The Rules Have Changed Since Killing Floor

Saw it in a steam update after having never heard of it. Heard "The rules have changed" in the trailer and figured I'd post here.

Looks like a bloodier(read:more fun) Killing Floor. Comes with mod support so it'll likely last a while.

I'm thinking of getting a four pack but I'd need people to play it with.

i have the game, none of the expansions though.

Says on the steam page that DLC is free.

I just got it, it seems fun enough. Infinitely better with friends.
