Cannon Tower Defense is a combination of strategy and shooting games where different types of enemies attack a castle tower out in a lonely desert. There is a cannon on the top of the tower to defend it from these enemy attack. Consecutive shooting to these enemies is the key defense in these shooting games. Use your power-ups carefully. Like any other shooting games, you might end up with a lack of ammo if you don't use power-ups properly.
Cannon Tower Defense is one of the easiest control tower defense games. It's unique for this simple control mechanism. Player will only have to put the power by tapping left to right on the screen. The speed of the cannon ball depends on the horizontal touch position. Cannon speed is proportional to touch distance horizontally from left edge of the device screen.
