Forgotten flak cannon

The flak cannon is a Forgotten anti-aircraft defense in.

Description
Immobile, towering, wall-linking. Deadly against anything that flies. Cannot attack ground units, especially deadly anti-structure vehicles.

Game building
The flak cannon spawns in 20+ camps although, rarely in level > 18 camps.

It should be noted that the flak cannon counts as a structure and anti-structure ground vehicles or infantry can demolish these quickly. Firehawks and Vertigoes can eliminate flak cannons as well, as long as the flak does not get them first.
