Plan the opening hours around breathable air, hydration and reliable equipment.
Understand the mechanic
Subnautica starts with a small survival loop: gather accessible materials, craft essential equipment and return to air before a dive becomes dangerous. Staying near familiar shallow areas is often better than rushing toward an intriguing distant signal.
Put it into practice
Use short exploratory dives and bring materials back for crafting. Keep track of the escape route to the surface, especially when entering caves where a straight ascent is not possible. Watch hydration alongside food; both affect how long an expedition remains safe.
- 01Check water and food
- 02Plan a reachable air source
- 03Gather only needed materials
- 04Return before oxygen is critical
Common mistake to avoid
Large creatures and deep water are not the only threats. Misjudging oxygen in a narrow cave can be dangerous even very close to the starting location.
