A free browser tribute to GTA: Vice City built with Claude, with every building, car and radio station generated by code and each change playtested headlessly.

The full story
Neon Mayhem is a fan tribute to GTA: Vice City, built with Claude and free in any browser. There's a neon city island and a hill-road island, car theft, a five-star wanted system up to police helicopters, taxi and paramedic jobs, planes, parachutes, day and night and synth radio.
There are no asset files: every building, car, texture, sign, siren and radio station is generated by code at runtime, in about 14,000 lines of JavaScript plus Three.js. The repo's rule is that nothing ships without headless checks, so Claude built a scriptable test API and playtests every change in a headless browser, enforced by CI.
