Hotfix 1 quick summary
Subnautica 2 Hotfix 1 is the first Early Access stability checkpoint after the May 14, 2026 launch. Use this page as a patch-aware checklist: confirm startup stability, co-op base behavior, graphics-driver issues, and any recipe or route changes before trusting older guide notes.
| Date | Update | What to check |
|---|---|---|
| May 14, 2026 | Early Access launch | Crossplay, first world setup, shared co-op saves, starter routes. |
| May 15, 2026 | Roadmap window | EA 1.1 and EA 1.2 priorities, quality-of-life work, co-op improvements. |
| May 19-20, 2026 | Hotfix 1 coverage | Startup crashes, AMD/DX12 reports, co-op building issues, guide pages affected by fixes. |
What players should do after updating
Restart the game, verify the build, then test the exact problem that blocked you before. For crashes, check graphics drivers and launch options first. For co-op construction, test one wall, window, or deconstruction action in a safe base before editing an important structure. For route or recipe changes, open the in-game interface before spending rare materials.
Guide pages to recheck
Revisit known bugs and fixes, crashing on startup, cannot deconstruct bug, Early Access roadmap, and Interactive Map and All Locations.
Update policy
This site should update patch pages first, then affected guides. Any guide that mentions crashes, co-op building, route safety, recipes, modules, or tool behavior should include the latest patch date when the behavior changes.
