Siegius is a storyline driven real-time strategy game set during the Gallic Wars. You play as the general of the Roman or Gallic troops, placing soldiers on the battlefield to counter and overpower your enemy. You have several units at your disposal, including swordsmen, archers, defenders, healers and miners. However, not all units will attack your enemies. Miners supply you with gold and can only be placed on mining areas. Healers are weak units who don't fight, but have the ability to heal nearby soldiers. In addition to deploying soldiers, you can cast spells once you have unlocked them. You have the choice to upgrade your soldiers and spells prior to each battle.
