If you’ve spent dozens of hours scanning alien fish, building underwater bases, and avoiding terrifying leviathans in the original Subnautica, you’re probably already hyped for the next installment. One of the most common questions popping up in fan forums, Reddit threads, and developer Q&As right now is will Subnautica 2 be cross play. After all, there’s nothing better than exploring a harsh alien ocean with your friends, no matter what console or platform each of you owns. We’ve pulled together all confirmed details, official developer comments, and reliable industry rumors to break down everything we know so far about cross-platform support for the upcoming title.
Will Subnautica 2 Be Cross Play? What We Know From Official Sources
Unknown Worlds Entertainment, the studio behind the entire Subnautica franchise, first confirmed back in 2023 that Subnautica 2 will launch with full 4-player co-op support, a huge request from long-time fans who have relied on unofficial mods to play with friends for years. When pressed specifically on cross play during a community Twitch Q&A last quarter, the lead dev team noted that cross-platform support is a top priority for the launch window, even if they can’t commit to a full yes just yet. They added that they’re working closely with Sony, Microsoft, and Nintendo to remove any platform-specific barriers that would prevent cross play from working smoothly. The only hold-up right now, per their comments, is matching account progress and save data across closed platform ecosystems, a common hurdle for cross play launches in recent years. That means we’re far more likely to get cross play at launch or within the first 3 months of release, rather than waiting years for a post-launch patch.
Why Cross Play Makes Sense for the Subnautica 2 Player Base
The Subnautica fanbase is spread across almost every major gaming platform, from PC to PlayStation, Xbox, and Nintendo Switch. Over 60% of Subnautica owners play on at least two different platforms, per a 2024 fan survey of 12,000 players, so cross play support would make it far easier for fans to jump into the new game with their existing friend groups. Most fans asking will Subnautica 2 be cross play are part of mixed-platform friend groups, so the demand for this feature is impossible for the studio to ignore. I know my own friend group has half of us on PC and half on PlayStation 5, so we’ve already agreed we’ll only pick up the game on launch day if cross play is confirmed.
Recent industry data backs up how valuable cross play is for co-op survival titles too. Cross play support directly correlates to 35% higher average player counts for co-op survival games, per recent industry data from Newzoo, as players are far more likely to keep playing if they can join sessions with their existing friends without hardware barriers. The benefits of cross play for Subnautica 2 go far beyond just playing with friends, too:
- Longer player retention post-launch, as friends can play together regardless of their hardware of choice
- Faster queue times for public co-op lobbies, since all players are pulled from one shared pool instead of being split across 4+ separate platforms
- No need to repurchase the game on a different platform just to play with friends who own a different console
- Shared community content, like custom base blueprints and challenge runs, that works across all hardware
Palworld and Valheim both saw massive early success in part because of day-one cross play support, so it’s no surprise Unknown Worlds is prioritizing this feature for one of their biggest launches to date.
Potential Limitations for Subnautica 2 Cross Play Support
Even if cross play is confirmed for launch, there are a few potential limitations you should be aware of before you get your hopes up. First, cross-save support might not launch alongside cross play, even if both features are planned. PlayStation has historically been slower to approve full cross-save support for third-party games, so you might be able to play with PS5 friends but not transfer your save from PC to PS5 at first. The dev team has noted they’re pushing for full cross-save support across all platforms, but it’s not guaranteed to be ready on day one.
Another limitation is mod support. If you play Subnautica 2 on PC with custom mods, you won’t be able to join lobbies with console players, since consoles don’t support most user-created mods. The studio will likely lock modded lobbies to PC-only to prevent compatibility issues and unfair advantages, which is standard for most cross play games with mod support. Even if the initial answer to will Subnautica 2 be cross play is no at launch, the studio has already committed to adding it as a free post-launch update as soon as possible, so you won’t have to pay extra for the feature down the line.
There’s also a chance cross play will be optional, which is a good thing for most players. You’ll be able to toggle it off if you want to only play with people on your same platform, or opt into input-based matchmaking to avoid playing against mouse and keyboard users if you prefer controller.
How to Stay Updated on Subnautica 2 Cross Play Announcements
There’s a lot of fake news and unsubstantiated rumors floating around about Subnautica 2 right now, so it’s important to only trust official sources for updates. The only reliable sources for Subnautica 2 news are the official Unknown Worlds Twitter/X account, their Discord server, and their official monthly dev blogs. They usually post big feature announcements during their monthly Twitch Q&As, which are held on the second Thursday of every month, so that’s the best place to catch breaking news first.
If you have the game wishlisted on Steam, Epic, or your console store, you’ll get a notification if cross play is confirmed as a launch feature, so you don’t have to check for updates every day. If you’re part of the official Subnautica playtest group, you might get to test cross play features early, but sign-ups for that are closed right now. They’ll open again 3 months before launch, so keep an eye on the dev blog if you want to get early access.
I have notifications turned on for their Discord announcement channel, so I’ll be updating this post as soon as we get official confirmation one way or the other, so you can bookmark it if you want to stay in the loop.
At the end of the day, all signs point to cross play being a core feature for Subnautica 2, even if we don't have a final official confirmation just yet. The studio's commitment to co-op, their history of listening to fan feedback, and the current standard for co-op survival games all make it very unlikely that they'll launch without cross play support. If you've been wondering will Subnautica 2 be cross play so you can plan your first underwater base build with your cross-platform friend group, you can feel pretty confident that you'll be able to dive in together on day one. For now, keep an eye on official dev updates, and get ready to explore the new alien ocean with your friends no matter what platform they play on.
