievement will unlock.

Skeet Shooter10
Halo 2A MP: Killed 15 opponents that were airborne from a Man Cannon.    (3) 

This achievement is best done in a Custom Game with another player. Also, keep in mind that Man Cannons are primarily found on the rooftop platform of the bases in the Bloodline map. With that said, grab another player and in the Custom Game lobby, change the player traits under the Slayer gametype so that players do not have shields and all damage is 500% more effective. Additionally, change the starting weapons so that each player spawns with Beam Rifles.

Once the match starts, have one player position themselves in the center of the map while the second player communicates which base they will be utilizing. The second player will want to launch themselves off the Man Cannon while the first player snipes them out of mid-air with a single shot. Continue grinding this out until the achievement unlocks, then switch roles so that your partner can obtain the achievement as well.

Stayin' Alive10
Halo 2A MP: In Juggernaut, survive as the Juggernaut for 30 seconds.    (1) 

In this gametype, two teams will face off in a “cat and mouse” sort of chase. On one team, there is the Juggernaut who acts alone in an attempt to kill as many players on the opposing team. Each kill the Juggernaut obtains will is worth one point. On the other hand, the other team consists of the remaining players in the match and their goal here is to kill the current Juggernaut. After a player kills the Juggernaut, they themselves will assume the role of Juggernaut and can begin amassing points by killing players on the opposite team.

This can be obtained in a Custom Game by yourself, so just load up the aforementioned game type and when the match begins, you will automatically spawn as the Juggernaut. All you have to do is wait thirty seconds and the achievement will unlock with ease.

The Goose is Loose10
Halo 2A MP: Get 25 kills with the Gungoose in multiplayer.    (1) 

In this gametype, two teams will face off in a “cat and mouse” sort of chase. On one team, there is the Juggernaut who acts alone in an attempt to kill as many players on the opposing team. Each kill the Juggernaut obtains will is worth one point. On the other hand, the other team consists of the remaining players in the match and their goal here is to kill the current Juggernaut. After a player kills the Juggernaut, they themselves will assume the role of Juggernaut and can begin amassing points by killing players on the opposite team.

This can be obtained in a Custom Game by yourself, so just load up the aforementioned game type and when the match begins, you will automatically spawn as the Juggernaut. All you have to do is wait thirty seconds and the achievement will unlock with ease.

Thirst Locked Down!5
Halo 2A MP: Found and destroyed the BLAST soda can on Lockdown.    (5) 

Please refer below to "BLASTacular!" for more information on the BLAST soda cans.

Top Gungoose10
Halo 2A MP: Get a kill with the Gungoose while airborne.    (10) 

This vehicle, a standard Mongoose armed with a pair of light anti-infantry machine guns, is new to Halo 2: Anniversary’s Multiplayer. The Gungoose spawns on both Stonetown and Bloodline, though the latter is the best map to work this achievement. Since the landscape of Bloodline is hilly around the center portion of the map, you’ll want to spend time driving the Gungoose here in order to get a kill while airborne.

To get this done quickly, grab a another player or fire up a second controller and change the player traits under the Slayer gametype so that players do not have shields and all damage is 500% more effective. Once the match starts, have one player position themselves away from the dirt hill in the middle of the map while the other player accelerates the Gungoose off the dirt ramp. Be ready to fire your machine guns and because players will not have shields, a single bullet will kill your opponent, thus unlocking the achievement.

BLASTacular!10
Halo 2A MP: Destroyed all the Halo 2 Anniversary Multiplayer BLAST soda cans.    (6) 

BLAST soda cans are hidden Easter Eggs that have been tucked away in the environments of the six remastered Halo 2: Anniverary maps. Due to their size, locating these soda cans will prove to be quite tedious and difficult, so make to follow the video guide illustrated below. Once all six of the soda cans have been located and destroyed, this achievement – as well as the previous six achievements – will be yours.

Bloody Thirsty!5
Halo 2A MP: Found and destroyed the BLAST soda can on Bloodline.   (1) 

Please refer just above to "BLASTacular!" for more information on the BLAST soda cans.

Bombing Run10
Halo 2A MP: In Assault, take, plant, and score from the bomb spawn without dying or dropping it.    (2) 

In this gametype, two teams will face off in an attempt to arm a bomb in the opponent’s base. Typically, there are three variants: Single Bomb, Multi Bomb, and Neutral Bomb. In order to carry out this achievement, players will have to pick up the bomb located at their base or on the map right from the start of the match, carry it to the opponent’s base without every dropping it or dying, arm the bomb, and wait until the countdown expires before the bomb explodes.

Keep in mind that this achievement can be boosted in a Custom Game. Simply start an Assault match on a small map such as Shrine or Warlord with another player or second controller. When the game begins, pick up the bomb at your base and proceed to plant it at the enemy base. Once the bomb explodes, the achievement will unlock so long as you did not drop the bomb nor die by your partner.

Cold as Ice10
Halo 2A MP: On Lockdown, kill an opponent with the hanging ice.    (2) 

On this map, new environmental stalactites have been placed above certain areas of the battlefield as a means of breaking up firefights with alternate means. The first stalactite is located above the Battle Rifle tower, another is located above the top-center platform, and the last stalactite is located just above the ramp behind the Sniper Rifle tower. For this achievement, it's best to start a Custom Game with another player and have them stand underneath the hanging ice. Now shoot the stalactites and it will break and fall, killing your partner and thus unlocking the achievement almost immediately.

Cold Fusion5
Halo 2A MP: Kill an opponent by detonating a Fusion Coil.    (3) 

Fusion Coils are UNSC ground containers that contain superheated plasma. As you would expect, the contents within the container are highly volatile and will kill weakened enemies when the container is destroyed. Lockdown will have many Fusion Coils scattered around the top floor of the middle platform, so start a Custom Game with another player and meet each other here. With a weak weapon, such as the SMG, strip the shields off your opponent and then have them stand next to the Fusion Coil. Now shoot the Fusion Coil with your weapon and the explosion will kill them, thus unlocking the achievement.

Counter-Sniped10
Halo 2A MP: With a Sniper Rifle or Beam Rifle kill an enemy that was zoomed in.    (3) 

Fortunately, the achievement’s description here is quite self-explanatory. Load up a Custom Game on Bloodline with at least one other player. When the match begins, each player should pick up their Sniper Rifle on the top of their home base. Once you have the weapon, meet up anywhere on the map and have one player zoom in with their Sniper Rifle while the other player gets a quick headshot, thus unlocking the achievement. When the second player spawns, simply return the favor. Keep in mind that you must kill the enemy who was zoomed in with a Sniper Rifle or Beam Rifle, as no other weapon will count towards this achievement.

Triple Threat10
Halo 2A MP: In Ricochet, pass once, score once, and kill at least one enemy in the same match.    (7) 

This gametype is a slight variation of the Oddball, where players earn points for throwing the ball into the enemy team's goal and even greater points for running it inside the goal. The first team to reach the required point limit will win the match.

To get this done quickly, go ahead and begin a Ricochet match on Warlord with at least two other players. Two players will need to place themselves on one team (Team A), while the third player resides on the opposing team (Team B) by themselves.

When the match begins, one player on Team A will need to kill the player on Team B. After this first task is done, pick up the ball and pass it to your teammate to complete the second requirement. Finally, make sure your teammate passes the ball back to you so that you can score it at the enemy's goal for the last requirement. If done correctly, the achievement should unlock without any issues once the ball is scored. Make sure that the other two players get their share towards the achievement as well!

Wetwork5
Halo 2A MP: On Shrine in CTF, activate the enemy base waterfall and, before it stops, grab the flag.    (1) 

On this map, you will come to notice bright red/orange devices that are hanging on the ceilings of each base. When shot, the devices will be destroyed and release a waterfall that blocks the lines of sight through the openings of the base. This effect will only last for about thirty seconds before reverting to its original state.

This can easily be done in a Custom Game with another player. When the match begins, you will need to personally destroy the device inside your opponent's base and grab their flag before the waterfall vanishes. The achievement will unlock as soon as you exit their base with the flag.

Worship Your Thirst!5
Halo 2A MP: Found and destroyed the BLAST soda can on Shrine.    (3) 

Please refer below to "BLASTacular!" for more information on the BLAST soda cans.

Zealot10
Halo 2A MP: Win 10 multiplayer games as an Elite.   (6) 

In the Multiplayer Menu of the game, you can choose whether you want your online character model to represent a Spartan or an Elite. Despite any preferences towards a Spartan, this achievement will require you to select the Elite model for Multiplayer. Once you’re desired Elite variant is chosen, all that is required is to win a total of ten Multiplayer games as an Elite and the achievement will be yours. Despite its description not stating this, this must be done in matchmade games.

