Power -10 Energy/cycle
Cost 80 Minerals

Tips

Chain after extractors for efficient processing. Refined materials are required for advanced buildings.

Energy Cell Factory

Manufactures energy cells for advanced buildings and research.

Input -5 Minerals, -3 Power/cycle
Output +4 Energy Cells/cycle
Cost 100 Minerals, 20 Refined Materials

Tips

Critical for mid-game expansion. Energy cells are used in nearly all advanced buildings. Build multiple for large colonies.

Infrastructure Buildings

Solar Array

Basic power generation using solar panels. Reliable but limited output.

Output +20 Energy/cycle
Cost 25 Minerals

Tips

Your first power building. Build multiple for adequate power. Upgrade to Fusion Reactor for higher output.

Fusion Reactor

Advanced power generation with high output but requires fuel.

Output +100 Energy/cycle
Fuel -2 Energy Cells/cycle
Cost 200 Minerals, 50 Energy Cells

Tips

Most efficient mid-game power solution. Requires Energy Cells as fuel. Build near industrial zones.

Warehouse

Storage facility that increases resource storage capacity.

Storage +500 All Resources
Cost 60 Minerals

Tips

Build before increasing production. Specialized warehouses exist for specific resources with higher capacity.

Ecology Buildings

Ecodome

Restores and maintains local ecosystem health. Essential for Kewa's wellbeing.

Ecology +5 Health/cycle
Power -4 Energy/cycle
Cost 50 Minerals, 10 Energy Cells

Tips

Build in damaged areas or near extraction zones. Multiple Ecodomes stack healing. Place strategically before expanding.

Biodome

Creates a complete self-sustaining ecosystem with biodiversity bonus.

Ecology +15 Health/cycle
Bonus +10% Resource Quality nearby
Power -8 Energy/cycle
Cost 150 Minerals, 30 Energy Cells

Tips

High-impact building. Place near production zones for quality bonuses. Essential for late-game optimization.
