Eurogamer writes: "My favourite moment in Left 4 Dead? I'm playing Versus mode, and we've reached the apex of the Blood Harvest campaign in a desperate farmhouse siege against overwhelming odds. I'm part of the overwhelming odds, playing the corpulent blob that is the Boomer. I wobble up to a window and look inside, to see Louis firing away desperately at the horde around him. I just watch, smiling, waiting for him to turn in my direction. Only when he does, when he realises that I'm standing there, do I spray him with my zombie-attracting vomit, prompting another wave of infected to crowd in and hammer him to death."
