If you want to know how to open the Mega Maze Vault in Fortnite, you need to find the invisible container moving through the maze, destroy it to collect a Temple Vault Key, then use that key on the pedestal at the western side of Mega Maze. Doing so opens the hidden vault chamber behind the wall.
Knowing how to open the Mega Maze Vault in Fortnite is useful because the vault is hidden inside one of the less obvious Chapter 7 Season 4 locations. Unlike the Stone Sanctum Temple Vault, Mega Maze only requires one Temple Vault Key, but finding that key is the real challenge.
How to Open the Mega Maze Vault in Fortnite
To open the Mega Maze Vault in Fortnite, follow these steps:
- Travel to Mega Maze.
- Get above the maze walls if possible.
- Look for the trail left by the invisible moving container.
- Follow the container until you get close enough for it to become visible.
- Destroy the container.
- Collect the Temple Vault Key.
- Head to the western side of Mega Maze.
- Go up the stairs and find the pedestal.
- Use the Temple Vault Key on the pedestal.
- The hidden vault door opens in the wall behind it.
You only need one Temple Vault Key for the Mega Maze vault.
Where Is the Mega Maze Vault in Fortnite?
Mega Maze is an unnamed location in the southern half of the Chapter 7 Season 4 map.
The actual vault entrance is on the western side of Mega Maze, close to a set of stairs and the Temple Vault Key pedestal.
You will not immediately see an obvious vault door when you arrive.
The hidden entrance appears once you use the key on the pedestal.
Where to Find the Mega Maze Temple Vault Key
The hardest part of how to open the Mega Maze Vault in Fortnite is finding the Temple Vault Key.
The key is inside an invisible container moving through the maze.
You can spot it more easily by looking for the trail it leaves behind.
Nintendo Life recommends viewing the maze from above, either while dropping in from the Battle Bus or by climbing onto the maze walls.
From that higher position, the moving trail is much easier to follow.
Is the Mega Maze Temple Vault Key Invisible?
The container is initially invisible, but it becomes visible when you get close enough.
That means you are not trying to destroy something you can never actually see.
Instead:
Find the trail → follow it → get close → container becomes visible → destroy it.
Once destroyed, the Temple Vault Key drops out.
Does the Invisible Container Follow the Same Route?
Current coverage says the moving container appears to follow a fixed route around the maze.
That is useful if you lose sight of it.
Rather than running randomly through Mega Maze, you can wait for the trail to loop back around.
This makes learning how to open the Mega Maze Vault in Fortnite much easier once you know what you are looking for.
How Many Temple Vault Keys Does Mega Maze Need?
You only need one Temple Vault Key to open the Mega Maze Vault.
That makes it simpler than the Stone Sanctum Temple Vault, which requires two keys.
The challenge at Mega Maze is not the number of keys.
It is finding the moving invisible container carrying the key.
Where Do You Use the Mega Maze Temple Vault Key?
Once you have the Temple Vault Key, head to the western side of Mega Maze.
Look for the stairs in that area and go up them.
You will find the pedestal where the key needs to be inserted.
Use the Temple Vault Key on the pedestal and a secret door opens in the wall behind it.
That gives you access to the vault chamber.
Why Is the Mega Maze Vault Not Opening?
If you know how to open the Mega Maze Vault in Fortnite but the vault is still closed, check whether you have actually used the key on the correct pedestal.
Simply carrying the Temple Vault Key is not enough.
You need to:
- Reach the western side of Mega Maze.
- Find the stairs.
- Locate the pedestal.
- Insert the Temple Vault Key.
The hidden wall only opens once the key has been used.
What Is Inside the Mega Maze Vault?
Current Chapter 7 Season 4 vault coverage confirms that the vault contains rare loot once opened.
The exact contents can vary, so it is better not to promise one specific weapon or item from every run.
The main benefit is gaining access to a hidden loot chamber after completing the Temple Vault Key puzzle.
Is Mega Maze the Same as Stone Sanctum Vault?
No.
There are currently two discovered Temple Vaults in Chapter 7 Season 4:
- Stone Sanctum
- Mega Maze
They use different puzzles.
At Stone Sanctum, you need two Temple Vault Keys and use them on two central pedestals to drain the water.
At Mega Maze, you need one Temple Vault Key from the moving invisible container and use it on the western pedestal.
Where Is Mega Maze on the Fortnite Map?
Mega Maze is an unnamed location rather than a major named POI.
It sits in the southern half of the Chapter 7 Season 4 Island.
Because the name does not appear prominently like Stone Sanctum, it is worth marking the general southern area before jumping if you are specifically trying to open the vault.
Best Way to Find the Mega Maze Vault Key
The easiest method is to approach from above.
When you are dropping into Mega Maze, look down across the maze for the trail left by the invisible container.
If you miss it during the landing:
- Climb onto the maze walls.
- Scan for the moving trail.
- Follow the trail from above.
- Drop down when you are close.
- Destroy the container when it appears.
This is much faster than running through every corridor hoping to accidentally collide with it.
