mshumer/Claude-of-Duty ? reverse-engineered prompt

Build me a browser first person shooter that feels like a modern military shooter, but it runs entirely in Three.js with WebGL2.

I want it to launch in the browser, let me click to lock the cursor, and support normal FPS controls like WASD movement, mouse aiming, shooting, aiming down sights, reload, sprint, crouch, jump, leaning, and releasing the cursor with Esc. Please make everything generated in code at load time, so no image files, sound files, models, or other art assets are needed.

The game should have a believable 3D world with buildings, props, enemies, weapon handling, basic combat, and a full HUD with things like a crosshair, hit markers, minimap, compass, and killfeed. It should also have solid lighting, fog, shadows, particles, and procedural audio so it feels polished instead of placeholder.

If you need current docs or details for Three.js, look them up online. I’d also like the project set up so I can run it locally with a simple dev command and play it right away.
