Alien Ruins are not just another landmark. The route usually asks for more range, better oxygen planning, and a clear retreat path before you cross open water or deeper corridors.

Quick Answer
Use this page as a route checklist: identify the target, check whether your oxygen and tools match the depth, then open the map before leaving base.
Before You Leave
- Confirm the resource, scan target, or repair objective before swimming out.
- Bring enough oxygen support or vehicle range for the return.
- Mark a recognizable landmark before entering deeper terrain.
- Check whether the route can be combined with another material or upgrade.
Why It Matters
This topic usually matters because it blocks the next useful step: crafting, scanning, safer travel, or a deeper objective. A planned route saves more time than a blind search.
Map Route
Open the world map for depth and nearby biomes. If this is a material run, compare it with the resources guide so you can group several pickups into one trip.
Early Access Note
Subnautica 2 is still in Early Access, so routes, recipes, callouts, and scan requirements can change after patches. Recheck the in-game recipe or objective before farming extra.
