What We Know

The Ariadne Arm: everything confirmed so far

Every detail about the Subnautica 2 world, compiled from official Unknown Worlds dev vlogs, blog posts, and the Voices from Beyond story podcast.

Region

Ariadne Arm

A new region of space, light-years from 4546B. Unknown Worlds has confirmed Subnautica 2 is not a return to the original planet from Subnautica 1.

World Type

Alien Ocean Planet

An unnamed alien ocean world with fully open sea biomes. New flora, reef fish, and behavior-tree-driven predators shown across dev vlogs.

Apex Predator

Collector Leviathan

The first named Subnautica 2 leviathan, revealed in the September 2025 Creating the Collector dev vlog. More apex creatures teased for Early Access.

Primary Vehicle

Tadpole Submersible

The Tadpole is a one-to-two-seat sub shown in the December 2025 Crafting the Tadpole vlog. Modular loadouts, co-op passenger seat, upgraded depth modules.

Base Building

Modular Habitats

Confirmed in the March 2026 Building Bases vlog: deeper customisation, power routing, larger footprints, decorating, and shared co-op base progression.

Multiplayer

Four-Player Co-op

Up to four divers drop in and out of the same ocean, sharing base resources and progression. Diving Together vlog (February 2026) confirmed player-hosted sessions.

Engine

Unreal Engine 5

Subnautica 2 ships on UE5, a generational leap from Subnautica 1's Unity renderer. Expect Lumen lighting, Nanite geometry, and denser biomes at launch.

Publisher

Krafton & Unknown Worlds

Unknown Worlds was acquired by Krafton in 2021. Subnautica 2 is the first full-scale sequel under the new ownership, co-published by Krafton.

Interactive Map

What the Subnautica 2 map will ship with

Every feature below goes live the day Subnautica 2 enters Early Access, built on the same Leaflet-based system powering our Subnautica 1 and ARK: Survival Ascended maps.

Feature 01

Biome Overlays

Toggleable colour-coded regions for every confirmed biome as soon as Early Access drops. Kelp, reef, trench, and open-ocean layers stack independently.

Feature 02

Leviathan Danger Zones

Heat-mapped roaming territory for every named leviathan, starting with the Collector. We update zones as footage and patch notes confirm behavior.

Feature 03

POI Markers

Wrecks, crash sites, caves, thermal vents, alien structures, and lifepods, all with screenshots, loot lists, and scan-time estimates.

Feature 04

Depth Contours

Contour rings every 100 m so you can plan oxygen loadouts and Tadpole depth-module upgrades before diving.

Feature 05

Resource Nodes

Pinpoint where every mineral, plant, and crafting resource spawns once the save file can be read. Filter by resource type, depth, and biome.

Feature 06

Co-op Waypoints

Shareable URLs for waypoints so your crew loads the exact marker you pinned, whether they're joining your session tonight or a week later.

Map FAQ

Subnautica 2 map questions answered

Quick answers to what players keep asking about the Subnautica 2 world map.

Will there be an interactive Subnautica 2 map at launch?

Yes. Wikily's interactive Subnautica 2 map goes live the day Early Access opens in 2026. It ships with biome overlays, leviathan danger zones, POI markers, depth contours, and resource-node pins, built on Leaflet with marker clustering, the same engine powering our Subnautica 1 and ARK: Survival Ascended maps.

Is Subnautica 2 set on the same planet as Subnautica 1?

No. Unknown Worlds has publicly confirmed Subnautica 2 takes place in the Ariadne Arm, a new region of space light-years from planet 4546B. It is a different alien ocean world with its own biomes, creatures, and story arc.

How big is the Subnautica 2 map?

Unknown Worlds has not published an exact size. Dev vlogs have teased a world scaled to accommodate four-player co-op exploration without players constantly colliding, which implies a larger playable area than Subnautica 1's roughly 2 km square. Exact numbers will be confirmed at Early Access launch.

What biomes are confirmed for Subnautica 2?

Official footage has shown open-ocean surface waters, a reef biome, kelp-like growth, and deeper trench zones hosting the Collector Leviathan. The full biome list ships with Early Access; Unknown Worlds has explicitly said more regions will be revealed closer to launch.

When does the Subnautica 2 map launch?

Our interactive map launches the same day Subnautica 2 enters Early Access in 2026. Unknown Worlds confirmed the 2026 window alongside the July 2025 Take a Deep Breath gameplay reveal, after initially targeting 2025. No firm day or month has been announced.

Can I pin co-op waypoints on the Subnautica 2 map?

Yes. The map will support shareable waypoint URLs so your Subnautica 2 crew can load the exact marker you pinned, whether they drop in tonight or next week. This is the same system used on our ARK: Survival Ascended and Subnautica 1 maps.
