Left 4 Dead is a survival action game from Valve that blends the social entertainment experience of multiplayer games such as Counter-Strike and Team Fortress with the dramatic, narrative experience made popular in single-player action game classics such as the Half-Life series of games. Set in the immediate aftermath of the long-awaited zombie apocalypse, L4D's single-player and co-op game modes are played out across four sprawling "Movies" set in a variety of urban and rural environments. Each "Movie" has an over-riding team objective, is comprised of five large maps, and may be played by 1 to 4 human players. New technology dubbed the "AI Director" is used to procedurally generate a different experience each time the game is played. Just as in Hollywood films, the Director calls for new monsters, sounds, and action as it tailors the gameplay experience based upon the team's performance.
