New Vegas

New Vegas is built on the remains of pre-War Las Vegas in the Mojave. The New Vegas Strip is managed by Robert House, who utilizes his army of Securitron robots to maintain order in the post-War city.

Background
The oldest building in New Vegas is the Old Mormon Fort. Several roadways from before the war are still utilized, including Las Vegas Boulevard, Fremont Street, and the New Vegas Strip. The Fabulous New Vegas Sign has been refitted to read "New Vegas."

In 2065, Robert House deemed it "a mathematical certainty" that war would take place within the next 15 years, and he began preparations to protect Las Vegas. When the Great War occurred, lacking the upgrade data stored on the Platinum Chip, House's systems operated less optimally than planned.

The networked mainframes were still able to predict and force-transmit disarm code subsets to 59 warheads, neutralizing them before impact. Laser cannons mounted on the roof of the Lucky 38 destroyed another nine warheads, and of those that did break through the defenses, none impacted the main city and surrounding area. The effort to save Vegas was successful, but resulted in software glitches and system crashes, leading to Mr. House falling into a coma for a few decades. When Mr. House woke, he set out to hire salvage teams to find the chip in order to upgrade his systems.

NCR arrival
When NCR scouts were detected in the Mojave, House knew a force would be interested in controlling the dam and he began the effort to rebuild the Strip. The reconstruction effort began, undertaken with the assistance of Securitrons and recruited tribals thereafter known as the Three Families. House describes the Strip as "just a fraction of its former glory" after reconstructing the buildings to mirror their pre-War appearance.

The Strip's renovation was complete before the NCR forces entered the region, resulting in the signing of the Treaty of New Vegas, granting House sovereignty over the Strip. Provisions dictate that the NCR cannot prevent its soldiers and civilians from visiting the establishments, and House describes the NCR occupation as "the engine of my growing economy." The NCR does not attempt to annex New Vegas by force due to the Legion presence and was willing to compromise in order to maintain this balance of power.

Layout
New Vegas is situated in the Mojave Desert, surrounded by several mountain ranges. A network of sewers, some of which are inhabited by humans and other creatures, exist underneath the city. The areas outside of the Strip and Freeside are collectively referred to as "Outer Vegas." Radio New Vegas can be heard here and throughout the region.

The Strip
Several pre-War establishments have since reopened, powered by electricity from the Hoover Dam. He states that NCR citizens are "desperate to experience comfort, ease, luxury," and refers to them as a "society of customers."

The Securitrons on the Strip are not allowed to take action against the NCR troopers, the troopers are forbidden from carrying firearms, and the NCR was granted space on the Strip for an embassy. Street vendor are allowed to work on the Strip selling non-alcoholic drinks and snack foods, signing a franchise agreement to forfeit 50% of their profits to Mr. House at the end of each working day. The location serves as a major draw for tourism in the form of casinos, restaurants, and entertainment.

Freeside
Freeside is the main slum of New Vegas. Controlled by the Kings and the Van Graffs, the streets are dangerous and lack the luster of the New Vegas Strip. Many gamblers and tourists find themselves under attack by thugs looking for a quick source of caps. Recent tensions between the NCR and the Kings have worsened the situation. Similar to the rest of outer Vegas, Freeside shows resentment towards the NCR, who are seen as unwelcome oppressors.

Westside
The settlement supports its own militia and has become self-reliant, growing its own food and maintaining its own water supply.

North Vegas
The residents have problems with the Fiends and a smaller gang, the Scorpions, who remain a threat.

East Vegas
East Vegas is home to several businesses, including the Crimson Caravan New Vegas branch, a Gun Runners factory, and a clinic run by the Followers of the Apocalypse. Aside from businesses, the area is also home to sharecropper farms settled by NCR citizens encouraged to move west by the Thaler Act, and a refugee camp run by the NCR Army in Aerotech Office Park.

South Vegas
The southwestern region around Vegas belongs to the Fiends, who rule from the fortified ruins around Vault 3. Several of their raider compounds can be found outside of their main territory.

Appearances
New Vegas appears in Fallout: New Vegas, and is mentioned in its add-ons Dead Money and Honest Hearts, Old World Blues, and Lonesome Road, Fallout 4, and Fallout 76.

Behind the scenes
New Vegas is based on the real world location of Las Vegas, located in Clark County, Nevada. Many locations in the game have real world equivalents in and around the city, such as the casinos, neighborhoods, landmarks, and businesses.
