Gatling Laser (Fallout 4)

The Gatling laser is a weapon in Fallout 4.

Characteristics
The Gatling laser is a large two-handed weapon consisting of four rotating AER9 rifle barrels (three if the charging barrels are installed) that fire red laser pulses through two lenses. It uses fusion cores for ammunition. Each fusion core provides 500 shots. It has a high rate of fire but low accuracy, and its automatic reloading behavior can lead to an inventory full of partially-used cores if frequently swapping between weapons.

The Gatling laser has more damage and accuracy than any configuration of its ballistic equivalent, the minigun.

Variants

 * Final Judgment, carried by Elder Maxson during Airship Down or Precipice of War.
 * Aeternus, carried by the rogue knight during Amoral Combat.

Locations

 * One can be sold by Proctor Teagan aboard the Prydwen, as soon as the Sole Survivor reaches level 24. The modifications it comes with are also dependant on their level. Below level 30, Teagan generally sells an unmodded laser, at higher levels it may come with a charging barrels mod already installed.
 * Carried by Brotherhood of Steel knights and paladins, if they are wearing power armor at higher levels.
 * Commonly found in Airship Down.
 * One may be carried by Regi Blattaria, in a crippled house just west of Corvega assembly plant. Can only be acquired at higher levels and only after the Brotherhood have arrived in the Commonwealth.
 * Can be obtained from fallen Brotherhood of Steel soldiers during The Battle of Bunker Hill, especially in the face-off between them and the Railroad in Bunker Hill's utility basement.
 * Brotherhood soldiers are known to carry these weapons in random patrols or checkpoint defense missions. This however only occurs by siding with the Brotherhood in destroying the Institute.
 * Can be crafted using the energy weapon forge

Bugs

 * When a fusion core is spent fueling power armor, the Gatling laser will behave as if it has no ammo even if there are spare cores. This issue can be resolved by switching to a different weapon and switch back.
 * Should one choose to fire all 500 rounds of the core, upon reloading it will appear as though another core was not used. This is because of a bug caused by the repair bobblehead. Instead of increasing the Gatling laser's ammo capacity by 10%, it instead preserves roughly 10% of the fusion core's charge upon expending the 500 shots. This will cause a fusion core with a low charge to be placed in the inventory upon reloading, thus giving the illusion of infinite ammo. However, the cores are, indeed, being depleted of their charges.
 * Should the Sole Survivor switch from the Gatling laser to another weapon, not only will the partially depleted core be dropped in the inventory, but one will also find it does not use another core from the inventory when pulling it back out. This could be exploited to gain as many partially depleted fusion cores as wanted.
 * With a charging barrel, it is possible to speed up the rate of fire by switching to third-person view mode and crouching. The weapon will fire at an increased fire rate, but still not as close to the unmodded fire rate.
 * Companions using a Gatling laser with charging barrels will still retain the standard barrel's fire rate.
 * With the Laser Charging Barrel mod, it is possible to double and triple firing rates by clicking a second/third time while aiming down the sights and firing, thus negating the firing speed penalty.
 * Neverending Gatling Lasers use one Fusion core for a shot and make it possible to get loaded with infinite ammo. This is likely caused by the way the game converts fusion cores into Gatling laser ammo, as putting in one "magazine" is forced to render an infinite capacity (just like with standard weapons).

Behind the scenes
The Creation Club weapon skin packs "U.S. Army paints", "Brotherhood of Steel paints", "Institute paints", and "Vault-Tec paints", created by community modder Skidabaa in collaboration with Bethesda, identify this weapon by the name "XGL-105". This name can be seen on the upper left side of the receiver, opposite the fusion core receptible, alongside the serial code "4-⬤ MFB85500-I-▮▮".
