The Siege Engines Mini Expansion showcases six formidable siege constructs. Similar to Mercenaries, these units can be recruited by any player without any prerequisites. They possess distinctive abilities that are specifically tailored to provide you with a strategic advantage in various types of battles. For example, the Ballistae excel in ranged attacks and prove to be formidable against Heroes and Air Vessels. On the other hand, the Catapults also possess ranged attack capabilities and are specifically designed to demolish towers and sea vessels. Lastly, the Siege Towers are solely dedicated to obliterating Capital Cities, making them an unstoppable force on the battlefield.
