Sadly there is not, really. You have a singleplayer series of missions in the multiplayer maps of basically rehearing objectives for multiplayer, and PVP where enemies try to get in the way of both teams. I managed to make my own sort of PVE co-op by going into a private match with my brother and just killing enemies to our hearts content, which is fun, but you need to have someone you can go into a private game with and avoid accidentally killing each other. Hope my info helps.

anything like this to clear maps of zombies or infestations working together as a team?

No, if you're looking for that sort of game there are far better options out there such as Left 4 Dead and Killing Floor, the only thing this game has is a bad single player campaign, multiplayer is completely dead so I wouldn't count that at all.

Thanks for the information. Does sound fun as Cavou said and think they really missed the boat there with not having that option and making it just one type of gameplay. Sad when that happens since any game that offers only one type can get old after awhile. :P

Seems always a fun playstyle when people can work together instead of against eachother especially in a zombie game.

operation raccoon city would be awesome for co-op!
