Zero-G is a browser-based space MMO where the Solar System is real. The planets, moons and terrain are built from actual NASA maps at 1:1 scale. Your ship doesn't move on rails — it obeys Newtonian physics, so every burn, orbit and landing is something you actually pilot.

What you can do right now (Public Alpha):

  • ๐Ÿš€ Launch from the Grottaglie Spaceport and fly out into the system
  • ๐Ÿช Explore real planets and moons rebuilt from NASA terrain data
  • โ›๏ธ Mine asteroids for resources
  • ๐Ÿ’ฐ Trade at the player-driven Auction House — a real economy, run by players
  • ๐Ÿ›ฐ๏ธ Develop your pilot across missions, races and expeditions
  • ๐ŸŒ Colonize and help shape a persistent, shared universe

Grab a seat in the first wave. Zero-G is in active Public Alpha: it's free, it runs in your browser, and new systems ship regularly (asteroid mining and the Auction House economy are the two most recent). You're playing an early, evolving build — that's the point. Come help us find what's fun, break things, and watch the universe grow patch by patch.

โ–ถ Hit "Run game" above to fly now. No download, no account wall — just play.

Building something this big is a labor of love from a small, dedicated team. If you're a developer, artist, or simulation nerd who wants to help shape a living universe, we'd genuinely love to hear from you — reach us in the Community tab or our Discord. But first: go fly.
