Vault 22

 is a Vault-Tec Vault made before the bombs fell in 2077. The Vault door is opened, and creatures such as mantises can be seen outside. It is located south of Griffin Wares Sacked Caravan, east of Jacobstown an west from the Thorn.

Background
Vault 22 was part of an agricultural experiment that involved the growing of spores which eventually led to the mutation of the inhabitants of the Vault as well as dense vegetation. The mutation was distributed through the ventalation system. There were reports of noises in the vents, which turned out to be praying mantis', which have mutated over time. Due to the intense growth of plants the vault has been dubbed the "Jungle Vault". NCR soldiers have mentioned stories about the Vault throughout New Vegas. The Courier has the choice of doing a quest in which you explore Vault 22 to retrieve scientific data and research, while also looking for an NCR scientist who disappeared after she was sent to research the Vault.

Traveling through the Vault
Vault 22 is very similar to other Vaults a player may have visited during Fallout 3. A dungeon with narrow corridors, small rooms connected by the main lobby, and multiple levels. Once inside the dimly lit Vault, the player will encounter spore carriers and spore plants. The vault is broken up into five levels as follows: second level - Oxygen Recycling, third level - Food Production, fourth level - Common Area, and fifth level - Pest Control. The different levels can be reached by repairing the main elevator within the Vault (requires repair skill of 50 or more) or less efficiently, by staircase.

There is 6 HEPA 20 Cartridge Filters if you go through the caves and come out at the second level. Their use has yet to be discovered.

The key card to access the tunnels is located in the Crew Quarts in the first bedroom on the left side on a shelf just inside the door.

Access to the crew quarters is given via the Overseer's Terminal

Notable Equipment
The AER14 Prototype Laser Rifle is located here. To obtain it, go through the fifth floor, Pest Control, and enter the stairway door to the common area which has a very easy lock. The AER14 is laying on the ground next to a scorched skeleton.
