In the month of June 2018, Bethesda Softworks made allegations against Behavior Interactive and said that the co-developer of Fallout Shelter used the copyrighted code in making the Westworld mobile game for Warner Bros. Entertainment. Warner Bros. and Behavior Interactive were sued, and it was alleged that Westworld ended up being a “blatant rip-off” from Fallout Shelter. Now things seem brighter, and the lawsuit looks like it has been resolved. Bethesda claimed that the resolution was “amicable,” but the details regarding the same were not revealed. A notice was filed in US federal court and both the sides confirmed that the dispute had been resolved and they ended up paying their own costs and fee to the lawyers.
Polygon discovered this notice, and it was filed on December 12. Bethesda Softworks claimed that there was a bug in the Fallout Shelter, and it was present only in the early build of the game in Westworld. On the other hand, the owner of Westworld rights, Warner Bros. said that no code from Fallout Shelter had been used in their game. Westworld would still be available on the App Store as well as the Google Play Store for free download. Fallout Shelter was released in 2015 for iOS and Android before making its debut into PS4, Xbox One, PC, and Nintendo Switch.
At the E3 event in 2018, Bethesda revealed that Fallout Shelter was successful in reaching more than 120 million players. With respect to the size of the audience, Fallout Shelter was the most popular game from their company ever, and this meant more than the entire list of players of all Bethesda Game Studios’ titles combined.
During the launch of the game on iOS, the Fallout Shelter emerged as the top downloaded game in about 48 countries, also went on to become the top downloaded game of any kind in 25 countries and it made to the list of the top five top-grossing games on the App Store in 37 different countries. Fallout Shelter has become the third-highest grossing apps during the first week of its debut on the App Store, and it has overtaken King’s Candy Crush as well.
