The series is set during the 21st, 22nd and 23rd centuries, and its atompunk retrofuturistic setting and art work are influenced by the post-war culture of 1950s United States, with its combination of hope for the promises of technology and the lurking fear of nuclear annihilation.

Fallout Online is a cancelled massively multiplayer online game (MMO) set in the Fallout universe that was being developed by Masthead Studios and was to be published by Interplay, with members of the Interplay team providing creative control and design.

Interplay's rights to develop and publish this game have been the subject of legal disputes between Interplay and Bethesda Softworks, the current owner of the Fallout franchise.
