The defense tower is a building designed to automatically destroy nearby insects. It requires a power cell to function, with a regular cell providing enough energy for eight shots. It has a range of 40 meters, which can be visualized by pressing the range button on its interface, which resembles an orange circle with an arrow pointing outwards from the center.
