The tetryon Gatling gun was a Klingon automatic "Gatling"-style energy weapon. It was picked up by Lieutenant Alexander Munro aboard the Klingon K7 Starbase. As with all Gatling guns, the weapon fires from multiple fast-recharge chambers and requires large amounts of energy in continuous fire. The weapon can also fire a type of energy grenade, a tetryon pulse that bounces off surfaces to reach a target, or will eventually dissipate.

The weapon was utilized by the Hazard Team after Munro found it in 2380. (Game: Star Trek: Elite Force II)
