It wouldn’t be Fortnite without secret loot spots and hidden vaults, and Chapter 7, Season 1 is full of them. Players who have been able to explore the depths of this new map might have noticed a few interesting features, including legendary loot in a waterfall, mysterious locked doors, and chests hidden behind breakable walls.
This season, underground tunnels have more to offer than a fun way to traverse the island. Hidden within one of the collider corridors is a rare chest locked behind a vault door, and the only way to get inside is with an Unstable Element.
How To Find And Use The Unstable Element
Underneath Innoloop Labs in the center of the Fortnite Chapter 7, Season 1 island, are a series of connected tunnels, one of which (Collider Corridor X) has a mysterious locked door with a rare blue chest behind it that you can hear from the outside. The only way into this locked door is with a special key: the Unstable Element.
You can traverse these Collider Corridors by interacting with the large hand icon buttons at the end of each area. The corridors also give off a pulse of energy that, when it rushes past you, grants you up to +50 shield.
The buttons light up green when it is safe to travel, and red when the destination is in the storm and will cause you damage.
To unlock the secret vault in Collider Corridor X, visit Innoloop Labs and go to the center where you will find a large floating crystal. Jump down through the glass and into the Collider Corridor below. You should get a pop-up showing you have entered Collider Corridor X.
Head to either the left or the right of the tunnel to find one of the buttons. To gain the Unstable Element, you need to first make sure you have a free slot in your inventory. The Unstable Element won’t appear unless it has space to do so.
When you have a free inventory slot, interact with the button to go to the next corridor, and see that the Unstable Element has appeared in your inventory. Travel straight back to Collider Corridor X.
Take the Unstable Element to the locked door in the middle of the corridor, and unlock it to find a rare chest. Inside the chest will be a variety of high-rarity items and weapons such as:
- Chug Jug
- Epic or Legendary Holo Rush SMG
- Epic or Legendary Arc Lightning Gun
- Self-Revive Device
- Epic or Better Enforcer Assault Rifle
- Rare or better Vengeful Sniper Rifle