MVP10
Halo 2A MP: Finished as the top player on the winning team in a matchmade game.   (7) 

At the very end of every Multiplayer match, top players will be designated the Most Valuable Player (MVP). Take note that becoming the MVP for a match is highly dependent on the gametype. Refer below for the criteria across four different gametypes:

  • Team Slayer: Being the player with the most kills
  • Team Oddball: Being the player who has held the Oddball for the longest time
  • CTF: Being the player with the most scored flags
  • Team King of the Hill: Being the player who has spent the most time in the hill

Overall, all that is required for this achievement is to earn the MVP recognition once.

Spartan Ops, the mission-based cooperative multiplayer mode supports up to four players across all 10 Episodes. Each of these Episodes contains 5 small Chapters, meaning that all fifty Chapters must be completed on the Legendary difficulty in order to unlock this achievement. If you decide to go about this through Co-Op play, the missions will prove to be a little easier as opposed to working alone since you will have extra firepower in order to eliminate the Covenant and Promethean threats. On the other hand, if you decide to work on this achievement in a Solo playthrough, you will also make natural progress towards the "Smooth Operator" achievement.

During your Spartan Ops playthrough, you will come to notice that most of the missions take place on recycled environments from the Single Player Campaign or the Multiplayer maps. As such, when playing on these environments, you should have a general understanding of the mission’s design structure and layout. The objectives through all fifty Chapters vary, as well. They will usually range from eliminating all the enemies in the area to defending a group of Marines or UNSC equipment.

Like the Halo 4 Campaign, make sure to keep these general guidelines in mind when powering through Spartan Ops.

  • Utilize the Noob-Combo (Plasma Pistol/Battle Rifle or DMR) at all times when facing Elites and Knights; an overcharged Plasma Pistol shot will drain/break their shields, while a follow-up three-shot burst to the head will kill the enemy
  • Utilize vehicles – Warthogs, Scorpions, and Mantises – whenever they are presented in a mission because their firepower will help clear out areas quickly
  • When facing Hunters, get close enough so that they charge at you as this allows time to side step their attack, and then shoot at the patch of orange flesh on their back (their weak spot)
  • When fighting massive groups of Prometheans, always kill Watchers first since they act as a Knight’s and Crawler’s defense unit by deploying Hardlight Shields, reconstructing fallen allies, and tossing back live grenades.
  • Try avoiding close-quarters combat with Knights since their arm blades will tear you to pieces in one swipe at times; pick them off from afar
  • Don’t neglect the basics of using cover; when your shields drop down, hide behind a wall or crouch behind an object before charging back out into battle

As a final note, it’s worth mentioning that you are given an unlimited pool of lives when playing through Spartan Ops. Unlike the Campaign, deaths do not revert your progress to a checkpoint. Instead, you will respawn in a safe-zone if you happen to die during the mission. All in all, once all fifty Chapters in Spartan Ops have been completed at the Legendary difficulty setting, this achievement will unlock.

Smooth Operator30
Halo 4: Complete all Spartan Ops chapters solo on Legendary difficulty.     (23) 

As of the April 2015 Title Update, the "Save/Quit" method no longer works when attempting to obtain this achievement. Unfortunately, this means that players will need to legitimately finish all 10 Episode (5 Chapters per Episode) on their own in order to earn the achievement.

With this in mind, players should refer to the following general combat tips when playing each Chapter in Spartan Ops.

  • Utilize the Noob-Combo (Plasma Pistol/Battle Rifle or DMR) often when facing Covenant Elites and Promethean Knights; an overcharged Plasma Pistol shot will drain their shields, and a quick precision shot to the head will down the enemies
  • For loadout purposes, equipping Promethean Vision or Hardlight Shield may prove to be the wisest choice in terms of armor abilities
  • When facing Hunters, get close enough so that they charge at you, allowing time to side step their attack; when the orange flesh on their back is exposed, shoot it, as this is their only weak spot
  • When squaring off against the Promethean Knights, be quick to kill their Watchers first since these AI act as a Knight’s defense unit
  • Try avoiding close-quarters combat with Knights; their arm blades will tear you to pieces in one swipe at times
  • Don’t neglect the basics of using cover; when your shields drop down, hide behind a wall or crouch behind an object before charging back out into battle
It is worth mentioning here that players will have an UNLIMITED AMOUNT of lives during Spartan Ops. As such, do not be hesitant in rushing the enemies when necessary, especially if you desire to quickly activate/reach an objective rather than killing every enemy on the field. Also, the Chapters do not need to be completed in any specific order, so feel free to jump around if you fancy.

Once all 50 Chapters have been completed Solo, on Legendary difficulty level, this achievement will finally unlock.

Roses vs Violets5
Halo 4: Why are you even here?   (5) 

The best place to get this achievement is on Episode 1, Chapter 5. After the first major firefight, you will reach the top of the Forerunner bridge-like structure that leads to the first objective. At this point, follow the outer wall that lines this area until you find a small break in the wall that you can look through. If you jump on the ledge and look down into the molten rocks, you will find a small chest sitting on the rocks. Go ahead and shoot this chest with any weapon in order to unlock the achievement. If you require a visual aid in obtaining this achievement, make sure to check out the video guide below.

No One Left Behind10
Halo 4: Save at least one Marine on Hacksaw (Ep.2 Ch.3) of Spartan Ops on Heroic or Legendary.    (8) 

This achievement is best done cooperatively with 2-3 other players since the extra firepower will prove to be beneficial when eliminating the Covenant enemies in the area. In total, there are about 6-8 Marines that you will need to protect throughout the duration of the mission. They will generally follow you around and provide support, but take note that they aren’t necessarily strong enough to kill Elites, Hunters, and Jackals on their own. Despite this, with a 2-3 other players, protecting at least one Marine should be pretty easy.

As soon as the mission beings, you will notice that the area is actually a recycled environment from the Campaign’s “Forerunner” mission. Walk around to each of the small bases in the corners of the area to locate the Marines. Help them take out the immediate Covenant threat and once the Elites, Grunts, and Jackals are killed, the Marines will begin following you. At this point, two players should lead the Marines to the top of the central structure in order to hold the upper ground advantage over the Covenant. The third player (or other two players if you’re playing with a full lobby) should remain stationed on the ground in order to flush out the Covenant head-on.

From here on out, a few Covenant Phantoms will begin to drop off waves of enemies, some of which even drop of a Wraith. At the top of the central structure, there are a few Spartan Lasers and Rocket Launchers, both of which will be beneficial in eliminating the ground troops from afar. The players on the ground should arm themselves with a Plasma Pistol and Battle Rifle/DMR in order to pull off quick Noob-Combos on the Covenant Elites. With the group of players split between the top level of the structure and the ground level, you should have no problem killing the Covenant quickly while ensuring the Marines are kept alive. If at any point you think it’s necessary, go ahead and give one or two of the Marines a Rocket Launcher for safety. Also, the player(s) on the ground should eliminate the Elite Zealots (wielding Energy Swords) as quickly as possibly before the Elites storm the top of the structure and kill the Elites.

Towards the end of this mission, two Covenant Phantoms will linger overhead and you will be required to destroy them via Spartan Laser/Rocket Launcher before evac can arrive. Once these ships are destroyed, the achievement will unlock as you approach the Pelican so long as at least one Marine is still alive.

Knight in White Assassination5
Halo 4: Assassinate a Knight in any Spartan Ops mission.   (5) 

The best chapter to get this achievement is on Episode 1, Chapter 4. In addition to this, it’s highly recommended to create a Halo 4 custom loadout through the “customization” tab of the Main Menu with the Promethean Vision armor ability.

After completing the inital objective (activating the switch) at the start of this mission, clear out the room of Crawlers and stat heading back out of the hallway that you came from. At this point, you will be informed via Palmer that there is a Promethean Knight around the corner. As soon as you hear this, activate Promethean Vision in order to track the Knight’s movement. You will notice the Knight paces back and forth down the hallway. As soon as its back is turn, run up behind the warrior and hold your melee button to perform an assassination, thus unlocking the achievement.

If you are playing this mission with another player, you can avoid the “sneaky route” by allowing one player to distract the Knight while the second player runs up behind for an assassination. For a visual guide in completing this achievement, go ahead and check out the video below.

