Vault 3

Vault 3 is one of the Vault-Tec Vaults. The vault is completely intact by 2281, with only some raider graffiti, suggesting that it was only recently vacated, or that the Fiends are the Vault's original residents.

It is located under a building in the South Vegas Ruins and is the base of operations for a gang known as the Fiends. It's location can be gained from the colonel at Camp McCarran after volunteering to help with the gang problem.
