How to grow production
- Raise the mine level — each level increases hourly output.
- Keep production at 100% in the planet settings.
- Avoid an energy shortage — when energy runs short, metal, crystal and deuterium output drops.
- Build the Production Fund — it accumulates a share of your output.
- Upgrade your storages — otherwise surplus is lost on overflow.
Crystal also comes from Expeditions and can be exchanged at the Trader.
