Finding the Blueprints

Start at your Lifepod and swim straight south. Keep swimming south until you reach a large clam-like animal.

You can enter this creature, but you must be careful because touching its tentacles triggers a mechanism that causes its mouth to shut. If it starts closing, move out quickly and wait a few moments for it to reopen.

Inside this creature, you will spot the first piece of the Portable Oxygen Generator on the ground for you to scan in Subnautica 2.

The second piece is located right in the center of the area, but it is hidden under a piece of Metal Scrap Plating. Pick up the plating to reveal the blueprint underneath and scan it.

Gathering Materials and Crafting

While you are inside the creature, you should also look around for Lithium. You will need a Sonic Resonator to break the resource deposits in this area.

To finally craft your Portable Oxygen Generator, take your blueprints back to base and combine three pieces of Titanium with two pieces of Lithium in Subnautica 2.
