Kingdom Defense Online is a castle defense game in which the player must help the lonely king defend his castle. The king can shoot the monstrous soldiers with his bow and arrows, but the player can also unlock several magical spells to rain fiery comets and giant boulders of ice onto the king’s enemies. The player must try to defeat them before they reach the castle walls.
