Fallout 3

Game Description: For 200 years, Vault 101, a fallout shelter, has served the surviving residents of Washington DC and its environs, now known as the Capital Wasteland. Though the global atomic war of 2077 left the US all but destroyed, the residents of Vault 101 enjoy a life free from Giant Insects, Raiders, Slavers, and yes, even Super Mutants. Yet one morning, you awake to find that your father has left the comfort and security afforded by Vault 101 for reasons unknown. Leaving the only home you've ever known, you emerge from the Vault into the harsh Wasteland sun to search for your father. Fallout 3 is a singleplayer action role-playing game that combines the horrific insanity of the Cold War era theory of mutually assured destruction gone terribly wrong with the kitschy naivety of American 1950s nuclear propaganda.
