Vault 75 is a Vault-Tec vault located in the Commonwealth in 2287.[1]

BackgroundEdit

Located underneath Malden Middle School, this vault was presented to the public as a safe place for children in the school to take cover in the event of a nuclear war. When the bombs eventually fell in 2077, every designated family with a student attending the school, along with the teachers, made it to the vault in time. Upon entering, the children were separated from their families and escorted to the atrium, while the adults were executed by security staff, under the guise they were receiving "orientation." This act of murder coincided with the purpose of the vault, which was to enhance the gene pool of its selected residents to create stronger and more intelligent subjects. The surviving children were harshly tested mentally and physically - bordering on torture, and without regard for the survival of weaker individuals - as part of the experiment.

They were raised learning about the horrors of "Uptopland," a nickname for the wasteland, and were told that they would be strong enough to venture out into the wastes and help the suffering people upon graduation. If they were intelligent and physically well built, they were either "harvested" for their good genes when they turned eighteen, or those displaying good intelligence and obedience were recruited to the vault's science team after graduation. The others who were deemed insufficient to the vault's standards were killed upon reaching the age of eighteen after a ceremony "celebrating" their graduation. However, details found in the various terminals suggest that even those who were "graduated" were killed after harvesting. The mission of Vault 75, above all, was the refinement of human genetics.

At some point, the vault was opened and emptied. Some internal log entries suggest there was a rebellion among the junior test subjects, aided by a "graduate" scientist. This is backed by the way the bodies are placed in the Vault, indicating a quick and merciless breakout. Whatever the case, in 2287 there are no residents remaining, and the vault is serving as a hidden Gunners stronghold.

LayoutEdit

The entrance is a standard vault entrance, accessible through the Malden School basement door from the wasteland. An elevator will take the player character down into the actual vault. Entering the elevator will activate the quest Vault 75. The entire vault is initially heavily populated with Gunners, although depending on the player character's choices in the endgame, other enemies will appear: Brotherhood of Steel forces will appear if the player character completes the game with the Railroad or the Institute, whereas synths will appear instead if the player character sided with the Brotherhood of Steel or the Minutemen.

The vault is divided into three sections, the common, lab, and admin area. To access the lab and admin area key cards are necessary to unlock the security doors. Downstairs is a combat simulation room, where you can use the terminal to initiate a combat training game and record your score online. This room also contains the Gunner commander that has a lab access card.

The admin section of the vault can be found deeper in the vault behind the sealed lab doors. Some of the doors that lead to the vault overseer room within this section require an admin access card, which can be acquired/looted from one of the enemies lurking within.

Notable lootEdit

  • Vault 75 lab access card - On the Gunner commander in the simulation area, or in the tool case next to him. Gives access to the lab section.
  • Overseer residence key - On the Gunner commander.
  • Vault 75 admin access card - On a Gunner in the lab area. Gives access to the admin section.
  • Science bobblehead - Accessible with the lab access card, in the same room as the Gunner holding the admin access card, on the desk overlooking the subterranean combat simulation area and the "diner." From the elevator, it's through the first lab access door on the right marked Security, then right again, up the stairs and all the way to the westernmost part of this floor.
  • Grognak the Barbarian issue #5 - In the room just off the overseer's room (Expert pick or use the overseer's terminal to unlock)
  • Vault-Tec lunchbox - On the lower level. Immediately after exiting the elevator, look left at the intersection behind the blue container. There is a skeleton wearing glasses and holding it.
  • Overseer safe key - In the room just off of the overseer's room (the safe has a lock with a Master difficulty or one can use the overseer's terminal to unlock the safe).

NotesEdit

  • Vault 75 does not have an external terminal to open the vault door from the outside.
  • Fast traveling to Vault 75 after the cell has refreshed may place the Sole Survivor directly on top of a fragmentation mine.
Gary-Vault-75

Gary's easter egg inside Vault 75.

