I have completed the campaign on Legendary and cooperatively and have not received any of the achievements. I can’t get the master chief helmet and I like to rack up gamerscore and thats 150 points I don’t have. Even on waypoint it says I have completed everything, the only thing I noticed was that when choosing the mission midnight on campaign it says its incomplete. I have redone it on legendary with my friends multiple times and it still isn’t working… Someone please help me its very upsetting.
ps
If anyone knows if there is any way to reach someone at 343 industries or xbox that could fix this problem that also would be appreciated
