Frequently Asked Questions
The fastest answers to the questions Subnautica 2 players ask about the interactive map and navigating the Ariadne Arm.
What is the Subnautica 2 interactive map?
The Subnautica 2 interactive map is a browser-based exploration tool that lets you navigate the Ariadne Arm with source-tracked points of interest, biome boundaries, resource locations, black box positions and creature habitats. Each POI is tagged with its confidence level — confirmed from official footage, community-sighted, or predicted from franchise patterns — so you can plan dives with accurate information.
How many biomes are in Subnautica 2?
At Early Access launch, the Subnautica 2 map features more than 10 biomes with vertical layering. Confirmed biomes include Twisty Bridges (0-100m), Kelp Forest (20-160m), Crash Zone (0-180m), and Ice Shelf (0-80m). Predicted biomes based on visual patterns include Grand Reef (200-400m), Mushroom Forest (100-260m), and Abyssal Trench (1000m+). The map updates as new biomes are discovered.
Does the map track black boxes?
Yes. Every known black box location in the Ariadne Arm is plotted on the map with depth coordinates, biome orientation, and the story fragments each one reveals. Black boxes are the primary narrative collectible in Subnautica 2, containing logs from the Cicada mission and the Ariadne Arm outbreak.
Can I use the map for co-op sessions?
Absolutely. The Subnautica 2 map is designed for both solo and 4-player co-op planning. Share marked locations with your squad, assign dive roles, and coordinate resource gathering routes across the Ariadne Arm. The map includes a dedicated co-op guide with recommended unlock orders and role splits.
How is the map data sourced?
Every point of interest on the Subnautica 2 map is tagged with its source: confirmed from official Unknown Worlds footage and dev vlogs, community-sighted from player reports, or predicted from Subnautica franchise patterns. This transparency lets you decide how much weight to give each POI when planning your dives.
Is Subnautica 2 single-player or multiplayer?
Both. Subnautica 2 remains fully playable solo and also supports optional 1-4 player online co-op with PC and Xbox cross-play. The interactive map supports both play styles with dedicated guides for solo and team exploration routes.
What tools and resources does the map include?
The interactive map includes resource node locations (Titanium, Copper, Silver, Gold, Lithium, Magnetite and more), creature habitat zones with threat assessments, cave system entrances, wreck locations with salvageable fragments, and base-building resource route planners.
When will the map be updated for new content?
The map is actively maintained throughout Subnautica 2's Early Access period. Each major update (EA 1.1, EA 1.2, and future expansions) brings new biomes, creatures and resources. New POIs are added as soon as information is confirmed through official channels or reliable community reports.
