Crystals is a primary resource mined on all the asteroids of the Oort Cloud.

The player can use it to produce ammunition, construct buildings and also as a fuel for their asteroids to move them within the Oort Cloud.

To get crystals, the player can:

  • build a Mine
  • complete a quest
  • find them near the asteroid belt during the battle
  • commit a robbery

Figures in the top panel show the total amount of all crystals available on the asteroid. When warehouses are full, the figure turns red and crystals start disintegrating.
