Subnautica: Below Zero

Subnautica: Below Zero is a first-person underwater survival adventure. You play as biologist Robin, traveling alone to the Arctic to uncover the truth behind her sister Sam’s death. In this harsh, icy world, survival depends on how well you manage your needs: collect resources, construct a base, craft gear for extreme cold, and travel through unfamiliar waters to reveal what Altera Corporation was secretly researching—work tied to the Kara virus and its potential use as a biological weapon. In the end, your mission is to honor Sam’s last request and stop the viral threat.

Survival Tips

1) Focus on Dependable Power

Your base will only produce oxygen when it has power, so energy needs to be your first priority.

• Early game: Use solar panels in shallow areas.



• Mid to late game: Upgrade to bioreactors, thermal plants, or a nuclear reactor for steadier output.
• Don’t bet everything on one source: Combine systems to stay stable.
• Power equals functionality: A well-powered base keeps oxygen, lighting, and equipment working properly.

2) Pick Base Locations Carefully

Your base placement affects efficiency. The best areas typically provide:

• Quick access to multiple biomes
• Plenty of resources nearby
• Relatively safer surroundings with fewer aggressive creatures

Choosing a central or mid-depth area often reduces travel time and makes long-term resource gathering easier.

3) Protect Hull Integrity Early

As your base expands, its structure can weaken. If you don’t manage integrity, you may get flooding.

• Reinforce or add foundations regularly
• Avoid stacking too many glass modules too early
• Use bulkheads to contain damage if water starts spreading

Keeping the base structurally sound helps you avoid sudden, unwanted disasters.

4) Reduce Energy Waste

Many base devices consume power, including fabricators and charging stations.

• Turn off or limit power-hungry tools like water filtration
• Build only what you actually need early on
• Increase power generation as your base grows

If your energy management is efficient, your base is less likely to lose oxygen production or stop critical functions.

5) Build in Stages, Not Everything at Once

Instead of building a huge facility immediately, grow it step-by-step:

• Start with a basic room plus a power source
• Add storage and a crafting area
• Then expand with advanced modules like a scanner room and a vehicle dock

This approach saves resources and keeps your base manageable as you progress.

6) Plan Layout for Faster Gameplay

A smart interior design improves flow and saves time:

• Place storage near crafting stations
• Keep vehicle docks close to entrances
• Separate living spaces from utility rooms

Efficient layouts reduce unnecessary walking and speed up daily tasks.

7) Match Your Base to the Environment

Different regions call for different strategies:

• Shallow areas: solar power tends to work best
• Deep or volcanic zones: thermal energy is often more effective
• Cold surface zones: build nearby warmth shelters

Adapting your base design to local conditions improves survival efficiency.
