Guys what about the coop mod????Should there be one?I saw a guy working at it.im downloading now that is supposed to be campaign coop.shouldn´t you guys be working at it too????

I am sorry to say that in a four+ year old game, a mod as ambitious as that will not be done. There is a somewhat buggy Co-op mode but it does work to an extent. The problem is that it will corrupt the game from being played normally.
