The bell has rung and the invasion started, so prepare the island defense in this strategy game. Upgrade towers after placing them to stop the invaders. Pirates, barbarians or simply strangers, many names can be used against the enemies, but only the arrows and cannon balls make effect. Death waits for them before the gates. Defend the farmers and peasants who took protection behind the walls, using the Mouse to build towers and expel the men who came in ships out of the island. Click on the buildings to give them more critical chance and earn bonus for calling the waves sooner.
