Subnautica 2 Water Slugs Guide — How to Get Water

How to Get Water Slugs

Scan a Water Slug first to unlock crafting recipes

Water Slugs Location

Coral Reefs biome — most abundant near the Lifepod

Finding Water Slugs in the starting Coral Reefs biome is the fastest way to obtain water in the early game. Swim up to a Water Slug to add it to your inventory. Make sure you have enough open inventory slots before gathering.

The Bottom Line: Subnautica 2 respects your intelligence in a way most games don’t. It doesn’t put a glowing arrow on everything you need to interact with. It expects you to explore, experiment, and yes — die a few times. The guides on this site exist because I’ve already done the dying for you. Use them, learn the systems, and then go experience the terror and wonder of this alien ocean for yourself. There’s nothing else quite like it.
