OVERVIEW

Understanding Survival Knife

An early tool for harvesting certain plants and protecting against small threats.

This is an original reference for the first Subnautica. Your current depth rating, oxygen, available tools and navigation route determine when an objective is practical. Follow actual in-game PDA and Fabricator information for any values that vary by version.

PRACTICAL APPROACH

How to use this information

Use it for plant samples and emergency parasite removal, not for hunting every predator.

COMMON MISTAKES