What Power Outage?10
Halo 4: Complete The Cauldron Base of Spartan Ops without losing a generator on Heroic or Legendary.    (4) 

This achievement is actually best done cooperatively with only one other player. This is because when this mission is played solo or with two players, Mantises are provided as the means of vehicular firepower. When playing with three or four players however, these Mantises are replaced with Gauss Warthogs, which prove to be inferior to the firepower of a Mantis. With that said, each player should hop in their Mantises as soon as the mission begins and move through the canyon valley until they reach the group of UNSC Marines and two large generators. Take note that there are two extra Mantises on the platform behind the generators in the event that your starting Mech is destroyed.

The objective during this entire mission will be to protect both generators on the Forerunner platform from the oncoming waves of Covenant units. The Covenant will usually be dropped into the mission in one of two ways. Phantoms will drop small groups of six to eight Grunts off at the perimeter of the platform on both the left and right side while at other times, drop-pods will invite three to four Elites in the center of the platform.

Generally, there is no definitive guide that can detail the strategies involved with protecting the generators during this mission. Simply communicate with your teammate and utilize the firepower (machine gun turret and rocket pods) of the Mantis in order to eliminate the Covenant threat before they even have a chance to get near the generator and damage it with their weapons or melee attacks. Since the platform here is tight, each player should maintain their position on one end of the platform rather than pacing back and forth and getting caught on the walls. There are about eight waves of enemies that will storm the platform, but once they are all eliminated, the achievement will unlock before the mission requires players to proceed to the next mini-objective.

No Easy Way Out10
Halo 4: Survive Spartan Miller (Ep.5 Ch.1) of Spartan Ops on Heroic or Legendary.    (8) 

Despite the achievement’s description leading players to believe that this mission must be completed with dying, that’s not the case at all. In fact, this achievement will unlock so long as you simply complete the initial objective of this mission. That objective is rather simple: Activate the two UNSC terminals and protect at least once of them from the dozen waves of Promethean enemies.

As a general note, this achievement is best done on Heroic with 1-3 other players. The extra firepower is great when picking off Watchers and Crawlers and facing off against Knights. Towards the end of this mission, the waves of enemies will begin to die down a little bit and you will be required to activate a new switch on the equipment on the central structure. Before doing this, make sure to kill the two Knights on the top level of this structure and any other Promethean enemies that spawn into the area after these Knights’ death.

Once the entire area is clear of enemies, you will unlock the achievement and can now proceed to activate the switch and continue with the mission's objective(s) as normal. Remember, you can die as many times as you want, as it does not void anything related to the achievement.

Nice Work Dawg!5
Earn a total of 2,500 Assist medals in multiplayer.    (3) 

This Multiplayer medal is represented by a red and white Yin and Yang symbol and is available in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, and Halo 4. It is awarded to players upon assisting a teammate in achieving a kill. Though this achievement can obviously be done in regular matchmaking as progress will be obtained naturally, this is best boosted with at least three players in Forge. To do that, be sure to follow the steps below:

  • Enter Halo 2’s Forge through the Main Menu’s Multiplayer tab and set the map to Nebula
  • Have all three players meet up on the single platform
  • Enter Editor Mode and move the white respawn point to the edge of this platform
  • One player will act as the “Dummy” player and kill themselves by jumping off the platform
  • Player “A” will stand to “Dummy’s” side and melee him as soon as he spawns
  • Player “B” will then beat down “Dummy” in the back, causing Dummy to fall off the platform
  • This will give Player “A” an assist medal and Player “B” will receive a Beat Down medal for the "Dim Mak" achievement
  • ”Dummy” will respawn at the edge right away
  • Repeat this process for as long as necessary

As a note, make sure to tweak the gameplay options in the Forge lobby under “Options” before loading up the match. Under “Respawn Time,” change it to “Instant.” This will allow the “Dummy” player to respawn as soon as they are killed, giving Players “A” and “B” nearly 250 assists/beat downs every seven minutes minutes. Once you have obtained 2,500 Assist medals, this achievement will unlock.

Aim for the Head10
Earn a total of 2,500 Headshot medals in multiplayer.    (2) 


This Multiplayer medal is represented by a “targeted” skull and only earned via a precision weapon in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, and Halo 4. It is awarded to players upon killing an opponent by shooting them in the head. Though this achievement can obviously be done in regular matchmaking (best done in SWAT) as progress will be obtained naturally, this can also be boosted with at least three players in Forge. To do that, be sure to follow the steps below:

  • Enter Halo 2’s Forge through the Main Menu’s Multiplayer tab and set the map to Nebula
  • Have all three players meet up on the single platform
  • Enter Editor Mode and move the white respawn point to the edge of this platform
  • One player will act as the “Dummy” player and kill themselves by jumping off the platform
  • Player “A” will stand to “Dummy’s” side and melee him as soon as he spawns
  • Player “B” will then perform a headshot on “Dummy,” causing Dummy to fall off the platform
  • This will give Player “A” an Assist medal for the "Nice Work Dawg!" achievement and Player “B” will receive a Headshot medal
  • ”Dummy” will respawn at the edge right away
  • Repeat this process for as long as necessary

As a note, make sure to tweak the gameplay options in the Forge lobby under “Options” before loading up the match. Under “Respawn Time,” change it to “Instant” and then under “Player Traits – Weapons and Damage,” change the primary weapon to a Beam Rifle and give it a bottomless clip. This will allow the “Dummy” player to respawn as soon as they are killed, giving Players “A” and “B” nearly 250 headshots/assists every seven minutes. Once you have obtained 2,500 Headshot medals, this achievement will unlock.

Dim Mak10
Earn a total of 250 Beat Down medals in multiplayer.    

This Multiplayer medal is represented by a masked ninja icon and is available in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, Halo 3, and Halo 4. It is awarded to players upon killing an opponent with a melee attack from behind (not to be confused with a melee kill medal). Though this achievement can obviously be done in regular matchmaking as progress will be obtained naturally, this is best boosted with at least three players in Forge. To do that, be sure to follow the steps below:

  • Enter Halo 2’s Forge through the Main Menu’s Multiplayer tab and set the map to Nebula
  • Have all three players meet up on the single platform
  • Enter Editor Mode and move the white respawn point to the edge of this platform
  • One player will act as the “Dummy” player and kill themselves by jumping off the platform
  • Player “A” will stand to “Dummy’s” side and melee him as soon as he spawns
  • Player “B” will then beat down “Dummy” in the back, causing Dummy to fall off the platform
  • This will give Player “B” a Beat Down medal and Player “A” will receive an Assist medal for the "Nice Work Dawg" achievement
  • ”Dummy” will respawn at the edge right away
  • Repeat this process for as long as necessary

As a note, make sure to tweak the gameplay options in the Forge lobby under “Options” before loading up the match. Under “Respawn Time,” change it to “Instant.” This will allow the “Dummy” player to respawn as soon as they are killed, giving Players “B” all 250 Beat Down medals about ten minutes or so. Once you have obtained the 250 Beat Down medals, this achievement will unlock.

Domination10
Earn a total of 100 Legendary medals in matchmade games.   (42) 

Legendary medals are among the top-tier of medals in Halo: The Master Chief Collection and are awarded to players for performing specifically tough feats during Multiplayer. Take a look below for all the Legendary medals and their requirements.

  • Extermination – Wipe out the enemy team with at least an overkill
  • Killionaire – Kill 10 opponents within 4 seconds of each other
  • Perfection – Win a slayer game with 15+ kills without dying
  • Steaktacular – Play in a matchmade slayer game and win by at least 20 kills
  • Triple Double – Finish a game with double-digit: kills, assists, and headshots
  • Unfriggenbelievable – Kill 40 enemies in a row without dying

All of these Legendary medals can be obtained in any of the games with the exception of the Unfriggenbelievable medal not being available in Halo 3. Overall, most of these medals are extremely difficult to achieve and there is no definitive boosting method in order to obtain them. With a party of four players however, Team SWAT is one of the best playlists to work on this achievement because the matches are relatively quick and no shields translates to a greater chance of gaining an Extermination medal. Additionally, coordinated teams also have a greater chance in achieving a Steaktacular if they can finish the match with at least twenty kills more than their opponents. Once you earn a total of 100 Legendary medals, this achievement will unlock.

NOTE: As of now, the ONLY game that gives Legendary medals (consistently) is Halo 2: Anniversary. There is confirmation across many gamers that the other three games, regardless of game type, does not give Legendary medals even when the criteria has been met. Thus, stick to all the H2A-focused playlists (H2A, HCS, Team SWAT) when working on Legendary medals.

