Plan your next Subnautica: Below Zero session

Our independent guide breaks down Below Zero’s core systems, offering observations that help newcomers and veterans make informed choices without relying on hidden mechanics or paid upgrades.

01 / THE GUIDE

Habitat Placement Evaluation

Compare building a habitat near a Thermal Vent versus in open tundra. Note how proximity to heat reduces the need for additional warming gear, while open sites may provide easier access to surface resources.

  • Read every log and databank you find; they often contain essential story details.
  • Note environmental cues like weather changes that may indicate hidden locations.

02 / THE GUIDE

Vehicle Role Comparison

Observe the Snowfox on flat tundra and the Seatruck in a shallow bay. Record how each handles obstacles and the type of cargo you can carry without assuming any hidden upgrades.

  • Use natural lighting to spot points of interest from a distance.
  • Watch your depth gauge when diving into deeper zones.

03 / THE GUIDE

Cold Suit and Heat Source Balance

Test staying near Thermal Lilies versus relying solely on a cold suit. Track how quickly your temperature drops in each scenario to decide how many heat sources to carry.

  • Prioritize habitat insulation before venturing far from base.
  • Construct a Snowfox early to reach distant surface points quickly.

04 / THE GUIDE

Biome Resource Mapping

Create a simple map marking where key materials appear in each biome. Cross‑reference with crafting recipes to prioritize which areas to explore first.

  • Monitor your temperature meter regularly, especially when outside habitats.
  • Carry a backup heat source in case weather changes unexpectedly.

05 / THE GUIDE

Creature Behavior Observation

Watch friendly fauna like Pengwings and hostile ones like the Shadow Leviathan. Note distances at which they become aggressive to plan safe navigation routes.

  • Enable Steam Cloud to protect progress across multiple devices.
  • Test controller settings early to ensure comfortable control schemes.