  • There are three instances of four wooden blocks arranged in the name "Gary," a reference to Gary clones from Vault 108 in Fallout 3; One in the western residential room on the mezzanine floor, another under the open vault door behind some crates and one more in a cabinet inside one of the children's dorm rooms.
  • The chief scientist's terminal references Stanislaus Braun from Vault 112.
  • The chief scientist's terminal states that the most recent graduation was scheduled for 999.66e33 days ago. This is either a mistake or a glitch in the terminal, as this would equal 2.73879452054794502e33 years (2,738,794,520,547,940,000,000,000,000,000,000 years) or just over two and a half decillion years.
  • When one participates in the combat simulation in Vault 75 their name and time will be recorded on the terminal in the same room.
  • If one has already completed the game with The Institute, or the Railroad, there will be a battle between rogue BoS soldiers and the Gunners taking place in Vault 75. Similarly, if one completes the game for the Brotherhood or Minutemen, there will be a battle between synths and Gunners.
  • If one has not completed the game with any faction, but has started a faction quest to destroy BoS for example, the fight between Gunners and BoS will also be taking place here.
  • Vault 75 along with Vault 95 are the only two vaults that do not have obtainable Jumpsuits.
  • When at this location companions make comments, these comments are activated at two locations: the entrance and in the combat training room.
Location comments
Character Specific location Comment
Cait entrance "Well, I'll be damned. Another vault."
combat training room "I love what they've done with the place."
Codsworth entrance "Vault-Tec certainly made some odd location choices. Although in this case, they could be guarding the future."
combat training room "Curious. It's a replica of the surface. I wonder what it was used for."
Curie entrance "My Vault had us conducting secret experiments on the residents. Perhaps the same is true for this one."
combat training room "Some sort of training ground... yes?"
Danse entrance "I hope the schoolchildren that occupied this building weren't forced to live out the rest of their days in this vault."
combat training room "It's a training yard. Was Vault-Tec training their own private army?"
Deacon entrance "I thought there was a Vault in the area."
combat training room "Deja vu. We are still in a vault, right?"
John Hancock entrance "Hello."
combat training room "This really what they thought the world would look like? Not bad, actually."
Robert MacCready entrance "In the basement of a school? Vault-Tec was running out of ideas."
combat training room "The only thing missing from this playground is the radiation."
Nick Valentine entrance "What have we here."
combat training room "Now this feels like home."
Piper Wright entrance "Is that what I think it is?"
combat training room "This is just creepy."
Preston Garvey entrance "I wasn't expecting to find this here."
combat training room "If they'd just waited until after the war, they wouldn't have needed to go to all the trouble of building this."
X6-88 entrance "This was well-hidden."
combat training room "A training area of some kind. Not bad."

AppearancesEdit

Vault 75 appears only in Fallout 4.

BugsEdit

PCIcon pc Playstation 4Icon ps4 Xbox OneIcon xboxone It is possible that the quest does not trigger upon entering Vault 75, therefore causing the key cards not to spawn and making the Science bobblehead unobtainable. This may be caused by a misc quest pointing to the chems stash in the vault. On PC this may be fixed by spawning the required keys (001a58a2 and 001a58a6) to allow further progress; the quest may be added and completed automatically when leaving the vault or the quest may trigger when leaving the admin area and completed upon accessing the Overseer's terminal. This can also happen even if you got the "Search for Caps in Vault 75" miscellaneous quest.[verified]

  1. Fallout 4 Vault Dweller's Survival Guide p. 288: "According to some uncorroborated reports, Vault-Tec was commissioned by the U.S. military to experiment on and train children to become battle-ready super-soldiers who would obey orders without a second thought. The experiment did not end well. Gunners have moved into what remains of the vault. If you are currently allied with the Brotherhood of Steel or the Institute, expect to encounter allied forces battling Gunners at this location. The entrance to the interior is located behind a cell door (watch for the trap) at the southern corner of the building."
