Xbox 360 owners will enjoy the first Fallout: New Vegas DLC exclusively when it launches next month.
Dead Money will be released on 21st December exclusively on Xbox Live for 800 MS Points.
In Dead Money, you're the victim of a raw deal, and must work alongside three other captured wastelanders to recover the legendary treasure of the Sierra Madre Casino.
New terrain, foes and choices will greet the player.
"We're pleased to give fans a chance to expand their experience in Fallout: New Vegas this December with Dead Money," said Pete Hines, VP of PR and Marketing for Bethesda Softworks.
"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."
Obsidian's Fallout: New Vegas launched last month. Dan Whitehead awarded the post-apocalyptic openworld role-player a stonking 9/10.
