Air Sweeper

2x2, pháo bắn đạn laser, chống máy bay

This anti-air tower is deadly against flying enemies, but can't target foes on the ground. Place it wisely to cover as much airspace as possible

Summary:

• The Air Defense is a powerful turret, unlocked at Technology Center level 4, that exclusively targets aerial foes with very high DPS, good reach and decent hitpoints

• Air Sweeper can only target and shoot one air troop at a time

• It cannot harm ground-based units, or interfere with them in any way other than potentially distracting them from attacking a more valuable target
