Well it's about damned time.
It seems like they have WAY more money and experience this time around too, I'm interested to see how exactly KF2 turns out.
Killing Floor had great shooting mechanics but multiplayer usually turned into a camp fest, simply due to map design and the movement speed of non berserkers. Also, competition for kills more than teamwork was usually the method of operation on most pubs, hopefully Tripwire can fix that this time around.
Unless the gameplay videos look like complete shit I'm required to buy this game.
