Zorgun

 is a gun that fires homing bullets. The last shot of each magazine fires an RPG rocket, a Grenade Launcher grenade, or a Bullet Bore bore. Holding down the fire button will not automatically fire the last round, the button must be let go and pressed again.

Trivia

 * This gun as well as its description is a reference to the villain Zorg and the ZF1 weapons he sells in the movie The Fifth Element; the tagline "Don't push the red button" is in reference to the ZF1's red self destruct button.
 * The synergy may be a reference to a song from indie musician Lemon Demon bearing the same name.
