Bethesda Softworks is suing Warner Bros. and Fallout Shelter co-developer Behaviour Interactive over the recently released Westworld, alleging that the mobile game based on HBO’s TV series is a “blatant rip-off” of Fallout Shelter.
In a suit filed in a Maryland U.S. District Court, Bethesda alleges that Westworld — developed by Behaviour and released this week for Android and iOS — “has the same or highly similar game design, art style, animations, features and other gameplay elements” as Fallout Shelter.
Fallout Shelter was originally released in 2015 for mobile devices.
Bethesda said in its suit that Behaviour uses “the same copyrighted computer code created for Fallout Shelter in Westworld,” alleging that a bug evident in an early version of Fallout Shelter (which was later fixed) also appears in Westworld.
Bethesda alleges the companies “copied Fallout Shelter’s features and then made cosmetic modifications for Westworld’s ‘western’ theme.”.
The suit points out similar gameplay features, including “cartoonish 2D characters in a 3D environment” and the underground multi-room facilities that players explore and build, in both Fallout Shelter and Westworld.
