An army of invaders is moving towards your castle. You in the Castle Defense game will have to protect your castle and destroy opponents. In front of you on the screen you will see the area in which your castle will be located. You will have to consider it very carefully. Using a special control panel with icons, you will have to place your soldiers of various classes in a given area. As soon as the enemy approaches them, the battle will begin. Your soldiers using their weapons will destroy the enemy and you will be given points for this. On them you can recruit new soldiers to your squad or buy new weapons for your squad.
