True to their word, Valve continue to add content for Left 4 Dead by adding a new campaign titled "Crash Course". This campaign 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.

The new campaign will be available in September. Changes for versus mode are coming too:

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.

This DLC will be available for free to PC, but will be 560 Gamer points ($7) on Xbox Live.

Destructoid has had the first play through, read about Crash Course here (spoilers!).
