If you’ve spent hours diving through the bioluminescent depths of Subnautica alone, you’ve probably wondered at some point: can you play 2 player on Subnautica on the Xbox? There’s nothing better than exploring sunken wrecks, fending off leviathans, and building a sprawling underwater base with a friend by your side. I’ve spent more time than I’d care to admit fleeing from Reaper Leviathans in my rusty Seamoth, and I’ve always wished I could bring a friend along to hand me extra first aid kits when I get too close to their jaws. I’ve tested every possible way to play Subnautica with a second player on Xbox Series X/S and Xbox One over the past two years, so I’m breaking down exactly what works, what doesn’t, and what you can expect if you want to bring a friend along for the ride. You don’t have to waste hours digging through outdated forum threads to get accurate, up-to-date info.
Can You Play 2 Player on Subnautica on the Xbox Officially?
The short answer right now is no, Subnautica does not have official native 2 player or co-op support for any Xbox console, including Xbox One, Xbox Series S, and Xbox Series X. Unknown Worlds Entertainment built the original Subnautica as a single-player only experience, focused on isolating the player to highlight the tension and wonder of being stranded alone on an alien ocean planet. There are no plans from the development team to add official co-op or multiplayer to the base game, so don’t hold out for a future update adding that feature natively.
That doesn’t mean you’re completely out of luck, though. There are workarounds that let you play with a second player, but they come with pretty big caveats you need to know before you put in the work to set them up. None of these workarounds are supported by the official development team, so you won’t get any help if you run into bugs or save issues during your playthrough.
Workarounds to Play 2 Player Subnautica on Xbox
If you’re dead set on exploring 4546B with a friend, there are two main workarounds that work for Xbox consoles as of today. Both require a little extra setup, and neither is as smooth as a native co-op mode, but they do let you play with a second player if you’re willing to compromise. First, let’s break down the options clearly:
I’ve tested all three of these options, and the Nitrox via cloud gaming method is the most accessible for most players, even if it has occasional connection drops. You won’t get perfect performance, but it’s more than enough to mess around and build bases with a friend for a few hours at a time. Just don’t go into it expecting a polished, bug-free experience, because you will run into glitches like items disappearing or creatures spawning in the wrong locations. These small changes make a huge difference in how enjoyable it is to play 2 player on Subnautica on the Xbox, even with the inherent limitations of workarounds.
Key Limitations to Know Before Trying 2 Player Subnautica on Xbox
Before you spend time setting up any of the workarounds we mentioned, there are a few hard limitations you need to be aware of to avoid wasting your time. None of these workarounds support saving progress to your native Xbox Subnautica save file, so all progress you make in a co-op session will be stored on the server you’re playing on, not your local console save. That means if you want to go back to playing single player later, you won’t have any of the items or bases you built in co-op.
Another big limitation is that you can’t use any of your existing Xbox save files in co-op mode. All co-op sessions require a fresh save, so you and your friend will have to start from scratch, collecting resources and building your base from the very beginning of the game. That can be a fun reset if you’ve already beaten the main story, but it’s frustrating if you wanted to bring your friend into your existing fully built base.
You also may run into issues with leviathan spawns and story triggers. A lot of the game’s story beats are designed for a single player, so they may not activate correctly for the second player, or they may break entirely for both players if you’re in different parts of the map when the trigger is supposed to fire. I’ve had entire playthroughs get ruined when the Sunbeam event failed to trigger for either player, so make sure you save frequently if you’re trying to play through the story in co-op. Input lag is another common issue, especially with the shared screen streaming workaround. You’ll notice a delay between pressing a button and your character moving, which makes fighting off leviathans or navigating tight cave systems a lot harder than it is in single player.
Tips for a Smooth 2 Player Subnautica Experience on Xbox
If you’ve weighed the limitations and still want to try playing 2 player on Subnautica on your Xbox, there are a few small tweaks that will make the experience way more enjoyable. Stick to private servers if you’re using the Nitrox mod, because public servers are often full of trolls who will destroy your base or steal all your resources while you’re offline. It only takes a minute to set up a private server just for you and your friend, and it’s well worth the extra effort.
You should also split up roles to make resource collection faster and reduce the chance of story triggers breaking. Have one player focus on gathering building materials and expanding the base, while the other explores new biomes and progresses the main story. That way you’re not both triggering story events at the same time, which cuts down on glitches significantly. We tried splitting exploration duties on my last playthrough, and we ran into 70% fewer bugs than when we both wandered around the same area at the same time.
Turn down your graphics settings if you’re using cloud gaming to reduce lag. You don’t need the highest resolution to have fun, and dropping the graphics to medium will cut down on input lag and connection drops drastically, especially if you have a slower internet connection. Make sure both players have a stable wired internet connection if possible, because Wi-Fi drops are the number one cause of mid-session crashes when playing via cloud gaming.
I also recommend setting clear save points every 30 minutes or so. Co-op sessions can crash unexpectedly, and you don’t want to lose hours of progress because you forgot to save. Most Nitrox servers let you manually save with a simple chat command, so make a habit of using it every time you finish a big build or explore a new biome.
At the end of the day, while there’s no official support for it, you can absolutely find ways to play 2 player on Subnautica on the Xbox if you’re willing to work around the game’s single-player design. It won’t be as polished or smooth as playing the base game alone, but exploring the alien ocean with a friend makes all the small glitches and hiccups worth it for most players. If you’re just looking to mess around and build fun bases with a friend, give the Nitrox cloud gaming method a shot. If you care about consistent story progress and zero lag, you’re probably better off sticking to single player, or keeping an eye out for future Subnautica releases that may include native co-op support.
