The Benelli Super 90 is a family of Italian-made semi-automatic shotguns chambered in 12 gauge.
The Super 90 is primarily used by police and military forces, although civilian versions also exist. The weapons are known for their reliable and easy-to-maintain operating mechanism. Their primary drawback is that this mechanism is semi-auto only, which makes it less reliable when firing weaker cartridges, such as less-than-lethal or beanbag rounds.
The M4 Super 90, although externally similar to the earlier M1, M2 and M3 models, incorporates a completely new internal mechanism designed to specifications provided by the United States Marine Corps. The M4 is in use with both the US military and the British Armed Forces.
In Predator 2, Mike Harrigan uses an M1 Super 90 "Entry" with a cut-down barrel, pistol grip, and laser sight whenever he needs increased firepower. He first carries it when taking down gang members at the start of the movie, and then uses it again when the City Hunter corners him inside the slaughterhouse. The weapon is later destroyed by the City Hunter, who smashes it effortlessly with its bare hands.
In Aliens: Colonial Marines, the M4 Super 90 serves as the basis for the MK221 Tactical Shotgun. The MK221 was initially supposed to be an M4 Super 90, but the name was changed and the weapon slightly modified for the release version.
In Prometheus, crew members of the USCSS Prometheus use shotguns based on the Benelli M3T Super 90 during Fifield's attack in the ship's loading bay. Jackson also uses one when facing the Last Engineer.
