Left 4 Dead Crash Course DLC Release Date

The primary goal of Crash Course is to deliver a complete Versus mode experience in just 30 minutes
Valve has announced that the next major downloadable content (DLC) update for its co-operative zombie thriller Left 4 Dead (L4D) is scheduled to be available on September 29th, free of charge on the PC and for 560 Gamer points on Xbox Live. Entitled "Crash Course", this DLC delivers new single-player, multiplayer and co-operative gameplay to both platforms. Crash Course bridges the gap between the end of the "No Mercy" campaign and the beginning of "Death Toll" in the original game, expanding the game universe with new locations, new dialogue from the original cast, and an explosive finale.
