I been Playing Halo: The Master Chief Collection. Me and a Friend had beat both Halo CE and Halo 2. Within Halo CE and 2 we beat it on Legandary. In the Game NamePlate it said that I have to beat on Easy on all the games. Well I did it on Halo 2 but did not get the NamePlate. For Halo CE from Halo Mission to THE MAW, I did not get my Achievements. When I looked these Achievements I found that I should have got them when I was CO-OP with my friend. But Sadly no. HOW can get these Achievements / Nameplate when you 343 or Halo waypoint don’t ok of me getting them done? Please let me know why this has happen? My Gamer Tag is SnakeEyesBP1980
