Subnautica 2 achievements — what we know so far
No confirmed achievement list exists at Early Access launch. Subnautica 2 went live on Steam and Xbox on May 14, 2026 without a published Steam achievements list or an Xbox gamerscore manifest. This page tracks what's known and will update as Unknown Worlds patches them in.
Current status (as of May 25, 2026)
- Steam achievements: Not yet published. The Steam store page does not list an achievements section.
- Xbox achievements / gamerscore: Not yet exposed. Game Preview titles sometimes ship without Xbox achievements; Unknown Worlds has not committed either way.
- In-game milestone tracking: The PDA tracks scans and major story beats, but those are progression milestones rather than platform achievements.
- Trophy list (PS5): N/A — Subnautica 2 is not on PS5. See PS5 page.
Why aren't they live yet?
Early Access games frequently ship without finalized achievement lists for two reasons. First, achievements are part of the platform-certification process — locking the list before content stabilizes risks orphaned or impossible achievements after later patches. Second, achievement design tends to follow story completeness, and Subnautica 2's story arc isn't complete at EA — major endgame achievements would spoil unreleased content.
Subnautica 1 added its full Steam achievement set after its 1.0 launch in 2018, not during its three-year EA window. Below Zero followed a similar pattern. The most likely outcome for Subnautica 2: a partial set during EA, the full list at 1.0.
What to expect (based on Subnautica 1)
Subnautica 1 shipped with ~17 Steam achievements at 1.0, mostly tied to milestone progression: first base, first vehicle, key scans, leviathan encounters, and the ending. A reasonable bet for Subnautica 2:
- Story milestones — first base built, first Tadpole crafted, first Sonic Resonator used, Power Plant restored, Observatory reached.
- Bestiary — scan a leviathan, scan all 5 EA leviathans, encounter the World Tree at the map edge.
- Co-op — host a session, join a friend, four-player full lobby — these are likely candidates for SN2 specifically because they didn't exist in SN1.
- Hidden / story — secret blackbox recoveries, deep biome firsts, NOA dialogue branches.
- Hard-mode / no-vehicle / pacifist challenges — SN1 had these as community challenges; SN2 may codify them.
None of the above is confirmed. Treat this section as expectation-setting based on Unknown Worlds' history, not as a leaked list.
How to track progress now
- PDA databank. The in-game PDA tracks scans, blueprints, and story logs — closest thing to an achievement tracker today.
- Codex. Use the wiki's codex to see which creatures, items, and modules you've encountered.
- Walkthrough tiers. Tier-by-tier progression maps to the likely future achievement structure.
- Manual save backups. If a future achievement requires a one-shot trigger (e.g., "complete game without dying"), having clean saves now helps.
For trophy hunters / completionists
If your Steam profile or Xbox gamerscore matters to you and you want to wait for the full list: play Subnautica 2 now on Game Pass to evaluate it, then plan a completion playthrough when achievements drop. Subnautica's progression unlocks are one-way for some scans and story beats, so a clean New Game save when the list is published is the safest path.
