Void Core Cannon

 is a gun that fires bursts of four large energy balls, which home in on enemies and explode upon impact.

Trivia

 * This gun uses the same sprite as the unused Void Core Rocket Launcher.
 * This gun is a reference to the Plasma Projector carried by the Assault T-Synth from Void 1.1.
 * Both Glass Cannon and Void Core Cannon have "Cannon" in their name, yet do not trigger the synergy.
