Subnautica 2 on Game Pass: What to Expect

There’s something irresistible about the unknown. The Subnautica series has always tapped into that primal urge—to explore, to adapt, to survive in places where the rules are foreign and the risks feel real. And now, with Subnautica 2 surfacing on the horizon, fans are watching closely. One question bubbles to the top: Is Subnautica 2 coming to Xbox Game Pass?

The answer is yes—and there’s a lot more under the surface.

Xbox Game Pass: Your All-Access Pass to the Deep

Unknown Worlds Entertainment has confirmed that Subnautica 2 will arrive in early access in 2025, and Xbox Game Pass subscribers will be among the first to experience it. The game is expected to launch on Xbox Series X|S as well as PC via platforms like Steam and the Microsoft Store. For those in the Game Pass ecosystem, this means immediate access to one of the most anticipated survival experiences in years.

This early access phase isn’t just a technicality—it’s a design choice. Just like with the original Subnautica, the developers are inviting the community to help shape the game through feedback, bug reports, and gameplay suggestions. It’s an open-ocean approach to game development.

Subnautica 2: What’s New and What Stays

If you're returning to the water, know this isn’t just a rehash. Subnautica 2 expands the formula in bold ways:

• Multiplayer: For the first time, players can explore with friends. The game supports up to four-player co-op, allowing you to share the thrill (and the fear) of the unknown.
• New Planet: Say goodbye to planet 4546B. This sequel takes place on a different alien world, one that is even more mysterious and unpredictable.
• Genetic Tweaks: One of the wildest new features is the ability to modify your DNA by integrating traits from local fauna. It’s survival, but with a twist that lets you evolve with the environment.
• Unreal Engine 5: The shift to this powerful game engine means sharper visuals, smoother animations, and biomes that feel alive in ways we haven’t seen before.

That said, the core of Subnautica remains intact—an open-world survival game grounded in tension, exploration, and crafting, all driven by subtle narrative threads that unravel as you descend deeper into the unknown.

Comparison with Earlier Titles

To understand what’s different, let’s compare:

The original Subnautica launched in 2018 with a single-player experience set on planet 4546B. It used Unity as its engine and offered an isolated survival journey. The sequel, Below Zero, followed with a more character-driven story and the same engine. Both games emphasized solo exploration, environmental storytelling, and base-building.

Subnautica 2, however, switches things up. It’s built in Unreal Engine 5 and introduces cooperative multiplayer. The setting changes to a new alien planet, the mechanics are more advanced (especially with DNA modification), and the development is once again being done in close partnership with the player community through early access.

Steam vs Game Pass: Where Should You Play?

If you're a Steam loyalist, Subnautica 2 will still be there for you. PC players who prefer the modding capabilities and social features of Steam can join the early access program alongside Xbox Game Pass users. If you want to prepare ahead of time, now's the perfect opportunity to buy a Subnautica Steam CD Key and revisit the original adventure.

However, for those who like their games bundled into a subscription, Xbox Game Pass will offer a seamless way to experience the sequel without any additional purchase. It’s a practical option, especially for those who already have a Game Pass library or want to experience the game on both console and PC.

Early Access: A Two-Way Street

The early access window is expected to last between two to three years, based on the studio’s previous timelines. That means Subnautica 2 won’t be a quick in-and-out experience. It’s going to grow over time, with content updates, new biomes, mechanical tweaks, and creature additions happening frequently.

Players who jump in early will help influence these changes. It’s not about playing a half-finished game—it’s about being part of the creative current that guides it forward.

What's Still Unknown?

A few things are still up in the air:

• PlayStation Availability: As of now, there’s no confirmation of a PlayStation 5 release. While the previous titles eventually reached Sony’s platforms, early access on PlayStation is rare, so fans may have to wait.
• Switch Port: Given the hardware limitations and the technical demands of Unreal Engine 5, it’s unclear whether a Nintendo Switch version is even in the plans.
• Mod Support: While Steam naturally supports modding, it remains to be seen how official or extensive modding support will be in the new game.

The Verdict: Should You Be Excited?

If you're a fan of exploration, tense survival mechanics, and the unpredictable beauty of alien ecosystems, then yes—Subnautica 2 should absolutely be on your radar. Its arrival on Game Pass makes it more accessible than ever, and the evolution of its mechanics promises a richer, deeper, and more collaborative experience.

Whether you choose Steam or Game Pass, solo or with friends, early access or final release, the water is calling.

And if you're new to the series or want to reacquaint yourself with the foundations, grab a Subnautica Steam CD Key and let the original remind you why this universe is worth returning to.

2025 isn’t far. The currents are shifting, and something new is rising from the depths. With Subnautica 2 dropping anchor on Xbox Game Pass, it’s not just about survival anymore. It’s about discovery, evolution, and teamwork.
