V4ntom, probably not I'm afraid, Got Kreeeee, Wingzero, Miss K and myself (more or less confirmed), with Alrik and Cadman in reserve already. (I'm a popular chap)
I don't want to play Co-op with anyone, I will be going through it on my own as I always do. It would get on my nerves if I am trying to play properly just to have you all trying to team kill each other through out the whole thing, while I'm trying to pay attention to whats going on.
Only time I will do Co-op is to get the achievements for it (if there are any) or to help people out if they can't find an extra person.

This is due out on the 22nd correct?
Actually it makes no mention of a full 4 player co-op game. Hope it has one.
I'm not coming over if there's no campaign coop!

Why isn't firefight on the multiplayer disc?
