Plasma Artillery Cannon

A Plasma Artillery Cannon is a weapon installed on Elite Pirates in Metroid Prime. It is connected to the Elite Pirate's energy siphon system to fuel their cannons with absorbed shots from Samus. The cannon can be scanned seperately, similar to an Ingsmasher Missile Launcher.
