Keyes

To unlock this achievement you must finish the mission Keyes which is the 9th mission in Halo: CE . If you run through the game from beginning to end you will unlock this achievement because it isn't missable.

Note: The mission achievements have been really bugged so if your achievement says "Done.... Unlocking" your in the same boat as basically every gamer. I still have 1 mission achievement unlocked a week and a half ago and it still says "Done.... Unlocking" don't keep attempting to unlock it because it won't happen. Just pray Microsoft or 343 (whoever has to fix this will) which with the amount of people its affecting, I can assure you something will be done.

Update 12/09/2014: Seems as though they fixed all level achievements, either it will unlock on you randomly (some say) or you can definitely unlock it by replaying the level. It won't unlock immediately, but at a random time, most likely you will have it in 24 hours.
sparks183Do having any skulls on effect this?

Strategy OneI believe any skulls with a 0 multiplier will prevent it from unlocking. I cannot say for sure, but I would recommend not using 0 multiplier skulls because they take most achievements away although there are some you can still get (terminals, Skulls, collectibles basically.

AmortisI’ve got problems with this achievement too for a long time. But it seems they fix it with the new MCC. After playing this mission again after the cutscene the achievement pops up. Thanks 343!
