Resource Asteroids are the source of metal and crystal. To harvest Resource Asteroids at colonizable planets, you must colonize the planet, then build Metal Extractors or Crystal Extractors on them. Resource Asteroids in uncolonizable gravity wells (such as in Asteroid Belts ) already have extractors built on them, and can be captured by TEC and Advent colony ships or Vasari scouts. You can increase the amount of resources you earn from asteroids by building Orbital Refineries.


  • Each extractor at your planets earns you 0.4 resources/sec. This is affected by allegiance.
  • Each extractor you own at an uncolonizable planet earns you 0.53 resources/sec. This is NOT affected by allegiance.
  • Each refinery earns you additional income, see the Orbital Refinery page for details.
