Biomods Overview
The checklist is located below this introductory text.
Biomods are late-game upgrades you equip directly on your character. Build the Biolab facility to unlock biomods. Active biomods can be triggered at will; passive biomods are always on.
Some biomods are unlocked by default, while others need scans of specific creatures or flora.
