A mysterious hatch has popped up in Fortnite.

It’s week two of Fornite Season 4 and a mysterious hatch has been found in the ground near the I3 sector of the map.

What’s it do? No one knows.

How do you open it? No one knows.

What’s inside it? No one knows… Although using the game’s replay camera, some players have found that there’s a very large area being locked off underground that you can see through the tiny windows.
