PLACEMENT
You place each building on the map in its city. A building reserves the ground its largest level will cover from the start, and nothing may overlap another building or construction site. A Naval Base must sit on the coast, with water right next to the placement point. Army Bases, Airfields and Naval Bases can be built up to three times per city; every other type once. Each city works on one construction or upgrade at a time.
UPGRADES
Levels go in order, and an upgrade costs 70% of the target level's listed price. Upgrading improves a building in place — same spot, same stock. With several bases of one type, you choose which one to upgrade; the city's production slots for that type follow its highest level among them, while their parking adds up.
PARKING LIMITS PRODUCTION
| BUILDING | SPOTS AT L1 / L2 / L3 |
|---|---|
| AIRFIELD | Fighter stands 6 / 10 / 15 · heavy stands 1 / 2 / 4 · helipads 4 / 7 / 10 · drone shelters 4 / 6 / 8 |
| ARMY BASE | Vehicle bays 8 / 14 / 20 · barracks 6 / 10 / 14 |
| NAVAL BASE | Small berths 4 / 6 / 8 · large berths – / 2 / 4 · submarine pens – / 2 / 4 |
Each unit class needs one spot of its kind. A city can't start another unit if every spot of that kind is taken — counting aircraft based there (even while flying), ground units and ships standing within 1 km of its bases, and units already queued. Parking never stops a unit from moving or landing; it only limits production.
REPAIR & DEMOLITION
Repair costs half the building's original cost, scaled by how damaged it is, and restores it to full HP once paid. Demolishing refunds 30% of original cost, scaled by current health, and cancels any queued upgrade on it. A city that's been captured but not yet annexed can't build, upgrade or produce at all — see Annexation.
