Claude Builds Full Custom FPS Game from Single Prompt

Matt Shumer posted a playable game created entirely by Claude from one prompt, drawing millions of views and skepticism that it was fabricated. The method, termed Gauntlet Loop, sets strict performance bars the model must meet without self-grading, then splits tasks across iterations. A second observer notes the same pattern succeeds on Call of Duty-style remakes, retro ports, and other fan-fiction style projects, indicating the approach generalizes beyond games to any creative output that benefits from iterative external validation rather than internal assessment.
