AI Agents Build AAA FPS Game in ThreeJS

Investor Matt Shumer posted on X about a prompting approach called the Gauntlet Loop. It directs an AI to break goals into parts, assign specialist builder and ruthless blind critic sub-agents to each, and iterate until the output exceeds real-world equivalents such as recent Call of Duty titles. Variants using Opus 5 agents have been applied to generate a first-person shooter in ThreeJS. Shumer states the sub-agent critic method is the core value and plans to demonstrate its use beyond games for nearly any project.
