Leaked / Unconfirmed Biomes

Kelp Forest

Overgrown Ruins
highA mysterious biome spotted in leaked file names from a Subnautica 2 developer vlog. The name suggests ancient structures reclaimed by marine life — raising community questions about whether these are Precursor ruins, old human remnants, or something entirely new to planet Zezura.
Surface biome
World Tree
mediumOne of the most intriguing biomes spotted in leaked Subnautica 2 file names. The World Tree biome suggests a massive central structure — possibly a giant alien tree or coral formation — around which an entire ecosystem has formed. Community speculation points to this being a major story location.
Surface biome
Void
extremeA leaked biome name from Subnautica 2 development files. In the original Subnautica, the Crater Edge (commonly called the Void) was the open ocean beyond the map boundary — home to massive Ghost Leviathans and an invisible wall. Whether the Void in Subnautica 2 serves a similar boundary role or is a fully explorable biome is unknown.
