In Subnautica , the “black box” is in the Aurora , inside the Black Box Room near the Prawn Bay. The usual route is to enter the Aurora, reach the Prawn Bay, and look for the underwater passage/tunnel that leads to the terminal where you can download the black box data.

How to find it

  1. Go into the Aurora after it has become accessible.
  2. Make your way to the Prawn Bay.
  3. Look underwater near the right side of the bay for the hidden tunnel/entrance.
  4. Follow it to the Black Box Room and interact with the terminal.

Useful note

A lot of players call it the “black box,” but in the base game the actual data is obtained from a data terminal in the Aurora’s laboratory/black box area, not from a separate item you pick up.

Code mention

One source says the door code for the black box room is 6483.
