In many ways, Borderlands 4 represents an evolution of its predecessors, ensuring the upcoming sci-fi looter-shooter is the most immersive entry yet. One such improvement over the previous versions is the inclusion of new Vault mechanics. This new gauntlet allows players to flex their combat prowess against hordes and unique foes, with great rewards awaiting them at the end.
Here is everything we know about Vaults in Borderlands 4 so far.

What are Vaults in Borderlands 4?

Vaults are a new side activity players will find during their open-world adventures across the new planet of Kairos. Lore-wise, Vaults have been a central component of the Borderlands universe as they are forgotten chambers with great rewards that are guarded by powerful alien beings.
While they have been accessible in past games, usually setting up the finale for the campaigns, they function a tad differently here.
To access Vaults, fans will have to jump through a few hoops. This requires tracking down several Vault Fragments scattered around Kairos. Finding all the Fragments will allow the creation of a Vault Key, which will allow players to enter this gauntlet. Interestingly, as recent Borderlands 4 previews suggest, this can be done even at player levels as low as 20.
That does not mean they will be a breeze, as the foes inside can hold their own against the Vault Hunters. This might feel reminiscent of the Maliwan Takedown endgame side content in Borderlands 3. As such, players will need to be prepared when they go in.
This especially rings true for the final Vault boss encountered deep inside the Vault. This powerful enemy boasts various mechanics that make boss fights more dynamic than ever in the series' history while also amping up the sense of action and immersion. Overcoming the boss will not just reward players with new loot, but also new ability upgrades.
The upcoming entry boasts a sandbox environment now, so enhanced abilities should allow for smoother traversal across the world. Furthermore, players can also choose to immediately reset the Vault to farm for the unique gear drops they desire. This should let players adjust progression in the direction they want to be to tackle most other open-world activities.
Borderlands 4 arrives on September 12, 2025, for PC, PS5, and Xbox Series X|S. A Nintendo Switch 2 port is also slated for a launch later in 2025.
