I completed Halo 2 anniversary on Normal and did not get the achievements for completing it. I also played it seeing it in both remastered and original. Please help.
The exact same thing happened to me, I’m now going through the campaign again go see if it will unlock afterwards.
I also have the problem with completing Halo 2 on Normal did not unlock. In reviewing the locked achievements, I see that the achievements for two mission did not unlock- Regret and Upgrising. I’m playing the Master Chief Saga playlist so I need some assistance with this problem. My playlist status shows mission 26 - Halo3:Arrival - next but the status of missions in the playlist shows 23 out of 45. I hope this is a bug that can be fixed with a patch because I don’t see any way to get those two missions unlocked without starting the playlist at mission 1. And I’m not going to do that…I’ve hit my limit of Halo:CE playthroughs.
