Fallout

The first of the Fallout series. It was created after Wasteland by Interplay. Fallout wasn't involved with Bethesda at this point in the franchise.

The game is set in a post-apocalyptic world following the Great War, a nuclear war that occurred on October 23, 2077 and lasted less than two hours but caused immense damage and destruction. Before The Great War came the Resource Wars, during which the United Nations had disbanded, a plague rendered the United States paranoid and Canada was annexed. The game takes place in 2161, 84 years after the Great War in Southern California and begins in Vault 13, the Vault Dweller's home. Vault 13's water chip, a computer chip responsible for the water recycling and pumping machinery, has broken. The Vault Overseer tasks the protagonist with finding a replacement. They are given a portable device called the Pip-Boy 2000 which keeps track of map making, quest objectives, and various book keeping aspects. Armed with the Pip-Boy 2000 and meager equipment, the protagonist is sent out into the remains of California to find another water chip.
