I played most of the campaign with a friend on online co-op, but I remember playing a little part without my friend on co-op. So I still haven't unlocked the "Friends with Benefits" achievement. Is there anyway I can check to see which chapters I haven't played in online co-op?
Friends With Benefits Achievement.?
