The Vaults in the Fallout series are secretly experiments sponsored by the government and Vault-Tec to see how people react to different situations in a controlled environment. If they were meant to prove that doing crazy experiments on people makes them crazy, then congratulations all round. Especially in the case of these six Vaults of dubious scientific merit. Take Vault 11 as an example. After the door closed, the inhabitants were told by their overseer that they would have to sacrifice one of their fellow Vault dwellers each year or everyone would die. Thanks for that, overseer. Guess who was the first sacrifice. After this, whoever held the position of overseer was always the one chosen for sacrifice, so elections for overseer became ruthless, cutthroat affairs which eventually lead to blackmail, murder and finally civil war that killed all but five inhabitants of the Vault. It also turns out the Vault 11 experiment was actually to test morality against self-preservation. All the Vault dwellers needed to do was to refuse to sacrifice anyone and the whole thing would be over. Dick move, Vault-Tec. Still, at least those five people survived unharmed and uncrazy, right. Actually, four of them shot themselves out of shame. Good work, everyone. Outside Xbox brings you daily videos about Xbox 360 games and Xbox One games.
