This co-op action horror game for the PC and Xbox 360 casts players in an epic struggle for human survival against swarming zombie hordes and terrifying mutant monsters. Set in the immediate aftermath of the zombie apocalypse, L4D's survival co-op mode lets you blast a path through the infected in four unique campaigns. Each campaign, or "movie", is comprised of five large maps, and can be played by one to four human players, with an emphasis on team-based strategy and objectives. Making your way through an abandoned metropolis, rural ghost towns, and pitch-black forests, you and your friends join forces to escape a devastated Ground Zero crawling with infected enemies.

Innovative technology dubbed "the AI Director" is used to generate a unique gameplay experience every time you play. The Director tailors the frequency and ferocity of the zombie attacks to your performance, putting you in the middle of a fast-paced, but not overwhelming, Hollywood horror movie.

Versus Mode also lets you compete 4-on-4 with friends, playing either as a
human trying to get rescued, or as a zombie boss monster that will stop at nothing to destroy them.
