The FWC made a thing that made guardians have visions of the future and go mad, and one hunter that was full of madness made a pulse rifle and out a bayonet on it, but this was before the gun had the smart meta where it could give you health for killing, it was used in the crucible in the faction wars, but when the faction wars ended, the maker and the gun was banished, the banished hunter lurked around old Russia when he found a patrol, he notes that one of them had the suros regime, he killed them all and used the suros regimes smart meta to give health to the person wielding it once they killed something, the hunter still exist and is on earth, so if you see a guardian with a knife on there gun, regard vanguard policy and run!
