The AC-130 Spooky II is a gunship version of the basic C-130 Hercules. it is equipped with two 25mm miniguns, a 40mm cannon and a 105mm cannon.
New version with updated 105mm cannon

Controls:
AG1+Cam1 - Aiming system
AG2 - 25mm Miniguns
AG3 - 40mm Cannon
AG4 - 105mm Cannon aiming
AG5-7 - Fire 105mm Cannon
AG8 - Wing control ON/OFF

Advice for use:
Get into a position where you fly around your target (roll the plane a bit) then turn off AG8. Turn on AG1 and switch to Cam1 and then chose from one of the 3 types of guns and activate them (the 40mm gun is using flares so use the countermeasure button to fire it, the 105 mm gun only has 3 rounds each one can be fired by an AG from 5 to 7) Then activate Mouse Joystick control (right mouse button) ti aim. Aiming is a bit hard but with some practice it works just fine.

Have fun!
