You can't play co-op offline unfortunately. Only online. What do you have friends that actually go to your house? That's blasphemy! You should be connected online, only playing with people online, and buying everything digitally! You should also not buy used games or complain about online passes. You are to buy every Call of Duty game ever made and then complain about how Dynasty Warriors is repetitive. That is your job as a hardcore gamer, don't forget it!
