Atom Shelter is the name for a series of Atomic Fallout Shelters currently under construction in the Federated States of America. Sparked by the threat of nuclear war between the United States and the Soviet Union, Project Safehouse was set in motion, which was designed to provide fallout shelters to the general public. As of 2012 over 150 atom shelters have been constructed by government defence contractor Atom-Tech. The project was funded by both Atom-Tech and the FSA government. Shelter numbering goes from 1-154 for Civilian shelters, and the Presidential shelter is known as Atom 0.
