Gatling Laser (Fallout 4)

The gatling laser is a weapon in Fallout 4.

Characteristics
The gun is a large, two-handed weapon consisting of two rotating barrels that fire red laser beams. It uses fusion cores for ammunition. Each fusion core provides between 250 and 500 shots, depending on how many points the player character invested in the Nuclear Physicist perk. It has a high rate of fire but low accuracy, making it more useful for large numbers of close enemies.

Automatic reloading behaviour can lead to an inventory full of partially-used cores if frequently swapping between weapons.

Variants

 * Final Judgment

Locations

 * One sold by Proctor Teagan aboard the Prydwen at higher levels.
 * Carried by Brotherhood of Steel Knights & Paladins, if they are wearing Power Armor at higher levels.
 * Commonly found in Airship Down.
 * Elder Arthur Maxson carries a unique variant (Final Judgment) during Airship Down.
 * Can be found as legendary loot item above level 40.

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.
 * 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.
 * The legendary prefix, Neverending, causes the gatling laser to use no ammo.
 * With an overcharged 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.
