Structure | — | Base building |
| Building | Cost | Requires | Purpose |
|---|---|---|---|
power_plant |
300 | CY | Powers base |
barracks |
500 | Power | Infantry production |
refinery |
2000 | Power | Ore → Credits + spawns harvester |
war_factory |
2000 | Barracks | Vehicle production |
Harvesters collect ore from the map → deliver to Refinery → credits added to your balance → spend credits on production and construction.
