Prototype UP77 "Limitless Potential"

The Prototype UP77 "Limitless Potential" is a unique energy weapon that can be found and obtained within the Commonwealth, in Fallout 4.

Background
The weapon was the brainchild of Leslie Mathews and Curtis Marsh, graduate students aiding Prof. Campbell in his energy research. Although originally working under his strict supervision, Campbell eventually gave them unrestricted access to the laboratory to compensate for the Dean's interference. Their work focused on plasmon containment and increasing energy efficiency in nuclear reactors, and they eventually achieved a breakthrough in October, focusing the electron beam down to around 200 nanometers, achieving improved efficiency and grouping. Although the result was ill-suited for reactor containment, it did promise improved energy consumption for industrial applications and weapons.

However, their research would have no effect on the war effort. On October 23, as Mathews and Marsh were presenting their findings to Sergeant Rivera, the team's liaison, the nuclear attack on the United States began. The sergeant left the laboratory to investigate, asking the young researchers to stay behind until it was safe. He did not return - and Campbell, originally scheduled to arrive around noon, never reached the laboratory. The two researchers stayed underground for the next several weeks, ignoring the explosions continuing above ground. To pass the time and preserve their sanity, they focused on their research, tightening the electron beam on the laser using modified parabolic reflectors. The stocks of food and water kept on site by Campbell definitely helped, allowing them to survive for weeks. Finally, several weeks after the Great War, the two managed to tighten the wavelength down to around 75 nanometers and achieving an impressive capture rate and tremendous power capacity for each of their prototypes. At that point, however, they were already out of food and almost out of water, forcing the researchers to abandon the lab, after exchanging marriage vows. They left this unique laser rifle behind in the safe.

Characteristics
This unique laser rifle features an unlimited ammo capacity, and as such, never needs to be conventionally reloaded, so long as the Sole Survivor keeps a consistent store of fusion cells within their inventory.

Variants

 * Pistols
 * Laser pistol
 * Survivor's Special
 * Rifles
 * Laser rifle
 * Righteous Authority
 * Wazer Wifle
 * Level-dependent

 * Prototype UP77 "Limitless Potential"

Locations
The UP77 is found at University Point, inside of the Credit Union, where the Sole Survivor can discover a bank vault locked behind a Novice terminal. After hacking through the vault door, the Sole Survivor will find themselves inside, where they will have access to the safety deposit safes within. Upon discovering a Master locked safe, a red button will be revealed, and upon pressing it, a hidden room will become accessible, which leads to the prototype laser rifle. This weapon can serve as an alternative to the Wazer Wifle.
