Players take opposite sides in a siege; one has to defend the stronghold, the other has to break into the castle as soon as possible. The defender has a small amount of soldiers manning the walls, while the invader has an infinite legion of them! A desperate fight takes place every turn. The invaders build war machines, equip their soldiers, train them and use black magic rituals to achieve victory. Meanwhile, defenders repair walls, build cannons, train soldiers and do everything they can to hold the castle as long as possible—the longer they can, the more victory points they gain to determine the winner once the Stronghold walls are finally breached!
