Howard Marks, founder of indie studio Xreal LLC. took to YouTube to explain why Fortress Fallout won’t be called that. The reason being that Zenimax sent the indie developer a Cease & Desist letter saying the name infringed on their trademarks relating to the Fallout series of games.
Having bought the rights to the name from Interplay a few years ago and acquired developer Bethesda, the makers of Fallout.
Marks does not intend to fight Zenimax for the right to use the name but as seen in the video, shows his disappointment that this situation occurred believing there would be no brand confusion.
