Machine Fist

 is a gun that alternates between firing a gatling gun, and a single shot exploding rocket punch that is guided by the player's cursor upon reloading.

Trivia

 * This gun is a reference to a weapon of the same name from Final Fantasy VII along with its user, Barret, and the group of eco-guerilla fighters he founded: "Avalanche".
 * The flavor text is a reference to Barret's Subplot with his former friend Dyne who also had a Machine Fist installed.
 * The synergy is a reference to an insult Barret once directed at the city of Midgar, calling it "that &^#$# 'pizza'", referring to the way that the upper level of the city was built on an enormous circular metal plate suspended above the lower level of the city.
