Subnautica 2 Water Slug Guide

Where to find Water Slug in Subnautica 2, how to scan it safely, what it means for routes, and what risks to avoid.

Water Slug quick answer

Water Slug is a utility fauna entry most worth checking around Shallows. Scan it only when you still have a visible route home, enough oxygen to retreat, and a clear reason to add the creature to your current checklist.

Location and route

Start from the closest safe landmark in Shallows, then make one pass to identify sightlines before committing to the scan. If the creature pulls you away from the marked route, cancel the attempt and return with more oxygen, better mobility, or a vehicle-supported path.

Uses and unlock value

Water Slug is mainly useful for drinking water route and creature log. Record the biome, nearby plants, nearby minerals, and the tool loadout that made the scan safe; those notes are more valuable than a one-time sighting during Early Access.

Risk and scan notes

One of the most useful starter-route checks. The safest scan window is after you stop moving, check oxygen, and confirm no larger threat is closing from behind. In co-op, one player should hold the landmark while another scans so the team does not lose the return line.
