Vault 101

Vault 101 is a Vault-Tec Vault located north-west of Washington, D.C. in the Capital Wasteland. This vault is located in the hills west of the ruins of Springvale. The closest settlement is Megaton to the south-east. This Vault is located near the Potomac in northern Virginia.

Vault Experiment
The purpose of Vault 101 in the Vault Experiment was to test the role of the Overseer. The second Overseer decided to let a select few of the adults in on the secret to help keep it from the children, and over the years each subsequent generation had more and more residents who knew the truth about the Vault. In addition, the Overseer was able to communicate with, and even visit, the outside world by using the secret tunnel in the Overseer's office. However, for all other intents and purposes, the Vault's residents were sealed in: "We are born in the Vault, we live in the Vault and we die in the Vault." With the escape of the Lone Wanderer, the experiment enters a new phase.

History
Due to the degraded state of the file for this Vault in the Citadel terminal, the early history of this Vault is not well recorded. An analysis of the other Vault files suggests that Vault 101 was constructed in the 2060s.

For the history of this Vault between 2077 and 2241, see above.

In the mid-23rd century, a new Overseer assumed the leadership of the Vault. He was a proponent of contact with the outside world. In 2241, this Overseer sent a scouting party under the leadership of Anne Palmer into the Capital Wasteland. This expedition revealed the true nature of the aftermath in the Wasteland and contacted the citizens of the settlement Megaton. Sometime before the arrival of the Lone Wanderer's father in 2258, this Overseer disappeared on an expedition to the Wasteland. His successor, Alphonse Almodovar, ascended to leadership of the Vault. Under his rule, the Vault changed into a police state with a strict policy of isolationism.

Early in Alphonse's tenure as Overseer, James and his infant entered into Vault society. James, in his agreement with the Overseer, kept his child ignorant of their origins, convinced of their origins in the Vault. James was hired as the new Vault Physician. Nineteen years later, after James suddenly disappeared from the Vault, the Lone Wanderer was forced to flee and seek his/her father in the outside world for answers after fleeing a murderous Vault Security.

Upon meeting with Colin Moriarty in Megaton, the Lone Wanderer learned of his/her origins. He/she had been born outside of the Vault and was brought to Vault 101 by James after his wife died in childbirth. Though a few knew the truth, like Old Lady Palmer, they never divulged this to the Lone Wanderer.

Speaking with other residents of Megaton, the Lone Wanderer discovers that others have left the Vault over the past two decades. Moira Brown, the proprietor of Craterside Supply, recalls a girl who escaped "10 or 12 years ago", while the saloon owner Colin Moriarty recalls someone escaping 5 years ago. The man convinced Colin that residents of the Vault were brainwashed into believing lies.

The town of Megaton was founded by people who were trying to get into this Vault, and some of the skeletons of the people who tried to get in, as well as their banners demanding entry into the Vault (with strong languages), are still outside of the Vault door.

It should be noted that in the quest Trouble on the Homefront, it is hinted that most, if not all adult residents in Vault 101 were in on the experiment. Therefore James's sudden arrival in the Vault with the infant Lone Wanderer would not have caused too much concern among the residents, beyond the natural question of why the Overseer would allow the two newcomers into the vault when no outsiders were previously allowed.

Inhabitants
Vault 101 is populated by humans. These humans are descended from the original settlers. Occasionally, this facility is invaded by Radroaches. Vault Security is tasked with containing and killing these insects.

Layout
Vault 101 is divided into four sections by the game. These sections are Vault 101 Main Entrance, Vault 101 Overseer's Tunnel, Vault 101 Atrium/Upper Level, and Vault 101 Lower Level. The sections are separated by doors, and stairways connect floors and levels within two of the sections. Levels and rooms are identified by signs. There are two paths to the Capital Wasteland: a direct path from the Atrium and a hidden tunnel named the Overseer's Tunnel. The Vault faces east.

It is important to note that the sections are not directly stacked upon each other. They are staggered with each section moving progressively more westward as the Vault burrows deeper into the earth.

Notable loot
''Note: Almost all of these items are available either in "Escape!" or in "Trouble on the Homefront".''

Bobblehead
The Bobblehead - Medicine is on a desk in James' Office. You only have three chances to obtain this bobblehead. When you're about to take the G.O.A.T, when you escape the vault you'll come through his office, or when you return in the "Trouble on the Homefront" quest.

Custom Weapon Schematic
On a wall of the Physician's Office, a framed Quote of Revelation 21:6 can be found. When activated, the player will need to pick the 'average' lock. Inside can be found Rock-It Launcher schematics, 300 caps and a Holodisk called 'Home Sweet Home'. When accessed in Notes, 'Home Sweet Home' depicts James' voice lamenting over the death of his wife Catherine, discussing his new responsibilities as a father and the Overseer, whom he describes as an 'overbearing bully'. You need to pick the lock, which requires lockpick skill of 50 or greater.

Skill Book

 * Grognak the Barbarian - This book is a gift from Amata in "Growing Up Fast". This book reappears in "Escape!", in the Lone Wanderer's dresser, if the player hadn't read the book in the earlier quest.

Appearances
Vault 101 only appears in Fallout 3.

Related quests

 * Baby Steps
 * Growing Up Fast
 * Future Imperfect
 * Escape!
 * Trouble on the Homefront

Random Encounters
At higher levels, four or five Deathclaws will sometimes spawn down the hill from Vault 101.

Bugs

 * Fast-traveling or approaching the Vault entrance will in some cases result in a massive frame-rate drop.
 * Closing the Vault door manually using the outer console will work normally during Escape. However, approaching the tunnel exit will result in the Vault door reopening behind you exactly when it is supposed to close if you don't tamper with the console.
 * After completing "Trouble on the Homefront", Amata and Mr. Brotch may be standing in the medical room talking. Amata will simply tell you that you have to go, and Brotch will just say goodbye, but if you listen to their conversation they will sometimes discuss Amata's father and how to keep him in line - even if he's been dead because you killed him before leaving the vault at the beginning of the game.
