|Fallout is a franchise of post-apocalyptic role-playing games created by Interplay Entertainment, subsequently purchased by Bethesda Softworks, which has owned the franchise since 2007. The first cohort of titles were released under the Interplay banner, including Fallout, Fallout 2, Fallout Tactics, and Fallout: Brotherhood of Steel. After acquiring the franchise, Bethesda shifted the series to a 3D graphics and real-time combat style entirely, replacing the 2D isometric graphics and turn-based combat of some previous installments. Over the next 15 years to the current day, Bethesda has published four main titles including Fallout 3, Fallout: New Vegas, Fallout 4, and Fallout 76.
Originally envisioned as a sequel to Wasteland using Steve Jackson's GURPS, Fallout eventually matured into something entirely its own, a mature post-nuclear setting with a retro-futuristic aesthetic, powered by the originally home-brewed SPECIAL system. Its unique visual identity draws on countless sources, from 1930s Art Deco, through 1950s Americana, to 80s and 90s classics like Mad Max or The City of Lost Children.
The series also encompasses several spin-offs from the main role playing titles, including award-winning simulation game Fallout Shelter and several tabletop games including Fallout: The Board Game, Fallout: Wasteland Warfare, Fallout: Wasteland Warfare Roleplaying Game. In July 2020, it was confirmed that Amazon Studios had licensed the rights to a television series adaptation of the games. Kilter Films, in association with Bethesda Game Studios and Bethesda Softworks, will lead development.
