Linus Ekenstam Builds a Dune Buggy Racing Game End-to-End with AI Agent Astra
Linus Ekenstam shared the full process on September 13 of how he used the AI agent Astra to develop a dune open-world off-road racing game: the project started as a simple task for Astra to model the Amble One car in Blender based on images from the Amble website, and gradually evolved into a complete game prototype with driving physics and an open world.
Confirmed
- Based on a few reference images, Astra completed the entire Amble One car model directly in Blender, automatically generating material shaders, suspension spring animations, a steering wheel and other details; Ekenstam joked that the result resembled "a fancy golf cart with light off-road capability"
- The game already features independent four-wheel suspension control, power distribution, sand traction (drifting), sand particle effects, radio channels and sound effects
- Given a task and a Google Maps screenshot, Astra generated a 15x14 km 3D terrain of Marbella, Spain in just over an hour, containing 4,393 houses, 2,492 backyard pools, roughly 20,000 buildings and about 450 km of drivable roads
- He stressed that the point of this exploration was not to make a game people would play, but to test "what Astra and I can do together": they could chat, playtest and adjust at any time, with extremely fast iteration
Why it matters
- This case shows that a single person with an AI agent can complete the entire game development chain—from modeling and physics to terrain generation, sound effects and radio—providing a concrete example of a "one person + agent" development workflow
