Valve have unveiled the first bit of video from the Fairgrounds campaign in Left 4 Dead 2.

GameTrailers TV talked to Gabe Newell and Chet Faliszek about the campaign.

"That's almost like our fantasy level, if you like," Faliszek said. "A merry-go-round starts up in the middle of a zombie apocalypse."

The footage features the Charger and Spitter strutting their undead stuff and also shows off the new incendiary ammo.

Left 4 Dead 2 will be coming to the PC and Xbox 360 on 17th November, keep coming back and we’ll keep you very informed.