Double Trouble10
Earn a total of 250 Double Kill medals in matchmade games.   (5) 

This Multiplayer medal is represented by two stars within a purple circle and is available in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, Halo 3, and Halo 4. It is awarded to players upon killing two opponents within four seconds of each other. Like the Legendary medals achievement, and mostly of all of achievements that will follow this one, there is no definitive way to boost Double Kill medals.

You'll need to work with a coordinated team in order achieve two kills within such a short time frame. Team SWAT is one of the best playlists to work on this achievement since players are automatically stripped of their shields, thus meaning you can gain Double Kills a little easier than in a standard Team Slayer game. Once you achieve 250 Double Kill medals, this achievement will unlock.

Spree Master10
Earn a total of 100 Killing Spree medals in matchmade games.   (5) 

This Multiplayer medal is represented by a white and blue circle and is available in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, Halo 3, and Halo 4. It is awarded to players upon killing five opponents in a row without dying. Once again, there is no definitive way to boost Killing Spree medals.

Team SWAT and Big Team Battle are two of the best playlists to work on this achievement. The former automatically strips players of their shields, thus meaning you can gain kills and sprees quickly if your reflexes are sharp. The latter allows for larger teams, which means there are more enemies to kill, especially if they are grouped together in vehicles such as a Warthog. With these tidbits in mind, make sure to stick to one of the two playlists suggested and Killing Sprees may come quicker than in any other playlist. Once you achieve 250 Killing Spree medals, this achievement will unlock.

Catch This10
Earn a total of 500 Grenade Kill or Plasma Kill medals in matchmade games.   (6) 

These Multiplayer medal are represented by a white grenade/plasma grenade icon and are available in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, and Halo 4. The former is awarded to players upon killing an opponent by using a Fragmentation Grenade or Pulse Grenade while the latter is awarded to players for killing an opponent by using a Plasma Grenades. Like the above achievements, there is no definitive way to boost Grenade Kill and Plasma Kill medals.

The best playlists to work on this achievement are Halo Champion Series or Rumble Pit. The former only offers three maps (Lockdown, Shrine, and Warlord), though these maps (especially Warlord) are great for Grenade/Plasma Kill medals on objective matches such as King of the Hill. The latter of these playlists is also a great option because it’s essentially a Free-for-All match. This means that everyone is competing for their own interests, meaning you can probably nab a few kills via grenades while other playes are fighting each other and duking it out. Once you achieve 500 Grenade Kill or Plasma Kill medals, this achievement will unlock.

Party Pooper10
Earn a total of 250 Killjoy medals in matchmade games.   (14) 

These Multiplayer medal are represented by a white grenade/plasma grenade icon and are available in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, and Halo 4. The former is awarded to players upon killing an opponent by using a Fragmentation Grenade or Pulse Grenade while the latter is awarded to players for killing an opponent by using a Plasma Grenades. Like the above achievements, there is no definitive way to boost Grenade Kill and Plasma Kill medals.

The best playlists to work on this achievement are Halo Champion Series or Rumble Pit. The former only offers three maps (Lockdown, Shrine, and Warlord), though these maps (especially Warlord) are great for Grenade/Plasma Kill medals on objective matches such as King of the Hill. The latter of these playlists is also a great option because it’s essentially a Free-for-All match. This means that everyone is competing for their own interests, meaning you can probably nab a few kills via grenades while other playes are fighting each other and duking it out. Once you achieve 500 Grenade Kill or Plasma Kill medals, this achievement will unlock.

Planting A Flag10
Earn a total of 250 CTF Mode Specific medals in matchmade games.   (12) 

In total, there are twelve Capture the Flag Mode Specific medals that can be earned in Halo: The Master Chief Collection. You can take a look below to see what medals count towards this achievement.

  • Flag Taken – Take an opponent’s flag from their base (H:CE, H2, H2A)
  • Flag Returned – Return your flag to your base (H:CE, H2, H2A)
  • Flag Captured – Capture the opposing team’s flag (ALL GAMES)
  • Flag Runner – Capture 2 flags in one game (H:CE, H2, H2A, H4)
  • Flag Champion – Capture 3 flags in one game (H:CE, H2, H2A, H4)
  • Flag Assist – Help a teammate capture a flag (H2A, H4)
  • Flag Carrier Kill – Kill the opposing flag carrier (ALL GAMES)
  • Flag Defense – Kill an opponent who is close to your flag (H2A, H4)
  • Flag Kill – Get a kill while holding a flag (ALL GAMES)
  • Flagassination – Perform an assassination while holding the flag (H4)
  • Flag Joust – Kill a flag carrier while holding the flag (H2A, H4)
  • Flag Driver – Drive a flag carrier close to your capture point (H2A, H4)

With all of this in mind, disregard anything about the medals above and focus on the method that is about to be explained below.

To begin, you will want to grab five other players so that you have a party size of six. Make sure everyone has microphones and can communicate effectively. Now designate one of the members in your party as the “Countdown Person.” This group of six will now need to split off into two parties of three. While each party is sitting at the Multiplayer Main Menu, the session leader will need to highlight Halo: Combat Evolved. At this point, the “Countdown Person” will need to announce, “3, 2, 1, Now.” When the “Countdown Person” says “Now,” the session leaders will need to activate the Halo: Combat Evolved playlist to begin searching for a game.

While searching, both parties will need to communicate via party chat and make sure that the lobby’s status is the same for both groups of three, (e.g. “Players Found,” “Joining Game,” and “Creating Teams”). If you are getting the same status updates in the lobby, you will most likely be matched up with each other. If you don’t get paired up, simply quit out of the game that you join and restart the process.

Once both parties are in a game together, you will want to hope that Capture the Flag is one of the options is the match selection screen. If a CTF match is chosen, wait until the game begins and then have one player from each team pair up with another. With these smaller groups created, head on over to one of the flags on the map. The player who is the same color as the flag will be deemed as the “Flag Retriever.” On the other hand, the person who is the opposite color as the flag willed be deemed as the “Flag Grabber.”

Now have the “Flag Retriever” stand exactly on the flag’s spawn plate. The “Flag Grabber” just has to grab the enemy’s flag and stand right in front of the “Flag Retriever” who should still be standing on the flag’s spawn plate. The “Flag Grabber” now has to look at the “Flag Retriever” and tap the right trigger. This will cause the “Flag Grabber” to toss the flag back at the “Flag Retreiver” who will earn the Flag Returned medal. At the same time, the “Flag Gabber” will automatically pick the flag back up and earn the Flag Taken medal. All you have to do now is have the “Flag Grabber” spam the right trigger and both players will earn medals within seconds. In fact, this entire achievement can be knocked out of the way within 2-3 minutes if done properly.

If you need a visual aid in understand this complicated boosting method, go ahead and utilize the video below. Also, it’s worth noting that this boosting method could be manipulated to suit the other matchmade-only multiplayer achievements, but setting it up could be very problematic since other playlists require more players than the Halo: Combat Evolved playlist and are more populated than the Halo: Combat Evolved playlist. Either way, once you achieve 250 Capture the Flag Mode Specific medals, this achievement will unlock.

The True King10
Earn a total of 250 KOTH Mode Specific medals in matchmade games.   (13) 

In total, there are thirteen King of the Hill Mode Specific medals that can be earned in Halo: The Master Chief Collection. You can take a look below to see what medals count towards this achievement.

  • Hill Defense - Kill an enemy while holding a hill (ALL GAMES)
  • Hill Offense - Kill an enemy holding a hill (ALL GAMES)
  • Hail To The King - Kill 5 consecutive opponents in a single life from inside the hill before it moves (ALL GAMES)
  • Hill Assist - Assist killing an enemy taking or holding the hill (H4)
  • Regime Change - Overtake a controlled hill (10 seconds) and hold it for 10 seconds (H4)
  • First Point - Be the first player to earn a point from a hill (ALL GAMES)
  • Loitering - Hold and survive the hill for 5 seconds (H2A, H4)
  • Squatter - Hold and survive in the hill for 15 seconds (H2A, H4)
  • Over the Hill - Hold and survive the hill for 30 seconds (H2A, H4)
  • Vehicle Dominance - Use a vehicle to hold a hill (ALL GAMES)
  • Visiting - Hold and survive in the hill for 5 seconds using a vehicle (H2A, H4)
  • Parked - Hold and survive in the hill for 15 seconds using a vehicle (H2A, H4)
  • Drive In - Hold and survive in the hill for 30 seconds using a vehicle (H2A, H4)

With all of this in mind, the best playlist to work on this achievement is Team SWAT. This is because objective game modes like King of the Hill will appear more often than in any other Multiplayer playlist. In addition to this, Team SWAT is much easier to earn KoTH medals because since all players are stripped of their shields, kills for medals such as Hill Offense and Hill Defense will come easier than in a standard King of the Hill match.

