Claude Opus 5 Powers "Claude of Duty" FPS Prototype on GitHub
Matt Shumer has released "Claude of Duty," a fully playable first-person shooter prototype built entirely by Anthropic's Claude Opus 5 model. The game, described as a "Call of Duty-style shooter," features 3D game worlds with procedural geometry, textures rendered as shaders, and physics, all generated from a single text prompt without external assets. The AI reportedly wrote approximately 55,000 lines of Three.js code, demonstrating a significant leap in AI's ability to create complex and functional game experiences directly in the browser. Shumer's project, which has quickly gained attention since its initial demo on July 25, 2026, highlights the model's capability to transform simple prompts into intricate and runnable browser-based games. The project's prompt and source code are openly available on GitHub for others to explore and build upon, illustrating the growing potential of large language models like Claude Opus 5 in rapid game prototyping and "vibe coding" interactive experiences.
