Data Status

  • Unlock levels: Early Access 0.8.5, checked 2026-10-06. Other sections retain their earlier review date.

How the Tech Tree Works

The tech tree is organized by tiers. Each tier unlocks new blueprints and systems. You earn skill points as you progress, and spending those points locks in your path.

Because the game is in Early Access, unlock costs and tier contents can move between patches. Always verify your current build menu before committing points.
