Player vs. Player?

I would get much enjoyment from seeing some kind of Player vs. Player setting in the game whether it be with A squad of players vs. a squad of specimen (e.g where the Specimen squad get given random specimen upon each death) or some other kind of format, generally i think it would add a bit of competitive play and could be all around very entertaining to be a part of especially if done in a large group of friends. I cannot begin to tell you how many times me and a large group of friends have wanted to play Killing Floor 1 together, but couldn't because all the good original servers are only big enough for 6 players meaning we had to switch between who we would play with leaving some people out of all the specimen killing fun!