The most difficult aspect of this achievement is to wait until King of the Hill is actually voted for in the Multiplayer map selection menu. A decent way to circumvent the negative possibility of KoTH not getting chosen is to play with a group of three to four other players. This increases the chances of KoTH being voted for since your entire party can vote for King of the Hill once it appears. Overall, this achievement only goes as fast as your skill level in the aforementioned game type. Once you achieve 250 KoTH Mode Specific medals, this achievement will unlock.

Roadkill Rampage10
Halo 2A MP: In Anniversary matchmaking, earn a total of 100 Splatter medals.   (20) 

This Multiplayer medal is represented by a bloodied stickman inside a yellow diamond and is available in Halo: Combat Evolved, Halo 2 Classic, Halo 2: Anniversary, Halo 3, and Halo 4. It is awarded to players upon hitting and killing an opponent with a vehicle (Warthog, Gungoose, Ghost). Despite being available in all the games, this achievement requires players to earn Splatter medals in Halo 2: Anniversary matchmaking only. Unfortunately, there is no easy way to boost this, so be prepared to play on Bloodline and Stonetown a lot, as these are the only two H2A maps that house vehicles.

When working on this achievement, you'll want to stick to the Big Team Battle or Team Slayer playlists. Both of the aforementioned maps will appear in this playlist, though you'll come to notice that they have and extremely low probability of showing up. If you want to try other playlists, Team Halo 2: Anniversary and Halo 2: Anniversary Rumble houses Stonetown, and Lockdown's (found in Team Halo 2: Anniversary, Halo Championship Series, Halo 2: Anniversary Rumble and Team SWAT) stalactites often time net a Splatter medal when an Environmentalist medal is earned (though this isn't 100% guaranteed).

All three maps work well for this achievement and it's just a matter of which playlist you want to try out. If you happen to go with the two bigger maps, keep the following in mind: Bloodline houses a Warthog and Ghost at each base and there a couple Gungooses scattered around the map as well. As for Stonetown, there are two Warthogs, one Gungoose and one Ghost at the beach-side spawn as well as one Warthog and one Ghost outside the perimeter of the complex. Splatters may prove to be quite the burden when playing Slayer or Objective matches on these matches, but if you aim small and try to get at least three to five Splatter medals per game, this achievement will be less of a difficult task and more of a focused-grind. Once you achieve 100 Splatters medals, this achievement will unlock.

Rock and Coil Hit Back10
Halo 2A MP: In Anniversary matchmaking, earn a total of 100 Environmentalist medals.   (34) 

This Multiplayer medal is represented by a black skull inside a yellow triangle and is only available in Halo 2: Anniversary. It is awarded to players upon killing an opponent with any dynamic element in the level. This includes - and is unfortunately limited to - the stalactites in Lockdown, as well as the fusion coil barrels in both Lockdown and Stonetown. As a final reminder, this achievement will take quite a while to earn as there is no definitive way to boost Environmentalist medals.

Since there are only two maps that allow players to receive these medals, you're best bet when playing Multiplayer is to stick to the following playlists: Halo Championship Series or Team SWAT. Lockdown will appear in both playlists (more commonly in HCS). Stonetown on the other hand will appear in Team Halo 2: Anniversary, Halo 2: anniversary Rumble, Team Slayer, and Big Team Battle. Despite this, Team Slayer and Big Team Battle are not recommended because Stonetown has a very low probability of appearing as one of the maps. It has a greater chance of appearing in Team Halo 2: Anniversary and Halo 2: Anniversary Rumble, however Stonetown doesn't have as many fusion coils as Lockdown.

With this in mind, stick to the Halo Championship Series playlist or the Team SWAT playlist. Environmentalist kills are not always guaranteed every match, however if you're keen on shooting down the stalactites every so often during a match - or happen to shoot a fusion coil while an opponent is camping near the "Sniper Tower" or above the "BR Tower" - you may be lucky enough to earn yourself an Environmentalist medal if these objects kill the enemy player.

All in all, this achievement goes only as far as a player's luck and skill in luring enemies into these environmental trap, so you'll need to dedicate a decent amount of time to Lockdown in order to get this done. Once you achieve 100 Environmentalist medals, this achievement will unlock.

No Pain, No Gain10
Complete 1 mission with the LASO playlist skulls enabled.   (5) 

This achievement is in fact retroactive and will unlock if you have already completed any of the many missions in a Campaign’s LASO playlist. As some players have reported however, such retroactive progress will cause the achievement to be stuck at the “Done! Unlocking…” phase in the Xbox One’s achievement app. If this happens, you will need to simply wait until the achievement finishes unlocking itself (this may take days or weeks to happen).

If you have not already met the criteria for this achievement, you will need to complete a Campaign mission from Halo: CE, Halo 2, Halo 3, or Halo 4 with that game’s LASO playlist skulls activated. While some players have reported that completing Halo 2’s “Armory” mission with the LASO playlist skulls activated will unlock this achievement (or even Halo 3’s “Epilogue”), this method is not working for everyone.

If you are one of those who cannot unlock the achievement in such a way, you will need to find another mission and power through it with the appropriate skulls. Halo: CE’s “Keyes” or Halo 2’s “Uprising” both have extremely beneficial exploits that can skip more than half of the mission. As such, it’s suggested to learn the “Keyes Bump” or Uprising’s “early level finish” exploit in order to then complete these missions with the Campaign’s LASO playlist skulls activated. If you are successful in performing this feat, this achievement will then unlock.

Airborne10
Halo CE: Launch a Warthog for at least 5 seconds and have it splatter an enemy.    (16) 

This achievement is obtained in a Halo: Combat Evolved Custom Game with a bare minimum of three players. While this can technically be done on your own with two extra controllers, it will prove to be too difficult as opposed to teaming up with two other players who have microphones and can communicate via an Xbox Live party chat.

With that said, go ahead an host a Custom Games lobby and invite the two other players. The person going for this achievement should try to be host, though that is not entirely necessary. Before launching the game, you're going to need to tweak the options a little bit. First off, select the map called "Death Island" and change the game type to Team Slayer. Player "A" (host) will be going for the achievement and should be on a team with Player "B." Player "C" will need to be on their own team. Now under options, go ahead and turn friendly fire off, change the primary weapon to a Rocket Launcher, turn off Banshees for both teams, set the time limit to "none," and set grenades to "infinite." Once all these options are in place, go ahead an launch the game.

When the match begins, Player "A" will need to grab one of the many Warthogs around the island and drive up to the top of the map. Player "A" needs to line up their Warthog with the tip of Red Base's Ghost spawn and then drive back in order to put some distance between the Warthog and the Ghost. Driving back to the rock/trees is far enough. At this point, Player "B" should stand off to the side of the Ghost with Plasma Grenades equipped while Player "C" stands at the beach in front of Red Base. It's worth noting that Player "A" will be the driver (person getting the achievement), Player "B" will be the "launcher," and Player "C" is going to be the player that gets splattered.

Once everyone is in position, Player "A" needs to accelerate the Warthog forward and steer straight into the Ghost because it will act as a mini-ramp for the Warthog. When the Warthog is a few feet from the Ghost, Player "B" needs to throw one Plasma Grenade at the front of the Ghost. Player "A" will drive over the grenade and over the Ghost, which is when Player "B" will shoot a single rocket at the ground behind the Warthog. If timed correctly, though timing does not need to be that exact, the Plasma Grenade will go off as soon as the rocket explodes, thus "launching" (as the achievement's description requires) the Warthog high into the air off of Red Base. This double explosion will more than likely always grant five to six seconds of airtime.

Player "C" now has to essentially "catch" the Warthog by moving around and positioning themselves underneath the vehicle as it descends. It's important to note that Player "C" cannot jump into the Warthog. Rather, the Warthog needs to crush Player "C" while still in the air. Essentially, the Warthog cannot touch the ground before it kills Player "C." If done correctly, Player "A" will receive a Splatter medal and the achievement should unlock with issue.

For a visual aid in completing this achievement, you can use the video guide below courtesy of LifeExpectancy. His video guide is a little different than the solution offered above, however you will notice that this guide's solution avoids the issues of having Banshees spawn on top of Red Base and thus reducing the acceleration of the Warthog, avoids the probability of Player "B" killing Player "A" since friendly fire is turned off, and guarantees a bigger launch with more airtime due to the dual explosion from the Plasma Grenade and Rocket Launcher blast.

