a vault led by an android designed to look Stalin, and act like Stalin, and everyone who disobeys orders is killed by the android Stalin, and his arms can turn into Gatling Cannons when someone gets executed, and basically, everyone must obey orders, and the overseer is so well-designed he can't be hacked, he can survive thousands of years, and defines indestructible (capable of surviving several direct impact nuclear blast), and there is no new overseer. no one can escape survive the tyranny of Robot Stalin. and the vault is designed so people can survive in the wasteland, but my guess is everyone (except the overseer) would be dead in 87 37 years after the vault closed. the vault would be sealed due to an accidental Intentional cave-in. the way to get killed is to say, "hate", "sucks", or "why"
