Subnautica 2 Guide: All Confirmed Leviathans
Subnautica 2 Guide: All Confirmed Leviathans
I thought I was ready for Subnautica 2’s deep ocean. I had played the original, survived the Sea Dragon, and told myself multiple times that it was just a game and that large virtual creatures could not actually hurt me. Twenty minutes into my first real deep dive in Subnautica 2 on PC, something the size of a building drifted past my submarine in the dark, and I immediately surfaced and sat in my base for ten minutes doing nothing. That creature was a Leviathan. There are several of them. This guide covers every one confirmed in the current build, where they patrol, what they do, and, most importantly, how not to die to them immediately.
Every confirmed Leviathan in Subnautica 2 is explained, from the squid-like Collector to the mysterious flying giants seen in the cinematic trailer.
Subnautica 2 drops players onto a brand-new alien planet, and the ocean floor is anything but empty. Leviathans, the series’s signature class of colossal predators and passive giants, are back in full force. Four distinct creatures have been confirmed through trailers, dev vlogs, and official teasers, and they look nothing like the Reapers and Ghosts veterans encountered on 4546B. This guide breaks down every confirmed Leviathan, what we know about each creature’s behavior, and what to realistically expect when you finally come face-to-face with them.
What are Leviathans in Subnautica 2?
Leviathans are the largest creature class in the Subnautica series. They range from aggressive apex predators that will pursue your submersible across multiple biomes to passive giants that only become dangerous in specific situations. Subnautica 2 takes place on an entirely different planet from the original game and Subnautica: Below Zero, meaning players will encounter a completely new lineup of Leviathan species with no direct returning creatures from either previous title.
A total of four Leviathans have been officially revealed ahead of the Early Access launch. Some have received detailed profiles through developer coverage, while others remain little more than silhouettes or brief appearances in cinematic footage.

Collector Leviathan
The Collector was the first Leviathan I encountered properly, and it set the tone for everything that followed. It looks vaguely squid-like from a distance, which is somehow more unsettling than if it looked obviously monstrous. The way it moves through the water is wrong in a way that’s hard to articulate — too fluid, too purposeful, like it knows exactly where you are even when it hasn’t turned toward you yet. I spent my first encounter with it trying to stay completely still in my submarine, hoping it would pass. It did not pass.
The Collector operates in the mid-depth zones, which means you’ll encounter it earlier than most other Leviathans. It’s territorial rather than actively predatory — if you move through its zone without making too much noise or light, you can often avoid direct aggression. The mistake I made repeatedly was running my submarine engine at full power while trying to escape, which attracts it faster than almost anything else. Cut the engine, drift, wait for it to lose interest. Patience is your best tool here.
Threat level: High — Dangerous but avoidable with careful movement.
Deepwing Brooder Leviathan
The Deepwing Brooder Leviathan is easily the most mysterious creature on this list. Unknown Worlds has only revealed its silhouette so far, which appeared as part of a Fan Art Challenge shared on the studio’s official website. No concrete details regarding its behavior, habitat, or overall size had been revealed by the time Subnautica 2 entered Early Access on May 14, 2026.
Its name alone raises plenty of interesting possibilities. The term “Brooder” hints at parental or nesting instincts, potentially suggesting a creature that becomes far more aggressive in certain situations, much like real-world deep-sea species that fiercely protect their eggs. However, this remains purely speculative, as Unknown Worlds has not confirmed any of these behaviors.
Unknown Clam Leviathan
Spotted during the Early Access Cinematic Trailer, this creature appears to be a stationary Leviathan modeled after a giant clam. Based on what the trailer shows, it sits in place rather than actively patrolling a territory. The threat seems conditional: get caught inside its mouth, and you’re in serious trouble, but swimming around the outside appears relatively safe.
This design echoes a pattern from the original Subnautica, where not every Leviathan-class creature was an active hunter. The Sea Dragon was a direct threat, but the Sea Emperor was passive. The Clam Leviathan looks like it fits the passive-but-deadly category, where player awareness matters more than raw speed or evasion.
Unknown Flying Leviathan
Also appearing in the Early Access cinematic trailer, several flying creatures can be seen that appear to qualify as Leviathan-class based on their enormous size. Unlike the Clam Leviathan, these creatures seem entirely peaceful, drifting through the environment without showing any reaction to the player. Their role may be more atmospheric, similar to the Subnautica series’ Sea Treader Leviathans, which functioned as passive herd creatures in the original game.
The introduction of flying Leviathans marks a major shift for the series. Both previous games focused almost exclusively on underwater exploration, so creatures of this scale soaring above the environment suggest that Subnautica 2 could place far greater emphasis on surface and aerial regions than players initially expected.
Are Any Leviathans Returning From the Original Games?
The short answer is no, and that appears to be entirely intentional. Subnautica 2 takes place on a completely different planet from both the original Subnautica and Subnautica: Below Zero. Unknown Worlds followed a similar design philosophy to Below Zero. Even though that game was set on the same planet as the original, creatures like the Reaper Leviathan and Ghost Leviathan were absent from Sector Zero because the region had its own distinct ecosystem.
With an entirely new planet in Subnautica 2, there is even less reason to expect older Leviathans to return as living threats. The ecosystem is completely alien, and every confirmed creature revealed so far looks vastly different from the wildlife found on 4546B.
That said, Unknown Worlds is still giving longtime fans a small callback. A statue of the Reaper Leviathan from the original game will reportedly be available as a base decoration, serving as a nostalgic reference without disrupting the ecological consistency of the new setting.
General Leviathan Survival Tips
After too many near-death experiences across multiple dives, I worked out a set of rules that kept me alive consistently. First — sound matters more than light at deep depths. Running your engine at full power is like ringing a dinner bell. Second, vertical movement confuses most Leviathans more effectively than horizontal escape. When one locks onto you, dive or ascend sharply rather than just trying to outrun it on the same plane. Third — your base is not safe if you built it inside a Leviathan’s territory. I learned this one the hard way at about 2 am when something started attacking my base walls while I was organising my inventory.
The most important thing I can tell you is to learn what each Leviathan sounds like before you see it. Every one of them has a distinct audio cue that plays before they enter visual range. By my third full playthrough session on PC, I could identify which creature was nearby just from the sound, which gave me enough time to cut my engine and change direction before things got dangerous. The ocean in Subnautica 2 is terrifying,g but it’s a fair kind of terrifying — it gives you the tools to survive if you pay attention.
Final Thoughts
Subnautica 2’s Leviathans are the best argument for why this series works where other survival games don’t. They’re not just big health bars with teeth. They’re environmental storytelling — each one tells you something about the depth you’re in, the danger level of the zone, and what the ocean floor has had millions of years to evolve into without humans anywhere near it. Learning to coexist with them rather than avoid them entirely is one of the most satisfying progressions in the game. You’ll go from panicking every time you hear that low rumble to calmly adjusting your course and moving on. That shift is genuinely earned.

I like the confirmed-guide framing because game coverage can easily blur known facts, estimates, and wishful thinking. That same problem shows up in engine coverage. I maintain Game Engine Tracker as a sourced Unreal Engine 6 release date tracker that labels claims as confirmed, estimated, or unknown instead of treating rumors as official. Do Subnautica 2 readers ask more about confirmed mechanics or about the timing of future updates?
We cover both future updates and confirmed mechanics and are willing to cover all topics asked about my our readers. Which usually tends to be about confirmed mechanics
