The new official L4D DLC is being released next Tuesday, Sept. 29. It's free for the PC, and a small price (around $5) for console users.
The new campaign picks up directly after the (successful) completion of the No Mercy campaign and takes you to the beginning of the Death Toll campaign. The helicopter (spoiler) that rescues you from the hospital rooftop crashes, leaving you at the mercy of the zombies again.
I'm thinking it's a shorter campaign then the other four, because Valve says, "...the average time to complete a versus match on Crash Course is around 30 minutes."
