The Killing Floor series of horror-themed first-person shooters has been around for a long time. The first game was a bit rough looking but fun. Killing Floor 2 then came along and looked like the first game but better. Now, Killing Floor 3 is in the works, and it looks like the second game but better. We know this for sure because the new game's first gameplay trailer has just debuted. Yes, it looks like the previous game, but also incredibly fun!
