I’m going through the campaign with my brother to pick up some of the co-op achievements I’m missing but some of the achievements don’t seem to want to unlock. We went through Swords of Sanghelios with both mantises intact and in use the whole time on legendary and the achievement didn’t unlock. We then attempted the emergency boarding procedures achievement after that with me riding on his phaeton to safety and that achievement didn’t unlock either. Are these achievements just bugged?
Xbox Live has problems with achievements at the moment.
Also seeing a similar issue.
I should have popped Heroic completion, heroic co-op and finding a skull the other day but none unlocked. Some mission specific ones did, in the same session.
Any ideas?
Cant get all skulls achievement to pop. Tried going back to get one. Still no luck.

I recommend submitting a Halo Support ticket for this.
