Claude of Duty is a first person shooter game that runs entirely in a web browser, built with the Three.js graphics library. It was written almost entirely by a team of AI coding agents working together, and it is unusual in that it has no art files at all. Every texture, character, sound, and animation is generated from code the moment the game loads, rather than loaded from image or audio files. The game includes many of the systems a real shooter needs: lighting and shadows, procedurally generated surfaces like brick and metal, a small outdoor market street you can walk through and enter buildings in, physics for movement and bullets, weapons with recoil and reloading, enemy soldiers that can see and take cover, sound generated entirely in code, and an on screen heads up display with a crosshair, minimap, and kill feed. You run it by installing dependencies with npm and starting a local development server, then move with the keyboard and aim with the mouse like a typical shooter. What makes this project interesting is not just the game but the testing tools built alongside it. The README documents a set of scripts for taking screenshots of the game in a consistent, repeatable way, comparing images pixel by pixel to catch unintended visual changes, and profiling how the game performs frame by frame to find slowdowns. These tools uncovered real problems, including stalls caused by graphics code compiling mid game and screenshots that were not actually reproducible until the tooling was fixed.
