"Industrial Junk
Ages ago, long before I was born, we lived underground. Everyone had guns but the overseer wouldn't let us explode anything, not even a hand grenade. We left and wandered the wastes. There were savages with knives. We blew them up with frag mines and grenades, burned them with flamethrowers.Pete, Keeper of the Story

Vault 34 is one of the Vault-Tec vaults located in the Mojave Wasteland.


As part of the Vault experiment, the armory was overstocked with weapons and ammunition. It was also equipped with a great number of recreational facilities, including a full-sized swimming pool, at the cost of living space. By 2281, it still has people living in it,[1] including Horowitz, although most of its residents have become feral ghouls and glowing ones. They are, however, still able to speak with some level of intelligence.

According to various sources inside the vault, the vault became overpopulated. Foreseeing problems, the overseer had a remote link to the armory lock installed on his terminal, denying access. A group of residents demanded access to the armory, stating the right to defend themselves, which the overseer denied. Rioting broke out soon after, and the group who had demanded access to the armory stormed the exit and left the vault.

Additionally, according to the Boomers historian Pete, the Boomers used to occupy Vault 34, but they grew tired of not being allowed to use their weapons so they left and started a community at Nellis. The fact that Pearl possesses the key to a gun case located deep in Vault 34 contributes to the credibility of this story.

The main exit was then sealed and guards posted to prevent anyone else from leaving. Years later, the vault started to experience problems with overpopulation, and the overseer proposed population control measures. This resulted in a portion attempting to overthrow the overseer, after which they unsuccessfully stormed the armory, damaging areas of the vault in the process; most importantly the reactor cooling vents, though also the main computer systems and other infrastructure. Consequently, the damaged reactor started leaking radioactive gases throughout the vault, and attempts to repair the reactor by the engineering team failed. Panic then set in. Whether by accident or design, the main exit could not be opened again, trapping the residents inside, their only hope being an automated unsealing of the vault in the near future or external intervention before they died from radiation poisoning.


Outside, just in front of the entrance, is a U.S. Army truck with radioactive barrels in the back and several golden geckos will spawn. The interior itself is unique among the vaults of the Mojave, having a much longer access tunnel appearing to be a natural cave, as well as a radically different layout. Moreover, the vault interior is highly irradiated. Precautions should be made to address rads accumulated while exploring, as the player will start to become irradiated upon entering Vault 34. In addition, be aware that a frequent theme in this vault will be new enemies appearing behind the Courier.

1st floorEdit

This section is comprised of the vault's long entrance tunnel, blast door, atrium, clinic, and a few apartments. Although this vault can feel a little like a labyrinth, it is mostly symmetrical in layout, although some halls have collapsed or been barricaded, forcing alternative routes to be taken. A flooded area along the western side contains the corpse of a glowing one which the game calls a 'Vault technician' under a desk. The corpse holds the Vault 34 security terminal password.

Vault 34 1st floor

The entry room is completely devoid of items, but an overseer's journal fragment can be found in the control booth. Most loot in this section is either in lockers or dressers, although first aid boxes are scattered about, as are 10mm pistols and 10mm submachine guns.

A medical center includes a broken Mark III Auto-Doc. It cannot be repaired by the player, but its diagnostic module can be used as one of the solutions for the quest Et Tumor, Brute?.

There is a terminal (Science 100) on the lower level, located in the Utility room, through the Clinic, which can pump the water out of one of the flooded areas. To activate the terminal without hacking, backtrack a small amount to the flooded area which will be on your right when facing the armory door. Straight down at the bottom of the pool is another dead glowing ghoul 'vault technician' under another desk with the Vault 34 utility terminal password. Use this on the computer in the Utility room to drain the water from that same flooded area and gain access to the Security Room.

In the room opposite the Utility room is another overseer's journal fragment. This level has access to the Armory and the Overseer's office.


Vault 34 reactor

This section has higher radiation than the rest, excluding the armory, as it contains the damaged reactor of the vault. At the end of the main hallway is a door to the flooded areas of the vault, which is inaccessible, and a small room containing a few security guards and a True Police Stories on the floor. The mutated overseer is in his office, standing on his raised desk with two turrets mounted underneath it. One of the overseer's journal fragments is in the room also. Be warned that upon entering the room, more ghouls will break through the inaccessible door labeled "Operations" and attack. Under the stairs is the lightly flooded engineering level, ending in the reactor chamber itself. The terminal next to the door is used to open it, and the terminal inside the reactor itself is required for the quest Hard Luck Blues. The overseer's window overlooks an inaccessible part of the armory.


