It won’t let me log on here so my gamer name is TomsGamin22… I’ve been doing all the achievements for ages now ans I had one left called ‘prison break’. Me and my brother ibeanie played this together on co-op campaign and he got the achievement for simultaneously killing tow wardens on heroic on the 14th mission but I got nothing… Why is this? This achievement took me ages and it’s my last one to get.
This happend to me in battlefield 1 and i just reset my xbox and that worked.
but that was battlefield 1 and i don’t know if it will work with halo 5.
