Solar System
Explore Solar System rules inside Interstellar Empires. Learn about garrison protection forces, resource depletion bounds, map-to-portal invasion mechanics, and asteroid belts.

Solar Systems are neutral resource nodes. Defeat their defenders to occupy them and gather basic resources.
Gathering Rules
- Access: Attack through the Galaxy Map with a fleet, or scout its symbols to discover a Portal address for ground forces.
- Resources: Solar Systems contain Food, Steel, and Energy in different proportions. Check the available resources before choosing where to gather.
- Depletion: When 10% or less of the original total resources remain, the system disappears and a replacement appears at a new location.
