Sometimes, all a game needs to do is hand players a gun and let them go to town on zombies. It's a classic experience in the gaming industry for a reason, and Killing Floor (and its Zeds) has always been synonymous with this concept. 20 years after Killing Floor was originally released as an Unreal Tournament 2004 mod, its threequel is preparing to bring its frenetic, chaotic gameplay into the modern era. Killing Floor 3 officially releases on March 25, and Game Recently spent a few hours killing Zeds in it.
