Route Readiness Checker

Pick a route, choose your oxygen state, tick the gear you already have, and get a quick go / caution / prepare-first answer before leaving base.

Checked June 8, 2026

Use it before the dive, not after the panic

This tool is built around the same P2-P10 video route series as the new guide batch. It does not pretend to be a perfect map coordinate system. It answers the practical question players ask at base: am I prepared enough to start this route?

Caution

You can probably start, but the missing recommendations make the return trip less forgiving.

Tool note

This checker uses route gates and safety suggestions from the current guide pages. Subnautica 2 is still in Early Access, so oxygen values, module gates, recipes, and route difficulty may change after patches.
