Compare Killing Floor prices across trusted key stores and find the best deal. Developed by Tripwire Interactive. Published by Tripwire Interactive. Released on 5/14/2009. Available on PC. Genres: Action. Metacritic score: 72/100.

A 2009 wave-based shooter where six players gun down grotesque monsters in industrial maps, janky by modern standards, but co-op survival done right before it was trendy.

Killing Floor is a straightforward co-op survival game that strips away pretense: you spawn, waves of increasingly nasty creatures attack, you shoot until they stop moving. Up to six players on maps like a blood-soaked warehouse or a grimy laboratories. The Specimen creatures are grotesque enough to stick with you, and the game nails the tension of a final-wave stand when ammo runs low and everyone's wounded. Fourteen years old now, it shows, animations are stiff, gunplay feels sluggish compared to modern shooters, and solo play is purely for practice. But the co-op loop still works because the difficulty curves properly, your loadout choices matter (pick a class, specialize in weapons), and there's real satisfaction in coordinating fire with a competent team. Free updates and Steam Workshop support kept it alive longer than expected. Not groundbreaking, but honest fun if you want mindless monster-slaughter without battle passes or live service nonsense.

GamerScout Verdict

For co-op hunters who value chemistry over polish, grab it cheap with friends and ignore the creaky engine.

Every store in this table quotes us in euros, so the EUR figure is the price the seller actually set, not our arithmetic — which is why EUR is also the currency we rank in. We only list an offer here when the store gives us its price in euros, so nothing in this table is a number we invented.

Pick USD, PLN, GBP, CAD or AUD in the header and we convert from EUR at the European Central Bank reference rate — converted amounts are prefixed with ~. Your bank or the store may apply a different rate at checkout. We never hide offers based on where you are: everyone sees this whole table.

We may earn a commission when you buy games through links on this page — at no extra cost to you. It never affects our rankings or verdicts.
