Left 4 Dead is now coming out on November 20, Gabe Newell told Gamekings.tv in an interview. The zombie first-person shooter was originally set for November 4 date to go along with the "4" thematic. But its new release date will now coincide with the 10th anniversary release of Half-Life, Valve's first game.
While Valve has made team-based shooters before in its Team Fortress games, Left 4 Dead will pit four human players against a horde of ravenous zombies as they try to make their way to the end of each level.
