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
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?
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.
