A 3D moon rover survey game in plain WebGL2
Claude Code (Opus 5) built a browser moon rover game whose physics, terrain, textures and sound are all generated by code, refined over many rounds of fixes.

The full story
This is a 3D moon rover survey game made with Claude Code using Opus 5: about 6,300 lines of JavaScript, a copy of three.js, no game engine and no build step. The ground keeps every rut the wheels cut, because the wheels and the shader read the same height field. There is a five-mission campaign, a free survey mode, and every texture, rock, star and sound is generated by code at load, so the download is about 380 KB.
It began as a single prompt that produced a playable build, but the maker says the current version came from rounds of fixes: inverted steering, wheels floating off the chassis, a HUD covering half a phone screen, and a settings panel that had been collapsing to a 2px strip since the first commit.
