We all know the Midnight Riders, the southern-metal band in Left 4 Dead 2, right? We've killed zombies at one of their concerts at a pavilion, we listened to their new music on jukeboxes, but we never found their corpses, dead or zombified. But how's this for badass: their tour bus. Oh, and it's moving.
Rooster Teeth's Achievement Hunter guys (read: Geoff) found this, and it doesn't appear 100% of the time, but it's awesome nonetheless. Head past the break to view it (it automatically plays, and hearing that damned T-Mobile commercial over and over is annoying the piss out of me):
Guess they did make it out alive.
