Hi there I have completed halo 2 mcc on legendary and havnt received the achievement also non of the mission achievements how do I fix this thankyou
Were you playing while offline?
I had a look at your service record on Waypoint and it looks like the game did not record any of your level completions. As mentioned above, you need to be connected to Live so your results are uploaded to Waypoint. Once all your completions are saved to Waypoint, you will receive your achievement. As far as I’m aware, playing offline will not allow you to unlock the Legendary completion achievements.
^^^Ditto
Why so serious achievement is not working why not?!
Plz help it’s one of my last achievements
