I loved the first Killing Floor and I love Killing Floor 2. If you're a fan of the first, or even just wave/horde shooters, then you'll enjoy this.

Bare in mind, the game is currently in Early Access, but even what's out now is worth the 30 dollars. Normally I would suggest waiting for games to leave EA, Tripwire is a trustworthy enough company, and this is a good enough game, for me to strongly recommend it. With the classes, maps, and characters that the devs have promised, I expect this game to go down as a PC classic, just like its predecessor.

9/10, with the potential for 10/10 by the time it's completed.

Perfect for a group of friends looking for a cheap but fun game. It has good replay value and fun co-op. Sometimes it can't handle a full multiplayer match though (the only problem I've faced).

It's 6.5/10. Solid multiplayer (when it doesn't crash) and totally worth the 2 dollars I spent on it.

The gameplay is great. The powers are fun to use, especially quad-wielding and executions. Unfortunately, the campaign is far too short and the ending is frustrating. Also the multiplayer is kind of weak. If it's on sale I recommend it, especially if you're a fan of the first game.
