Left 4 Dead 2

Left 4 Dead is a co-operative multiplayer survival horror that pits four playable or AI-controlled survivors against hordes of aggressive "infected" - the victims of an apocalyptic plague.

The Survivors' goal is to help each other make it through various scenarios to safety. The Infected are controlled by an AI director that dynamically balances difficulty and mood depending on the players' progress and situation. In an alternate game mode, human players can control up to four mutated Special Infected with special abilities and cooperate to stop the Survivor players.
