How To Unlock The University Credit Union Vault
Requires Master-level Lockpicking
Heading down the next set of stairs, open theSecurity Gate to find another Novice-level Terminal. This must be used to hack open the Credit Union bankvault inFallout 4. Alternatively, those who want to save their Bobby Pins can access the vault by using Gerald’s Vault Password.
Gerald’s Vault Password can be found in the employee area, kitchen, and break room. As there are quite a few vaults and terminals within this building,Streamer Houseon YouTube recommends leveling up your lockpicking skills and getting the locksmith perk to ensure you don’t miss out on any key items.

When you unlock and enter the vault, you will find several safes, some already open, while others are broken. Among them, you will see alocked safe in the second row of the right-hand wallthat requires Master-levellockpicking inFallout 4.
Within the open and locked safes, a plethora of extra items are worth taking, including an Ammo Box containing Plasma Cartridges, Caliber, and Rounds. You can also pick up Nuka Cola, Rad-X, and several crafting materials. Two more locked Advanced-level and Master-level safes also contain ammunition and valuable materials.
Master-level is the highest-ranking lockinFallout 4and, therefore, the hardest to open. If you haven’t leveled up this skill yet, you won’t be able to use your Bobby Pins to open the safe. To bypass this issue, look for Campbell’s Safe Password, which can be found in the student records terminal in Sedgwick Hall.
Sedgwick Hall is another Institute faction close by, within University Point. You can find the key card to open the Master-lock safe by heading through a broken wall hole within the main first-floor entrance.

One of the unique features of the Prototype UP77 ‘Limitless Potential’weapon inFallout 4is that it possesses the Never Ending effect, which grantsunlimited ammo capacity. This shouldn’t be confused with having unlimited ammo, as it utilizes Fusion Cells, like other laser weapons found in the wasteland. Instead, it has an unrestricted Magazine, eliminating the need to reload when firing.
Not only does this make you faster when dealing damage in combat, but it also means that players will never have to stop shooting to reload.
