Eurogamer writes: "Is Killing Floor the Tesco Value baked beans release of Left 4 Dead? Well, it's cheaper, contains many of the same ingredients, and isn't as nice, so perhaps yes. At the same time though, it's a game with a different approach, a fine Unreal Tournament 2004 mod heritage, and some great ideas that may not provide the fine-tuned wonderfulness of L4D, but at least make me feel guilty about beating it with a stick and screaming 'You're not Valve! You're not Valve!' while openly weeping. As such we'll kill the comparisons for a while. Sure, both games have pallid fat men that spew on people, but it's a spew of a different consistency and intent."
