Vault 34

Vault 34 is one of the Vault-Tec vaults, located southwest of Nellis Air Force Base in the Mojave Wasteland $$

Background
As part of the vault social experiment, the armory was overstocked with weapons and ammunition which shaped its culture. It was also equipped with recreational facilities, including a full-sized swimming pool, at the cost of living space.

The overcrowded conditions led to conflict, leading the overseer to have a remote link to the armory lock installed on their terminal. 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, while another group took advantage of vault security being distracted to ambush the armory. After the group left, the main exit was sealed and guards posted to prevent anyone else from leaving.

To address the ongoing overpopulation problem, the overseer proposed population control measures instead, which resulted in inhabitants attempting to overthrow the leader. They unsuccessfully stormed the armory, damaging areas of the vault in the process, such as the reactor cooling vents and main computer systems. The damaged reactor began leaking radiation throughout the vault, and attempts to repair the reactor by the engineering team failed. The main exit could not be opened again, trapping them inside, their only hope being future external intervention to unseal the vault.

Those who left in the initial uprising subsequently referred to themselves as the Boomers, having settled at Nellis over 50 years ago. The group's historian Pete tells the Courier that 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. Their leader Pearl still possesses a key to a gun case located in the vault.

Layout
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 is accessed by a cave tunnel, and the entire location is irradiated.

First floor
The first floor consists of a long entrance tunnel, blast door, atrium, clinic, and residential space. 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 vault technician glowing one under a desk, which holds the Vault 34 security terminal password.

An overseer's journal fragment can be found in the control booth. Most of the loot found in this section is located in lockers or dressers, although first aid boxes are scattered around, as well as 10mm Pistols and 10mm Submachine Guns. Several doors move up and down indefinitely due to rubble blocking the entryways, but cannot be otherwise interacted with. All doors in the vault feature a gold stripe instead of a vault number.

A medical center includes a broken Mark III Auto-Doc. It cannot be repaired by the player character, 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 this level, located in the utility room, through the clinic, which can pump 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 the right when facing the armory door. Straight down at the bottom of the pool is another dead glowing vault technician under a desk with the Vault 34 utility terminal password. This can be used on the terminal in the utility room in order to drain the water from that same flooded area and gain access to the security room. Opposite of the utility room is another overseer's journal fragment. This level also provides access to the armory and the overseer's office.

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 inaccessible flooded areas, and a small room containing security guards and a True Police Stories on the floor. One of the overseer's journal fragments is also found in this room.

More ghouls may break through the inaccessible door labeled "operations" and attack. Under the stairs is a partially 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.

Armory
This is a small area that begins at a staircase and ends in 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 through a door that needs to be unlocked with the overseer's terminal before it can be entered.

To access the armory, two passwords from two ghoul engineers that are in submerged areas must be found. Then a terminal must be used to pump water out of a flooded area and a second terminal will be used to unlock the overseer's door. The overseer is a feral ghoul reaver, who is directly assisted in defense by two turrets.

Once neutralized, the armory password is found on the corpse, which allows the terminal to be hacked and armory accessed by progressing through the clinic. The armory is a small, two-level room, with weapons and ammunition scattered around on the floor, tables, and shelves. 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. Most of the weapons in the armory are in very poor condition. The upper gantry is inaccessible.

A security station door is underwater, but can easily be accessed once the water is pumped out. It contains 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.

Loot

 * All-American - A unique Marksman Carbine, on an overturned table in the armory.
 * In the armory, there is a large stash of ammunition and weapons, including two Sniper Rifles, a Missile Launcher, a Minigun, three blocks of C-4, two Assault Carbines, two Grenade Launchers, one Marksman Carbine and a Riot Shotgun.
 * Pulse Gun - In a Very Hard locked gun case on the floor next to a table in the armory. Aside from being picked, the lock can also be opened with Col. Blackwell's key from Nellis Air Force Base.
 * Detonator - Located in the armory.
 * Guns and Bullets - On the small metal table between the sofas by the pool table, in the armory common room.
 * Seven Vault 34 security armors and seven helmets - Five sets can be found lying in the armory. One is also found in the room on the left, right after the 2nd flooded staircase, lying on a chair in a pile of rubble. Another one is located in security station A.
 * Four overseer's journal fragments can be found throughout the Vault.
 * Vault 34 utility terminal password and Vault 34 security terminal password - On Vault 34 technicians in flooded sections of the first floor.

Bugs

 * Just outside of the Vault's entrance, the golden geckos may become stuck inside of the U.S. Army truck.
 * Upon discovery of Vault 34, the related challenge of discovering the Vault is shown as "Find Vault 34 0/0".
 * Saving anywhere inside the overseer's office or the armory may result in a corrupted game save.
 * While in the armory, Great Khans may appear and can make the camera zoom in and freeze or slow down the game considerably. Two of the Great Khans will appear at the door to the armory and one at the top of the stairs toward the armory.
 * Occasionally exiting through doors on lower levels may cause the player character to return to the cave entrance after a loading screen.
 * Some clipping issues that may stick the player character while swimming in the room with the glowing one with the Vault 34 security terminal password. Directly above the roll-top desk, the player character may become stuck in the ceiling and will become unable to continue onward. Switching camera perspective repetitively may result in a fix.
 * Upon leaving the Vault, some companions may have vanished and/or their markers moved outside of the map.
 * If companions are told to wait at the top of flooded stairs in this area, they can become permanently stuck between doorways once the pump system is activated. A potential solution involves going into the third person and rotating until the option to talk to them and dismiss them comes up.
 * Sometimes the entrance will show as Vault 34, cloning cells.
 * Upon entering the armory, any companions that had disappeared without a trace may suddenly join the party (confirmed Rex, ED-E, Veronica and Lily).
 * There is an inaccessible room containing three ghouls. Companions may somehow enter this room and become trapped.
 * In the overseer's office next to the monitor there is a chance to "fall in" the water and become stuck "in limbo" off the map or between floors in the water. A save must be reloaded.
