Subnautica: 10 Essential Tips for Surviving the Ocean Planet

Introduction

Subnautica drops you into an alien ocean with little more than a lifepod and a vague distress signal. The vast, beautiful, and terrifying underwater world is full of wonders and dangers. Whether you're a newcomer or a returning survivor, these ten essential tips will help you manage resources, avoid leviathans, and build a base that could withstand a sea dragon.

1. Stay near the lifepod initially

Your lifepod is your safe haven. It contains a fabricator, a radio (which receives important story signals), and a storage compartment. Stay within a few hundred meters until you craft a repair tool and a scanner. The shallows are rich in basic resources like titanium, quartz, and copper. Scan everything you see to unlock blueprints.

2. Manage your oxygen carefully

Oxygen is your most precious resource. Always keep an eye on the gauge. Early on, craft a high-capacity O2 tank and fins for faster swimming. Build a few floaters to mark cave entrances or danger zones. When exploring wrecks, place beacons or use pathfinder tool (if you've scanned it) to avoid getting lost. Remember: you can breathe inside your base or a vehicle, so plan your exploration routes accordingly.

3. Craft a scanner and habitat builder as soon as possible

The scanner is crucial for unlocking new blueprints. Scan any fragment you find, even duplicates – some require multiple scans. The habitat builder lets you construct a basic base. Build a simple tube with a power source (solar panel if above 10m, or thermal if near a vent). A base provides storage, food/water via indoor growbeds, and a place to recharge your tools.

4. Prioritize food and water

You need to eat and drink regularly. Catch fish with your knife or a grav trap. The best early foods are Peepers and Boomerang fish. For water, craft a bladderfish or build a water filtration machine once you have advanced materials. Alternatively, plant Bulbo Tree or Chinese Potato in a growbed for a renewable food source.

5. Don't panic around dangerous creatures

Subnautica's creatures are aggressive but often avoidable. Stalkers are curious and may attack if you take their metal salvage. Sand Sharks can be detected by the sand clouds they kick up. If a Reaper Leviathan grabs your seamoth, use console commands? No, just use the perimeter defense system or boost away. Most creatures can be outrun or dodged. Learn their movement patterns.

6. Build a Seamoth early

The Seamoth is your first submersible vehicle, providing speed, storage, and oxygen. Craft it as soon as you find the blueprints (wreck in the Safe Shallows or Kelp Forest). Upgrade it with storage modules, a depth module, and possibly a perimeter defense system for leviathan deterrence. Never leave your seamoth unattended near hostile creatures – it can be destroyed.

7. Plan your base location wisely

Build your first base near the safe shallows but close to a resource-rich biome like the Kelp Forest or Grassy Plateaus. Consider proximity to thermal vents for power, or to a cave entrance for later progression. Build multipurpose rooms: one for a fabricator, one for storage, one for a bioreactor. Use foundations for stability and reinforcements to avoid hull breaches.

8. Explore wrecks thoroughly for fragments and data

Wrecks are full of valuable blueprints, scannable items, and lore. Bring a laser cutter, a propulsion cannon, and a repair tool. Some wrecks have multiple entrances. Scan everything: the Cyclops, Prawn Suit, modification station, and more are found in wrecks. Check every corner – some fragments are hidden inside cabinets or under debris.

9. Understand the story through radio and PDA logs

The game's narrative unfolds through radio messages and PDA entries left by previous explorers. Always check your radio after receiving a transmission. Explore the Aurora (after the radiation has dissipated) to find key story items. Follow the Degasi habitats and the alien bases to understand the planet's history. This not only advances the plot but often leads to essential upgrades.

10. Prepare for deep dives and the endgame

As you delve deeper, you'll encounter pressure limits, stronger creatures, and scarce resources. Upgrade your vehicles to maximum depth via the Modification Station. Carry a Prawn Suit with a drill arm for mining large deposits. Stock up on food, water, medkits, and batteries. Build a Cyclops as a mobile base to explore the Lost River and Lava Zones. Remember: always save before venturing into unknown depths.

Conclusion

Subnautica is a game about exploration, survival, and discovery. With these tips, you'll turn from a stranded survivor into a master of the deep. Keep calm, stay curious, and respect the ocean. Good luck, and may your seamoth never be eaten.
