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.
Build your kingdom up, or watch it burn down
Start by raising a humble castle into a bustling town, where each worker you hire breathes life into your growing kingdom. Engage in thrilling resource management, constructing a thriving economy to fund your inevitable war against a rival king. With three strategic paths through dense forests, murky swamps, and challenging factions, plan your offense and defense meticulously.
Watch your loyal soldiers fly away to heaven
But war isn't all there is! Experience a touch of life simulation as your kingdom evolves, with new town buildings appearing and diverse characters bringing your castle to life. Lead a mighty army, comprised of fearless swordsmen, sharp archers, and various other units ready to follow you into battle.
Entertain yourself with a neat riot-quelling
Engage in trade, exchanging essential resources for gold to maintain your troops' loyalty. But tread carefully, for neglect can incite rebellion, with your citizens and soldiers turning against you.
With a unique technology progression system, watch your kingdom transform from a native settlement to a formidable medieval powerhouse, offering gameplay styles appealing to enthusiasts of various eras. Guard your castle, plan your attack, and immerse yourself in a game where every decision counts, and your kingdom's fate lies squarely in your hands.
Gear up, Your Majesty, for a game of thrones, strategy, and life-simulation, all rolled into one in kingdom simulator!
