Nastier, stronger and faster can be said about the zombies looking to dismember you and your comrades in Valves latest gore-fest. The game Left 4 Dead 2 which just release November 17th alongside Assassins’s Creed 2 and God Of War: Collection has managed to infest over 2 million homes, very impressive indeed.

This games should probably be on top of every mature classified eligible Xbox 360 and PC users list as it packs a nasty punch. According to Valve, Left 4 Dead 2 sales to date have already doubled the sales of the original title.
