An AI built a browser shooter from a single prompt with zero art files

A complete browser-based first-person shooter was built in Three.js from a single prompt — and it contains zero image or audio files.

Matt Shumer released Claude-of-Duty, a GitHub project that reached 2,398 stars this week. A fleet of AI agents generated all 55,000 lines of code across 11 subsystems. Every 3D mesh, texture, gun animation, and sound effect is generated procedurally in the browser at runtime using WebGL2.

Why it matters: It proves AI coding agents can architect and build complex, multi-system software projects without human-written boilerplate. But it also highlights current limits: 11 independent critics scored the game 5 out of 10 against real Call of Duty, citing blocky hands, mannequin-like enemies, and procedural noise on close-up surfaces.

To try it locally, run npm install and npm run dev. Click the browser canvas to lock your cursor and use standard WASD and mouse controls.

It won't replace your console games today, but watching AI generate a full game engine from raw code is a clear preview of where game dev is headed.
