Defensive buildings add to your sector defense bonus. There are two types of defensive buildings:
- Perimeter defenses: walls, gun turrets and sensors.
- Improvements: Particle Projector cannon, electric bar, flux generator, BR-17 field mass driver.
Active turrets - gun turrets not only add to your defense bonus, but also fight for your sector like a regular unit. Once purchased, gun turrets cannot be completely destroyed - your friends can repair them in seconds by tapping on them, or they can be repaired by the owner in 2 hours.
