Vaults
This page contains the Locations of and the loot found in the 5 Vaults in Fallout 4's Commonwealth, as well as related Quests. Vaults are bunkers built before the Great War to house communities that could survive the onslaught of a nuclear war. Many vaults were built across the Unites States and were hidden in all kinds of areas. Vault-Tec, the makers of these safehouses, often secretly installed psychological or social experiments within the vaults without the inhabitants knowledge.
These experiments included vaults with specific ratios of genders or specific types of inhabitants. At times purposely faulty equipment, food amounts, cloning technology, and more were implemented to influence results of the experiment.

Vault 111
Vault 111 is the first vault you visit in Fallout 4, where the game's protagonist begins their journey. The sole survivor is sent to this vault and put in a cryogenic sleep state for 200 years.
After the events of the Great War, Vault 111 is one of few locations to remain relatively untouched by both nuclear fallout and the surviving populace above. Vault 111 had a secret experiment done to inhabitants who sought refuge on the day the bombs fell.

Dwellers were placed in what they thought were sterilizing pods to prepare them to move further into the Vault, but were actually frozen in cryogenic stasis for Vault-Tec to study the effects of cryogenic hibernation on humans.
Notable Loot
- Cryolator
- Vault 111 Jumpsuit
Vault 114
Vault 114 was built for housing high ranking members of the government, local luminaries, and their families as part of a social experiment. The aim for the experiment was to find someone with no supervisory or government experience, and a strong anti-authority bias. Members of the Vault were made aware that they would live only with others of Boston's upper class. This sense of luxury changed over time as inhabitants shared living quarters and share amenities.
The Vault 114 staff personnel were instructed by Vault-Tech to disobey the instructions of the chosen Overseer during the duration of the experiment, even encouraged to push things to the point of discomfort and embarrassment to residents.
Notable Loot
Vault 75
Vault 75 was intended to be a safe place for children at Malden Middle School school to take cover in the event of a nuclear event. At the start of the Great War, children along with their families and teachers entered the Vault and were separated.
While the children were escorted to the atrium section, all of the adults were killed by the Vault 75 security. The goal of this action was to enhance the gene pool of the residences and create stronger, more intelligent people. The mission for those assigned to the Vault was the refinement of human genetics, where everyone deemed useless was killed before reaching the age of 18.
Vault 75 also serves as a stronghold for groups of Gunners during the events of Fallout 4. The original residents were emptied some time beforehand, due to a possible revolt by the residents inside.
Notable Loot
Vault 81
The true purpose in the creation of Vault 81 was the development of a universal cure for every sickness known to humanity. Residents of Vault 81 were regularly used as human test subjects for experiments in achieving this goal. The Vault itself could hold up to 96 residents inside, but an additional section of the Vault was made in secret for Vault-Tech scientist to observe inhabitants inside.
Vault-Tech scientist would expose various diseases to Vault 81 inhabitants, as well as cures to observe and record their effects. During the Great War, only four scientist were sealed inside with the residents and planned to continue with their experiment. However the Overseer of the Vault, Dr. Olivette, decided to deactivate the disease/cure distribution system and sealed off the secret section of the Vault, trapping the scientist inside and sealed away from the residents of Vault 81.
The scientist continued their experiments on mole rats instead of humans while trapped inside. Eventually the scientist died of old age within the secret section of the Vault, while the residents of Vault 81 continued living their daily lives until Vault 81 was finally opened again. Before this time however, one scientist sealed in the secret section had modified a Mr. Handy robot and created Curie.
Notable Loot
Vault 95
Vault 95 was designed to house individuals who were addicted to drugs. The Vault would offer addicts a chance to be rehabilitated and sheltered from nuclear fallout. Isolating and not providing drugs to residents was used to help eliminate chances of relapse and being self destructive.
Some terminal logs imply that this part of the experiment was a success and eventually the residents were able to overcome their addictions. According to terminal logs, one resident of Vault 95 claims the Vault fell into chaos after a stash of drugs was found hidden within the Vault. The fighting and killing was severe enough that is caused the residents to revert back to their former addictions.
All of the residents soon after died in the aftermath of these events, leaving the Vault itself abandoned. During the events that unfold of Fallout 4, Vault 95 is inhabited by Gunners that take refuge inside.
