Subnautica 2 Black Box Signals Route

A spoiler-light signal route that keeps terminals, reported black-box objectives and return paths grouped by confidence.

Goal

Track early story signal checks without pretending every report is site-verified.

1. Start from shallow tools and oxygen
Route note
Treat the first signal sweep as a second outing: scanner, repair path, battery materials and a safe return line come first.
Third-party research materials
2. Check terminal and signal markers by region
Approximate
Use the Tech & Story filter to separate terminals, databank-style markers and loot containers from general landmarks.
Third-party research materials
3. Mark unknown black-box steps as route-only
Route note
If a step lacks a verified coordinate, keep it on the route checklist and do not treat it as an exact map point.

4. Return through known cave entrances
Approximate
Use cave and depth filters before committing to a deeper scan so the route does not strand you below your oxygen comfort zone.

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.
