The Double Twin-Linked Anti-Air turret launches target seeking missiles that damages any flying enemies caught in the explosion. It is very effective against closely packed flying enemies.

Placement StrategiesEdit

  • Due to the low fire rate and high range of AA towers, a few powerful towers are better than many weak ones.
  • The AA tower's homing missile will (presently) not lock onto a new target if it's original target dies mid-flight. Consequently, it is advised to place AA towers far apart so they will not lock onto the same target.
  • Having multiple lines of AA towers will maximize their efficiency. Two in the front, two in the middle, and two in the back would allow for the first set to weaken the target, the second set to kill it, with the 3rd there to ensure the death of any stragglers.
  • Air units tend to go along the outskirts of your maze, instead of the middle. As such, placing an AA tower against either wall is more effective than two AA towers a block apart in the middle.
