Bethesda is suing Warner Bros. and Behaviour Interactive for allegedly ripping off Fallout Shelter, according to the lawsuit filed on June 21. The suit, which was filed with the U.S. District Court for Maryland, seeks payment for damages and for Warner Bros. to cease sales of its Westworld game, which does look a lot like Bethesda’s 2015 game, Fallout Shelter.

“The Westworld game is a blatant rip-off of Fallout Shelter,” Bethesda claims in the lawsuit, which goes on to explain that Behaviour was hired in 2014 to develop coding in Fallout Shelter—coding that is allegedly being used in the new mobile game based on the popular HBO TV series. Behaviour using code for both games would, according to Bethesda, put the company in breach of its contract with Bethesda.

“Under the agreement, all Behaviour work product of any kind, including code, designs, artwork, layouts, and other assets and materials for Fallout Shelter were authored and owned by Bethesda ab initio as works made for hire,” states Bethesda’s lawsuit. “Working with the same copyrighted computer code used by Fallout Shelter, Westworld has the same or highly similar game design, art style, animations, features and other gameplay elements as Fallout Shelter, all of which are owned by Bethesda.”

Here’s footage of both games for comparison.
