Note on Scope
This biome page was authored from pre-launch materials. The name does not appear in the shipped Early Access build's region list, which as of September 2026 covers Coral Gardens, Sparse Plains, Karakorum and the Void, with Xanadu announced but out of bounds. The page is kept as a development-history record of a name that circulated before launch, not as a confirmation that the area exists in the game. See Biomes for the confirmed list.
VepZone is a biome on Proteus in Subnautica 2. The name was discovered by community members who spotted file names visible in the background of a dev vlog video. It is the most enigmatic of the discovered biome names: unlike the Kelp Forest, Coral Gardens, or Sparse Plains (whose names suggest their environment), "VepZone" does not correspond to any obvious real-world reference or biological term.
Discovery
The biome name was identified through the same method used to discover other Proteus biome names: file names visible on a developer's screen during a dev vlog. The unusual naming convention (camelCase with a capitalized "Z") suggests it may be an internal designation, a placeholder, or a name derived from Proteus-specific terminology that does not map to Earth biology or geology.
These names come from development files and may not represent final naming. The developers stated biome names could change before or during Early Access. VepZone is a particularly likely candidate for renaming given its internal-sounding format.
Speculation
The community has speculated about what "Vep" could refer to. Possibilities include an abbreviation for a developer-internal term, a reference to a Proteus-native organism or material, or simply a working name that will be replaced with a more descriptive title. No developer has commented on the name's meaning or the biome's contents.
What Remains Unknown
One question is settled: VepZone is not among the regions that shipped in Early Access. Everything else about it remains unknown, and nothing has been added since launch:
What the biome looks like
What the name "Vep" refers to
Depth range and difficulty level
Whether the name was retired, renamed, or belongs to content held for a later Early Access update
Whether the name will change before release
This article will be updated as more information is revealed.