Unlike the Campaign skulls however, these Multiplayer skulls do not act as additional gameplay modifiers. Instead, their only reward is the achievement. Despite this, make sure to utilize the video below in order to locate all six Multiplayer skulls and this achievement, as well as the six that precede it, will unlock without issue.

Well...Maybe One or Two20
H3: ODST: Kill 25 Engineers.   (5) 

As one of the only new “enemy” types in Halo 3: ODST, Engineers will be found frequently during the eight missions of the Campaign and around the streets of New Mombasa. Though players will most likely not even kill more than 10 during a natural playthrough of the Campaign, there’s a perfect “grinding” spot where this achievement can be earned quickly. 

During Kikowani Station, proceed through the mission as normal; grab a Banshee, wait for your allies to board a Phantom, open the first gate, head through the service tunnel, and emerge into the second outdoor area. In this area, begin to pilot the Banshee north towards the next objective and you should grab a checkpoint mid-flight. What’s more, directly ahead of you are four Engineers hovering around a Covenant beacon. As soon as you spot them, open fire with the Banshee’s turrets and fuel rod cannon, though take note that even on Easy these aliens take quite a few hits to kill. Once all four Engineers are dead, revert your checkpoint and continue to grind out the kills in this location until the achievement unlocks.

H3: ODST: Complete every level of the game on Legendary difficulty.      (17) 

This achievement will unlock once Mombasa Streets, all eight missions, and the cut scenes (Prepare to Drop and Epilogue) of the Halo 3: ODST Campaign have been successfully completed on either a solo or cooperative Legendary playthrough. It is recommended that you play through the game's Legendary Campaign playlist so that this playthrough will also contribute toward the "Trifecta" achievement. 

Take note that "Mombasa Streets" is treated as one level, with each visit set as a different Rally Point. This means that after completing the first street segment (before Tayari Plaza), you can skip all of the following visits by quitting the Campaign and selecting the next mission through the Campaign lobby menu, provided you aren't playing as part of a playlist. If you do this you will have to return to these points later on for all the clue related achievements, though you can do so on Easy rather than Legendary.

Unlike the other games in the series, most of the missions in this campaign are very linear or “defense based,” and simply don’t have the “out of map” or “rushing” tactics some players may be familiar with from Halo 2 or Halo 4. Despite this, keep these general tips in mind when playing:

  • Utilize the Noob-Combo (Plasma Pistol/Pistol) at all times when facing Brutes; an overcharged Plasma Pistol shot will drain their shields, and a quick Pistol round to the head will guarantee a kill
  • In Uplift Reserve, utilize the Covenant Ghosts to quickly pass through the entirety of the mission as if you were speed running, thus lessening the amount of killing needed and overall time spent on the mission
  • When squaring off against Drones in Data Hive, keep a Covenant Carbine or Beam Rifle on hand; it’s the best weapon to use against these pesky, agile flyers.
  • Don’t neglect the basics of using cover; when your “shields” drop down, hide behind a wall or crouch behind an object before charging back out into battle
  • Don’t hesitate in giving your power weapons (Rocket Launcher, Fuel Rod Cannon, etc.) to mission-essential NPCs (such as Mickey during ONI Alpha Site or Buck during NMPD HQ and Coastal Highway) as they are invincible and have unlimited ammo

Overall, because seasoned Halo players will be familiar with both level design and enemy behavior, completing the entire Campaign on Legendary will be quite easy. Once all the missions in Halo 3: ODST have been completed on the Legendary difficulty setting, this achievement will be yours.

H3: ODST: Find all 30 Audio Logs.    (10) 

In total, there are 30 audio logs within the Campaign of Halo 3: ODST. Specifically, they are split between 29 in the New Mombasa streets and 1 in the seventh mission, Data Hive. These audio log collectibles are extremely well-hidden and come in the appearance of an telephone booth or computer terminal. At times, you will find that some are only obtainable for reaching obscure locations via deep exploration. Needless to say, it will take a tremendous amount of tracking the Streets to locate these logs. 

What’s more, the 30th of these audio logs will not appear in Data Hive until all 29 have been collected first. It’s best to collect these logs in a solo playthrough on the Easy difficulty setting. Although the collectible achievements can be earned in a Co-Op session of New Mombasa streets when one person grabs a log, when the host ends the game to load up Data Hive, in-game Co-Op progress is not saved and it will read your playthrough as having no logs (unless you were the one to directly collect the audio log). As such, it’s best to work on this achievement on your own, preferably post-game by loading up “Mombasa Streets” in the Campaign Menu. Once all 30 logs have been collected, this achievement will unlock.

Can't Stop Here, This is Brute Country20
H3: ODST: Beat par time on all Halo 3: ODST levels.   (3) 

Before anything, make sure to turn on "Timing HUD" in the Campaign Lobby before starting a mission. This will give you a nice way of tracking your mission time during your playthrough. In order to beat the Par Time on all eight missions with Halo 3: ODST’s Campaign, you will want to take two things into account. 

First, play on the Easy difficulty setting so that enemies aren't as dangerous. Secondly, don't bother turning on any skull modifiers in the lobby. It’s worth noting that unlike the other games in the series, Halo 3: ODST’s missions do not contain many exploits for skipping firefights. What’s more, several of the missions contain “wave defense” or “hold-your-position” segments which cannot be skipped and which will definitely take some time. With these tips in mind, you should have no problem completing each mission under Par Time. 

You can use the checklist below for a reference on each mission’s Par Time:

  • Tayari Plaza - 3:00 minutes
  • Uplift Reserve – 4:00 minutes
  • Kizingo Boulevard – 9:00 minutes
  • ONI Alpha Site – 13:00 minutes
  • NMPD HQ – 10:00 minutes
  • Kikowani Station – 10:00 minutes
  • Data Hive – 16:00 minutes
  • Coastal Highway – 25:00 minutes

Overall, just remember to play on the lowest difficulty setting and try rushing past as many firefights (when possible). Once you beat the Par Time for all eight missions, this achievement will unlock.

The Marine Corps Gives Its Regards20
H3: ODST: Beat par score on all Halo 3: ODST levels.   (4) 

Before anything, make sure to turn on "Scoring HUD" in the Campaign Lobby before starting a mission. This will help you keep track of your score during your mission playthroughs. In order to achieve the Par Score on all eight missions with Halo 3: ODST's Campaign, you will want to take four things into account. 

First, it is in my experience that most missions, when played on Legendary, did not require the activation of any skulls in order to reach a mission’s Par Score. The only mission that really needed skull activation and difficulty tweaking was Coastal Highway, which was set to Heroic with the Famine, Thunderstorm, and Tough Luck skulls. Secondly, Par Scores can be obtained in Co-Op play, so playing with another player or two will definitely help here. Thirdly, you will want to try completing the mission as quickly as possible (finishing under Par Time will give a x3 multiplier to your final score) while still killing everything on the battlefield via headshots and multikills; do leave anyone alive. Lastly, if you do happen to run over Par Time, try picking up the pace as the time multiplier will begin to reduce significantly!

You can use the checklist below for a reference on each mission’s Par Score:

  • Tayari Plaza - 8,000 Points
  • Uplift Reserve – 14,000 Points
  • Kizingo Boulevard – 18,000 Points
  • ONI Alpha Site – 16,000 Points
  • NMPD HQ – 40,000 Points
  • Kikowani Station – 42,000 Points
  • Data Hive – 8,000 Points
  • Coastal Highway – 90,000 Points

Once you beat the Par Score for all eight missions, this achievement will unlock.

D20
H3: ODST: Complete Coastal Highway on 4-player Legendary co-op, with Iron, and no 'Hog or Scorpion.    (79) 

As a pesky reoccurring achievement, most of you should be familiar with the requirements in getting this done. First, you must activate the Iron skull in the Campaign lobby and begin the eighth mission of the game, Coastal Highway, from its beginning; you cannot start at a different Rally Point. 

With the Iron skull activated, any death will revert all players back to their latest checkpoint. As for getting down the entire highway without a Warthog or Scorpion, it must be known that the first service tunnel on the highway contains 2 Mongooses and 4 Rocket Launchers with 999 ammo each. From here, each player should grab a Rocket Launcher and pair up on a Mongoose, then proceed through the highway segments as you regularly would. 

