Room Blueprint details
Room Blueprint location
The old habitat is a massive underwater base situated roughly 350 meters north of your starting lifepod. It stands out clearly in the aquatic environment due to its sheer size, appearing as a giant abandoned facility resting beneath the waves. While the main structure towers above the seabed, the lowest sections provide the necessary access points to explore its flooded interior.

Exit through the front door of your lifepod and orient yourself to face directly north.

Step 2
Swim due north for approximately 350 meters.

Until you spot the giant underwater base known as the old habitat.

Step 3
Swim towards the bottom right section of the habitat.

And go completely underneath the lowest room.

Step 4
Locate the hole in the floor of the structure.

And jump through it to enter the flooded base.
Step 5
Move straight into the first room.

Then take an immediate left and follow the corridor all the way to the end where a ladder is located.

Step 6
Climb the ladder straight up through the first room and continue up into the second room above it.

Step 7
Head into the main cockpit area.

Look in the corner to find the interaction point for the blueprint.
