DNA Modification Guide

Scan creatures, collect DNA, and unlock genetic abilities to enhance survival.

DNA Modification is a new core mechanic in Subnautica 2.

How It Works

  1. Scan creatures to collect DNA data
  2. Unlock genes from genetic data
  3. Equip modifications for passive or active abilities

DNA Sources

  • Small fish: speed boost, oxygen efficiency (common)
  • Medium predators: strength, resistance (uncommon)
  • Leviathans: powerful defensive traits (rare)

Priority Genes

Scan these first: Peeper (oxygen), Gasopod (toxic resistance), Boomerang (speed), Stalker (night vision).
