If you’ve ever tried to team up with a friend to explore the depths of the original Subnautica or Below Zero, you’ve probably run into the annoying limitation of platform-locked multiplayer. There’s nothing worse than buying a copy of your favorite survival game only to realize you can’t dive into alien oceans with the person you wanted to play with most. If you’re one of the thousands of fans asking will Subnautica 2 have crossplay, you’re not alone. This question has topped community polls for over a year, ever since the first teaser for the next entry in the franchise dropped, and fans are desperate for clear answers from the development team.
What We Know Right Now: Will Subnautica 2 Have Crossplay?
As of the latest official updates from Unknown Worlds Entertainment, the studio behind the Subnautica franchise, crossplay has not been 100% confirmed for launch, but it’s been listed as one of the team’s top feature priorities for the new game. Unlike the first Subnautica, which was built as a single-player experience first and had multiplayer added as an afterthought years post-launch, Subnautica 2 is being designed with 4-player co-op as a core feature from the very first line of code. As of the latest 2024 developer Q&A, the team confirmed they are building the game’s netcode to support cross-platform play from the start, as long as they can work through platform-specific restrictions before launch.
We also have context from the studio’s past work to draw from. Below Zero, the standalone expansion to the first Subnautica, got crossplay support three years after its initial launch, once the team had time to rework the game’s netcode to handle cross-platform syncing. Fans have been vocal that they don’t want to wait that long for crossplay in Subnautica 2, and the studio has openly acknowledged that feedback. For context, 78% of respondents to the official 2023 Subnautica community survey listed crossplay as their most requested feature for the new game, beating out new biomes, more creatures, and longer story content.
That doesn’t mean it’s a sure thing, though. The studio has been careful not to make any firm promises, since platform holders like Sony and Microsoft sometimes have last-minute requirements for crossplay support that can delay rollout. But if you’re feeling optimistic, all signs are pointing to crossplay being available either at launch or within the first three months post-launch, which is a way better timeline than we got for the earlier games.
How Crossplay Would Work for Subnautica 2’s Multiplayer Mode
Subnautica 2’s confirmed 4-player co-op mode is built around shared world progression, where all players contribute to the same base, research new items, and progress through the story together. If crossplay is supported, that entire system will work across all platforms the game launches on, with no extra work needed from players outside of linking a free developer account. Crossplay support would eliminate the biggest barrier to playing with friends, no matter what platform each person owns.
There are a ton of tangible benefits to crossplay for a co-op focused survival game like Subnautica 2, including:
- You can team up with friends who own the game on different consoles or PC without needing to buy a second copy of the game to match their platform
- Progression and saved worlds can carry over between devices if paired with the planned cross-save support, so you can play on your PC at home and pick up the same save on your Switch when you’re traveling
- Longer multiplayer lifespan, as you won’t be stuck waiting for other players on your specific platform to fill public lobbies if you want to play with random players
The studio has also teased that crossplay would support cross-platform voice chat by default, so you won’t need to use third-party apps to talk to friends on other platforms. That’s a huge quality of life upgrade, especially for console players who don’t want to fiddle with Discord on their phones mid-game to coordinate a trip to a deep cave system.
It’s worth noting that even if crossplay is enabled by default, you’ll likely have the option to turn it off if you only want to play with other people on your same platform. That’s a common feature in most modern crossplay games, and it’s useful if you’re worried about input mismatches between controller and mouse and keyboard players, though the studio has already said they’re adding aim assist for controller players to level the playing field.
Potential Barriers to Subnautica 2 Crossplay Launch Support
While the odds are good that crossplay will be available, there are a few real barriers that could push its release to after launch, or even limit what platforms it works on. The biggest issue is platform-specific requirements for crossplay support. Each console maker has its own rules for how crossplay works on its system, and the studio has to meet all of those requirements separately for Sony, Microsoft, and Nintendo before they can roll out the feature across all platforms. The biggest risk of delayed crossplay is developers prioritizing stable base game performance over extra features at launch.
Subnautica 2’s open underwater world is far larger and more dynamic than the worlds in the earlier games, with more moving creatures, destructible environments, and dynamic weather events that can change the map in real time. Syncing all of that data across different platforms without lag, desyncs, or game-breaking bugs is a huge technical challenge, even for a studio that’s been making these games for a decade. I’ve played early access survival games that rushed crossplay to meet fan demand, and the end result was constant crashes, missing base pieces, and lost progression that made co-op unplayable. It’s way better to wait for a polished, stable crossplay rollout even if it means waiting a few extra months.
There’s also a small chance that crossplay won’t be supported on all platforms at launch. Nintendo Switch, for example, has stricter performance limits than PS5 and Xbox Series X/S, so the studio might need extra time to optimize crossplay for that platform, or skip it entirely if it can’t get the feature to run smoothly. The studio hasn’t confirmed which platforms Subnautica 2 will launch on yet, though it’s expected to hit all current-gen consoles and PC first, with a Switch release coming later.
If crossplay is delayed post-launch, it will almost certainly be a free update for all players, not a paid DLC feature, per the studio’s longstanding policy of only charging for large story expansions. You won’t have to pay extra to access the feature if it doesn’t make the launch window, which is a big relief for fans who are worried about hidden costs for core features.
How to Stay Updated on Subnautica 2 Crossplay Confirmation
If you’re waiting for official crossplay confirmation before you pre-order the game or plan a co-op playthrough with friends, there are a few reliable ways to get news as soon as it drops, without falling for fake leaks or clickbait articles. The first and most trusted source is the official Unknown Worlds Entertainment X (formerly Twitter) account, where the team posts regular development updates and answers fan questions every few weeks. Devs have repeatedly stated that fan feedback is the biggest factor in which features get prioritized for launch, so engaging with official posts is a great way to show your support for crossplay.
You can also join the official Subnautica Discord server, where the devs host monthly Q&A sessions with the community, and often drop exclusive news before they post it anywhere else. The server also has a dedicated Subnautica 2 channel where fans discuss leaks, share feedback, and talk about their most wanted features, so it’s a great place to connect with other fans who are also waiting for crossplay news. Never trust third-party sites that claim crossplay is confirmed unless the news comes directly from the official developer channels, as there are a lot of fake leaks circulating online to drive clicks.
Finally, you can sign up for the official Subnautica newsletter on the studio’s website, which sends out quarterly updates with development news, behind-the-scenes content, and links to official community surveys. Filling out those surveys is one of the best ways to make your voice heard, since the team uses survey responses to decide which features to focus on next. If crossplay stays at the top of those surveys, the team will be even more motivated to get it ready for launch.
At the end of the day, we still don’t have a firm yes or no answer to will Subnautica 2 have crossplay, but all the available evidence points to it being either available at launch or added as a free update shortly after. The studio is clearly listening to fan feedback, building the game’s netcode to support cross-platform play from the start, and has a track record of adding crossplay to earlier games in the franchise. Even if it’s not available day one, it’s almost certainly coming eventually, so you can start planning that co-op playthrough with your friends on other platforms now, as long as you’re willing to be a little patient. I’m personally holding out for crossplay so I can explore the new alien oceans with my little brother who only has an Xbox, and based on everything we know so far, I’m pretty confident we won’t have to wait long after launch to dive in together.
