Vault 11 has been abandoned for decades, though few people know the story of its terrible past.Fallout: New Vegas loading screen

Vault 11 is one of the Vault-Tec vaults, located in the Mojave Wasteland. It is west of Boulder City and south west of the 188 trading post.


Vault 11 was probably constructed along with the other Vault-Tec vaults in the mid 2060s to the early 2070s. As with the majority of other vaults, Vault 11 was a social experiment. In this experiment, the inhabitants of Vault 11 were told that they must sacrifice one of their fellow vault dwellers each year, and that, should they refuse, all the dwellers will be killed. In actuality, if the residents refused, an "Automated solution response" was supposed to be played. The message stated that by choosing not to select one of their own as a sacrifice, the dwellers are "a shining example to humanity" and that no one will be killed. They are also informed that the vault door is then unlocked so they can come and go as they please but are urged to consult with their Overseer before they do so. However, by the time Vault 11 inhabitants refused to continue sacrificing their residents, only five survivors remained.

'Elections' and the Overseer's roleEdit

Evidence gathered from computer terminals throughout the vault attests that the vault residents were required to select an annual sacrifice from among their members. Therefore, at the end of the Overseer's term of office, the Overseer was required to enter a chamber below the Overseer's Office to be executed by the vault's computers. The computer did not require that the sacrifice should be the Overseer, but if a sacrifice was not selected, the computer controlling the vault would kill them all. Of the original residents, only the Overseer had entered the vault knowing about the yearly sacrifice. The residents of the vault, in their shock and anger at discovering this after having already been sealed inside the vault, selected the original Overseer (whom they viewed as having betrayed them) as the first sacrifice. This decision would marry the positions of Overseer and Sacrifice until the end.

In this vault, several voting blocs emerged to exercise power and influence over other vault residents. Prior to the final election, Roy Gottlieb, leader of the most powerful of the voting blocs, the Justice Bloc, confronted Katherine Stone. He threatened that if she did not perform sexual favours for the members of their bloc, they would nominate her husband, Nathan Stone, for Overseer (it is hinted that he may have made enemies of the Justice Bloc because of an unusual winning streak during the poker games he attended). Katherine, fearing for her husband, complied. Much to the shock of the Stone family, the Justice Bloc nominated Nathan for Overseer regardless. Because candidates were typically people who had outraged the community, they were usually nominated by several blocs; in Nathan's case, his nomination was backed only by the Justice Bloc.

Fearing for the fate of her husband, Nathan Stone, Katherine decided that she had to save him using the only method she felt left available to her: she began to stalk and kill the members of the Justice Bloc, which held a very narrow majority. Upon her capture, she confessed to her crimes immediately, explaining not only her plan but also her reasoning: as a murderer, she was sure the voters would elect her in her husband's stead, because it was a choice "they could live with."

Katherine Stone's first act as Overseer, "Overseer Order 745," dissolved the election process and decreed that the position of Overseer would be chosen using the vault's computer systems and a random number generator. The Justice Bloc, aghast that they were going to lose the ability to control vault life by means of election threats, not only feared that one of their own members would be selected, but also worried that the damage to the vault's social structure would be so severe that they would have permanently lost power by the time one of their own members was elected and could reverse the Order. They decided to stage an armed coup to force Katherine to reverse Overseer Order 745. The fighting that ensued killed nearly all of the remaining vault dwellers population, and in the end only five people survived.

The Final SacrificeEdit

The first audio log discovered by the player as they enter the vault records the fate of the final survivors. In an act of suicide they defied the vault computer and refused to send any more sacrifices, only to discover that their defiance was exactly what the vault computer wanted. They were given the freedom to leave the vault and congratulated for their selflessness.

After learning the awful truth about the vault experiment, the five survivors discussed committing suicide to punish themselves for the events that happened in the vault, and to prevent the outside world from learning about their shameful behaviour. However, they were not unanimous in their decision. In the audio log, there is an argument among the five of them: a man referred to as "Voice 1" tries to convince the other four (three males and a female) to leave the Vault. Voices 2 (female), 3 (referred to as Harry), 4 and 5 want to commit suicide after finding out about the vault's experiment, while "Voice 1" is having second thoughts and tries to convince them to leave the vault and spread the word about what happened there. At the end of the audio log, four gunshots are heard, followed by a sigh from Voice 1 and the sound of someone dropping a gun. Four bodies are found in the entrance of the vault.


Entrance levelEdit

In 2281 the reactor and the water purification system of Vault 11 has been damaged by age and the destruction from a civil war among the dwellers. Radioactivity, and especially radioactive water, are some of the hazards of the vault. It is therefore advisable to pack some RadAway and Rad-X when journeying to Vault 11. Since portions of the vault are under water, you may want to head over to Nellis Air Force Base and acquire the rebreather (from the quest, Volare!) that allows you to breathe under water before entering this vault, although there are also air pockets in the flooded areas. Other than the radiation on the lower levels, the only enemies you will encounter inside the vault are giant mantises, giant rats and two bark scorpions just inside the entrance from the Mojave Wasteland.

Prior to entering the vault, there is a hollowed out rock on the right as you approach the outer door. The entry tunnel is filled mostly with mantises of various sizes and a few bark scorpions, and the open vault door leads to a larger entry room than vaults on the East Coast. Four skeletons lie on the floor here. A working terminal near the door allows the Courier to access an audio log with some information about the fate of the vault. The next room has exits to the clinic straight ahead. On the left is a dead-end hallway with a classroom and a cigar lounge. On the right a hallway with bathrooms and another clinic entrance has stairs on either end.

