“Fight together! Or die alone…”
An unknown virus is devastating humanity at an incredible rate. Those infected become extremely aggressive psychopaths who attack anyone still in their right mind. You are one of the “lucky” ones who have developed immunity to this horrific disease. Shoulder to shoulder with other survivors like you, you must escape a city teeming with thousands of crazed infected. Can you band together and make it out of this nightmare, or will you panic, succumb to the onslaught of the zombie horde, and die alone?
The game was created by the makers of Counter-Strike and is based on one of the latest versions of the legendary Source engine.

And a stroke of genius—the “AI Director,” which automatically tracks players’ behavior and skill levels—lets players enjoy playing through the game again and again, as events unfold differently every time.
