Left 4 Dead fans are sure to have a busy fall. According to Shacknews, Valve Software has announced the date it plans to release the Crash Course add-on for the original game: September 29, or next Tuesday. Also, the company said it intends to release a demo of the sequel, Left 4 Dead 2, on October 27.
The Crash Course downloadable content will only work with the original title, and as we told you before, it will bring new locations, new dialog, and a "complete Versus mode experience in just 30 minutes," in Valve's words. The DLC will also bring a few tweaks to the experience, including an attack recharge timer for super-infected players in Versus mode.
Crash Course will be available free of charge for Windows users. Xbox 360 users will have to pay $7, however.
As for the Left 4 Dead 2 demo, Shacknews says Valve revealed little other than the October 27 release date. Still, the site points out that folks who pre-order L4D2 might get first dibs (or potentially exclusive access) to the demo. In any case, Valve will reward pre-orders with a special melee weapon—the baseball bat.
Update: Shacknews now reports that the demo will be exclusive to folks who pre-order Left 4 Dead 2 either on Steam or for the Xbox 360.
