Subnautica 2 Base Guide: Best Locations and Essential Upgrades
You finally unlocked the Habitat Builder, but slapping a metal tube next to your Lifepod is a massive mistake.
Your starting pod is a temporary crutch. It already has a basic fabricator and a NoA terminal, so building your first real home right next to it is a complete waste of resources. The story naturally pushes you eastward. If you build too close to your crash site, you are signing up for agonizingly long return trips every time your pockets get full. You need to push out into the ocean and claim a proper plot of land.
Escaping the Corridors
Before you start planning your dream home, you need to realize that your basic Habitat Builder only knows how to make metal corridors. Living in a tube is miserable and leaves zero space for large machinery. You need to track down the Room recipe data card.
The Southwest Crater Dive
Go southwest from the Lifepod and swim over the edge of the cliff. Follow the right side crater wall until you pass some colony wreckage hanging over the edge. Straight ahead and below you, you will spot a ruined colony building. Swim down and go inside.
The data card you need is sitting in the backroom. This is a deep dive. Before you attempt this, I highly recommend crafting a Standard Air Tank, keeping a few Air Bladders on hand, and bringing a Wavemaker so you can swim fast enough to avoid drowning in the dark.
Picking the Perfect Real Estate
Now that you can actually build a decent structure, you need to find a flat, unobstructed plot of land. Do not try to force a foundation over large corals or heavily contested leviathan territory.
Go East and Find a Current
As I mentioned, early events like Wander's Blackbox happen near the spawn, but the game quickly directs you further east. That is where you want to settle.
Try to find a spot with a natural underwater current nearby. These look like flowing blue wind tunnels. You will eventually want to drop a Hydroelectric Turbine inside one for infinite energy. I already covered how to harness these currents in my Subnautica 2 Power Grid guide. You also want a location rich in basic building resources like titanium, copper, and fibrous pulp so you do not have to swim miles just to make a locker.
Essential Interior Upgrades
A powered room is useless if it is completely empty. You need to prioritize a few specific facilities to actually progress your tech tree and survive longer excursions.
Base Fabricator and Storage
Your Lifepod fabricator is severely damaged and restricts your crafting. Building a Base Fabricator inside your new home removes all those limitations, letting you manufacture complex items like Wiring Kits and System Chips.
Next, you need massive amounts of storage. Throwing your junk into tiny Portable Lockers will drive you insane. Build a few Wall Lockers or Floor Lockers immediately. Nearby facilities can pull materials directly from these containers, making your crafting flow incredibly smooth.
The Processor and Biobed
You need a Processor to create ingots, strong acid, and biofuels. You can conveniently scan the blueprint for this machine in the exact same backroom where you found the Room data card. Ingots are strictly required to craft the Sonic Resonator, which you need to clear Bloom Biofilm and access new biomes.
Finally, you need a safe place to wake up when things go wrong. Scan the Biobed in the Colonist Bunker located 220 meters southeast of the Lifepod at a depth of 42 meters. Building a Biobed in your base gives you a permanent respawn point.
Planning for the Moonpool
You will eventually want a vehicle to explore the deeper, more dangerous waters. That means you need to leave room for a Moonpool and a Tadpole Dock.
Mind Your Clearance
The Moonpool must be built directly into the floor of a standard room. Before you construct your base flat against the seabed, make sure at least one room is suspended high off the ground. There needs to be enough vertical space between the Moonpool hatch and the seafloor for your Tadpole to physically fit underneath it. If the gap is too small, the game will literally block you from placing the vehicle fabricator.
Facility Crafting Costs
Before you head out on a massive resource run, here is a quick breakdown of what you need to stockpile for your most important interior facilities.
