You start beside a Cybertruck in an open desert and drive toward a walled city called Halcyon, drifting through sand that keeps your tire tracks. Press R and the truck unfolds into a robot that walks, jumps and fights, and Tab switches between six vehicles. It uses real car brands such as the Tesla Cybertruck and a Ferrari F1 car. The creator says it's still a work in progress and has published the source. Allow time for the first load and play on a computer with a keyboard and mouse.
How the creator made it
The creator built the game with Claude Opus 5.5 and GPT-6 Astra in Three.js on WebGPU. They say Opus built most of the Roadster and Astra solved a few structural problems Opus had struggled with. They also used Opus for the Roadster's transformation animation.
