Finally we are ready to attack! Step by step, we will free our lands from the invasion. The control center is our main stronghold in the battle. It allows you to build towers and other objects. Don't let the zombies to destroy it. Our radars have detected a crowd of zombies approaching. It's time to get on the defensive! Build a tower in a suitable place. Now let's build a rocket tower. Each destroyed enemy gives 1 or more energy points. We need energy to build towers. Later you can increase the energy bank capacity. We need a mortar, let's build it near the bridge. The tower consists of a tower head and a base. We put the mortar on an improved base and this will increase its range. And finally fry them with high voltage.
