These guard towers are equipped with machine guns and are fairly effective at keeping the competition out.
A fully powered Surveillance Center is required for the targeting systems to function so that towers will fire automatically as enemies come into range. You can also direct their fire by tapping on the tower and then tapping on the enemy you wish to fire upon.
Note that these towers take a great deal of power to remain operational. As you create towers, be sure to keep an eye on your power meter. A flashing lightening bolt symbol on your tower indicates that it is under powered and will not fire at the enemy.
