Warner Bros. has responded to the legal challenge from Bethesda Softworks. Last week, Bethesda filed suit against Warner Bros., calling the recently released Westworld mobile game a "blatant ripoff" of its own game, Fallout Shelter. In a statement, Warner Bros. acknowledges the similarities but says it is an original game and uses no source code from Fallout Shelter, as Bethesda alleges.

"As one of the world's leading creators of intellectual property, including the ground-breaking television series Westworld, Warner Bros. has a deep respect for intellectual property rights," the company said in a statement to GamesIndustry.biz. "As such, 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."
