Aeternus

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

Characteristics
Unlike its smaller cousins, the laser rifle and laser pistol, the Gatling laser requires a great deal more power at a higher rate of consumption to maintain its rate of fire. As such, the heavy weapon is fueled by the same fusion cores that drive infantry power armor. The Aeternus is unique in that it has the Endless trait by default, requiring no reloads.

Locations

 * Nuka-Town USA: Received from the Rogue Knight fought in the Gauntlet.

Behind the scenes
In Latin, "aeternus" translates to "forever".
