Experience all the sights and sounds of fabulous New Vegas, brought to you by Vault-Tec, America's First Choice in Post Nuclear Simulation. Explore the treacherous wastes of the Great Southwest from the safety and comfort of your very own vault: Meet new people, confront terrifying creatures, and arm yourself with the latest high-tech weaponry as you make a name for yourself on a thrilling new journey across the Mojave wasteland. A word of warning, however - while Vault-Tec engineers have prepared for every contingency (should not be construed as a legally-binding claim), in Vegas, fortunes can change in an instant. Enjoy your stay.

The Mojave Wasteland is a dangerous and desolate place… so you feel the need for some companionship during your adventure. Like Fallout 3, New Vegas allows you to have one humanoid and one non-humanoid companion at any time.

“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.”

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.

Dead Money will be available exclusively on Xbox Live beginning December 21, 2010.

Key Features :

• Feel the Heat in New Vegas! Not even nuclear fallout could slow the hustle of Sin City. Explore the vast expanses of the desert wastelands - from the small towns dotting the Mojave Wasteland to the bright lights of the New Vegas strip. See the Great Southwest as could only be imagined in Fallout.
• Feuding Factions, Colorful Characters and a Host of Hostiles! A war is brewing between rival factions with consequences that will change the lives of all the inhabitants of New Vegas. The choices you make will bring you into contact with countless characters, creatures, allies and foes, and determine the final explosive outcome of this epic power struggle.
• New Systems! Enjoy new additions to Fallout: New Vegas such as a Companion Wheel that streamlines directing your companions, a Reputation System that tracks the consequences of your actions, and the aptly titled Hardcore Mode to separate the meek from the mighty. Special melee combat moves have been added to bring new meaning to the phrase "up close and personal." Use V.A.T.S. to pause time in combat, target specific enemy body parts and queue up attacks, or get right to the action using the finely-tuned real-time combat mechanics.
• An Arsenal of Shiny New Guns! With double the amount of weapons found in Fallout 3, you'll have more than enough new and exciting ways to deal with the threats of the wasteland and the locals. In addition, Vault-Tec engineers have devised a new weapons configuration system that lets you tinker with your toys and see the modifications you make in real time.
• Let it Ride! In a huge, open world with unlimited options, you can see the sights, choose sides, or go it alone. Peacemaker or Hard Case, House Rules, or the Wild Card - it's all in how you play the game
