Revision 3

The Jelly Plateaus is a biome on Planet Zezura in Subnautica 2. The name was discovered by community members who spotted file names visible in the background of a dev vlog video. It implies a plateau-style environment combined with jellyfish or jellyfish-like organisms as a defining feature.

What the Name Suggests

The biome name combines two elements: "plateaus" (flat, elevated terrain features) and "jelly" (suggesting jellyfish-like organisms or gelatinous biological structures). This points to an environment with broad, flat surfaces at depth, populated by bioluminescent jellyfish-like creatures that define the zone's visual identity and ecology.

Descriptions from the Planet Zezura article suggest the biome features thermal vents that provide geothermal energy sources, potentially useful for base building and power generation. If thermal vents are present, the biome could serve a practical role in the crafting progression by offering a favorable location for establishing a powered base.

Discovery

The biome name was identified through file names visible on a developer's screen during a dev vlog, the same method used to discover other Zezura biome names including the Coral Gardens, Kelp Forest, Sparse Plains, Overgrown Ruins, and World Tree. These names may change before or during Early Access.

What Remains Unknown

• Visual appearance of the jellyfish-like organisms

• Whether the organisms are passive ambient fauna, interactive, or hostile

• Depth range and placement in Zezura's biome progression

• Whether thermal vents are present and if they support base building

• Unique resources available in the biome

• Whether the biome is affected by the Blight

• Whether the dynamic weather system affects jellyfish behavior or bioluminescence

• Whether the Jelly Plateaus is included in Early Access launch or planned for a post-launch update
