Bethesda and Obsidian have released the first trailer for Dead Money, their first DLC episode for Fallout: New Vegas, due to hit the Xbox 360 exclusively from December 21.

As the victim of a raw deal you must work alongside three other captured wastelanders to recover the legendary treasure of the Sierra Madre Casino. In Dead Money, your life hangs in the balance as you face new terrain, foes, and choices. It is up to you how you play your cards in the quest to survive.

While many a Fallout: New Vegas non-Xbox 360 player is likely to be up in arms over the content's exclusivity, 360 players will get an action-packed, all-new narrative adventure with new characters, weapons, enemies and Achievements.
