Archean

Archean is a deeply immersive Engineering Sandbox.

Begin your journey on primordial Earth, over 3 billion years ago, in the Archean eon—a time when the world was raw, untamed, and full of potential.

Craft, experiment, and engineer your own creations—solo or with friends—in a sandbox that doesn't hold your hand. Every system is simulated, every challenge earned.

And when you're ready to go beyond? This is also a full-scale space sim, with realistic physics and orbital mechanics.
