I had this pop no problem playing through for the first time in co-op.Posted by thefrozeneskimo on 19 Jul 17 at 01:44 I started playing this game to help a friend do the co-op cheive. I got all the individual level completion cheives along the way but not the complete game or the co-op one. Do I need to play this crap game again to unlock both of these??Posted by Beam147 on 14 Oct 17 at 22:10 Leave a comment
