Bethesda Softworks, the developer and publisher of Fallout and Skyrim, sued Warner Bros. in a US District Court in Maryland Friday, alleging that a new mobile game based on the HBO show Westworld rips off Fallout Shelter, Bethesda's wildly successful mobile game from 2015.

Warner Bros. only released the Westworld game Thursday, but the controversy has been brewing for a while. Ever since Westworld was announced back in April, the similarities between it and Fallout Shelter have been noted in dozens of articles about the new game.
