Vault 11

 is one of the Vault-Tec Vaults, located in the Mojave Wasteland. The entire Vault has been plastered with propaganda for an election for a new Overseer. The election seems to be unusual in that 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. At the conclusion of the term of an Overseer, they are required to enter a chamber below the Overseer's Office to offer their own life, otherwise the computer controlling the Vault will execute the entire population. The computer does not require that the sacrifice be the Overseer; of the original residents, only the Overseer entered the Vault cognizant of the regular sacrifices that would be required to provide life and shelter for the remainder of the Vault's residents. The residents of the vault, in their shock and anger at the discovery after having already been sealed inside the vault, demanded that the sacrifice be chosen democratically, and, further, chose the Overseer (who they viewed as having betrayed them) as the first sacrifice. This would marry the positions of Overseer and Sacrifice until the end.

In this Vault, several groups of voting blocs appeared to exercise power by means of their population and voting potential to exert force over other Vault residents. Prior to the final election, the most powerful of the voting blocs (the Justice Bloc) confronted Katherine Stone, threatening that, if she did not perform sexual favors for the members of their bloc, they would nominate her husband, Nathan Stone, for Overseer. Katherine, fearing for the fate of her husband, complied. Much to the shock of the Stone family, the Justice Bloc nominated Nathan for Overseer regardless, being the only Bloc to nominate him (it appears that it would be normal politics for several blocs to nominate a candidate due to the general moral outrage against a candidate).

Fearing for the fate of her husband, 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. Upon her capture, she confessed to her crimes immediately, explaining not only her plan but also her reasoning. She was asked if the voters would be so easily swayed, and explained she felt she would win because the voters had to make a choice "they could live with" the guilt of electing.

Katherine Stone's first act as Overseer, Overseer Order 745, dissolves the election process, instead decreeing that the position of Overseer will 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 elected, but also worried that waiting for a member of their own Bloc to be randomly chosen as Overseer to be elected and thus be able to reverse the order may take so long that the dissolving Vault social structure would not place them on top when it re-formed. They decided to stage an armed coup to force Katherine to reverse Overseer Order 745.

Below the Overseer's Office is a long tunnel leading to a room with a projector and a chair. Pleasant scenes are shown while a voice reassures the sacrifice that they lived a good life and their next one will be better yet. The door locks as soon as the projection starts, and when it's done, the walls open up to reveal Security Droids, Turrets, and Robobrains. If defeated, the player can then access a small room with the vault mainframe computer inside. This computer unlocks the door and reveals that there were only 5 survivors of the vault when they chose to stop sending sacrifices. There is also a recording that is likely played when they refuse. It states that by not sending a sacrifice, they are "a shining beacon to humanity" and they will not be killed. They are also informed that the vault door is then unlocked so they can come and go as they please.
