So i have completed the campaign on legendary but in waypoint it says i have only completed 3 missions even though i have all the achievements. Does anyone know how to correct this?
NO idea but mine is to opposite. I have completed to game according to Waypoint but I never got the Mission 8 achievement or the Wake up John achievement.
go back and play those level again while logged into xbox live and it will register, i did mine offline and had to go back and re do the levels that didn't get synced with waypoint
