Tips：

Prioritize Reliable Power Sources

Your base will only generate oxygen when it has power, making energy your top priority.

Early game: Use solar panels in shallow areas

Mid/late game: Switch to bioreactors, thermal plants, or nuclear reactors for consistent energy

Avoid relying on a single power source—combine systems for stability

A well-powered base ensures oxygen, lighting, and all equipment function properly.

Choose Strategic Base Locations

Location determines how efficient your base will be. The best spots usually offer:

Easy access to multiple biomes

Abundant nearby resources

Safe surroundings with fewer aggressive creatures

Central or mid-depth areas help reduce travel time and make resource gathering more efficient over time.

Maintain Hull Integrity Early

As your base grows, its structural integrity decreases, which can cause flooding if not managed.

Add reinforcements or foundations regularly

Avoid excessive glass modules early on

Use bulkheads to isolate damage if flooding occurs

Keeping your base structurally stable prevents unexpected disasters.

Optimize Energy Consumption

Every device inside your base consumes power, including fabricators and charging stations.

Turn off or limit high-drain equipment like water filtration systems

Build only what you need early on

Expand energy production as your base grows

Efficient energy use ensures your base doesn’t suddenly lose oxygen or functionality.

Build in Phases, Not All at Once

Instead of creating a massive base immediately, start small and expand gradually:

Basic room + power source

Storage and crafting area

Advanced modules (scanner room, vehicle dock)

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

Plan Layout for Efficiency

A well-organized layout saves time and improves gameplay flow:

Keep storage near crafting stations

Place vehicle docks close to entrances

Separate living areas from utility rooms

Efficient layouts reduce unnecessary movement and make daily tasks faster.

Adapt Your Base to the Environment

Different regions require different strategies:

Shallow areas → solar power works best

Deep or volcanic zones → thermal energy is more effective

Cold surface zones → build shelters for warmth nearby

Adapting your base design to the environment increases survival efficiency.
