Hardcore mode is an optional setting that attempts to make the game more realistic, with gameplay elements such as dehydration, and non-instantaneous healing. A cinematic teaser trailer and a gameplay trailer were then subsequently released. The first official information was released in the February 2010 issue of PC Gamer. The game was announced on April 20, 2009, at Bethesda's London showcase. Sawyer has stated he believes the game realized most of his development ideas during those 18 months.

The game spent a total of 18 months in development. The biggest technical issue that the team faced during development was working with the PS3's hardware as New Vegas is a very memory-intensive game, they had difficulty with the PS3's split memory pool. Project director Joshua Sawyer described the development process as having used 'sprint overtime,' though he does not consider it crunch time. This idea was abandoned due to issues with the engine, specifically with how the weapons and armor would work. The game was originally slated to have three playable races - human, ghoul, and super mutant. They used development tools for a few months before they were given the source code, which let them dive in to deeper development. The team initially did not have access to the source code until Bethesda cleared the security of it. Obsidian submitted a three-page pitch to Bethesda for the project, which they named ' Fallout: Sin City.' The game was later renamed to ' Fallout: New Vegas.' East Coast, Obsidian set the game in the American West.

It was specifically designed to be more of an expansion rather than a sequel Obsidian, however, saw the project as akin to the Grand Theft Auto titles Vice City and San Andreas - not numbered entries, but still full games in their own right. They knew the game would not be a direct, traditional sequel to Fallout 3, and it was referred to as ' Fallout 3.5' within Obsidian. Discussions for New Vegas began between Obsidian and Bethesda in 2008/09.
