The Cannon Tower is a basic defensive building found in almost all missions.
The Cannon Tower is a simple turret that fires single cannon shots. The shells are easily dodged and the tower itself has very little health, making the Cannon Tower very easy to destroy.
Its elite variant is the Barrage Tower.
