Designing the defense system in Age of Pirates is one of the trickiest things that players have to contend with. Players use all kinds of strategies in order to design the perfect defense system to keep out their enemies. One of the best strategies for designing the defense system is to make sure that you are not creating it on the seashore. The defense system must be kept away from the sea-shore to avoid direct attacks from the enemy ships. It is best to create high-rise walls for your defense system to avoid the attack of archers from the ground or from ships.
