Vault 8

Vault 8 is located in the post-War settlement of Vault City.

Background
Vault 8 was one of the seventeen control vaults, opening two years after the war. With the help of their GECK, the inhabitants established a city outside of the vault. The city relies on a reactor that controls its ability to expand. Martin is located in the lower level, tasked with looking after the equipment in the command center.

Level One
Beyond the outer blast doors and a long steel corridor lies a Seal'N'Safe Model 343 vault door, together with an airlock and security door. Doctor Troy is located here and can treat crippled limbs and radiation poisoning. He is a key figure in two quests, delivering a sample of Jet to him and making an antidote for Jet. Should the Chosen One become a Captain of the Guard, Marcus can be treated by Doctor Troy and all the ammunition stuck in his body removed.

Assisting Doctor Troy is a nurse named Phyllis who can provide some insight into how Vault City functions. Those who possess the magic 8-ball can access the emergency medical dispenser in the hall, for a super stimpak and two regular stimpaks.

Level Two
Level two is currently used only as storage. The rooms are filled with crates and abandoned equipment, though most doors have stuck power couplings or are locked. Vault City stores its supply of uranium ore for their nuclear power plant, as well as any other goods they trade with the outside. Spare water chips, originally intended for Vault 13, are located here.

Level Three
This level is divided into two distinct halves by a red security door. There is a meeting room, library, and computer core. At an intersection lies a storeroom, where all the vault's basic supplies are kept in lockers.

The second part, the actual command center, is separated by a security door with a bright red light, beyond which lies the security station with the vault's armory. Just beyond is the main control room, where the central computer, the primary control stations for the water processing computer. Last is the overseer's chamber, where his hydraulic pedestal and control seat is located.