For additional tips on this achievement, refer below:

  • All four players should communicate via headsets; communication is vital in order to prevent deaths throughout the mission, especially since players are heavily exposed on Mongooses
  • When driving the Mongooses down the highway, avoid getting in the path of Dare and always try to take out Covenant vehicles before focusing your attention of ground units
  • Each “gate checkpoint” contains two health kits, so utilize them wisely
  • If all four players enter each “gate checkpoint” at the same time and wait for 5-10 seconds before following Dare out, you should always force/trigger a checkpoint

With clear communication and steadfast dedication, you and your team should have no problem pulling this off. The vast amount of Rocket Launcher ammunition is even key to finishing the final firefight of the mission with ease. As soon as the friendly Covenant Phantom swoops in to pick up the group, the ending cut scene will ensue and the achievement will unlock for all four players in the game.

Do You Remember When We Met5
H3: ODST: Play a game of Halo 3: ODST on the 22nd of any month.    (4) 

As a means of celebrating the launch date of the original Halo 3: ODST, this achievement simply tasks you to play the aforementioned game on the 22nd of any month. This can be done by playing any of the Campaign missions, be it the Mombasa Streets or NMPD HQ. Overall, this achievement is pretty straightforward and can be obtained with minimal effort of your part.

Safety Not Guaranteed30
H3: ODST: Complete a Halo 3: ODST LASO Campaign playlist.   (45) 

As with any of the playlists dedicated to the Halo 3: ODST Campaign, the (shorter of the two) LASO Campaign playlist will task players in completing all eight missions on the Legendary difficulty with all skulls on. Take note however that the developer has selected a preset number of skulls for this Campaign, so all the skull modifiers aren’t technically activated. With that said, this achievement can be earned in either Solo or Co-Op play. 

What’s more, it’s important to remember that only scoring skulls will be activated. These generally reward players with higher score multipliers and bonuses to base enemy values (for Par Score achievements). Non-scoring skulls on the other hand are sometimes neutral, such as Grunt Birthday Party. Below, you can get a glimpse of all the skulls that will be activated in the Halo 3: ODST LASO Campaign playlist.

  • Black Eye - Your shields only recharge when you melee enemies. Bash your way to better health!
  • Blind - HUD and weapon do not display onscreen.
  • Catch - Enemies throw and drop more grenades.
  • Cowbell - Acceleration from explosions is increased.
  • Famine - Weapons dropped by AI have half the ammo they normally would. You might want to pack an extra magazine.
  • Grunt Birthday Party – Grunt head shots lead to glorious celebrations.
  • Iron - Death carries a heavy price. Dying in co-op resets you at your last saved checkpoint. Dying solo restarts the level.
  • IWHBYD - Rare combat dialogue becomes more common.
  • Mythic - Enemies have increased health.
  • Thunderstorm – Upgrades the rank of most enemies.
  • Tilt – Enemy resistances and weaknesses are increased.
  • Tough Luck – Enemies always go berserk, always dive out of the way, never flee.

As a few general tips, keep the following suggestions in mind when tackling this achievement. First, take combat slowly and try picking off enemies from afar with short controlled bursts of medium-ranged weapons like the UNSC Pistol or Covenant Carbine. Since your HUD and weapon will not appear on screen, it may take some time in getting used to the “blinded” touch. Also, choose your shots wisely and always aim for vulnerable weak spots since ammo is scarce on the battlefield and enemies will have increased health and resistances. Second, since deaths will revert your progress to the mission-start, it’s highly recommended to attempt this achievement in Co-Op play. Lastly, enemies are going to be agile in combat, diving away from your shots and throwing a lot of grenades, so don’t forget the basics of cover, and when necessary, close-quarters combat, especially since shields will only recharge upon melee attacks. 

Here are a couple other tips to keep in mind:

  • Towards the end of Tayari Plaza, make sure to eliminate all the Jackal Snipers and as many Brutes as possible; when the Hunters begin to storm the streets, don’t stop to kill them…rush towards the end of the mission
  • On Uplift Reserve, use a Warthog to quickly drive past the first battlefield until you reach an isolated Ghost; grab this Ghost and try rushing through the rest of the mission as if you were going for the “Classic” achievement
  • On Kizingo Boulevard, it would wise to learn how to get at least 1 or 2 Scorpion Tanks over the barriers where Dutch is located as a means of having powerful vehicular firepower in the final battle
  • During the interior fight of Oni Alpha Site, make sure to give Mickey a Rocket Launcher since he’s invincible and will have unlimited ammunition
  • For NMPD HQ and Kikowani Station, it would be in your best interest to learn a Legendary speedrun of both missions as a means of bypassing fights that aren’t necessary to take part in
  • On Data Hive, always keep a Noob-Combo on hand (for Brutes) and make sure to use VISR Mode often, especially in the darker corridors; make sure you grab a Covenant Carbine (for the Drones) when venturing into the Hive with Dare
  • Once you reach the highway on Coastal Highway, grab a Fuel Rod Cannon from a dead Grunt and give it to Buck; make sure he rides passenger until you get a Gauss Hog, at which point he should ride the turret of this vehicle

Overall, with enough persistence and skill, the Halo 3: ODST LASO Campaign playlist shouldn’t be too time consuming if you group up with a competent party and make use of the various tips mentioned above coupled with scattered video guides online. Just take the missions slowly and once the Epilogue cut scene has concluded, the achievement will unlock.

Trifecta20
H3: ODST: Complete three Halo 3: ODST playlists.   (2) 

Like before, these predetermined Campaign playlists act as a means of experiencing a particular set missions that all share a common thread. Hand-crafted by the developer, some of these playlists are unique, such as all the vehicle-related missions. There's also playlists for Easy Campaign, Normal Campaign, Heroic Campaign, Legendary Campaign, and LASO Campaign.

Since the LASO Campaign playlist (Non Stop Action) must be completed for a separate achievement, all that is required is to complete a minimum of two other playlists for this achievement. In Halo 3: ODST, the two shortest playlists - which also prove to be quite enjoyable - are the following:

  • Vehicle Rally - Uplift Reserve, Kizingo Boulevard, Kikowani Station
  • Arena Battles - ONI Alpha Site, Coastal Highway

Simply pick and choose whichever three Campaign playlists you'd like to work on and once they have all been successfully completed, this achievement will be yours.

Nagato Makes Moving Easy30
H3: ODST: Complete all Halo 3: ODST Legendary campaign missions in under 3 hours.    (12) 

It's worth noting that you may want to grab two or three Co-Op partners when working on this achievement for two reasons. One, the extra firepower will help put down enemy forces a little quicker. Secondly, one or two players can usually act as a decent distraction while the remaining two players attempt to push on and run by as many enemies as possible in an attempt to grab the next checkpoint (on certain occasions). 

This essentially means that you may want to replay individual missions dozens of times in order to perfect your runs and learn combat tactics. Additionally, this achievement does not need to be attempted in one continuous run. Rather, the game will track your best time on each mission completed on the Legendary difficulty setting and add them up for a grand total. When a new "Personal Record" is set for that mission, it will override the previous tracked time. This means that you can tackle a mission multiple times in an attempt to perfect your speed run. 

Halo 3: ODST’s Campaign missions are generally short and aren’t too hard compared to other games in the series, so at times, even a semi-casual playthrough of the Campaign on Legendary will net this achievement without much thought or skill. Also, take note that the various segments of the New Mombasa Streets do not add time to the counter, so you can take all the time you desire exploring for audio logs and clues.

One Got Away10
H3: ODST: View the missing link.   (10) 

This Easter Egg can be found in the Epilogue. 

During the Epilogue’s cut scene, Sergeant Johnson and Dare will begin talking about ONI and the Engineers. Then, Johnson will sit down with the Engineer that was extracted during Coastal Highway and hand the alien a cigarette lighter. While this happens, pull left on both analog sticks and the camera should pan left to a frame of Buck awkwardly touching a caveman, similar to the those found in Halo 3’s “Sierra 117” mission. The achievement will unlock once you’ve spotted this strange frame and the cut scene concludes.

Like a Broken Record10
H3: ODST: Find a legendary hidden music cue.   (5) 

As soon as the mission starts, grab a Banshee on the platform off to the far left and proceed through the mission as normal; waiting for your allies to board the Phantom, opening the first gate, and passing through the service tunnel until you reach the second outdoor area of the mission. At this point, steer your Banshee towards the right, where you can see a bright screen that says “CONNECTION LOST.” Pilot the vehicle towards this screen you should see a small bridge with an alcove/platform on each side above the structure. You’ll need to exit your Banshee on the right-hand platform. If you wait on this platform long enough, a familiar tune will begin to play and your achievement will unlock.

Vandalized10
H3: ODST: Face it.   (8) 

This Easter Egg can be found in NMPD HQ. 

