This...game....is....amazing!
(I know I don't really have any playtime on Steam, but I've played a lot on PlayStation.)
Just boot up KF2 and slay either 4, 7 or 10 waves of "zombie like creatures" (I know their Zeds, but yah know... review for new players) if you survive these waves you will fight one of several bosses.
You can play either solo, with friends or online with randoms, but no matter what you choose the matches will always be great fun!

Are you a fan of Metal music? No?.... Doesn't matter... you will be after you play this game.
I didn't like metal either, but after you slice these Zeds in half or blow them to bits whilst metal is just blasting.. you will enjoy it a lot. It is really satisfying.

This game has great melee combat, gunplay and animations since you occationally enter "Zed time" (slow motion) all the animations in this game are super clean & sleak.

I highly recommend this game, great fun.
TY Tripwire and nowadays Saber Interactive for this amazing game! <3
