Prototype UP77 "Limitless Potential"

The Prototype UP77 "Limitless Potential" is a unique weapon in Fallout 4.

Characteristics
This unique laser pistol features unlimited magazine capacity. The player character needs the Gun Nut perk to improve this weapon. Do not get confused, it is a limitless magazine, not limitless ammunition. Your gun never reloads but still runs off of Fusion Cells.

Locations
The UP77 is found in University Credit Union at University Point. Inside the Credit Union you will find a bank vault with a Novice terminal, After hacking and opening the vault's door you will be in a room with some lock pick-able safes. On the 2nd row there will be a master locked safe, If you open the locked safe there will be a button pressing it will open a wall to your right and on the large table in the middle of the room will be the UP77. (PC NOTE): If you are to come into the Credit Union opposite of the teller's cage and you use the TLC console command to go into the safe where Prototype UP77 is; it will not be there. For the gun to spawn you must enter through the door that goes to the teller's side which in turn requires you to hack a Novice Terminal.
