Halo 2 in 3 hours not working

I beat it in 3 hours with time to spare and it wont give it to me and on your site 2 levels wont save my times no matter how much i do them.

I checked your times on waypoint and it looks like you cleared the game under a hour. Check the in game leaderboards and see your times.


If you’ve completed it under 3 hrs, give it a day. If it still doesn’t pop, hard reset and delete all save data for MCC. Load and sync the achievement should pop.
