In the latest Call of Duty Zombies mode, there’s a locked vault that will give you access to some free loot.
Exploring Liberty Falls in Call of Duty: Black Ops 6 is an exhilarating experience, especially when you uncover the Easter egg that reveals the locked vault within the Savings and Loan bank, a point-of-interest on the map. Despite being a smaller Zombies map, its secrets invite players to find, unlock, and use the free randomized loot items hidden inside. To access this vault, you can start from either the left or right side of the map barrier, as both path choices cost the same.
Once inside, the locked vault door requires a combination to gain access to its valuable space. During my gameplay, I was thrilled when I first stumbled upon the loot vault; the adrenaline rush of finding the combination added to the excitement, transforming an ordinary match into a memorable adventure filled with unexpected treasures. This sense of discovery is what makes playing in Liberty Falls not just about survival, but about seeking out the hidden gems within its confines.
How to find the vault’s unlock code
To unlock the vault in Call of Duty: Black Ops 6’s Liberty Falls, players must gather a combination needed for access, which is scattered across hidden notes found around the map. You’ll need to find all three notes, each of which will provide two numbers for the 6-digit code. This numerical combination is unique and will change with each match, so be sure to inspect the notes diligently; the loot rewards for unlocking the vault are certainly worth your time.

The first piece of the code is located inside the bank, where you’ll discover a note on the countertop just outside the vault room.
The second piece can be found in Ollie’s comic book shop; head behind the counter, face the superhero statue, and then crouch or go prone to uncover a hidden note stuck inside a shelf.

Finally, the third piece awaits you at the bowling alley, specifically at the concessions counter, where the note lies underneath a bucket of beer. You can shoot or melee the bucket to make it disappear and reveal the final numbers needed to unlock the vault’s combination lock. My first attempt at gathering these codes was exhilarating; I remember the thrill of diving behind the counter in the comic shop to find that hidden note, which really adds an extra layer of excitement to the gameplay.
How to use the vault

Once you unlock the vault in Call of Duty: Black Ops 6’s Liberty Falls, you can enter anytime for a 40-second breather from Zombies, who can’t reach you inside. Use this time to loot, but watch the timer as you’ll be kicked out after it expires. On your first visit, you’ll get essence points, but the real rewards are keys dropped by Manglers and Abominations. These keys unlock security boxes with random loot, making each playthrough exciting. I’ve scored a killstreak with a common key, a rare weapon with a blue key, and even a Ray Gun Wonder Weapon with an Epic key, elevating gameplay on this intense map.
