If you haven't gone through the entire campaign for Left 4 Dead 2 you might want to avoid reading the rest of this post . . . . ok, for the rest of you, you likely know that in the Dark Carnival campaign for Valve's just released zombie shooter sequel, there are mentions of the Midnight Riders, a fictional Southern rock band that was set to play at the amusement park at the center of the campaign before the infected apocalypse hit. Indeed the final campaign level has the four survivors facing off against the zombies on the Midnight Riders' stage.

The campaign level has posters for the group which showed a web page. Checking out the web page in the real world shows the image you see above. The big question: Is this just some viral fun from Valve or a hint that we could see a Left 4 Dead 2 DLC campaign featuring players controlling the rock group? Hey, there are four members there.
