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.

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. Due to the intense growth of plants this 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 a disappeared scientist.

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.
