Biomes and area references
Find a named area and the concrete update context that can help with a visit. This is a selected index of official references, not an exhaustive biome count or a hierarchy of every region and sub-biome. Reviewed October 18, 2026.
Coral Gardens
July 8 added a Biolab and changed Silver hints and availability.
Axum Ruins
July 8 added a Biolab. This does not locate its entrance or establish a measured region boundary.
Old Habitat
July 8 corrected overlapping Copper nodes in a nearby cave. Old Habitat is a named landmark in this context, not a claimed separate biome.
Shallows
July 8 corrected a gatherable Quartz Crystal node on a broken Coral Dome. It does not give a complete resource table or a safe depth range.
Root Canyon
August 19 corrected the voice-over timing at Axum Metal Farms in Root Canyon: the line belongs to scanning the farm.
Overgrown Ruins
October 6 corrected currents and missing names on previously unlocked Blackbox signals after loading a save.
The Early Access boundary, the Void and map size
The August 19 update describes an Early Access fence, a disabled-building notice for multiplayer clients who cross it and recovery of Tadpoles destroyed outside it. The October 6 hotfix fixes incorrect out-of-bounds teleportation, improves recovery of destroyed vehicles with chassis modules and stops the Shiver Leviathan interacting with unpiloted vehicles. These notes establish a boundary system; they publish no square-kilometre map size, Void depth or route to Xanadu or the World Tree.
For depth, the community data on the map gives object positions rather than a terrain survey. Its deepest large resource deposit record is Atacamite at about 475 m. A named area in a patch note does not establish its exact depth or every adjacent biome.
Choose by the problem, not just the area name
If you need Silver, a resource hint change is more relevant than a broad region description. If a ruins signal lacks text, compare the October fix. If the question is whether a future region is playable, read roadmap status; a preview is not evidence of current access.
How many biomes are confirmed here?
This index does not establish a total. It mixes area and landmark names only to show their precise source context; the number of cards is not the number of biomes in the game.
