Vault 81

Vault 81 is one of the vault series of fallout shelters developed by Vault-Tec. This vault is located in Massachusetts.

Background
Vault 81 is unlike almost any other known vault, still containing sane and active dwellers. After a simple quest requiring 3 fusion cores, the player character can gain entrance and meet the vault dwellers.

Vault-Tec created Vault 81 with the purpose to find a cure for every sickness that humanity could possibly suffer from. There was the (still existing) living-part of the Vault where the regular population lived and another monitoring area containing 3 scientists and a Mrs. Handy called Curie. The scientists held mole rats in captivity as lab rats to research cures for diseases and regularly infiltrated a virus into the populated part of the vault to infect the vault dwellers. After a mole rat breakout and the death of the three scientists, the experiment couldn't be continued and the project was forgotten.

After the discovery of the secret part of Vault 81, Austin became diseased by one of the mole-rats from the experiment and the Sole Survivor steps into the forgotten part of the vault to get the cure from Curie.

Layout
It is equipped with advanced security features, such as security turrets directly outside the vault door and a screening area to make sure anyone entering the vault has no weapons or dangerous materials. There are also many security guards present inside the vault who patrol the hallways at all hours.
