In what I can only describe as a monsters v.s humans type of affair, you play as one of a handful of characters who enter brilliantly designed battlefields to face a horde of zombie like abominations. You fight these battles in waves, a nice touch in my opinion, which gives you a short amount of time to build up your arms and re stock ammo. A full on co-op only game means you could be with five other players or all on you lonesome (a situation you REALLY don't want to find yourself in TRUST ME!). The other players I have been playing alongside have been very great to play alongside and the sharing ammo and cash makes this a game of teamwork and not a one stands alone type of game like COD plays like. The weapon choice is wide and the costume designs are fun and post-apocalyptic, while the class choices means that your team can be very well balanced if you play it right.
Killing Floor 2 is a bloody good game, a hell of a lot of blood soaked zombie/demon killing fun which literally kept me personally playing none stop for hours at a time. A definite buy if you are a fan of online gaming or if you are a total novice. The controls are simple, the creatures are brutally violent the longer the waves go and this makes for gripping gaming.
