Poly Kingdom: Siege is a medieval kingdom-building and strategy game where you rule as a living king in a dynamic, open world. Build your settlement, command armies, and defend your realm in a feudal society shaped by war, economy, and survival.
Start from a small fortified settlement and grow it into a thriving medieval kingdom. Assign workers, gather resources, and construct buildings that expand your influence and strengthen your economy.
