Aeternus

Aeternus is a unique weapon in the Fallout 4 add-on Nuka-World.

Characteristics
Aeternus is a unique Gatling laser that bears the "never ending" legendary effect.

Although it uses the "never ending" legendary effect, its actual effect gives the weapon true unlimited ammo. It will use a portion of a fusion core when first fired, but the core's charge will not decrease again while using Aeternus.

There is a big but in using this weapon every time you you switch weapons and come back to Aeternus you will consume 79% of another fusion core. Teleporting has the same effect as switching weapons.

Variants

Location
