A few years ago, Bethesda worked with Behaviour Interactive to release a management sim based on the Fallout franchise. It was fine. Then earlier this week, Warner Bros. announced a mobile management sim based on the HBO TV series Westworld. We thought the game looked fairly similar to Fallout Shelter.

And so did Bethesda — a little too similar.

Bethesda filed a suit in a Maryland’s U.S. District Court stating, that the Westworld game features “the same copyrighted computer code created for Fallout Shelter.”

Bethesda goes on to say that a bug featured in an early version of Fallout Shelter even appears in this mobile version of Westworld on Android.

Fallout’s publisher is seeking a jury trial and damages for copyright infringement, breach of contract and misappropriating trade secrets.
