A very simple mod. In this mod you build Jumpjet VehicleTypes (Siege Chopper, Floating Disk, Nighthawk, and more!) from airfield. Jumpjet Vehicles (Helicopters) now share the same building queue with pad aircrafts. Roofs of war factories would never open! The engine limitations have been lifted.
These pilotless aircrafts can drop itself to the ground and deploy into an altar. The alter has relatively high hit points and deals high damage but the aircraft mode is vulnerable. The best way to counter is to build enough AA defense to shoot them down before they can deploy.