At the start of the mission, proceed through the doors with Buck and into the first rooftop section. If you’re playing on a lower difficulty setting, which is advised, simply run past all the enemies in this area and make your way to the doors on the far end of the rooftop. Move through these doors, climbing the stairs on your right so that you’re on a small balcony. Continue moving forward until you reach the end of the balcony. 

At this point, turn your character 180 degrees, then jump backwards off the balcony. As you are falling you should see a hand-drawn face on the side of the building you were just standing on. All it takes is looking at the drawn face for about one second and the achievement should unlock right away. If this text sounds a little too confusing, please refer to the video guide below for a visual representation of how this can be achieved. Please take note that this cannot be done in Co-Op play. 

Saturday Morning Cartoon10
H3: ODST: Is there a toy inside?   (9) 

This Easter Egg can be found in New Mombasa Streets (preferably at the Campaign’s start). 

At the start of the game, proceed through the mission as normal until you have to activate the Superintendent. After this occurs, you’ll receive a waypoint on your HUD, instructing you to enter a nearby building in order to pass into another section of the city. Make your way through this building and before exiting the door that leads to a courtyard of sleeping Grunts, stop before door and check the right side of the room. You should see a small couch and an even smaller box of cereal on the ground towards the far end of couch (it’s not that hard to see). Walk up to the cereal box and stare it for a few seconds, then the achievement should unlock.

Classic20
H3: ODST: Finish any level solo on Legendary, with no shots fired or grenades thrown.    (15) 

This achievement is best done on Uplift Reserve. As soon as the mission begins, heads towards the objective, up the dirt path where you’ll see a group of Marines taking fire in the distance. There’s an overturned Warthog near your allies, so approach the vehicle, flip it, get in, and begin driving past all the enemy forces and Covenant opposition (Choppers and Wraiths) towards your next objective. 

As you squeeze through a tight canyon past two Wraiths and a Chopper, you’ll receive a checkpoint and spot a Covenant Ghost. Transfer out of the Warthog into this Ghost and now it’s up to you to reach the end of the mission using the Ghost to bypass all the firefights and enemies along the path. Take note that you are able to hold the left trigger to activate the Ghost’s boost but you cannot, under no circumstance, hold the right trigger to fire the vehicle’s weapons; if you do, it will void the achievement. 

For the sake of avoiding convoluted text in describing the route to be taken one you have possession of the Ghost, feel free to refer to the video below as a visual representation of how to complete the mission without firing a shot or throwing any grenades. Thanks for the video footage, Maka!

Catch 'Em Napping10
H3: ODST: Kill 5 sleeping Grunts on Mombasa Streets.   (4) 

After competing ONI Alpha Site (through a mission select via the Campaign lobby), you will return to the Mombasa Streets and like always, be required to explore the city in order to find the next clue. When you regain control of your character, head over to the left side of the street, through the gate that you originally came from when finding ONI Alpha Site’s mission clue. Past the gate, you will encounter 5-6 sleeping Grunts and a Brute (they won't spawn here outside of mission select because during a natural playthrough, you would have already killed them coming to ONI Alpha Site's clue). 

The first two Grunts are separated from the group and can be smacked for a one-hit kill. As you walk up the street, you’ll be able to smack another sleeping Grunt, but this tends to alert the Brute and wake up the remaining Grunts in the area. Since you’ll already have three kills towards this achievement by now, simply revert your checkpoint and repeat the same method and the achievement will unlock once the fifth sleeping Grunt has been killed via a melee attack.

Strong, Silent Type10
H3: ODST: Assassinate 3 Brutes in a row on Data Hive.   (7) 

During Data Hive, as you proceed further down into the sublevels of the station, you will begin to engage Brutes frequently throughout the tight corridors. For the purposes of this achievement, it must be stated that “in a row” is very strict; you cannot get any kills in between Brute assassinations or it will revert progress towards the achievement. 

With that in mind, this achievement isn’t too hard to grab regardless. Whether you’re playing on a lower difficulty or even Legendary, and whether you’re playing solo or with a group of players, simply wait until you reach a corridor where you can visibly count and see three or more Brutes. Once you know there are at least three Brutes in the area, get close to one so that he lunges for a melee attack. Side step their swing and try smacking them in the back quickly. If done correctly, it will be a one-hit kill. Now proceed to do this on two more Brutes and remember, any other type of kill on a Brute, or any other kill on a different enemy type in between the assassinations will revert progress made towards this achievement!

For a slightly alternate method that utilizes beginning this mission at Rally Point Echo, don't hesitate in checking out the video below, courtesy of Maka.

Bip! Bap! BAM!10
H3: ODST: Earn a Triple Kill medal with the pistol on any level.   (4) 

This achievement may come naturally to most players during their playthrough of the Campaign. Generally, despite the difficulty one is playing on, Tayari Plaza will most likely be the mission that allows for the easiest lineup for head shots on Grunts as you pass through the city streets towards your objective. If needed, you can always turn on the “Competitive Scoring” HUD in the Campaign lobby so that you’ll know exactly when you’ve scored a Triple Kill (it will be indicated by the medal). Just wait until a few Grunts are near each other, then use your Pistol for some quick and easy head shots.

Pineapple Express10
H3: ODST: Kill 4 enemies with a single plasma or frag grenade.   (8) 

This achievement is best done on a lower difficulty and can be obtained in about any mission where there is a Phantom Drop ship. This is mainly due to the reason that as these Phantoms arrive, they will drop groups of Covenant onto the battlefield, usually all clustered together. If you’re attentive and watching the Covenant units drop out of the Phantom, you’ll be able to quickly lob a Plasma Grenade at one enemy in the group and the explosion should kill all the Covenant that dropped. 

Generally, the outdoor firefight segment of ONI Alpha Site or the escort segment towards the end of Data Hive work best for this achievement. If needed, you can always turn on the “Competitive Scoring” HUD in the Campaign lobby so that you’ll know exactly when you’ve killed four enemies with a single grenade (it will be indicated by an overkill medal).

Fowl Hunt10
H3: ODST: Kill 3 Jetpack Brutes with a shotgun on Oni Alpha Site.   (5) 

This achievement can be obtained towards the end of Oni Alpha Site and is best done when playing on a lower difficulty (thus making the Brutes easier to kill). Once you reach the interior of the ONI Building, one of your Marine allies will almost always wield a Shotgun. At this point, swap one of your weapons out for their Shotgun and hold onto it (and don’t expend too much ammo) for the duration of the interior firefights. 

Once the initial waves of Covenant are dealt with and you’re required to take the elevator up to the roof of the building, you’ll be greeted by a Brute Chieftain and about 4-5 Jetpack Brutes. Make haste and dispose of at least three of these Brutes with your Shotgun (usually 2-3 blasts will kill them) and the achievement will be yours.

Does Whatever a Spartan Can?10
H3: ODST: Destroy a Wraith   (7) 

This can be obtained on Kizingo Boulevard on the Easy difficulty setting. As soon as the mission begins, turn around immediately and you should see a Wraith alongside two Jackals ambushing your position. Since you’re playing on the lowest difficulty, you’ll be able to run right up to the Wraith and board it from either the front or back. Once you’re in the animation of hijacking the Covenant vehicle, use your melee attacks to destroy the Wraith in just 4-5 punches and unlock the achievement with ease.

Firefly10
H3: ODST: Kill a Drone with a flame grenade on Data Hive.   (6) 

During Data Hive, you will eventually reach a corridor with Active Camo’d Brutes. Upon killing these Brutes, they will usually drop 1-2 flame grenades. Make sure to pick these grenades up and proceed through the mission as normal. You’ll will eventually encounter a decent amount of Drones, be it in subsequent corridors along the sublevel or later in the mission when you pass through the Hives with Dare. Despite your preference on where to obtain this achievement, simply wait until a Drone has landed on the ground, dropping their defense, and then lob a flame grenade at the creature. The blast will kill the Drone almost instantaneously and the achievement will be yours.

"BLAM" Said The Lady!10
H3: ODST: Swap Dare's pistol for a Rocket Launcher on Coastal Highway.   (7) 

This achievement can be obtained at the beginning of the aforementioned mission. When you reach the open courtyard fight against Brutes, Jackals, and Grunts, you’ll need to locate the UNSC weapon cache on the left-hand side of the courtyard; it’s tucked away underneath a small awning with red lights. Once you’ve picked up the Rocket Launcher here, proceed to the objective and wait until you reach the section where Virgil need to pry open the elevator doors. This will take a while, so use the time to swap out Dare’s Pistol with the Rocket Launcher you picked up earlier.
