From Valve (the creators of Counter-Strike, Half-Life and more) comes Left 4 Dead, a new kind of action game for the PC and Xbox 360™ that features single player, co-op and multiplayer game modes.

Set in the immediate aftermath of the zombie apocalypse, L4D offers four expansive "movie campaigns" that challenge you and your fellow survivors to battle thousands of swarming zombies as you travel across the rooftops of an abandoned metropolis, through rural ghost towns and pitch-black forests. In addition to the movie campaigns, Left 4 Dead features a Versus mode that allows you to play as the Boss Zombies.

New technology dubbed "the AI Director" is used to generate a unique gameplay experience every time you play. The Director tailors the frequency and ferocity of the zombie attacks to your performance, adjusting pacing, special effects and audio on the fly.

Left 4 Dead is due for worldwide release on the PC and Xbox 360 on November 18 in the US, and Nov 21 around the globe. A playable demo will be available November 11 on both platforms the world over.
