Having already promised additional downloadable content for the original Left 4 Dead, developer Valve today announced that a new campaign entitled "Crash Course" will be released for the cooperative zombie shooter in September.
The downloadable add-on will be available to owners of the PC version at no cost, with Xbox 360 players needing to pony up 560 Microsoft Points ($7) for the experience.
"New locations, new dialogue from the original cast, and an explosive finale" were promised, with Valve noting that the download--meant to bridge the gap between the existing "No Mercy" and "Death Toll" campaigns--will also pack new Survival maps alongside the new the single and multiplayer 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," the company explained. "A recharge timer for infected teammates has also been added, and item spawn behavior has changed for more balanced gameplay."
