Subnautica: 10 Pro Tips for Exploring the Depths and Surviving the Ocean
Introduction

Subnautica drops you into an endless ocean with nothing but your wits and a lifepod. Survival requires careful exploration, resource gathering, and a healthy dose of caution. These 10 pro tips will help you thrive in the depths of Planet 4546B.
1. Prioritize the Seamoth Early
The Seamoth is your first major vehicle and a game-changer. Craft it as soon as you scan its fragments. It provides speed, storage, and oxygen, making deep dives far safer. Upgrade it with a depth module to reach the Kelp Forest and beyond.
2. Build a Scanner Room
Scout locations with a Scanner Room. It highlights resources, fragments, and creatures in its range. Place it near your base and upgrade with range extenders. Use its camera drones to explore dangerous areas without risking your life.
3. Master the Stasis Rifle
The Stasis Rifle is your best defense against aggressive fauna like Stalkers and Reaper Leviathans. Charge it to freeze enemies in place, giving you time to escape or scan. Keep it in your quickbar at all times.
4. Start Your Base in the Safe Shallows
Build your first base in the Safe Shallows. It’s close to basic resources like titanium, copper, and quartz, and relatively predator-free. Later, expand to the Grassy Plateaus for more space and access to deeper biomes.
5. Manage Your Oxygen Efficiently
Always carry extra oxygen tanks. Craft a high-capacity tank as soon as possible. Use a seaglide for speed, but remember it drains oxygen if you sprint. Plan dives around air sources: use creepvines, brain corals, and your vehicles as oxygen refill points.
6. Scan Everything
Scan all fragments and creatures you encounter. Fragments unlock blueprints for tools, vehicles, and base modules. Creature scans provide valuable databank entries and sometimes reveal weaknesses. Use the scanner room to locate fragments faster.
7. Use Beacons for Navigation
Drop beacons at key locations: your base, cave entrances, resource hotspots, and dangerous zones. They appear on your HUD, making navigation easy. Color-code them: green for safe, red for danger, blue for points of interest.
8. Prepare for Deep Dives
When venturing into deeper biomes like the Lost River or Lava Zones, bring extra power cells, a repair tool, and spare food. Use the Cyclops as a mobile base. Upgrade your depth modules to withstand pressure. Always have an emergency plan to surface.
9. Avoid the Reaper Leviathan
The Reaper Leviathan patrols the Aurora’s bow and stern. Avoid these areas unless necessary. If attacked, use the Seamoth’s perimeter defense system (if upgraded) or the Stasis Rifle to escape. Never stop moving in its territory.
10. Save Often and Use Multiple Saves
Subnautica autosaves only when you enter a base or vehicle. Manual save frequently, especially before risky expeditions. Use multiple save slots to revert if something goes wrong, like losing your Cyclops to a leviathan.
Conclusion
With these tips, you’ll explore the depths more safely and efficiently. Remember: the ocean is beautiful but deadly. Respect it, prepare thoroughly, and you’ll uncover the secrets of Planet 4546B.
