Fallout: Vault 29

The year is or was 2077, a past that is long forgotten to time. A retro-future somehow stuck in 1955 but still futuristic. This world is similar to our own, until 1969 when the United States broke up into 13 Commonwealths turning a great nation into a cesspool of unrest and political strife. Due to the rising issue of the cold war, the same nuclear science that brought WW2 to an end was used to advance AI and robotics. The microchip was never invented so everything was analog and fusion powered hence the retro-future look of the 50s. Things to have only be thought of in science fiction came to be, fusion powered robot butlers called Mr. Handys and Protectron robots used for medical and police uses a long with many others. But of course big corporations hid what was really going on from the public eye. One of these companies being Vault Tech. For years now they have been selling underground vaults to those who could afford it, those that couldn't lived in fear of the day a war broke out. By 2052 the world was running out of fossil fuels starting the Resource Wars. The US annexes Canada and invades Mexico and tries to keep China out of Alaska. Europe invades the middle east all fighting for the dwindling oil. In 2054 Project Safehouse is put into place and 122 public vaults to sell for safety from nuclear annihilation. Of course companies lie and each of these vaults were used for horrid experiments. This all leads us to the fateful sunny morning of October 23rd 2077, we no longer had to worry about resources but instead surviving nuclear fallout. In a matter of two hours the whole country was in ruin. Who pushed the button?
