There are 6 ways of gaining resources:
- Basic Income. Every planet has a basic income of a small amount of metal and crystal but not deuterium.
- Mining. Building and adding levels to Metal Mines, Crystal Mines, and Deuterium Synthesizers increase the hourly production of resources.
- Harvesting debris fields with a recycler. Available debris fields can be seen from the Galaxy View.
- Attacking planets or moons.
- Trading with other people in the game for a profit.
- Expeditions. This is done by sending a fleet to planet position 16. Expeditions can reward you with resources, ships or dark matter, or you can lose part of your fleet or all, or nothing happens.
