Fallout 3, Vault-Tec engineers have worked around the clock on an interactive reproduction of Wasteland life for you to enjoy from the comfort of your own vault. Included is an expansive world, unique combat, shockingly realistic visuals, tons of player choice, and an incredible cast of dynamic characters. Every minute is a fight for survival against the terrors of the outside world - radiation, Super Mutants, and hostile mutated creatures. From Vault-Tec, America's First Choice in Post Nuclear Simulation. Vault 101 - Jewel of the Wastes. For 200 years, Vault 101 has faithfully 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 the constant stress of the outside world. Giant Insects, Raiders, Slavers, and yes, even Super Mutants are all no match for superior Vault-Tec engineering.
