  "textContent": "Subnautica 2 drops you onto an entirely new alien ocean world, not the planet 4546B from the original game or the icy setting of Below Zero. The sequel was built around a fresh planet with its own ecology, creatures, and ruins, designed so newcomers can start here without needing any prior context from the franchise.\n\n🌊\n\nQuick answer: Subnautica 2 is set on a brand-new alien ocean planet — a different world from 4546B — that was previously the site of a failed human colony delivered by the colony ship CICADA.\n\nImage credit: __Unknown Worlds Entertainment__\n\n* * *\n\n### The new planet, not 4546B\n\nUnknown Worlds made a deliberate call early in development to leave the original planet behind. Instead of revisiting the Aurora's crash site or the frozen biomes of Below Zero, the team built a new world from scratch, with new biomes, new lifeforms, and a separate story arc.\n\nLead game designer Anthony Galagos has described the design target as roughly a third new content, a third familiar Subnautica DNA, and a third improved systems. The new planet is the foundation of that \"third new\" — it shares the underwater survival identity of the series but does not reuse locations, creatures, or factions from earlier games.\n\nNone of the named regions from Subnautica or Below Zero appear here. The Safe Shallows, the Lost River, Sector Zero — none of them carry over. What you get instead is an unfamiliar ocean with its own silhouette of biomes to memorize.\n\nImage credit: __Unknown Worlds Entertainment__\n\n* * *\n\n### The CICADA, the Pioneers, and how you got here\n\nThe setup frames why you are stranded on this specific planet. Alterra, the corporation present throughout the franchise, offers a fresh start to people displaced by ongoing conflict. You join a group called the Pioneers aboard a colony ship named CICADA, headed for this new world.\n\nSomething goes wrong during the mission. The ship's AI insists the colonization must continue even as things fall apart, and you wake up on the planet with no memory of how you arrived. The colony that was supposed to be waiting is gone — the colonists have already failed, died, or vanished — and you are left to piece together what happened.\n\nThat backstory is what shapes the world you explore. Wrecks from the CICADA, abandoned habitats, and alien ruins are scattered across the seabed, each tied to the failed colonization effort.\n\nImage credit: __Unknown Worlds Entertainment__\n\n* * *\n\n### How the world is structured: regions and biomes\n\nSubnautica 2 adds a structural layer above biomes called regions. A region is a large continuous area that holds multiple themed biomes and sub-biomes inside it. You move between biomes within a region with relatively smooth transitions, then cross a deliberate boundary to enter a different region with its own visual identity and survival profile.\n\nAt Early Access launch, at least two main regions are in the game, with more planned to roll out during the Early Access period. Biomes inside those regions include kelp-style growth, coral gardens, thermal vent caves with extreme temperatures, alien ruins, and deeper trench environments.\n\n🗺️\n\nNote: There is no in-game map by design. Unknown Worlds wants you to navigate using the on-screen compass, landmarks, beacons, and the PDA scanner — the same philosophy used in Subnautica and Below Zero.\n\n* * *\n\n### Key locations across the planet\n\nSeveral landmarks tie directly to the story and progression. Most early exploration radiates outward from your Lifepod, with deeper and more dangerous sites pushing east, north, and into the depths below.\n\nLocation| What it is\n---|---\nLifepod| Your starting point and the reference for all directional distances early on.\nCamp One| An early colonist site north-northeast of the Lifepod, accessed through an underground tube.\nOld Habitat| A flooded colonist structure north of the Lifepod containing multiple Blackboxes and key story scans.\nColonist Bunker (Quaker's Meetinghouse)| A southeast crag hiding a hatch, biobed, and early inventory upgrade.\nHeat-emitting coral caves| An underwater cave cluster east-southeast with extreme temperatures, requiring the Heat Tolerance Adaptation.\nSpider Dome| A south-southwest landmark with a hole beneath it; needs a Sonic Resonator to clear the bloom.\nAlien Ruins| A mid-to-late game zone east of the Lifepod, gating deeper story content.\nCICADA Wrecks| Pieces of the colony ship scattered across the planet, including the EVA Prep and Therapy Room sections.\nMetal Farms| A late-game seabed area roughly 2 km east of the Lifepod, past the Alien Ruins.\nNeedler Nest| A mid-to-late game cave cluster with hostile Needlers.\nImage credit: __Unknown Worlds Entertainment__\n\n* * *\n\n### The ecology of the planet\n\nThe world has its own biology that you cannot simply consume on arrival. You start unable to digest the local proteins, which means eating native flora or fauna requires acquiring a Digestion Adaptation by interacting with specific plant life — the Angel Comb Jelly being the first one most players encounter near the Lifepod.\n\nThe planet is also affected by an ecological system called the Blight. When the world is in distress, infections spread through root systems and turn local creatures aggressive in a zombie-like state. Muted colors signal infected areas, and clearing infestations is part of how you stabilize zones.\n\nFive Leviathans are present at Early Access launch, including the Collector — the large, aggressive predator most players will want to avoid. A giant coral crab also appears in the deeper biomes. There are no weapons in Subnautica 2, so handling these creatures relies on tools like the Sonic Resonator, Distraction Flares, and stealth.\n\n* * *\n\n### NOA, the silent protagonist, and isolation\n\nYou play a silent protagonist this time around, a deliberate change after Below Zero's voiced lead drew criticism. Your only consistent companion is NOA, an AI you have to physically visit at a terminal to interact with. NOA cannot speak to you while you are out in the field, which keeps the sense of isolation intact even though the planet has a heavy human history.\n\nNOA also drives the story forward through Blackboxes — flight recorder capsules left behind by the CICADA colonists. Each Blackbox triggers a postmortem playback of how that specific colonist died and unlocks new signals that point you toward the next location. There are 24 Blackboxes in the current Early Access build.\n\nImage credit: __Unknown Worlds Entertainment__\n\n* * *\n\n### A self-contained story\n\nYou do not need to have played the earlier games to follow what is happening. The story is built to be fully self-contained, with callbacks for franchise veterans but no required background. Alterra is still in the picture as the corporate force behind the colony, which connects the sequel to the wider Subnautica universe, but the planet, the colonists, and the central mystery are all new.\n\nFor players who want extra lore, Unknown Worlds released an optional audio drama called _Voices from Beyond_ on its official YouTube channel that fills in context leading into the events of the sequel.\n\n* * *\n\nThe short version: forget 4546B. Subnautica 2 takes place on a new alien ocean world tied to the collapse of the CICADA colony, structured into multiple regions of biomes you navigate by landmark and compass rather than a built-in map. Early Access covers the first chapter of the story, with more regions, creatures, and content scheduled to land across the next two to three years of development.",
