The rival castle is sending wave after wave of ships to come and destroy your castle. Use all your strategy to carefully aim your cannon with your mouse. Use your high rock cannon to bring down the ships before they can destroy your kingdom. Purchase unique items to shoot from your cannon to help bring down the larger ships. As the wave of ships ends a huge ship will come, save up your big weapons and take it down and save the entire kingdom.
