Bethesda announced today that that first piece of downloadable content for Fallout: New Vegas, entitled Dead Money, will hit Xbox Live Marketplace exclusively on December 21.

Priced at 800 MS Points, the pack thrusts players back into the barren wasteland, this time alongside a band of three captured wastelanders, to recover an artifact from the Sierra Madre Casino. Promised is “new terrain, foes, and choices.”

“We’re pleased to give fans a chance to expand their experience in Fallout: New Vegas this December with Dead Money,” said Bethesda VP Pete Hines. “The release of Dead Money illustrates our commitment to creating entertaining add-on content for players to enjoy in already massive games like Fallout: New Vegas.”

Although the exclusivity period is likely timed, there’s no indication as to when it might hit other platforms. Just don’t expect anything till next year, PS3 and PC folks.
