Killing Floor 3 is a cooperative and solo action horror first-person shooter developed and published by Tripwire Interactive. It is priced at .99 in the U.S. and £34.99 in the U.K. Players combat waves of bioengineered monsters called "zeds" using various weapons, with matches consisting of five waves followed by a boss fight. Players can replenish ammo and health and upgrade weapons between rounds. The game features a new gore system called M.E.A.T., allowing for dismemberment of enemies. There are six unique strategists with distinct skills, and team composition is important for multiplayer sessions. Difficulty levels include Normal, Hard, and 'Hell on Earth,' each offering varying challenges. Progression can slow down after ten hours, and optional story missions provide around four hours of content. Tripwire has announced plans for post-launch content, including new weapons, mods, maps, zeds, and characters.
