A co-operative multiplayer action game from the makers of "Counter-Strike," Left 4 Dead is built atop the most advanced version of the Source Engine and introduces version 2 of Turtle Rock's artificial intelligence (A.I.) technology.

Together with a handful of fellow Survivors, you must fight your way to safety or die alone. One of the "lucky" few apparently immune to the sickness, you, unfortunately, are also trapped in a city crawling with thousands of the bloodthirsty Infacted. The pandemic's victims become grotesquely disfigured, wildly violent psychopaths, attacking the uninfected on sight. A new and highly virulent strain of the rabies virus emerges and spreads through the human population with frightening speed. One of the "lucky" Fight together.or die alone.
