Helipad

Overview
It is similar to the Garage but it exclusively holds helicopters and is located behind the Air Control Tower. You can only unlock it when you fully bought the garage. It can be unlocked after purchasing Weapon's Lab.

Helicopters can be damaged by explosions (boomer zombie), projectiles by rocks thrown by Tough Zombies and spit from Spitter Zombies or when Void Zombies teleports to the pilot, this is the only way flying helicopters can be damaged, but they can be damaged when the propeller hits something. They can be repaired from the pad or by using a Vehicle Repair Tool.
