New Left 4 Dead DLC announced

Crash Course Campaign Due in September

Valve Software has announced the next major downloadable content (DLC) update for its co-operative zombie thriller, Left 4 Dead (L4D).

Entitled "Crash Course," the latest DLC delivers new single-player, multiplayer and co-operative gameplay to both platforms. Targeted for release in September, "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

While containing both Survival maps and a Co-operative Campaign, the primary goal of "Crash" is to deliver a complete Versus mode experience in just 30 minutes, resulting in a streamlined version of the game's existing Versus campaigns. A recharge timer for infected teammates has also been added, and item spawn behavior has changed for more balanced gameplay.

Left 4 Dead: Crash Course is targeted for release in September and will be available free of charge on the PC and for 560 Gamer points on Xbox Live.
