Defense zone provides a stunning detail of levels, in-depth gameplay, finely tuned balance of all levels and turrets. During the game you will hold your defense with your turrets against the massive hordes of enemies.
With every level you will have the use of new weapons at your command. It is up to you, Commander, how to spend the resources: to restore and upgrade your veteran units, or to purchase some new ones. Different types of weaponry and landscape provide you with a variety of choices of defense tactics.
Choosing the right weapons and the correct placement is key to any successful defense. The weapons have different firepower, rate of fire, firing range, blast radius, and price.
