Microsoft and Epic Send AI Takedowns While Building With the Same AI

Microsoft and Epic Games are issuing copyright takedowns against AI-assisted game recreations while both companies build their own products with the same AI tooling. Kotaku reported the criticism on October 26, 2026.

Hundreds of DMCA notices have gone out from companies responding to a wave of AI-assisted game recreations, including browser-based ports and recompilations for hardware the games were not originally designed for. The wave is widely attributed to Anthropic's Claude Opus 5.5, released September 22, 2026, whose reverse-engineering capabilities enabled rapid decompilations and recompilations.

The notices do not come from Microsoft and Epic alone.

What is documented is that both companies are betting on the same capabilities. Epic pushed developers on an unannounced Disney shooter featuring Marvel and Star Wars characters into an "AI-first" production model using Claude models, with art to be "generated with full AI workflows," according to a Bloomberg report covered by Kotaku on October 12, 2026. On October 14, 2026, Epic released a rebuilt Epic Games Launcher in Preview, describing it as "vibe coded."

Around October 21, 2026, users reported that Claude Opus 5.5's reverse-engineering ability may have been quietly nerfed through safety guardrails.

The tension is not hypocrisy alone. The same AI capabilities that let publishers cut development costs also let outsiders rebuild and redistribute their games without permission. If AI makes intellectual property reproduction trivial, copyright takedowns become the primary defense — and smaller independent studios, with fewer legal resources, are the most exposed when their work is reproduced without permission.

Whether "AI-first" development and aggressive IP enforcement can coexist as a public stance is now an open test for both companies.
