In the 200 years since the global atomic war of 2077, the surviving residents of the Capitol Wasteland (formerly known as Washington, D.C.) have holed up in Vault 101, enjoying a life free from the dangers beyond. In the Vault, you are protected from the Giant Insects, Raiders, Slavers and Super Mutants that prowl the Capitol Wasteland. But now your father has defied the Overseer and left the Vault for reasons you don't know. You must find him and discover the truth before it is too late.
