How to Open the Vaulthalla Secret Room in Borderlands 3

There is a secret room in Borderlands 3‘s fourth story campaign add-on, Psycho Krieg and the Fantastic Fustercluck, however, you can only access this hidden area in Vaulthalla if you have completed specific tasks. In this Borderlands 3 guide, I will tell you where to go and what you need to do to unlock Vaulthalla’s secret loot rooms.

Key Takeaways

• A locked-off area containing multiple loot chests can be accessed at the end of the Vaulthalla map.
• Shooting multiple hidden yellow tiles throughout the map lowers the barrier and grants you access to the special loot room.
• A bonus loot area can be unlocked inside the hidden loot room!

About Vaulthalla’s Secret Room

Vaulthalla is the final map in Borderlands 3’s DLC: Psycho Krieg and the Fantastic Fustercluck where you fight against PsychoReaver. Defeating the final boss will reward you heavenly as you gain access to a special vault, however, you only have 60 seconds to claim these rewards.

There is a (mental) barrier in the back of the Vaulthalla loot room that blocks your access to the next room. This additional area isn’t required to finish the DLC but does contain multiple big loot chests that provide quality loot. Accessing this locked-off area is a Vault Hunter’s dream, however, you need to shoot multiple diamond-shaped tiles to unlock this part of the loot room.

Tips & Tricks

• The yellow glowing tiles turn green and a damage number displays on hit.
• Your crosshair will turn red when hovering over these diamond tiles.
• Equip an accurate sniper rifle with a decent scope to hit some of the smaller more hidden buttons.
• You can spend those 60 seconds looting the Vault as you can still trigger the buttons after the timer runs out.
• Use Buttstallion Milk from the Science Machine to increase the loot quality.
• If you missed any you can check the back wall of the Vault room. There are big diamond tiles on the wall that light up green if you hit all the buttons in a section. There are 4 tiles that correspond with the 4 sections of this map. If done correctly you successfully opened Valhalla.

Vaulthalla Puzzle Guide

The Vaulthalla map starts at The Lesionhall and this area is divided into 3 sections before you enter the treasure room. In this walkthrough, I will guide you through Vaulthalla and tell you where you can find all the buttons to solve this puzzle. There is a total of 12 buttons you need to shoot to open the gate to the secret loot area.

Section 1: Starting Area

The first 3 buttons can be found immediately at the start of the map. You don’t need to walk, just look around at these locations:

1. Directly in front of you at the top of the arch.
2. Left from you in the center of the side panel.
3. Right from you in the center of the broken side panel.

Shoot these 3 diamond tiles before moving on to the next section.

Section 2: Before the Boss

You can get to the second section by using the portal straight ahead from the start or by using the jump-pad on the platform to the side. There are 3 more buttons to find in this section of the map.

4. On the backside of the first arch in this section
5. On the ground to the right of the broken arch.
6. On the arch above the entrance to the boss arena.

You can proceed to the boss if you successfully hit all 6 switches.

Section 3: Boss Arena

You can find another 3 buttons in the boss arena. You can trigger these before/during/after your encounter with Psychoreaver. There is a small time window to shoot all 3 buttons before the boss can attack you. You can easily see all the buttons from the initial platform you drop onto.

7. High up on the wall behind you, if you just jumped into the boss arena.
8. Left on the side wall near the ground.
9. Right on the back wall near the ground.

If you have managed to trigger all 9 targets and defeated the Psychoreaver, a portal will appear and you can move on to the next location.

Section 4: Loot Room

There are 3 more switches hidden in the treasure room that you need to hit before the forcefield disappears. You can do this after the 60-second countdown timer because all the chests in this section will disappear once the timer runs out, therefore, you should use that time to actually loot this room because there are Red Chests in this area and they are known to provide high-quality loot and the chests in the additional locked-off room will remain even after the time has expired.

10. Use the jump-pads to get to the back left platform. A button is hidden on the block lying in the pile of gold.
11. A button is hidden underneath the floor of the center platform. Perform a slam on the cracked floor and smash your way through the ground to uncover this hidden section. Jump down from the platform containing the heavenly exit arch or perform a slam on the spot when having unlocked the “C’mon and Slam” Guardian Rank Perk.
12. The final button is on the wall opposite to the barrier.

The barrier will disappear if you successfully hit all 12 buttons. Happy Looting those 3 Red Chests and 5 big loot chests, however, there is more!

Secrets within Secrets

You will discover another locked-off room inside the initial locked-off area. This second barrier shields you from 2 Red Chests, 2 big loot chests, and the Achievement; “Ye Who Enter”. To unlock these treasures, you will need to locate and shoot another 12 hidden buttons, however, these are much harder to find but don’t worry; I have your back!

Entrance Wall

There are 6 small buttons hidden in the corners of the entrance wall, the one behind you when you enter the room.

Back Wall

There are 6 more small buttons hidden in the back wall.
