Valve has announced some new DLC for Left 4 Dead, which will hopefully relieve some of the anguish caused when Left 4 Dead 2 was announced. The new campaign is entitled Crash Course and will be released with single player, co-op, and versus modes. The name seems fitting as Valve is hoping to provide a versus mode experience lasting roughly 30 minutes, much less than the current situation. Crash Course takes place between the No Mercy and Death Toll campaigns, providing gamers with some information as to what happened between the two. PC gamers will get the DLC for free, while Xbox 360 owners will have to pay 560 Microsoft Points on Xbox Live.
