Vault 34

Vault 34 is one of the Vault-Tec Vaults.

Background
As part of the Vault Experiment, the armory was overstocked with weapons, ammo and not provided with a lock (although an Overseer's log says he had a lock installed on it after a riot). It was also equipped with a great amount of recreational facilities (such as a full-sized swimming pool), but at the cost of living space. The location of this Vault is in the Mojave Wasteland. By 2281, it still has people living in it, although they have become Feral ghouls. They are, however, still able to speak with some level of intelligence. While in combat they may shout words like 'pain', etc (other ghouls have been observed speaking in combat outside of the Vault, whether they are from Vault 34 or not is unknown). There are still a few non-ghoulified Vault dwellers remaining, being trapped somewhere within the ruins.

According to the Boomers historian Pete they used to occupy the Vault 34, but they got sick of not being allowed to use their weapons so they left and started a community at Nellis.

According to various terminals inside the vault, Vault 34 suffered overpopulation at some point, which the Overseer wanted to "fix". For obvious reasons, the Vault Dwellers revolted, attempting to riot and gain control of the armory. During the riot, the vault's reactor vents were damaged, which combined with the flooding caused by a bomb detonating in the Vault's pool, doomed the inhabitants to a lethal dose of radiation.

Preparing to enter the Vault
Both the entrance to the vault and the whole vault are very radioactive. The radiation of 1 RAD per second is constant, therefore, it is advisable to bring a lot of Rad-X and RadAway, and also consume Rad-X when entering (to increase your Radiation resistance . Note that there is a lot of Rad-X and RadAway in a safe (average difficulty) on the first level of the Vault. There are also many ghouls present in the Vault (all named Vault Dwellers or Vault Security Officers), which usually drop some ammo (10mm mostly), and sometimes a consumable item (Med-X, RadAway, Hydra...).

Layout
This vault is set up like most other vaults in the Mojave, though the multiple levels within this vault are connected by the main elevator. This Vault is still unexplored and information is obtained through a terminal on the 1st Floor/Entrance.

Vault 34 Entrance
The entrance to Vault 34 connects the vault to the Mojave Wasteland. This section consists of:
 * Natural rock to the Mojave.
 * Entrance
 * Control Booth containing Overseer's Journal Fragment
 * Atrium. There is a room (Office, but not Overseer's Office) on the upper level of the atrium containing a terminal with information on the 2nd floor flooding and the malfunctioning generator. It also has a fragmented message talking about riots and the armory being closed.
 * Main
 * There is an alternate entrance located on top of the hill right above Vault 34. But you can only get in there, not out.

Overseer's Office
To get into the Overseer's office, two terminal passwords must be found in the Vault (or, alternatively, you can hack the terminals - requires Science 100 skill - but nice for EXP if one prefers). The security terminal password is in the first flooded area, on a dead Glowing One/vault technician under a desk, and the utility terminal password is through the clinic and into the next flooded area, on the right, on another vault technician.

After finding the passwords, go to the door just before the entrance to the armory (this is the Utility Room), and activate the pump system on the terminal. Next, in the once-flooded area (Which now is behind a closed door -labeled Security Station A- 2nd door on your left after you make a right out of the utility room) where the utility terminal password was, use the security terminal to unlock the door to the Overseer's quarters. Finally, go to the Overseer's office (where the Overseer can be located, along with two automated machine gun turrets and alot of ghouls), obtain the Overseer's Password from his body after killing him, and use his terminal in order to unlock the armory. Alternatively, finding the terminal passwords can be avoided altogether, but requires a Science skill of 100.

Also, when you are in the medical bay area, look for a wall safe in the northeast corner. it contains various rad-away and rad-x (depending on level or spawn)

2nd Floor
Lots of Glowing Security Guards and other Feral Ghouls. Lots of 10mm SMG's and Pistols.
 * This is actually just the 3rd level of the 1st Floor. The 1st Floor has 4 levels (the 4th is initially flooded until you activate the pump system).

3rd Floor
This floor is inaccessible due to severe flooding on this level. but if you quickly swim to the pile of rubble you will find a dead Vault Technician under a desk on the left side with a key card. Near the dead Vault Technician is a locker containing a Vault 34 jumpsuit. (Alternatively, you don't have to worry about swimming fast if you acquired a rebreather from Nellis Air Force Base.)
 * NOTE: This is actually just the 4th level of the 1st Floor. It is initially flooded until you activate the pump system.

4th Floor
This floor contains Vault 34's damaged generator and is flooded by intense radiation. The generator area is accessible via the stairway in the Overseer's office, through the flooded tunnels. To unlock the generator door, use the terminal on the wall to the right of the door. Inside the generator room, another terminal gives you the option to destroy the generator to help the Sharecrop Farmers outside of New Vegas (gives NCR reputation) or to reroute control of the computer system to the trapped Vault dwellers (they can be later located at Aerotech Office Park "Suite 300" and one of them, Horowitz, will speak to you) -- despite having been locked in the back corner of the vault for at least a generation? Either way, you will receive experience.

Bugs
Saving inside the Overseer's office will result in a corrupted game save. Clear the Vault but do not enter the armory, unlock the armory from the Overseer's terminal, or save within the Overseer's office. You may go into the Overseer's office but can not save inside. The Armory is completely off limits until a patch resolves the problem. (I encountered no such glitch on the Xbox360. It appears to have been solved as of the latest update, although it's possible mine was a unique case)

Found glitch where the vault technician under the desk has its inventory listed as [Empty]. 'Opening' the technician will show an empty inventory with no password. Could not solve problem via reloading.

If you have Rex as a companion and tell him to wait for you outside of Vault 34 (or even in other places, such as Novac), he will appear inside the Vault while you are fighting (and probably die).

Two Great Khans spawned outside the entrance to the armory.
