Bethesda and Warner Bros. confirmed that they've amicably resolved the lawsuit filed by Bethesda, which accused Behaviour's Westworld to be a blatant rip-off of their Fallout Shelter game. The exact terms of their settlement remain secret.
Back in June 2018, Behaviour Interactive and Warner Bros. over a mobile game called Westworld, claiming that it infringes on Bethesda's Fallout Shelter intellectual property. The publisher and developer claimed that Westworld is a "blatant rip-off of Fallout Shelter" and that Behaviour Interactive stole its design, artwork and code which allowed them to quickly create and publish the game.
For those who are unfamiliar with these games, Behaviour Interactive worked on Fallout Shelter and their deal with Bethesda was clear - they were hired to develop the game and its assets solely for use by Bethesda. However, Warner Bros. approached Behaviour Interactive to create their own mobile game based on the Westworld series, hopefully mimicking Bethesda's success with Fallout Shelter.
Ultimately though, Bethesda have managed to reach an agreement with Behaviour Interactive and Warner Bros. over the lawsuit. This has been confirmed by both Bethesda and Warner Bros. in a joint statement which says that companies "have amicably resolved the lawsuit Bethesda brought against Behaviour and others related to the Fallout Shelter and Westworld mobile games."
Additionally, the filing states that Bethesda dismissed its claims with prejudice, which in a nutshell means that the whole "rip-off story" is over and Bethesda won't be able to use the same allegations in court. The terms of the settlement remain unclear but for what it's worth - both companies have agreed to pay their own legal fees.
As much as we're glad the legal scuffle is over, we can't deny it wouldn't have been interesting hearing how Bethesda won the day thanks to a bug. Yes, a bug, since it turned out that Westworld sports a bug so specific to Fallout that it would've been impossible to replicate. Now that is one argument nobody can dispute - only Bethesda can do what Bethesda can do.
