Dead Money

 is the first add-on for Fallout: New Vegas, developed by Obsidian Entertainment and published by Bethesda Softworks, released on December 21, 2010 for the Xbox 360 platform.

As with Fallout 3 add-ons, it is likely to be a timed exclusive, but no information about future availability on the other platforms has been announced so far.

Changes introduced in the add-on include the level cap being raised to 35, new perks to match the higher levels, and new achievements.

Story
Dead Money is set in the Sierra Madre, an opulent and extravagant resort that was supposed to be the greatest casino in the west – except that it never opened. Bombs fell before the gala opening, and the Sierra Madre froze in time, its state of the art security system locking the place up tight. Nothing could get in, and none of the guests could escape. Years passed. The climate control and air conditioning system within the facility began to spit toxins into the surrounding city, causing a slow cloud and haze to form over the area - which proved lethal to anyone who tried to explore the city. Only a mysterious group called the Ghost People survived to call the city home, trapped inside what appeared to be hazmat suits and never speaking to their victims... only capturing them alive and dragging them away to the depths of the city deep within.

And so the Sierra Madre faded from the history books, only occasionally being seen in posters across the wastes, until it took on mythic ghost story status... a supposed "City of Gold" in the Mojave Wasteland where all the treasures of the Old World were rumored to be held. It was kept alive as a late-night saloon story by prospectors who'd claimed to have found maps leading there... and were willing to part with the "map" for a few caps. Or a drink. Or a warm place to sleep.

The Sierra Madre is a mythical place in the wastes, with travelers all risking their lives to find it. Only one man truly "found" it - and lived. After the fall of HELIOS One, Father Elijah of the Brotherhood of Steel set out to find new weapons to eradicate NCR. And in the process he found the Sierra Madre. The Courier is forced to go to the Sierra Madre and with a slave collar around his neck is forced to locate the treasure with 3 other people who have been captured.
