That's right. In a nigh-undisturbed, dusty GameSpot warehouse, diligent archivists have recently unearthed tantalizing clips of footage from a long thought-to-be-lost silent video game, Sam and Max: The Devil's Playhouse, Episode 2: The Tomb of Sammun-Mak! Makes that Metropolis restoration look like peanuts in comparison.
Well, go and check it out. It's only so often such a priceless piece of video game history is rediscovered.
(Actually, the trailer is hardly long-lost, but who cares? It makes a good news post, and admirably sets the mood for the game. Which looks awesomely old-timey, don't you know.)
