Vault 12

Vault 12 is a vault constructed by the Vault-Tec Corporation in Bakersfield, now the post-War ghoul settlement of Necropolis.

Background
Constructed under Bakersfield, Vault 12 was described as "built with every amenity in mind for the prospective Vault Dweller," and that it had "been fitted with the newest in Vault Water Purification Systems. Able to take even the waste located in the sewers of Bakersfield, this system is able to deliver over 15,000 gallons of pure, refreshing drinking water every day." The vault's true purpose was to study the effects of radiation on the residents by way of a non-functioning vault door. Those who sought shelter there were turned into ghouls, and subsequently founded the city of Necropolis.

The location is controlled by Set. He is disgusted by the peaceful ghouls that inhabit the area, but does not start conflict due to the balance of power.

Layout
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. Only a handful of doors, computers and elevators remain operable.

A number of glowing ones still inhabit the vault and will attack the Vault Dweller if the water chip is removed and the water pump has not been repaired. Additionally, if the water pump has been repaired, the glowing ones will not attack at all so long as the Vault Dweller does not attempt to loot.

The water chip is located in the command center. It is attached to the only operational computer. If the first glowing one that one would encounter is left alive, and the water chip taken without repairing the water pump, he will remain even after the other ghouls have died of dehydration, and comment on this fact.

Sewer entrance (Fallout)
This area can be accessed going down through a hole in the watershed sewers. Previously, a ladder had to be descended and was situated at the right of the ghoul prisoner cell. Two glowing ones are located here. At the end of the corridor on the left is an elevator.

Living quarters
The 2nd level. Six glowing ones are located here. Level 3 can be accessed using the elevator.

Command center
The final or 3rd level. Again, there are six glowing ones but also one dead body. A computer with red and blue lights is located in the eastern part, interacting with that computer will yield the water chip.
