New Vegas

New Vegas is the post-War version of what used to be Las Vegas, Nevada, deep in the Mojave Desert. Tycho was told about it by his father, who was also a Desert Ranger in Nevada. According to his memory, a fat mobster, similar to Gizmo from Junktown, used to live in Vegas. It appears to have either survived the Great War or was rebuilt after it. Judging by leaked information and the teaser trailer, Vegas avoided most of the nuclear bombs.

Appearances
New Vegas is mentioned by Tycho in Fallout. Vegas will appear in Fallout: New Vegas, an upcoming game by Obsidian Entertainment.

Behind the scenes
Las Vegas was one of the main and most central cities in Wasteland, the predecessor to the Fallout series. The fat mobster mentioned by Tycho is a reference to Fat Freddy, a character from Wasteland.
