Crystal

Crystal is one of the 3 main resources in the game. A constant supply of crystal is required for research and energy development, being required in the most quantities for researches. It is used to create electronic circuits and form alloys.

Crystal can be produced in mines, captured in a raid, and harvested from a Debris Field. It is stored on your planet and can be spent on items such as ships, defense, technology and buildings.

When making ships however, metal is more important than crystal, and a good metal output is recommended if one is focusing on making ships. That said, a crystal shortage is one of the most common causes of production cessation.
