Never been on the Indiana Jones ride at Disneyland, Temple of the Forbidden Eye? If you own Valve's Left 4 Dead 2 I've got good news for you - someone's just recreated it. You can either tour the ride normally... or go inside it and fight zombies. It's even got John Rhys-Davies in there.
Also from the same author is a recreation of the Pirates of the Caribbean ride. Both include accurate sound effects and are near-perfect recreations. Anyone want to kill some zombies tonight?
