Subnautica 2 is heading into Early Access with four officially revealed leviathans, and the latest look at them shows the series is taking its sea monsters in a new direction. The sequel lands on a different planet from the original game and Below Zero, which means the creatures players meet this time are not carryovers but a fresh roster built for a new world.
The Collector Leviathan was the first to be shown, introduced in an official teaser trailer and later unpacked in a developer vlog that walked through the design process. After that came the Deepwing Brooder Leviathan, which the official Unknown Worlds website has only shown as a silhouette through a fan art challenge. As of the Early Access launch on May 14, 2026, no behavioral details, habitat information or size comparisons had been released for it.
The fourth reveal came in the Early Access Cinematic Trailer, which showed a stationary Leviathan modeled after a giant clam. It does not patrol territory in the usual sense; it sits in place, and that stillness does not make it harmless. Players who get caught inside its mouth are in danger, while swimming around the outside appears relatively safe. For a series built around creatures that can turn open water into a threat, that is a different kind of warning sign.
Leviathans remain the largest creature class in Subnautica, so every new reveal matters because these are the animals that shape how the game is read the moment players dive in. On a fresh planet, with no direct carryovers from Subnautica or Below Zero, the new lineup sets the tone for the entire early experience. The Collector Leviathan is the most documented of the four so far, but the Deepwing Brooder remains the most mysterious, and that gap is part of the draw.
The contrast is stark: one creature has been teased, then dissected in a dev vlog, while another has been reduced to a silhouette with almost nothing else known about it. That leaves Unknown Worlds with a clear visual hook but also a lot still held back. For now, the studio has shown enough to signal that subnautica 2 leviathans will not simply repeat what came before, and enough left unsaid to keep the biggest creatures in the game feeling unknown.
