Gatling Laser (Fallout 4)

The Gatling laser is a weapon in Fallout 4.

Characteristics
Uses fusion cores for ammunition. Each fusion core provides between 250 and 500 shots, depending on how many points the player invested in the Nuclear Physicist perk.

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 you 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 your inventory upon reloading, thus giving the illusion of infinite ammo. However, the cores are, indeed, being depleted of their charges.
 * Should you switch from the Gatling Laser to another weapon, not only will the partially depleted core be dropped in your inventory, you will also find it does not use another core from your inventory when you pull it back out. This could be exploited to gain as many partially depleted fusion cores as you want.
