Fallout 2 PC game

The background story of Fallout involves a 'what-if' scenario where the United States tries to devise fusion power resulting in a hegemonic United States that has less reliance on petroleum. However, this is not achieved until 2077, shortly after an oil drilling conflict off the Pacific Coast pits the United States against China. It ends with a nuclear exchange resulting in the post-apocalyptic world the game takes place in.

The protagonist of the first game is a descendant of those that managed to find solace in government contracted fallout shelters known as the Vaults. The year the game takes place is 2161, somewhere in Northern California in Vault 13. In it, the Vault's Water Chip, which controls the water recycling and pumping machinery for the vault, has malfunctioned. This results in the player character being selected to leave the vault with minimal supplies, a handgun and a small amount of ammunition to find a new water chip. Eventually, the main character learns of a graver threat to not only his vault, but the rest of civilization.

The second game takes place 80 years after the first. It tells the story of the original hero's descendant and his or her quest to save their primitive tribe from starvation by finding an ancient environmental restoration machine known as the Garden of Eden Creation Kit.
