Halo 2: Complete the LASO campaign playlist.   

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.

Today, about an hour ago me and my cousin finished Halo 2 on LASO, ALL skulls on. This being The un-named one in Armory, Thunderstorm, Blind, IWHBYD, Catch, GBP, Famine, Envy, Assassins, Mythic, Sputnik, Angry, Ghost, Iron (Although ofc it did nothing) and Black Eye.

Defo the hardest mission by far was the first. I think total there is about 70 ish Ultra Elites we have to kill with no power weapons, they take two plasma pistol blasts to knock their shields down, half ammo on the map, theyre PERMANENTLY invisible so PP doesn't lock on and black eye just makes the mission a misery. But we found the game go easier after that :)

So GOOD LUCK! We can't wait to do it again :)

And if anyones wondering how long it took? Sorry we don't know, but we made 14 'Player Profiles' on the game, on

No idea how to send messages to non-friends, so send a message to me if you want to do LASO. I'd start on Cairo Station and move progressively from there.

Judging by the skull selection, it looks nearly impossible. Are we allowed to use non-scoring skulls?

Comment #18 by Decrepit Angel
Saturday, December 27, 2014 @ 08:30:28 AM

So as it stands LASO isn't too bad but it definitely needs the "Envy" skull. Cairo station is a nightmare but it gets easier afterwards. However, Gravemind appears to be impossible. The lift taking you to the jail cell section at the bottom is impossible because of the "That's Just Wrong" skull automatically alerting everything which gets you killed, even with double overshields, before you even leave the lift. I'm planning on experimenting with having both players in coop using a brute shot to try to knock some of the enemies off of the ledge on the way down but it is very likely that it will be unobtainable until Envy is added. My recommendation if 343 happens to read this is to have Envy negate the time on the leaderboard but be something like a 0.25 multiplier for score instead of a 0.

Comment #19 by Decrepit Angel
Saturday, December 27, 2014 @ 08:31:29 AM

00 so it can still be used in the playlist. Until then, expect to be stuck on Gravemind if you go for this achievement.

If you start a coop with someone with the last level, them hosting and have them save and quit at the start, your laso playlist will now be at the last level. Then you just have to beat it solo or coop while hosting and youll get the achievement.

Wednesday, January 07, 2015 @ 01:56:51 AM

/ up for doing this for sure, if anyone has the last checkpoint i'd help with whatever else achievements you need considering this one is pretty awful.

I don't know entirely if the host had to have gotten to the last level prior to this on LASO or just start the level on a regular game and quit, but i'd be willing to help out still either way for these, let me know if interested please

I'm looking for at least one person to help me with the last misson on LASO. That's all I have to do (and halo 1 last mission). Can't do it by myself as if I die it restarts the mission but in co-op it restarts from last checkpoint. Players that help me should get the achievement as well without having to play the whole playlist. Add me with a message so I know you want to help. My GT is: King Gaz III
