Halo: The Master Chief Collection Achievements


Devastating

Halo 3: Complete all Halo 3 Legendary campaign missions in under 3 hours.   

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. 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 3'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 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.

Also willing to create a good group to do the multiplayer achievements, and these Speedrun (legendary is already difficult.. so as many people as we can get will be nice),

Add me, invite me to your party and lets play

You don't have to complete all the missions in a single run through!

If someone wants to do this let me know, I feel it should be very easy with 4 player co-op, I've watched the world record speed run of halo 3 and there aren't too many hard skips and it has a lot of extra time to be under 3 hours. I've also already gotten the speed run for halo 4 legendary achievement.

All my solo times add to less than 3 hours, and with co-op thrown in it gets even less. Is there anything I can try to get this to unlock?
