Subnautica 2 First Hours Walkthrough: Minute-by-Minute Survival Guide

The Cicada went down 25 years ago. You weren't on it. You were printed yesterday by an AI called NoA from a backup of someone who died in the crash. The original colonists are gone. Something called the Proteavirus wiped them out. Your job is to figure out what happened.

This is the setup Subnautica 2 drops you into and it is, honestly, a lot. Here's how to survive the first three hours without getting distracted by the existential horror.

First 10 Minutes: Lifepod Assessment

Open the storage locker inside your pod. There's a Fire Extinguisher and some basic supplies. Keep the extinguisher. Fires destroy resources permanently and you'll need those resources later.

The Fabricator in your pod is already working. Check the crafting menu. You won't recognize most items. That's fine. Focus on the Scanner and Survival Knife for now.

Swim outside. Look around. The water on Proteus is different from 4546B. Greener. Thicker. More particulate. The Shallows feel alive in a way the first game's starting area didn't. Schools of tiny bioluminescent fish. Creeping things on the seafloor. Distant roars that you can't identify yet.

Don't swim far. Stay within 50 meters of your pod.

First 30 Minutes: The Scanner Rush

This is the only correct order for your first crafts.

Scanner first. Costs minimal titanium and a battery. Without it you can't identify anything. Blueprints come from scanning fragments, not from picking them up. Scan every piece of debris near your pod.

Survival Knife second. The Snapjaws in the Shallows aren't lethal but they're annoying. A couple slashes drives them off. The knife also harvests plant samples you'll need for silicone rubber.

Fins third. They noticeably improve swim speed. You'll be swimming a lot before you get the Tadpole. Every bit of speed compounds.

O2 Tank fourth. Doubles your breath time. The difference between reaching a cave entrance and drowning two meters short.

Materials to gather during this phase: titanium from metal salvage near the Cicada debris, copper from limestone outcrops, quartz from white crystals on the seafloor, and creepvine samples from the tall green plants at the edges of the Shallows. Get about ten titanium, five copper, five quartz, and four creepvine samples. That covers your first tools and your first base components.

First Hour: Repair and Mobility

Once you have the basics, craft a Repair Tool. You need Cave Sulfur for this. Look for small burrows on the seafloor. A creature called a Popcrab lives in them. When you approach it explodes out and swims away. Behind it is a sulfur deposit. Grab it before the crab comes back.

The Repair Tool fixes your lifepod's radio. Fixing the radio triggers NoA to start feeding you story locations. Coordinate data. Points of interest. This is how the narrative progresses. Don't ignore it.

Next priority: the Seaglide equivalent. On Proteus it's called a Propulsion Pack. Similar concept. Battery, copper wire, lubricant, titanium. It triples your swim speed and has a basic sonar. The sonar reveals terrain within maybe 30 meters. Not amazing but it stops you from swimming face-first into walls in caves.

At this point deploy a Beacon at your lifepod. Label it "HOME" or "POD" or whatever you'll recognize. The sea looks different from every direction. You will lose track of where your pod is. Everyone does.

Second Hour: First Base

The Propulsion Pack extends your range. Now you can scout for a base location. Look for a spot in the Shallows near a thermal fissure. You want to be above 100 meters so solar works but close enough to a heat source for thermal power later.

Your first base is minimal: one Multipurpose Room, one Hatch, one Fabricator inside, two Wall Lockers, and a Solar Panel on top. Total cost is maybe eight titanium, two quartz, one copper, and some miscellaneous. You can gather this in 20 minutes.

Do not build bigger. Do not add a Moonpool yet. Do not build a second room. The hull integrity system will punish you for expanding without reinforcement and you don't have the blueprints for reinforcement panels yet. Keep it small. Expand when you need the space.

The base gives you storage. The pod has maybe six slots. Your first base has 48 with two lockers. The quality of life difference is immeasurable.

Third Hour: Toward the Tadpole

The Mobile Constructor Bay is your next major goal. Blueprint fragments spawn near the larger Cicada debris fields in the Shallows. Look for floating platforms with construction arms. Scan three fragments and you unlock the blueprint.

Craft the Constructor Bay and deploy it on the surface. It's a floating platform that builds vehicles. The Tadpole requires titanium ingot, power cell, glass, lubricant, and lead. You should have most of these by now. If you're short on lead, check sandstone outcrops at the edges of the Vine Tangle biome.

Once the Tadpole is built, everything changes. Mobile oxygen. Storage. Speed. Protection. It's your home away from home for the next ten hours. Park it in a Moonpool eventually but for now just don't let it get destroyed. The respawn print system does not cover vehicles.

What to Skip

Don't chase the radio signals into deep water yet. NoA will ping you coordinates to the Fungal Basin and the Trench. These are 300 plus meters deep. You're not ready. Your Tadpole base chassis can't handle it and you don't have the Biomods to survive the threats.

Don't engage with the Axum story thread until you have Pressure Adaptation and at least one defensive Biomod. The alien structures down there are story-critical but the path to them passes through Lurkers.

Don't craft decorative base items. Posters, planters, aquariums. They're nice. They're also resource sinks. Get your functional base online first. Decorate at hour 20 when you're swimming in materials.

The first three hours are a race to the Tadpole. Nothing else matters as much. Once you have it, the entire ocean opens up.
