Based upon the design of Dr. Richard Gatling's Gatling gun, the Gatling laser uses multiple rotating barrels to fire a heavy and impressive stream of light radiation laser beams without overheating quickly.
H&K L30 Gatling laser
An H&K L30 Gatling laser (also referred to as the Sunbeam Gatling laser). Designed specifically for military use, these were in the prototype stage at the beginning of the Great War. Multiple barrels allowed longer firing before overheating. These models are powered by microfusion cells.
UB-FRIED 3000 Gatling laser
In contrast with the L30 Gatling laser, this model is not only fully automatic and has a much larger ammo capacity, requiring a back-mounted battery pack, but was also mass produced for military use. While they entered service shortly before the war, they quickly became an important part of the arsenal, both of pre-War and post-War factions.

Unnamed Gatling laser
Similar to its predecessor, this model is fully automatic, providing that charging barrels have not been installed. However, it utilizes a fusion core as ammunition rather than a battery pack, and features four rotating AER9 barrels firing laser pulses through two lenses (as opposed to merely firing in a rotating order).

(Robert House's dialogue)
- Yes Man: "Our left arm contains an X-25 Gatling laser, quite deadly against soft targets at medium range. That looks like fun!"
