Vault 81 ™ #3276716
Description
-|WELCOME TO VAULT 81|- Accepting new Dwellers. Vault-Tec created Vault 81 with the purpose of developing a single, universal cure for every sickness that humanity could possibly suffer from, using the residents as human test subjects. The vault was divided into two separate areas; the main vault, where up to 96 residents would make their home for the foreseeable future and the secret vault, where Vault-Tec scientists would conduct their research and observe the residents as they were unknowingly exposed to different diseases and cures. The diseases were released via propellant nozzles hidden within the resident's rooms. In the case of an evacuation of the vault all main vault residents were to be incinerated with the same propulsion nozzles.
