Valve has confirmed that Crash Course, the second slice of downloadable pie for Left 4 Dead, will be out for Xbox 360 and PC next Tuesday, September 29.
Speaking at EA's pre-TGS press conference (via Joystiq), Valve's Kim Swift also confirmed that a Left 4 Dead 2 demo will be released on October 27. Happy days.
The Crash Course Campaign bridges the gap between the end of No Mercy and the beginning of Death Toll in the original game, says Valve, adding 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, it says, resulting in a streamlined version of the game's existing Versus campaigns.
It'll be free on PC and 560 MS Points (£4.76) for Xbox 360 users.
