Left 4 Dead 2 and it looks like the Survivors will have a leg up on the undead hordes. It's good to know that even in the apocalypse, humans can sometimes catch a break.
In the PC version, players can check out Gib Fest, where all survivors are packing M60s with unlimited ammunition. Xbox 360 players will have to get a bit more up-close-and-personal in Chainsaw Massacre -- all survivors will have access to nothing but Chainsaws. Who wants zombie kebab?
