Vault 12

A Vault-Tec nuclear shelter, Vault 12 was located under the town of Bakersfield, California, and designed to house a thousand people. As intended by Vault-Tec, the blast doors did not close entirely after the bombs fell, resulting in the ghoul town of Necropolis.

Sections
Vault 12 is essentially identical in layout to the other Vaults encountered by the player. The first level contains the Medical Lab and entrance, the second is entirely living quarters, and the third houses the recreation area, armory, and command center. The command center notably lacks the space for an Overseer as seen in other Vaults - this is potentially because the Vault was not intended to be inhabited for a long period. Indeed, as the Vault has never entirely sealed, it is very dirty and weathered through 85 years of exposure and lack of maintenance. Only a handful of doors, computers and the elevators remain operable.

A number of Glowing Ones still inhabit the Vault. They can be evaded fairly easily by sneaking past, though they will attack the player if the water chip is removed but the water pump has not been repaired. This is one of the few occasions when Glowing Ones demonstrate they retain their full mental faculties to the player.

The Water Chip is located in the Command Center. It is easily spotted as it is attached to the only operational computer.

Appearances
Vault 12 appears in Fallout.

A unnamed Ghoul, wearing pieces of a Vault Suit, can be seen talking to the Puppet Man in the Fallout 3 comic, "One Man, and Crate of Puppets". It is most likely, that the Ghoul came from Vault 12, and migrated near Vault 77.

The fate of Vault 12 is detailed in a graphic novel available on the No Mutants Allowed website
