With the development of AI technologies, “vibecoders” have emerged. Such people do not write programs themselves, but create program code using requests to artificial intelligence. The task is set in ordinary human language, and as a result, AI produces ready-made code.
Recently, various ports and modifications have actively appeared online, which are created with the help of AI or entirely generated. Some enthusiasts are already applying AI capabilities in game development. For example, a post by developer Chris First recently went viral. With the help of Claude Opus 5.5, he managed to create a 3D game Fallout: New York with a VATS system, a working Pip-Boy computer, and other recognizable elements of the Bethesda Game Studios franchise. Soon, lawyers noticed the project and quickly shut it down.
Another company, also owned by Xbox, also began to act. Activision lawyers shut down developer Maurice Heumann's project. He used generative AI to decompile Call of Duty: Modern Warfare 2 on PC, i.e., he converted machine code into ordinary code that a human can read. According to him, seventeen AI agents worked on this simultaneously and they worked faster than would be possible with manual labor.
Maurice Heumann claims that Call of Duty: Modern Warfare 2 was in a playable state and most bugs had been fixed. But it did not come to a full release: Activision removed the video and blocked access to the site where the code was hosted.
In one of his subsequent posts, the developer admitted that one of the AI agents completely wiped his system. But he was working on a virtual machine, so no critical data was lost.
The shutdown of Fallout: New York and the AI decompiler for Call of Duty: Modern Warfare 2 shows that some copyright holders are not going to quietly allow such projects created with AI technologies to exist.
