Vault 108

Vault 108 is one of the Vault-Tec Vaults, located south-southeast of Canterbury Commons and northeast of Corvega Factory.

Inhabitants
The Vault 108 Entrance area is inhabited by a colony of several Mole Rats. The Vault 108 Living Quarters and Vault 108 Cloning Lab are inhabited by a dozen hostile clones named Gary.

The Radroaches, the Mole Rats and the Garys are all very low-level characters, making combat in Vault 108 very easy.

Experiment
In the Citadel Vault-Tec computer, the premise of the experiment was explained to study conflict for leadership and power in a vault. The Vault Overseer was known to have a genetic predisposition for a rare form of cancer that was expected to kill him within 40 months of the experiment's inception, and positions of authority in the Vault went undesignated and discretion given to the Overseer. The main power supply was also scheduled to malfunction after 240 months (20 years while the vault was planned to be sealed for 30), and the back-up power supply was intentionally insufficient to meet the Vault's needs. On top of all this, the Vault was given three times the normal armory stock and no entertainment recordings.

As part of the Vault Experiment, the vault houses a cloning lab. It is full of hostile clones, all named Gary. Though the clones' role in the Vault experiment is unclear, they may have been created by one of the Vault scientists as a sort of personal army in his bid for power. This would explain their hostility to any "non-Gary".

It could also have been that with the Overseer destined to die soon after and the larger weapons stock than in other Vaults, that the people would have been observed and seen how they would have reacted in the possible resulting power vacuum, or to claim positions they felt were rightfully theirs if they had not been given them, with no entertainment tapes to distract the dwellers it would have led to a breakdown of relationships between people much faster. The Gary's could possibly have factored into this as part of the experiment to see if the Vault Dwellers could put aside their differences and unite against a common threat. Of course this is just speculation.

With the exception of Gary 1 and three other random Garys, all other clones initially use melee weapons. Their AI, however, may direct them to pick up stronger weapons.

History
There is a Holodisk found in the Cloning Lab (A on map) (located near a body near one of the examination tables, this room also has a Very Easy Safe in it as well as Gary 12 and 36) that slightly explains the fate of Vault 108. Every time Gary was cloned, it immediately became hostile to non-clones, with each one becoming more violent. After the 53rd was no different, they began to wonder what to do with all of the clones, as the Vault's observation rooms were becoming full. The other entry in the holodisk says that Gary 54 was the same way, having injured a Doctor Peterson during an examination.

The entry also states that they will be destroying some of the clones, to make room for "many more tests." What happened next is not clear; possibly the Gary clones overpowered those tasked with destroying them and slaughtered the rest of the Vault's citizens. Given the possible division of the vault citizens into factions after the death of the overseer, it is also possible the vault citizens were unable to provide a united response to counter an armed mob of insane clones.

It is highly possible that a few of the Gary clones have escaped Vault 108, seeing as how the door is opened when discovered, and how a recently dead Wastelander is found on an examining table in the cloning lab and Gary 23, who is found in an Outcast outpost in Arlington in the Operation: Anchorage expansion. The Gary clones might not be as unintelligent as some had thought of them to be.

Through entering the Vault, a player may stumble upon a pile of skeletons (former Dwellers) and a the body of a Gary. It is likely that he died recently, maybe only days before the player enters Vault 108. Perhaps this passage is where the other clones stack their dead.

Entrance

 * A Stealth Boy can be found in the entrance, between two terminals that are just to the right of the door to the Living Quarters (to the right, if you are facing the door).
 * A Silenced 10mm Pistol can found in the entrance, on the floor in front of the door to the living quarters
 * A Nuka-Cola Quantum can be found behind some crates in a narrow room in the Entrance area, to the east of the door to the cloning labs.
 * An apparently inaccessible Tumblers Today can be seen on the floor below a step ladder behind some crates near the SE corner of the entrance level. This is a glitch of the physics engine. It's in the same room/location of the Nuka-Cola Quantum. It possibly can be made accessible through the extensive use of explosives.

Living Quarters

 * There is a Pugilism Illustrated in the Living Quarters, on the counter in the cafeteria.
 * There is a Sugar Bombs in the refrigerator on the same side of the cafeteria as the Pugilism book.

Cloning Lab

 * Bobblehead - Charisma - Located in the Vault Cloning Lab on a table in the observation room (located in the center of the map), which looks into the main operating room. If you get lost, go to the black operating tables (one should have a skeleton on it) and look through the glass into the observation room (or the room with four beds). There you will see the bobblehead on a table beside a microscope.
 * In the Cloning Lab, on a different table in the same room as the Bobblehead - Charisma is a Lying, Congressional Style.
 * There is a set of random armor in one of the lockers in the top right room of the Cloning Labs and another set of random armor in another locker in the same room
 * The Holodisc in the cloning lab ("Cloning Log") that slightly explains the events of Vault 108 is in the room where there's a black cube safe that can be lockpicked. Look for a skeleton on the floor next to an examination table; the holodisc is close by.

Bug

 * The vault door may be found in the open position. There is a possibility that it may not be able to be closed. (confirmed all platforms)  Pressing on the actual vault door will make it close and open.
 * Two Gary's can be found having normal conversation dialog, if in sneak mode, and left unnoticed.

Behind the scenes

 * The idea of a character who can only say "Gary" is likely based on the Strangers On The Shore episode of Only Fools and Horses in which a character is only able to say the name given to him by the others, 'Gary'. As in Fallout 3, this includes altering his tone and inflection to convey various emotions through his "Gary"s.
 * This may also be a reference to Being John Malkovich in which John Malkovich encounters clones who can say only "Malkovich".
 * That the clones are identified by 'Gary' and then a number may be a reference to the Star Trek:TOS character Gary Seven.
