Subnautica Survival Tips for Beginners
So, you’ve just splashed down in your lifepod, and the ocean’s staring you down. Don’t panic. Here’s how to stay alive:
- Oxygen: It’s your number one priority. Keep an eye on that oxygen bar when you dive. Run out, and it’s game over. Craft an Oxygen Tank ASAP to stay underwater longer.
- Food: Grab fish like Peepers or Bladderfish with your hands or a Grav Trap. Cook them in a Fabricator. Raw fish won’t fill you up as much.
- Water: Snag some Bladderfish and turn them into Filtered Water. Later, a Water Filtration Machine keeps you hydrated without the hassle.
- Health: Watch out for angry critters and spiky plants. A First Aid Kit (1 Fiber Mesh) fixes you up quick.
When I first played, I freaked out every time I heard a weird noise underwater. Trust me, you’ll get the hang of it. Start small, and soon you’ll be swimming like a pro!
Essential Crafting Recipes in Subnautica
Crafting is the heart and soul of survival in Subnautica. It’s not just about making tools. It’s about turning the alien world’s resources into everything you need to thrive, from basic gear to advanced vehicles. The Fabricator is your go-to device, found in your lifepod and later in your base, where you’ll craft most items. As you explore, scanning fragments and wrecks unlocks new blueprints, expanding your crafting options and pushing your adventure forward.
Here’s a table of must-have items to get you started:
Item | Recipe | Use |
---|---|---|
Oxygen Tank | 3 Titanium | Gives you more air to explore deeper |
Fins | 2 Silicone Rubber | Makes you swim faster |
Knife | 1 Titanium, 1 Silicone Rubber | Cuts plants and fights off small pests |
Scanner | 1 Battery, 2 Titanium | Unlocks new blueprints by scanning stuff |
Repair Tool | 1 Silicone Rubber, 1 Cave Sulfur, 1 Titanium | Fixes broken gear and vehicles |
Seaglide | 1 Battery, 1 Lubricant, 1 Copper Wire, 1 Titanium | Zooms you around the ocean |
Quick Tip: The Scanner is your best friend. Scan everything, wrecks, fragments, even creatures, to unlock better gear. You’ll thank me later!

Building Your Base in Subnautica
Tired of floating around? Build a base! It’s your safe spot to store stuff, craft, and chill. Here’s the rundown:
- Where to Build: Pick a place with lots of resources and fewer monsters. The Safe Shallows or Grassy Plateaus work great for starters.
- What You Need: Start with a Foundation, then add Multipurpose Rooms, Corridors, and a Hatch to get in and out.
- Power Up: Use Solar Panels in shallow spots or Thermal Plants near hot vents for deeper bases.
- Cool Add-Ons: Throw in a Fabricator, Battery Charger, and Modification Station. Later, a Moonpool lets you park vehicles, and a Scanner Room finds resources.
Building my first base felt like a huge win. Add some windows and plants. It’s your underwater home away from home!

