Location[edit | edit source]
The UP77 is found in University Credit Union at University Point. Inside the Credit Union, one will find a bank vault with a Novice-locked terminal. After hacking and opening the vault's door, the Sole Survivor will be in a room with some locked safes. On the second row, there will be a Master-locked safe; opening the safe will reveal a red button. Pressing it will open a wall to the right and on the large table in the middle of the room will be the UP77.
Notes[edit | edit source]
