I thought it was going to be free roam or some thing its annoying that your stuck in you little corner. You could have just added coop to zombies. I just find a little dissapointing I know you can do better but I think you guys just hot money signs in your eyes after BBR and now you dont care about the game anymore If you want a coop shooter then just make some thing like cod black ops zombies. (not the iOS version) where you get to move. So maybe consider doing something like that next time you release a game, or a battle bear 2 or something.
