Research summary
Official Subnautica 2 sources confirm a survival-crafting loop built around gathering resources, crafting tools, designing custom bases, scanning lifeforms, using submersibles, and upgrading tools, equipment, and vehicles through Early Access. The strongest current official details are that Early Access includes a variety of craftables, several biomes, the Tadpole submersible, an all-new/procedural base-building system, customizable bases, basic tools such as the Scanner and Flashlight, recipes for more advanced tools, equipment, and submersibles, and ongoing additions of more craftables, features, vehicle upgrades, tools, biomes, creatures, and narrative. Exact resource names, crafting recipes, base module stats, Tadpole recipe, chassis list, depth limits, vehicle upgrade tree, and launch-day item database remain [uncertain] until verified from the live Early Access build or official patch notes.

Unconfirmed or changing details
Use Unknown Worlds, Subnautica.com, official storefronts, official patch notes, and the official wiki as primary sources. Use in-game verification from the live Early Access build as high-confidence implementation data when official written pages are incomplete. Mark fan wiki claims, Reddit reports, YouTube frame analysis, leaked builds, datamines, inferred Subnautica 1/BZ carryovers, and unverified competitor item lists with [uncertain]. Do not mix confirmed recipes with speculative recipes in calculator totals unless the user explicitly enables unverified data.
- [uncertain] A complete official resource list was not found in public official pages checked for this research.
- [uncertain] Exact material names, biome spawn locations, harvest nodes, and resource rarity tiers must be verified from the live Early Access build or official wiki updates.
- [uncertain] Exact crafting recipes, raw-material totals, fragment requirements, station requirements, and unlock order are not confirmed by current official public pages.
- [uncertain] Exact launch-day tools and equipment beyond officially named examples such as Scanner and Flashlight are not fully confirmed.
- [uncertain] Tadpole recipe, crush depth, health, storage capacity, power-cell behavior, upgrade slots, chassis variants, passenger count, and module names require launch-build verification.
- [uncertain] Fan pages report specific Tadpole details such as a Vehicle Fabricator source, Power Cell, upgrade slots, storage, chassis attachments, and ride-along handles, but those should remain secondary until verified against the game or official wiki.
