Just last week, Bethesda took legal actions against Warner Bros because of the similarities between Bethesda's Fallout Shelter and their Westworld mobile game. It didn't take long for Warner to strike back at these claims.

Warner stated that they've been "assured by the game developer, Behaviour Interactive, that Bethesda's allegations are untrue and that none of Bethesda's code was used in the Westworld game. Moreover, contrary to Bethesda's baseless accusation, Warner Bros. at no time 'induced' Behaviour to use the Fallout Shelter code in Westworld" .

Warner Bros also added that the assertions by Bethesda Softworks that Warner's Westworld mobile game improperly used source code from Bethesda's Fallout Shelter are as surprising as they are unsubstantiated".

We will be following this situation closely.
