Left 4 Dead

Left 4 Dead is a co-op action horror game set just after a zombie apocalypse. Up to four players guide survivors through infected territory, fighting zombie hordes and mutant monsters as they try to escape a devastated Ground Zero.

Campaigns

The survival co-op mode spans four “movies,” each made up of five large maps. You lead survivors across the rooftops of an abandoned metropolis, through rural ghost towns and into pitch-black forests, completing objectives and working together to make your escape. The 20 maps can be played by one to four human players.

An AI Director adjusts the frequency and intensity of zombie attacks to your performance, creating a different experience each time. Its attacks are designed to keep the action fast-paced without becoming overwhelming.

Game modes

Alongside single-player and co-op, Versus Mode pits two teams of four against each other. One team plays humans trying to get rescued; the other takes the roles of zombie boss monsters seeking to stop them. Survival Mode challenges you and your friends to hold out against the infected for as long as possible.

The Sacrifice

The Sacrifice is a campaign told from the L4D Survivors’ perspective as they travel south. It is a prequel to The Passing and advances the story with a finale built around “Sacrificial Gameplay,” in which players decide who will give their life so the others can live. The campaign is playable in Campaign, Versus and Survival modes.

Weapons and play

The game includes 10 weapons, along with matchmaking, stats, rankings and an awards system that support collaborative play. Designer’s Commentary provides a behind-the-scenes look at the game.
