About the Game
Castle Siege is a multiplayer 1v1 tower defense and offense game, set in a stylized medieval world.
One player attacks, and the other defends. The attacker can buy units and send them out to destroy the castle. The defender can place turrets along the path to stop the units.
Upgrade your units or turrets to give them special traits like lifesteal, health regeneration or extra damage.
Buy magic spell cards to inflict damage on your opponent, or to buff your own troops.
