I don't think there's any Deathmatch or anything like that.. its more like Killingfloor and L4D. It seems like these 4 player co-op games are becoming pretty popular, and it's not even a detriment to code hacks for them even though you're only headshotting at AI. You get perks, upgrades and all that stuff. In a way co-op can be competitive and you can hack it to get an edge and stay alive even if your teammates can't cope.
