AI-generated Fallout: New York taken offline after creator says Bethesda issued cease and desist

The creator behind the AI-generated Fallout: New York has pulled the game offline, saying they received a cease and desist from Bethesda parent ZeniMax Media citing trademark infringement over the fallout.nyc domain and use of copyrighted material. Built with Claude Opus 5.5 and playable in a browser, the game included quests, companions, dialogue trees, V.A.T.S. and a working Pip-Boy, and its demo video drew 3.5 million views on X. IGN has asked Microsoft for comment, as a wave of AI-generated game-merging mods this week fuels debate over the legality of such clones.
