Bethesda is suing Warner Bros. over the recently released Westworld mobile game, alleging that it shares several similarities with its mobile management simulator Fallout Shelter.
In the lawsuit which you can find over at Polygon, Bethesda is claiming that developers Behaviour Interactive used the same code found in Fallout Shelter, a title they were contracted to co-develop back in 2015.
Westworld launched on iOS and Android last week and is currently featured on the iOS App Store with a positive rating of 4.6/5 from over six thousand players.
Both games are certainly cut from the same cloth, with Fallout Shelter dropping the player in the shoes of an Overseer, managing a vault full of denizens with varying needs.
The Westworld mobile game has you controlling your own DELOS park, managing the precarious hosts from the popular HBO TV series and expanding your operations with upgrades and buildings.
One of the key pieces of evidence employed by Bethesda within the lawsuit is the existence of a Fallout Shelter bug in the Westworld mobile game. A bug that skews the in-game camera and pushes it out of focus was found in the Westworld mobile demo. This same issue was fixed in Fallout Shelter prior to its release.
The company is seeking damages for copyright infringement and wants the game removed from mobile storefronts, alleging that Behaviour Interactive “utilized its restricted access to Bethesda’s intellectual property” by using the Fallout Shelter code, which is in breach of a pre-established contract.
Commenting on the lawsuit to Variety, Bethesda stated that the game is a “blatant rip-off” of Fallout Shelter “with largely superficial, cosmetic changes.”
Warner Bros. and Behaviour Interactive are yet to comment on the lawsuit.
