Concept of Anti Air Gun by Jim Martin
The New Mecca air defense cannons are seen firing all over the sky, when the Necromonger Empire begin invading Helion Prime. The weapons seem to have little effect against the Necromonger ships as a Conquest Icon falls, the munitions seem to just hit and fade.
Power[]
The weapons seem to run off of solar energy, because after the conquest marker hits, and causes the power to go out, the weapons stop firing.
Ammo Types[]
The guns seem to fire a quick hail of standard bullets, then shoot out a barrage of rockets.
