How has it taken this long for someone to finally send us a video of Left 4 Dead's survivors playing a surprisingly appropriate L7 cover in Rock Band 2? It makes no sense.

But this in-Rock Band representation of the survivors of the zombie apocalypse deserves kudos for mostly nailing the look and feel of the Left 4 Dead quartet—even if some of the moves that Rock Band Zoey does feel awkwardly sexualized. We think of her like a sister, so all that writhing is... creepy.

Clearly what we need now is a crowd editor. Something that lets us put giant, pus-filled sores and obscenely long tongues on Rock Band concert goers.

Thanks to Matt for the heads up!
