Final Judgment

The Final Judgment is a unique weapon (Gatling laser) in Fallout 4 that is carried by Arthur Maxson during the quest Airship Down.

Characteristics
Bears the Rapid effect, which grants 25% faster fire rate and 15% faster reload. It uses fusion cores as ammo. With the overcharging barrels subtracting 75% of the rate of fire, the additional 25% rate of fire from the Legendary Modification yields 50% rate of fire which means that it fires two times as fast as a normal overcharging barrels Gatling Laser.

Variants

 * Gatling laser

Locations
It is carried by Arthur Maxson during the quest Airship Down. Maxson will appear with a full set of T-60f power armor and the weapon aboard a Vertibird while the Institute synths are trying to hack Liberty Prime. There is a small possibility to recover this weapon after the Prydwen is destroyed but it may glitch under the wreckage of the Prydwen (some BOS enemies might glitch under the wreckage).

If you are currently siding with the Minutemen and you want to obtain this weapon without siding with the Brotherhood of Steel, just continue the Railroad quests until you receive the quest Precipice of War, but do not go to Police Station. Instead go to The Prydwen, and kill Elder Maxson in order to receive Final Judgment.

Alternately you can still acquire the weapon after completing Precipice of War by continuing with Rockets' Red Glare; engage the Brotherhood of Steel members in the main deck area, plant the explosives, and then you should get ambushed by Maxson and two unnamed Brotherhood of Steel members (one will have power armor and a Gatling laser) as you exit the Prydwen via the command deck. Be prepared as they'll open fire as soon as loading completes, there's very little cover available, and the energy weapons can deplete your health very quickly.

Maxson also uses it during The Nuclear Option, but it is unobtainable.

Bugs

 * This weapon may not spawn in Maxson's inventory. Cause is unknown. Elder Maxson will use it to attack the player, but it won't show up in his inventory after his death, so watch it carefully when Elder dies; weapon will fall out of his hands and will be available as is.
 * Reloading may not correctly consume fusion cores. If you reload the weapon before fully emptying the magazine, the game will never decrement your total number of fusion cores, effectively allowing infinite ammo.
