Subnautica 2 brings back a lot of features that were present in the first game. It adds new things, too. If you played the first one, you will feel right at home. If you are new, you do not need to worry. You can follow this guide and not miss a thing.

Initial Survival Steps

Look inside your Lifepod Storage right after you reach the surface. You will find Food and a First Aid Kit there. This is enough to keep you going for a bit. Next, go look around the Crash Zone. It is a safe area. Nothing here will kill you, though you might take a little damage.

Pick up everything you see. The starting area has Titanium, Copper, Quartz, Rotsac, and Metal Salvage. You will also find supply boxes. You do not always have to swim to the surface to get air. Look for an Oxygen Tunic. It lets out bubbles that fill your oxygen meter.

Managing Your Inventory

Storage is your biggest problem at the start. You will get full fast because you do not know what items are important yet. You will find Portable Storage boxes under your Lifepod. Do not take them with you when you go to collect resources in Subnautica 2.

Leave them inside or right outside your pod instead. Use them as boxes to hold extra stuff. Later, you can use them to move items to your base. The Fabricator can see inside these Portable Lockers and Wall Lockers. You can craft items without pulling resources out first.

Utilizing the Fabricator

Make Fins as soon as you can. You want to craft new items the moment you get the recipes. Crafting one thing often unlocks more things to make. The Fabricator has different tabs. The first tab has items you need to move the story forward.

The second tab is for materials you refine. Make at least one of each material to see what new recipes pop up. You can craft extra materials to save space in your inventory.

Just remember to save some raw items too. Do not turn all your Copper into Copper Wire. Also, you can turn Metal Salvage into four pieces of Titanium.

Monitoring Health and Nutrition

You have bars for Oxygen, Health, Food, and Water. Use Medical Gel Sac items or Pure Fiber to fix your health.

Find Water Slugs on surfaces to get water. You can turn them into Water Bottles or just drink from them directly. Drinking them raw gives you less water. Food is harder at the start. Cooked food will give you a Digestive Incompatibility warning in Subnautica 2.

It will not fill you up at all. Stick to Nutrient Bars until you fix this problem later in the game. If you die from hunger, you just respawn with 45 Food. You will drop your items, but you can swim back to get them.

Crafting Essential Tools

Make a Multitool before you go deep into Proteus. This tool lets you harvest Feather Kelp from caves and Fibrous Pulp from Gorgons. You can turn these into Fiber. The Multitool goes into your quick panel. You have five slots there.

If your main inventory gets full, you can put extra resources in any empty quick panel slots. Use your Fiber to make Threemoon Temaki.

This will solve your food problem. You just need to scan and collect three types of Harvest Moons first. You can also just push through the story until you get the Digestive Adaptation.

Scanning and Blueprints

You need a Scanner to move forward. Make it using Quartz and Acid. You can find Quartz on the seabed and inside Coral Domes. Look inside caves for Acid Pouches. They grow on purple flowers. These flowers have Medical Gel on top and three Acid Pouches on the sides.

If you grab the gel first, the plant shoots a bad cloud at you. Take the three Acid Pouches first. This stops the plant from attacking. Then you can safely take the gel. Use your Scanner on everything you see. Scan rocks, Flora, Fauna, and old base pieces in Subnautica 2.

Scanning broken pieces unlocks new blueprints. You can find a Flashlight and a Habitat Builder piece under your pod. Follow the power cable down to a building. Put a Battery in to turn the power on. Now you can scan for the Bio Lab.

Establishing a Habitat

Making the Habitat Builder is easy. You need two Titanium, one Glass, one Battery, and one Copper Wire. Equip it to start building. At first, you can only make corridors and hatches. Find a flat spot on the sea floor and build a hallway.

Put a hatch on it so you can walk inside. Next, place a Solar Panel on top. This gives your base power and air. One panel only makes a little power at night. Build a few of them so your machines work and you can breathe all night long.

Exploration and Advanced Gear

Tools use up Batteries. Carry an extra Battery when you go far. Press the change key to swap a dead battery for a fresh one. You will want an Air Tank and a Wakemaker vehicle to explore faster. Look for Wakemaker pieces near the tree that gives you the food adaptation.

You need Silver to build these items. Go west or northwest from that same tree. Look for a cable on the ground and follow it into a cave. You will find a lot of Silver inside. The cave has spots with air, so you can breathe easily while you search in Subnautica 2.
