Vault 75

Vault 75 is a Vault-Tec Vault located in the Commonwealth.

Background
Located underneath the 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 war began in 2077, the children with their designated families and teachers entered in time. While all of the children were escorted to the atrium, the adults were separated and killed by Vault security. The purpose of this Vault was to enhance the gene pool of its selected residents to create stronger and more intelligent subjects. The surviving children were tested mentally and physically as part of the experiment. The children 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 18 or those with good intelligence and obedience were recruited to the vaults science team after graduation. The others who were deemed insufficient to the vault's standards were killed upon reaching the age of 18 prior to 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 amongst the junior test subjects, aided by a "graduate" scientist. Whatever the case, in 2287 there are no residents remaining, and the Vault is serving as a hidden Gunners stronghold. If the Sole Survivor chooses to side with the Railroad or the Institute (eliminating the Brotherhood of Steel), there will be BoS soldiers also in the vault, fighting the Gunners and Sole Survivor for control of the Vault. But if the Sole Survivor chooses to side with the Brotherhood of Steel (eliminating the Institute), there will be 2nd gen synths also in the vault fighting the Gunners with normally minimal success.

Layout
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 heavily populated with Gunners, but may be full of both the Brotherhood or synths and the Gunners in a battle within the vault. The Atrium consists of two floors; on the upper floor the player character will find a classroom, two dormitories and the entrance to the overseers office. On the lower floor of the atrium the player character will find the kitchen and canteen area. To the south there is a cave with the vault's power generators. Going through the corridors to the west from the atrium you will find a cave with a diner; this is a combat simulation area. The simulation can be activated using the terminal.

Notable loot

 * Science bobblehead, on the desk overlooking the subterranean "Diner" area, inside the vault building, basement level 3.
 * Grognak the Barbarian in the room just off the overseer's room (Expert pick or use the Overseer's terminal to unlock)
 * Overseer safe key in the room just off of the overseer's room (master pick or use the Overseer's terminal to unlock)
 * Overseer's safe is in the right-hand side of the Overseer's desk near the broken computer.
 * 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.

Appearances
Vault 75 only appears in Fallout 4.

Bugs

 * 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 cause by a misc quest pointing to the chems stash in the vault. On PC this may be fixed by spawning the required keys ( and ) to allow further progress; the quest may be added and completed automatically when leaving the vault.