Exploring Subnautica’s Biomes and Creatures
The ocean’s packed with wild places to check out. Each biome has its own vibe, resources, and dangers. Here’s a closer look at some key ones:
Safe Shallows
Your starting zone, a calm, sunny area with sandy floors and colorful coral tubes. It’s loaded with basics like Titanium from limestone outcrops and Quartz for glass. Fish like Peepers and Bladderfish swim around, easy to catch for food or water. Gasopods are the main threat. They puff out toxic clouds if you get too close, so give them space!
Kelp Forest
Tall green kelp towers stretch up from the seafloor, swaying in the current. Stalkers, shark-like predators, roam here. They’re obsessed with metal salvage and will steal it if you drop it, though you can toss fish to distract them. Harvest Creepvine Seeds from the kelp for crafting and dig into sandstone chunks for Silver Ore. The eerie rustling of kelp adds a spooky vibe!
Grassy Plateaus
Expansive fields of red grass cover this biome, broken up by rocky arches and sandy patches. Biters nip at you if you linger, and Sand Sharks burrow up from the ground to attack. It’s a hotspot for wrecks, which hold fragments for stuff like the Seamoth or Mobile Vehicle Bay. Keep moving. It’s wide open and easy to get ambushed!
Mushroom Forest
Giant mushroom trees dominate this biome, their glowing caps lighting up the seafloor. Mesmers, hypnotic fish with dazzling patterns, try to lure you in for a bite. Shake off their trance by looking away. You’ll find Gel Sacks for aerogel and Lithium in shale outcrops, both crucial for late-game gear. It’s a surreal, beautiful place worth exploring slowly.
Blood Kelp Zone
A deep, shadowy biome with blood-red kelp and faint, ghostly lights. Warpers teleport in to hunt you, and Ampeels zap anything nearby with electric shocks. It’s dangerous but rewards you with Blood Oil for polyaniline and Deep Shrooms for advanced recipes. Only venture here with a vehicle and plenty of supplies. It’s not for the faint-hearted!
Explorer’s Note: My first trip to the Mushroom Forest blew my mind. The glow, the giant trees, it’s unreal. Take a Seaglide or vehicle to move fast and stay safe!

Advanced Subnautica Strategies: Vehicles and Upgrades
Once you’ve got the basics, vehicles and upgrades open up the deep sea. Here’s how to master them:
- Seamoth: A nimble little sub perfect for zipping around. Boost its dive depth from 200m to 900m with Depth Modules (crafted at a Modification Station). Equip a Sonar to reveal hidden caves in murky water, and a Storage Module for extra loot space. The Perimeter Defense System sends out a shock to scare off attackers, great for Stalkers or Bonesharks!
- Cyclops: This hulking submarine is your mobile fortress. It can store gear, recharge batteries, and even dock a Seamoth or Prawn Suit. Keep spare Power Cells on hand, craft them with 2 Batteries and 1 Silicone Rubber, then recharge at base. Use Silent Running to creep past Reapers undetected, or launch Decoys (crafted at the Cyclops fabricator) to lure leviathans away. Watch your hull strength, crashes or attacks can spring leaks!
- Prawn Suit: A tough exosuit for deep-sea work. The Drill Arm lets you harvest large deposits like Copper, Gold, or Diamonds, just hold the drill on the node until it breaks apart. Jump Jets boost you up cliffs or out of danger, while the Grappling Arm lets you latch onto surfaces and swing across gaps. Pair it with a Thermal Reactor module near heat vents for endless power.
Pro Move: Stack upgrades like Hull Reinforcement to tank more hits or Engine Efficiency to stretch power longer. Facing a leviathan? Lure it away with a decoy, then jet off, parking in safe zones like a Moonpool saves repairs later!
Subnautica Story Guide: Key Events and Locations
There’s a gripping story hidden beneath the waves, and it’s worth uncovering. Here’s how to follow it without spoiling the surprises:
- Lifepod Signals: Your PDA will alert you to other lifepods. Investigating them reveals story clues and sometimes useful gear.
- Degasi Bases: These abandoned bases tell the tale of previous survivors. Their logs provide backstory and hints about the planet’s mysteries.
- Alien Structures: Deep in the ocean, you’ll find ancient alien tech. These structures are key to understanding the planet’s history, and finding a way home.
The story unfolds naturally as you explore, so take your time. The ocean’s full of secrets, and piecing them together is half the fun!
Handy Tips for Subnautica Players
Newbies often wonder where to find rare stuff like Diamonds. Check Shale Outcrops in places like the Grand Reef or Blood Kelp Zone, a Scanner Room with range upgrades makes it a breeze to locate them. Stuck on the Captain’s Quarters Code? It’s 2679, don’t tell anyone I told you! Reapers giving you nightmares? Dodge them with a Seamoth’s Defense System or the Cyclops’ Silent Running, a Stasis Rifle can freeze them if you’re desperate. For Magnetite, head to the Mountains, Jellyshroom Caves, or Blood Kelp Zone and scan with a Mineral Detector. Curing the infection ties into the story, follow lifepod signals and alien clues to crack it.
