Killing Floor is an old co-op FPS zombies game where you have to go through waves of zombies with different classes in different maps and on different difficulties. I understand why people love this game, especially being one of the first in its genre, but I personally have not enjoyed it a lot, and I believe that there are many better co-op zombie games out there. It is pretty outdated in my opinion. The gameplay in general is quite repetitive even though there is a variety of classes, maps, and difficulties. In addition, the sound effects, and the slow motion are a bit annoying. 5/10.

good game
