Citadel: Fortress Siege
About Citadel: Fortress Siege: Medieval 3D Real-Time Strategy
Citadel: Fortress Siege is a medieval 3D real-time strategy inspired by classic castle simulators. The game drops you onto an expansive map with a single lonely keep and challenges you to design an impenetrable stronghold from the ground up. Six vital resources — timber, stone, gold, food, water, and citizens — drive every decision, from the first house you place to the final assault on a rival citadel.
A tall stone tower with a red-tiled roof and four small square windows stands at the heart of the settlement in several scenes. Blue and red lines trace jagged paths across the green grassy terrain in multiple views of the map.
How to Play Citadel: Fortress Siege: Connect, Defend, and Conquer
Everything in Citadel: Fortress Siege revolves around your keep. Production buildings only function when linked to it by roads, and those roads also boost unit movement speed by 35%. Build houses, farms, and towers on the grid, then lay paved roads through the Economy tab — each road segment costs 2 gold. The objective is to connect your workshops to the keep, defend the donjon, and conquer rival citadels.
On the military side, recruit swordsmen, archers, pikemen, knights, and catapults. True 3D ballistics give archers stationed on high battlements a commanding advantage over attackers below. Flaming arrows can ignite pitch trenches, engulfing enemy assault columns in fire. Forge treaties through the embassy, trade resources on the market, or take rivals down by force.
