In the game Castle Defense, we will go to a far fairy world where there are two kingdoms. In one live people, in the other there are different monsters. Between these two countries there is a constant war and today we will take part in this conflict. You have to command the defense of the castle on which the army of monsters attacked. At the top of the tower will be installed a gun that shoots special cores. Your task is to aim it at the monsters and open fire. For the points you received from killing monsters, you will be able to purchase new kernels and even magic spells to help you destroy the enemy more effectively.
