Bethesda has ended its fight against Warner Bros over the Westworld mobile game.

The Fallout developer filed a lawsuit against the media company last June, claiming that Warner Bros Interactive Entertainment’s licensed Westworld game bore a remarkable similarity to Bethesda’s own Fallout Shelter. It went as far as to call the title a "blatant rip-off".

Key to the accusations were that developer Behaviour Interactive had worked on both Fallout Shelter and Westworld.

Bethesda claimed Behaviour used copyrighted code and trade secrets to speed up development of the latter title.

Both Fallout Shelter and Westworld involve managing a cutaway facility, be it a bomb shelter or sci-fi theme park. There were allegedly coding similarities between the two games including an unfixed Fallout bug seemingly also appearing in Westworld.

At the time Warner Bros struck back at the lawsuit, calling the accusations “baseless”.

Now, however, it appears the two companies have reached a settlement. Warner Bros Entertainment is not explicitly named in Bethesda’s statement, but it is highly likely the company is involved in the resolution.

"Bethesda Softworks and Behaviour Interactive jointly announced today that the parties have amicably resolved the lawsuit Bethesda brought against Behaviour and others related to the Fallout Shelter and Westworld mobile games," read a statement from Bethesda.

The terms of any settlement have not been disclosed.
