In Bethesda's latest newsletter, a designer on Fallout: New Vegas spills details on the upcoming "Dead Money," the Xbox 360-exclusive DLC extension to Fallout: New Vegas due on Dec. 21.
It's essentially a treasure hunt for a mysterious city, in this case the Sierra Madre, "an opulent and extravagant resort that was supposed to be the greatest casino in the west," but whose opening date, sadly, came after the bombs started falling. Its surrounding city, out in the Mojave Wasteland, is inhabited by the Ghost People, a people who are trapped inside hazmat suits thanks to pollution in the area.
You'll be spotting it the usual way - faint radio broadcast, in this case advertising the grand opening of the casino that never came. New foes and NPCs may be expected, including the Ghost People and the casino's "substantial defense systems."
Dead Money gets here on Dec. 21 and will cost 800 Microsoft Points.
