Archean

Archean is a first-person engineering sandbox where physics does the judging. You gather ore, craft parts, bolt together planes and rockets, wire their power and fluids, then program them in XenonCode. Planets are full-sized, orbits are real, and if it flies, it is because you built something that flies.

Is Archean worth it?

Archean is worth it if…

  • you like engineering where the answer is physics, not unlocks
  • you want to build vehicles and program their autopilots yourself
  • you like full-scale space with real orbits and no loading screens
  • you want solo, co-op, or modded public servers with your own rules

Screenshots

Build it standing on the wing

There is no separate editor. You assemble everything in the world, in first person, walking across your own half-finished hull.

Shape is what matters. Lift, drag, stall, and stability are computed from what you actually built, so air and water follow the same rules. Dip a wing and it becomes a hydrofoil. Damage works the same way: bend a wing and you fly lopsided.

Then you make it live. Run low- and high-voltage wiring with relays and converters, plumb fuel and fluids, seal cabins voxel by voxel until they hold pressure, and walk from the reactor room to the cockpit. You drop a docking program into the onboard computer, it misbehaves, and you debug it while parked at orbital velocity.

A solar system that runs on real math

Planets are real-sized and real distances apart, spinning on tilted axes while they orbit the sun. Dawn arrives because the ground under you rotated into sunlight, which suddenly matters a great deal to your solar farm.

Orbital mechanics run in real time with no speed limit up to 0.99c, though stopping remains your own problem. Gravity is also your problem: there is no gravity block, so you burn at 1 g or spin the station and live with the Coriolis wobble.

Start in Adventure mode with bare hands, scanning and crushing ore until every part traces back to a rock, or take Creative mode with everything unlocked. Tweak the whole star system in a config file, or build new components in Blender and script them in XenonCode.

What should you know before you start?

Do you need to know programming to play?

No, but you will pick some up. You can wire components and use the visual node editor for simple behavior, then move to XenonCode, the built-in language with syntax highlighting and multi-cursor editing, when you want autopilots, launch sequencers, or custom dashboards. The game teaches nothing by unlocks; it teaches by letting your machine fail instructively.

Can you play it solo?

Yes. Solo suits careful builders who want to mine, craft, and test in peace.

How big is the world, really?

Planets are full scale, including a young Earth with real topography and a huge Moon overhead, set at real distances with no fake boundaries or skyboxes. You will not run out of map; you may run out of fuel.
