UPDATE: The campaign is actually titled “Dark Carnival” it seems. Left the rest of the post as is:
GameTrailers revealed some video about Left 4 Dead 2′s “Fairgrounds” campaign and the pending DLC for Left 4 Dead, Crash Course. In Left 4 Dead 2, there’s a cool amusement park scene, and an eerie carousel, but I’m hopeful for a working rollercoaster. 
Crash Course opens with a helicopter crash, as it bridges the gap between No Mercy and Death Toll, and yes, confirms there are only two maps. Boo hoo, but still fun!
