who knows...even if it dos come out wont be for a while and i dont see why there needs to be a new separate game theres doesnt seem to be big differences besised new characters/weapons if anything they should just make it a add-on
As for L4D 3, has there been an announcement or something? I think the second one was good, but it was too rushed. If they do make a third one I hope they spend a little more time on it.
For L4D3, I really hope that the campaign is extended, because it seems really short. Also, it would be nice to see some machine guns, like an M60 or RPD.
