Research summary
Subnautica 2 map and biome content should be built as a spoiler-safe, source-tiered navigation hub. Official sources confirm an all-new alien world, Early Access on May 14, 2026, multiple biomes at launch, future expansion with additional biomes, traversal by the Tadpole submersible, base building beyond shallow waters, and an exploration-first design that uses beacons/objectives and environmental discovery. Public official pages checked for this research do not provide a precise world map, coordinate atlas, final biome list, final map size, or final depth chart. Community and competitor pages report that Subnautica 2 has no built-in map and should be navigated with compass, landmarks, PDA scans, and beacons [uncertain]. Exact biome names, depth ranges, coordinates, map boundaries, region count, and interactive map marker locations should remain [uncertain] until verified from launch gameplay, official patch notes, or directly checked in-game data.
- Subnautica 2 is built around discovery on an all-new alien world.
- Early Access includes several biomes, with more biomes planned during development.
- Official sources do not currently provide a final world map, coordinates, exact map size, or complete depth table.
- Community reports say there is no in-game map and that players navigate with compass, landmarks, PDA scans, and beacons [uncertain].
- Use beacons for base entrances, cave mouths, resource loops, deep staging points, and co-op rendezvous points [uncertain].
- The Tadpole submersible is the officially named traversal vehicle for biome exploration.
Confirmed facts
Facts below are drawn from official or high-confidence sources and should be prioritized above community reports.

- Steam and official Unknown Worlds copy describe the game as Early Access and in active development.
- Official Steam copy says Subnautica 2 will include multiplayer, several biomes, some narrative, and a variety of creatures and craftables in the Early Access version.
- Official Steam copy says the full version is planned to have substantially more content than the Early Access version.
- Official sources say Early Access updates will expand the world with additional biomes, creatures, craftables, features, and narrative content.
- Unknown Worlds' 2025 delay update said the extra time would allow more biomes, more vehicle upgrades, additional tools, expanded story, and more creatures for Early Access.
- Official Steam copy says players traverse biomes with the Tadpole submersible.
Content modules to include
These modules translate the keyword research into page sections, tables, tools, and update surfaces.
- Short answer box: official sources confirm exploration-first biome discovery, but no public official coordinate map or final map size was found.
- Map availability section separating official public facts from community-reported no-map claims [uncertain].
- No-map navigation guide covering compass headings, recognizable landmarks, surface/base reference points, route notes, PDA scans, and beacon chains.
- Beacon strategy section for base entrances, cave mouths, resource loops, deep-dive staging points, co-op rendezvous points, and emergency return routes [uncertain].
- Spoiler-safe interactive map introduction with default hidden POIs, optional layers, and source-quality labels.
- Biome index split into official description, trailer-visible environment, community-reported name, depth band, danger level, and spoiler level.
- Shallow biomes page structure for first-session routes, oxygen-safe exploration, scanner priorities, and early base scouting [uncertain].
- Deep biomes page structure for pressure-depth preparation, currents, vehicle readiness, retreat beacons, and Leviathan-risk warnings [uncertain].
Unconfirmed or changing details
Official Unknown Worlds/Subnautica pages, Steam, official trailers, official dev vlogs, and patch notes are the highest-confidence sources. Direct release-build verification with screenshot/build metadata is next. Community maps, Discord summaries, Reddit claims, YouTube breakdowns, datamines, and file extraction are useful but must be labeled [uncertain] unless independently verified. Never expose story locations, late-game biome names, rare resources, or Leviathan territories in default spoiler-safe views. Do not use leaked unofficial builds as canonical evidence.
- [uncertain] Community and competitor pages report that Subnautica 2 ships without an in-game map, citing official Discord and the May 9, 2026 showcase, but a public official webpage with that exact statement was not found in the checked sources.
- [uncertain] Community and competitor pages report navigation by compass, landmarks, PDA scanner/databank, and player-placed beacons; this matches series design and developer discovery philosophy, but exact Subnautica 2 UI behavior needs in-game verification.
- [uncertain] Exact beacon recipe, beacon range, co-op beacon sharing behavior, and whether all players see all beacons should be verified after launch.
- [uncertain] Exact map size is not confirmed by official public sources checked here; claims that the Early Access map is bigger, half-size, two-region, or larger than previous Early Access launches should remain unconfirmed unless official or measured in-game.
- [uncertain] Exact biome names such as Sparse Plains, Graveyard, Thermal Spires, Plateaus, Kelp Forest, Twisty Bridges, trench, reef, or crash-zone-like labels appear on community and competitor pages, but should not be treated as final official page titles without direct confirmation.
- [uncertain] Exact shallow biome and deep biome depth bands are not confirmed by official public sources checked here.
