Built to grow.

Build four Markets, then combine them at Citadel 7. Once combined, build Supermarkets directly at Citadels 11, 15 and 19. Four Supermarkets become one Trade Empire. Offers and purchase limits are shared per player, not per building.

Progression
Market → Supermarket

One Trade Empire per colony. Adds 10% to all gathered resources. Unlocks 24-hour shields at 300,000 Gold, limited to two per player per day. Special offers can include up to two Rift Beacons daily, when available.

Unlocks building levels, research, missions and territory expansion. Citadel 21–30 adds power and combined-building requirements, sharply higher costs and longer timers. There is one Citadel per colony.

Combination multiplies the housing represented by the four input buildings and applies the combination bonus. Wounded, deployed and reserved training troops all count towards housing.
