This papercraft is a N7 Hurricane, a submachine gun in the game Mass Effect 3, the paper model was created by PepMaster. The N7 Hurricane is included in the N7 Collector's Edition Pack as a bonus item for players who order the Collector's or Digital Deluxe Edition of Mass Effect 3.
While some militaries pass on the Hurricane because of its lower accuracy, the Alliance feels the gun's rapid firing rate offers excellent suppressive fire. A disciplined marksman can use the fully automatic submachine gun to chew through targets with alarming speed. Alliance officers were so pleased with field results that the Hurricane is now many squadrons' standard-issue SMG.
