CE and Halo 2 campaign achievements not unlocked

Games Halo: The Master Chief Collection
1

Hi everyone,

We played Halo CE MCC Campaign (Steam) in Heroic coop with a friend, and no achievements has been unlocked after the completion of the 343 Guilty Spark. It’s sad because we finished the campaign, but never unlocked achievements, and in my home screen, my game said that I have finished 10/10 missions in Halo CE (in Heroic coop).
After that, we also started Halo 2 campaign with the same friend, and he unlocked completion achievements for Cairo Station and Outskirts in coop heroic, and me nothing at all. BUT, this time, for Halo 2 I’m at 0/10 (he was the host).

I submit a ticket 23 days ago, and still no answer from Halo Support. But do you guys have workaround to be able to unlock achievements and have my progression properly saved?

Thanks :slight_smile:

According to your Service Record, the game didn’t register your completion of Two Betrayals, Keyes, and The Maw for Halo: Combat Evolved. Completing those missions again will get you the achievement.

Yeah, why the completion is set as completed and the achievements are not unlocked?

And the most important: Why as client, Halo 2 campaign completion is not working at all?

Quick Update: We redo (for the third time) Two Betrayals in Heroic coop and still no achievement. What happens?
