GameSpot (26 мая 2009). — «Visually, Killing Floor compares poorly with contemporary shooters, thanks to its five-year-old engine(...)The sound effects are outstanding, especially for guns, and you can often use subtle sound clues to detect incoming enemies. Unfortunately, the voice acting and soundtrack don't achieve the same level of quality(...)Meanwhile, derivative, generic metal music does little to improve the tone(...)It's absurd and crass, and yet you can't help but enjoy it».