The stairs nearest the entrance hall lead to a floor containing a lab, and more stairs down. The stairs on the opposite end lead to a floor containing a computer room. One of the computers is booby-trapped, and will explode if you try to access it.

The entire vault has been plastered with propaganda for an election for a new Overseer, but each candidate is expressing outrage at having been nominated and trying to point out not only their innocence but why the other candidates deserve to be Overseer for their sins. Deeper in the vault, sandbag barricades, multiple traps, and several skeletons indicate that there had been prolonged fighting at some point.

Living quartersEdit

Stairs lead down to a large common room with exits leading to the male and female dorms and another exit labeled "Admin." This leads to the security office, and to the levels containing the Overseer's office and the utility room. The dorms are a long series of interconnected rooms, and the only place where Vault 11 jumpsuits can be found. Another audio log can be found on a locked terminal, with the password in a footlocker a few feet away.

There is a copy of Pugilism Illustrated in the female dorm, second door on the right, under the overturned dresser right as you walk in. A small cache of flamer fuel and 5.56 rounds is concealed under and behind a large immovable mop bucket in the male dorms.

Through the door marked "Admin," down the stairs and to the left is a locked door (Lockpick skill of 75), which can also be unlocked by the adjacent terminal (Science skill of 75) leading to a storage room with an assortment of ammunition, including a mini nuke. The security office contains a terminal with Katherine Stone's deposition, and more ammunition. At the opposite end of the hall are several flights of stairs leading down to the lower levels.

Lower levelEdit

The Overseer's office is past a hallway on the right. Enter the Overseer's office cautiously as there is a rigged shotgun at the entrance. This has a locked terminal (password required) and some random loot scattered around the room. Past the Overseer’s office the passage to the atrium is blocked. The hallway before the office leads to the utility room and another blocked passage to the atrium.

For the quest Still in the Dark for the Brotherhood of Steel, enter the door marked utility on the same level as the Overseer's office, go down a flight of stairs, then proceed down the hall to a submerged flight of stairs. Swim down to the door at the bottom. The differential pressure controller is in this room in a locker on the right side of the room.

To access the atrium, the Courier must go down through the flooded, radioactive engineering level via the utility room. The totally flooded lower reactor level is the only way to proceed without 50 Lockpick to open a door above the flooded level. There is only one air pocket in this area, so one must be careful about getting out of the flooded area alive. It is recommended to open one or two doors then backtrack to the air pocket, and with the way clear you can proceed to the next set of stairs and forward (the rebreather from Volare! is also useful here).

The atrium can now be accessed, and the Vault 11 overseer's terminal password can be learned from the terminal on the upper balcony or a holotape, Prepared speech of Gus Olson, ombudsman, for the annual overseer election, on the podium below. This level also features the vault cafeteria, which has a large supply of food and a first aid box. Be careful when entering the cafeteria as there are lethal explosive traps in the doorway. In the back of the cafeteria you will find a kitchen in which there is a gas leak and an explosive trap that is triggered upon entering, which will cause a chain reaction.

Sacrificial ChamberEdit

Accessing the Overseer's terminal with the aforementioned password can open the chamber under the desk. This opens into a long tunnel. At this point a pre-programmed voice speaks as the Courier approaches a door illuminated by a bright light. At the end of the tunnel is a room with a single chair in the center, along with a projector. The voice instructs you to sit in the chair to start the presentation, if you do not comply in a timely manner the voice will start to say "you have no choice but to sit in the chair." The exit door locks as soon as the presentation starts. Pleasant scenes are shown while a voice reassures the sacrifice that they lived a good life and their next one will be better yet. At the conclusion of the presentation, wall panels on both sides of the room slide back, and four robots and eight turrets will simultaneously attack the player. If you remain in the chair till the end of the film you will more than likely be killed as the robots and turrets open fire immediately. Once the automatons are dealt with, the player can then access a small room with the vault mainframe computer inside. This computer unlocks the door and reveals the true purpose of the vault: the idea was to see how long it would take for the population to refuse further sacrifices, essentially a test of self-preservation versus morality.

"Happy Trails" slidesEdit

The Happy Trails slide show is a presentation created by Vault-Tec Industries specifically for use in Vault 11 and its experiment. The slide show would play when a chosen sacrifice would enter the sacrificial chamber and sit down in the chair in the middle of the room. The purpose of the slide show was meant to bring the sacrifice to false sense calm and acceptance before their violent death.

Behind the scenesEdit

  • Vault 11 was designed by Eric Fenstermaker.
  • The vault may be a variation on the Milgram experiment on obedience to authority figures. The experiment involved assessing to what extent participants would violate their own morals when given an order from an authority figure. The commands telling you to sit in the chair in the sacrificial chamber are clearly patterned after the ones used in the Milgram experiment:
Vault 11 Milgram experiment
Welcome. Please sit in the chair. The show is about to begin. Please continue.
The show requires that you sit in the chair. The experiment requires that you continue.
It is absolutely essential that you sit in the chair. It is absolutely essential that you continue.
You have no other choice. You must sit in the chair. You have no other choice. You must go on.
  • The actions that took place in Vault 11 may also be inspired by the short story The Lottery by Shirley Jackson. In the story, a lottery is held annually, and the person who "wins" is stoned to death. The stoning is also to ensure the prosperity of the community.
  • The sacrifice sequence in the vault is very similar to the euthanasia scene in the film Soylent Green.
  • The poster with the slogan "I Hate Nate" is a reference to U.S. President Dwight D. Eisenhower's "I Like Ike" campaign.
