In Destiny, the Hunter Guardian class has the Golden Gun super.
Golden Gun belongs to the Hunter's Solar-based Gunslinger subclass. When activated, it creates a flaming magnum capable of delivering exceptionally powerful shots; in the original Destiny, its base magazine held three rounds. The ability rewards accurate aim and is especially effective against strong enemies or vulnerable bosses.
Hunters are designed around mobility, agility, scouting, and precision. Their other original subclasses reinforce that identity: Bladedancer uses the Arc Blade for close combat, while Nightstalker, added in The Taken King, uses the Void-based Shadowshot bow to tether enemies.
The main source of confusion is that every Guardian class has powerful “super” abilities, but their signature effects differ. Titans use abilities such as Fist of Havoc or Ward of Dawn, while Warlocks use Nova Bomb, Radiance, or Stormtrance. Golden Gun is specifically associated with the Hunter's Gunslinger path.
