Left 4 Dead is the new survival co-op action game from Valve that blends the social entertainment experience of multiplayer games such as Counter-Strike and Team Fortress with the dramatic, narrative experience made popular in single player action game classics such as the Half-Life series of games.

The PC version of the game will be playable by the press and public at a series of upcoming events including Leipzig Games Convention, (Germany), Festival du Jeu Video (France), and PC Gamer Showdown (UK). The worldwide debut of the Xbox 360 version will be at the upcoming Penny Arcade Expo (PAX) in Seattle, WA. Members of the development team will be on hand at each event to provide information and give away some Left 4 Dead memorabilia.
