Activision And Bethesda Crackdown On GenAI MW2 And Fallout Projects
There’s currently a free-for-all when it comes to vibe coding video game slop, including knock-offs and decompilations of existing games, and not every company is okay with it. Activision and Betheda, both owned by Microsoft, recently took action against two different projects.
The first was called Fallout: New York. A clip shared by ChrisFirst on X showed an attempt to recreate the open world shooter in the big apple in a form that would be playable in people’s browsers. It was coded with Claude Opus 5.5 and certainly looked like Fallout out a glance.
“Quests. Dialogue trees. V.A.T.S. A working Pip-Boy. Zero texture files. Zero sound files,” ChrisFirst wrote. “Every building, weapon, face and sound is generated by code.”

The project didn’t last long, however. The initial post, shared on September 28, racked up over 3.5 million views. But just days later, on October 1, ChrisFirst confirmed he was abandoning the project after receiving an alleged cease and desist from Bethesda for infringing on its IP. “Hey, Bethesda Studios how about you make a Fallout game instead so I don’t have to?” he wrote alongside a screencap of the legal threat. “Sorry to everyone who enjoyed the game! But the suits got involved and the fun is over.”

Am AI vibe coded Call of Duty project also caught the attention of gaming lawyers this week. Maurice Heumann shared on X on September 30 that he was using genAI to decompile the source code for the original Modern Warfare 2 on PC. “With currently 17 agents working in parallel, we’re making progress at an incredible pace,” he wrote. “The game is fully playable now and almost all visible bugs are gone. Only a few are left. I even managed to get my first nuke.”
