Linus Ekenstam Builds Dune Buggy Open-World Game Solo With AI Agent Astra
On September 13, Linus Ekenstam shared his full journey building a dune open-world offroad racing game with AI agent Astra. What started as modeling the Amble One buggy in Blender from reference images evolved into a complete prototype with driving physics and an open world; he framed the effort as exploring "what Astra and I can do together" rather than shipping a playable game.
Confirmed
- Astra modeled the entire Amble One vehicle in Blender from a few reference images, automatically generating material shaders, suspension spring animations and steering details; Ekenstam joked it resembled "a luxury golf cart with light offroad capability"
- The game features independently controlled four-wheel suspension, power distribution, sand traction (drifting), sand particle effects, radio channels and sound
- Given a task and a Google Maps screenshot, Astra generated a 15x14 km Marbella, Spain terrain in about an hour, with 4,393 houses, 2,492 backyard pools, roughly 20,000 buildings and about 450 km of drivable roads
- He iterated rapidly by conversing with, playtesting and adjusting Astra in real time
Why it matters
- The case shows a single person plus an AI agent can cover the full game development chain—modeling, physics, terrain generation, audio and radio—offering a concrete sample of a one-person-with-agent workflow
