Subnautica 2 Tadpole Pens Route

A cautious route for the Tadpole Pens area: gather bearings, check cave entrances, and separate route-only notes from exact markers.

Goal

Give players a cave-aware route frame for Tadpole Pens exploration without inventing exact pins.

1. Approach through known landmarks
Route note
Use nearby named regions and cave entrances as anchors, then keep unverified pen notes as route-only checklist items.
Third-party research materials
2. Toggle caves before committing
Approximate
The Caves tab should be checked independently from general landmarks so entrances and deep-cave reports stay visible.

3. Leave a clean return path
Biome-only
Do not chain multiple deep checks unless the map still shows a known exit and you have enough oxygen to backtrack.

Does this route draw an exact line on the map?

No. The route uses waypoint cards and approximate areas because the current evidence is not enough for a verified line.

What should I do after this route?

Open the Quartz and Silver guides, then submit any launch-build screenshots or video if you can verify exact coordinates.
