Upcoming co-operative zombie apocalypse survival sim (new genre please?), Left 4 Dead will have gamers screaming in delight come November 4.

The shooter, which will ship for 360/PC, features four-player co-op and will finally allow players to control zombie hoards. L4D will also feature a robust AI – think a lot of algorithms and “sequencing,” stuff like that – that will ebb and flow with the action of the game.

Video of the game looks amazing so get ready for some zombie action that would make Romero smile (or sue).
