Vault 3

Vault 3 is one of the Vault-Tec Vaults. The vault is completely intact by 2281, occupied by the Fiends, who killed the vaults original occupants.

Location
It is located under a building in the South Vegas Ruins and is the base of operations for a gang known as the Fiends. Its location can be gained from the colonel at Camp McCarran after volunteering to help with the gang problem, from Elder Mcnamara of the Brotherhood of Steel during the quest Still in the Dark, from Diane during the quest Aba Daba Honeymoon, or from Private Ortega in the Barracks at NCR Sharecropper Farms.

Gaining Entrance
Use the Vault Door Control Pad to the left of the actual vault door to get inside. You can infiltrate the Vault by passing a speech check, by wearing a Great Khans outfit and telling them that you're shipping Chems, or by "simply" killing everyone.

Background
The original Vault 3 inhabitants opened the doors for the Fiends thinking they would be friendly. At this point the Fiends killed all the Vault dwellers inside and took over. It is not known if any of the original residents survived. the purpose of this vault was to stay shut and never open. It is suspected that the dwellers were having a breakdown with the floods like every other vault in the area (except vault 21.) The breakdown probably pushed them to open up their door in hopes of finding help. Unfortunately for them, they did not.

Layout

 * Vault 3 consists of 3 areas, Recreation Area, Living Quarters, and Maintenance Wing.
