5 Subnautica 2 pages in Story.

• CharactersSubnautica 2's characters are your silent Pioneer (six playable looks since update 1.2 added Jegna and Grace), NOA, the Cicada's Noetic Advisor AI, a second AI voice, and the vanished colonists heard only in blackbox recordings, such as Anita, Chap, Wander, Ruby, Quaker, Sophie, Nahema, Wu, Singh and Zip.
• Story and LoreIn Subnautica 2 you are a Pioneer on Alterra's colony ship Cicada, carrying 40,000 people away from a war-torn home, when something goes wrong and you wake on an alien ocean world where an earlier wave of colonists has vanished. The story is unfinished in Early Access as of Nov 4, 2026; its next chapter comes with Early Access 2 in December 2026.
• The AxumThe Axum are the alien civilization of Subnautica 2, known only by what they left: ruins, an Observatory tower, a Power Plant, Metal Farms, Gateway Spires and the Rosetta Stone that makes their logograms readable once you gain the Axum Vision Adaptation. Early Access 2 in December 2026 expands their history.
• The BloomThe Bloom is Subnautica 2's infection: biofilm, sap, cankers and parasites that block caves, infect creatures and Angel Combs, and cannot be cleared by hand. You get past it with the Sonic Resonator, and the armored pink cankers need the Feedback Resonator; some places and guides call it the Blight.
• Voices from BeyondVoices from Beyond is Subnautica 2's five-episode audio drama, released by Unknown Worlds from Nov 25, 2025 to Mar 26, 2026, about a young family in a Mongolian settlement as a threat closes in, ending with a distress call from the Cicada.
