When I first started up Killing Floor 2 I had no idea what to expect. The game looked like a very grim, zombie-killing game. What it actually was - a ridiculously impressive and immersive strategy game… that was very grim. There are a few technicalities, but overall there is nothing out there that gives you such a feeling of fight-or-flight – while at the same time – giving you a giant adrenaline rush from decimating mass amounts of baddies. And I can tell you after some 25 hours… it doesn't go away.
