Plan your next Subnautica session

Our independent guide helps you master Subnautica’s underwater challenges without relying on hidden tricks. By focusing on core mechanics—exploration, crafting, base building, creature interaction, and suit upgrades—you’ll develop a balanced approach that keeps you alive and curious as you uncover the planet’s secrets.

01 / THE GUIDE

Map the Biomes

Spend a session charting each biome’s visual cues and resource types. Compare shallow reefs to deep trenches, noting where oxygen consumption spikes and which creatures appear.

  • Plan routes that keep oxygen reserves high; surface briefly to refill if needed.
  • Visit night‑time areas for unique visuals, but stay alert for increased predator activity.

02 / THE GUIDE

Resource Prioritization Drill

Create a list of essential early‑game items and the resources needed for each. Test the list by gathering only those materials in a timed run, refining your efficiency.

  • Prioritize basic tools like a scanner and oxygen tank before venturing deep.
  • Collect a variety of resources early to unlock advanced crafting recipes.

03 / THE GUIDE

Base Layout Experiment

Construct two small bases at different depths, swapping module placements. Observe how hull‑integrity changes and which layout best supports oxygen replenishment.

  • Start with a small, shallow base to learn placement before building deeper structures.
  • Monitor hull integrity after adding new modules to avoid pressure failures.

04 / THE GUIDE

Predator Evasion Practice

Select a common predator and practice luring it with a fish versus outrunning it. Record which method conserves more oxygen and reduces damage.

  • Carry a fresh fish to distract aggressive fauna when needed.
  • Avoid open water at night unless equipped with adequate lighting.

05 / THE GUIDE

Suit Upgrade Comparison

Equip the PRAWN Suit with a drill, then with a propulsion cannon, and note differences in mining speed and travel distance. Use findings to decide upgrade order.

  • Upgrade the suit with a drill before attempting deep‑sea mining.
  • Add propulsion enhancements to reduce travel time between distant sites.
