Flash Slug
HarvestOrganicOverview
Flash Slug is an organic material in Subnautica 2, obtained by harvesting from the environment. Used as a crafting ingredient in Isotonic Water, requiring 1 per craft at the Fabricator. This positions Flash Slug in the equipment progression, where crafted tools and gear expand the player's exploration range, survivability, and resource-gathering efficiency. Unlike minerals, organic materials like Flash Slug are renewable but location-dependent. The organisms that produce them inhabit specific biomes at particular depth ranges, making exploration knowledge your primary tool for establishing consistent supply lines.
