Subnautica Codexery — Data & Quality

We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.

This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.

Last full accuracy audit: 2026-08-23 · 30 entries checked · 17 flagged · 45 issues confirmed · 17 corrected · 28 still open

Recent findings (audit lane, verbatim)

The Survivor — The Neptune Launch Platform is constructed by the player at a location of their choosing, not canonically on the Floating Island.

The Survivor — Marguerit Maida is the only Degasi crew member who survived long-term, but all three members died on 4546B; the statement that the Degasi crew survived before the player is incorrect.

Sea Emperor Leviathan — The Sea Emperor Leviathan is not located in the Lava Lakes; it is encountered inside the Primary Containment Facility, which is a separate biome from the Lava Lakes.

Sea Emperor Leviathan — The Sea Emperor does not die specifically from the effort of laying eggs and long captivity; it dies from old age and exhaustion after its offspring hatch.

Crab Spiders — Crab Spiders are not found in the Jellyshroom Caves; they are found in the Deep Grand Reef, Lost River, and Inactive Lava Zone biomes.

The Virus — The entry states the Kharaa Bacterium was 'originally released on Planet 4546B by the Precursors during their research, long before the Aurora's crash.' This is incorrect: the Kharaa Bacterium was a native pathogen the Precursors were studying, and its release

The Virus — The entry states 'Reefback Leviathans can be infected by the Kharaa Bacterium and show visible green pustules or tumors as a result.' This is inaccurate: Reefback Leviathans are not shown to be infected by the Kharaa Bacterium in the game; the green pustules/t

Reef Leapers — The entry is about 'Reef Leapers' but describes 'Reefbacks', which are a different creature; Reef Leapers are hostile and found in Kelp Forests, not passive giants.

Containment Facility — The Containment Facility is located in the Lava Lakes, not the Inactive Lava Zone; the Sea Dragon Leviathan is encountered in both the Inactive Lava Zone and Lava Lakes, but the facility itself is only in the Lava Lakes.

Containment Facility — The Sea Dragon Leviathan is not stated in canon lore to have 'escaped' from the Containment Facility; the game implies it may have been released or the facility was abandoned, but there is no confirmed lore that it escaped before the player's arrival.

Memory Cores — The entry states the Kharaa virus was an accidental outbreak from their research, not a failed weapon or cure attempt, but canon shows the Precursors were deliberately trying to create a cure for a pre-existing Kharaa infection.

Memory Cores — The entry says the Precursors' extinction was directly caused by the virus itself, but canon indicates they left the planet and did not go extinct on 4546B.

Alien Signal — The entry states the signal is 'explicitly described as a distress beacon that lures ships, as shown by the Degasi and Sunbeam.' In canon, the Degasi was not lured by the signal; it crashed due to a storm, and the Sunbeam was lured by the distress signal from

Alien Signal — The entry claims the signal is 'part of an automated system designed to destroy incoming ships' and that the Quarantine Enforcement Platform was designed to destroy ships to prevent the plague from leaving. In canon, the Quarantine Enforcement Platform shoots
