Hey guy's me and a couple of my buddies keep playing co-op campaign on hardest difficulty but when one of our friends can't play we'd much rather prefer others don't join, because usually they hinder the team more than help it. I'm not trying to be a jerk when I say that so if i offended anyone, I'm sorry. But my question is, is there a way to password protect a co-op campaign game? Thank you for any information in advance!
