Zombie apocalypse is bad news for humans, but great news for gamers. That’s where it all starts in this horrific action-thriller from the minds behind Half-Life and Counter-Strike. Left 4 Dead thrusts you into an infection-ravaged world, where you’ll battle swarms of zombies and other indescribable mutants. The innovative story line has been hacked into four distinct “movies” designed for solo stardom or for up to four co-op players. Plus, each story unfolds across multiple maps. Keeping with the cinematic theme, the game features a revolutionary AI Director that serves up new monsters and scenarios each time you play. And there’s a designer’s commentary that sends you behind the scenes.