Vault 34 armory

This is a small area that begins at a staircase and ends at a hallway. One way goes to a small common room with a reloading bench and a copy of Guns and Bullets by a couch. The other way goes to the armory, with a door that needs to be unlocked through the overseer's terminal before it can be entered. The armory is a small, two level room, with weapons and ammunition scattered around on the floor, tables and shelves. among other ammunition. The unique weapon All-American is found on an overturned table to the right side of the armory, and in a Very Hard locked footlocker, is the pulse gun. The upper gantry is inaccessible.

To access the armory you must get two passwords from two ghoul engineers that are in submerged areas. Then you must find two terminals, the first to pump out the water and on the second terminal an option will appear to open the overseer's door, then proceed to the overseer's office which is on the right of a hall beyond the newly unlocked door.

Once inside, you have to destroy the turret(s) and the ghoulified overseer and take his password from his corpse. Use the password to hack his terminal and open the armory door. Proceed to exit the room (if you are searching for the armory) and travel through the clinic. Eventually you will find the room containing many weapons (such as missile launchers, various rifles and SMG's) and the All-American Marksman carbine. Most of the weapons in the armory are in very poor condition but can be repaired with each other.

Security station AEdit

Vault 34 security station A

The door to this small area is underwater, but can easily be accessed when the water is pumped out. It contains a few security guards and a set of security armor. An overseer's journal fragment is found on the desk, next to the terminal which unlocks the overseer's quarters.

Notable lootEdit

Related questsEdit


  • The background music is "Industrial Junk", which was previously used for Junktown in Fallout and Gecko in Fallout 2.
  • The majority of the vault dwellers are not wearing Vault 34 jumpsuits. Instead, they wear the normal clothing of a feral ghoul. The exceptions are vault security, who appear to wear the remains of security armor. They do, however, occasionally carry the item.
  • When in the overseer's Office, the Armory is visible through the window. However, it is a separate area from the actual armory the player visits: feral ghouls exist in it, the only door into it leads to nothing, and if the player enters the room with console commands, the ammunition crates cannot be interacted with. However, the weapons on the tables can be looted.
  • There is an alternate entrance to Vault 34 cavern to the north-west of the usual entryway, on top of the rocky hill. The opening is near some radioactive waste barrels, and a golden gecko may be present. Jumping into the pit doesn't have you actually enter the cave, you just fall a few feet on top of a black void with dialogue to enter if you look down. If you fall in the pit area you can't jump out, so your options are either to enter the Vault or to fast travel.
  • The main vault door is so close to the wall it is actually out of its track and clipping through the floor grating, making it inoperable.
  • Ghouls will spawn as you enter certain rooms to ambush the player, usually in pairs.
  • The overseer is a feral ghoul reaver, who is directly assisted in his defense by two turrets.
    • If the overseer is somehow knocked out of the pedestal (with Ranger Takedown, Miss Fortune, etc), he may be flung back to his original position when getting back up.
  • Interestingly, the reaction of sealing the door to prevent more people from leaving seems utterly counterproductive given the vault's overpopulation problem.
  • Due to the use of scripted sequences that release more ghouls, companions are more vulnerable in this Vault than they are elsewhere. Since companions can see (but not kill) the hostile ghouls, they are treated as still being in combat, and thus won't autoheal until all the ghouls are dead. This can be remedied by going into a vacant section to allow them to recover.
  • This is one of the few Vaults that has no visible control panel to operate the vault door, despite it being opened manually before.
  • Chris Haversam was born in Vault 34, but left when he was convinced he became a ghoul after maintaining the reactor. Ironically, the reactor malfunctioned and turned the vault dwellers into real ghouls, which eventually resulted in them turning feral.
  • Several doors in this vault go up and down. You cannot interact with them. There are tables blocking them from closing so they just go up and down indefinitely.
  • None of the doors feature the number "34", but instead just feature a gold stripe.
  • When you talk to Boone while in the vault, he will say "Let's get out of this first.", but it will still open up the normal conversation menu.
  • ED-E may have trouble following the player throughout the Vault, due to the door frames being slightly lower than its height.
  • The door to "Operations" will not open when you reach the Overseer's office if you haven't also collected the 2 Vault 34 terminal passwords. However, if you go back and collect them after reaching the Overseer's office, the door will open immediately.
  • If one uses noclip to clip through the wall to see the vault door, the door does not feature the number 34. Instead, the vault door is blank.


Vault 34 was first mentioned in the Fallout Bible and appears only in Fallout: New Vegas.
