How to Get the Heat Tolerance Trait in Subnautica 2

A Subnautica 2 guide shows how to unlock the Heat Tolerance trait in a cave east of the Lifepod.

Use the Sonic Resonator to clear Bloom Biofilm, reveal the Gene Donor, and activate it to gain the trait.

Heat Tolerance lets players explore hot zones for key resources like sulfur and gold, but some areas still require extra oxygen gear.

The trait is important for deeper progression because it opens access to dangerous areas with valuable creatures and plants.
