Vault 21

Vault 21 is a Vault-Tec vault that was once hidden under Las Vegas, Nevada. It has since been converted into a hotel/casino and acts as one of many sources of income for Mr. House and his young New Vegas empire.

Background
Located in downtown Las Vegas, Nevada, Vault 21 was a unique Vault Experiment: everyone in the vault was equal, it was created with a perfectly symmetrical layout, and all conflicts and problems were solved through gambling. Reliance on luck to solve problems created what might be considered the perfect realization of anarchy: a society in which everyone is equal and no one has an advantage over the others. Vault-Tec ensured that every person admitted to the vault when it first sealed was a compulsive gambler, and were unable to decline when Vault-Tec personnel running the vault informed them that this was how the vault was to be run. The original dwellers then passed on their lifestyle to their children and so on.

However, as with all utopias, the peace was not lasting. Sometime between 2271 and 2281, Robert House learned Vault 21's location. Resisting attempts to be assimilated into his empire, the inhabitants agreed on gambling to settle the issue. The game they played to settle the deal was blackjack and almost the entire vault was in attendance. In a risky bet, the supporters of House won against the opposition, and Vault 21 was stripped it of its bounty of useful electronics and equipment and partially filled in with concrete, forcing the dwellers to resettle in the wasteland and the Strip. At Sarah Weintraub's and Michael Angelo's (a.k.a. Sheldon Weintraub) insistence, he left the topmost level intact and allowed them to establish a hotel there, which became another source of income for his fledgling empire.

Vault 21 is one of the extremely rare experimental vaults which successfully protected its inhabitants while fulfilling the parameters of its experiment. The experiments in most other Vault-Tec vaults ended up killing or permanently altering their inhabitants. Although Vault 3 was a control vault, intended to recolonize the surface after an extended period of time, when its door was opened the Fiends slaughtered its residents and took over.

Layout
The vault's main cog door has been transformed into a sign advertising the vault/casino. "Vault 21" is emblazoned on it in neon lights. The vault entrance is an above ground building which contains the Vault 21 gift shop. The gift shop is run by one of the only two native residents to have remained, Sarah. Stairs lead from the gift shop down into the vault.

The vault has been converted into a casino and hotel. There is a central atrium with gambling tables, a hallway with living quarters, including Sarah's room and a guest room that the player can rent. Another door leads to the cafeteria/diner. The lower levels were filled with concrete by Mr. House and are inaccessible except for the maintenance level, which is accessible from the basement of The Tops, where the Chairmen appear to have tried to break in. This level consists of a long hallway with a few small rooms branching off of it. The elevator in Benny's suite leading to it is locked unless he is attacked in the Tops, and the tunnel ends in another locked door.
