An independent developer says GPT-6 Astra helped recreate a browser-running version of Call of Duty 2 in about 10 hours, turning a 2005 PC shooter into a fresh test case for agentic game development. The developer said the build was not being released because the original game is copyrighted, leaving the demonstration as a claim to be scrutinized rather than a downloadable product.
