Resource
Resources are your empire's building blocks. You use them to build ships, defenses, buildings, and droids, to research new technologies, and to move your ships around.
Types of Resources
Ore
Rocks that contain the various elements your ships and buildings are built with are plentiful on all habitable planets. By building and leveling up your Ore Mine your empire will be able to extract the precious metals needed to grow your fleet.
Crystal
A primary component in most electronics, crystal is also plentiful on most planets but is more scarce and therefore more valuable than ore. The Crystal Mine is generally the second you will build on a new planet, and will enable you to build bigger and better buildings and ships and research new technologies.
Hydrogen
Hydrogen gas is the fuel used in the nuclear fusion reactions that power most of your ships and buildings. It must be separated from water by electrolysis in the Hydrogen Synthesizer. The process is slow and energy intensive, making hydrogen one of the most valuable resources in the universe.
Power
Mines require electricity to operate, which they get from your Solar Plant. When they get insufficient electricity their production capacity is reduced, so you must always be sure to level up the plant enough to keep all of your mines properly powered.
