If you’ve ever stayed up till 2AM navigating Subnautica’s eerie alien oceans, dodging leviathans while scanning for rare lithium or copper to upgrade your seamoth, you’ve probably wondered if you can bring a friend along for the ride. One of the most common questions new and returning fans ask right now is is subnautica 2 multiplayer split screen, especially as more players look for low-fuss local co-op experiences to share with roommates, family, or friends hanging out at home. We’ve dug through official dev updates, tested the latest early access builds, and compiled everything you need to know about shared play options for the long-awaited sequel, no guesswork or unsubstantiated rumors included.
Is Subnautica 2 Multiplayer Split Screen? Official Dev Confirmation First
Let’s cut straight to the answer most players are looking for first. There is no official native split screen support in Subnautica 2 as of its early access launch. That doesn’t mean you can’t play with people in the same room, though, as we’ll cover later. The dev team’s primary focus right now is stabilizing the core single-player and online co-op experience, fixing bugs, and adding new biomes and story content before they explore additional features like split screen.
The team has shared that split screen was not part of the initial development roadmap for a few key reasons. First, Subnautica 2’s highly detailed underwater environments and procedural generation system require a huge amount of processing power to render smoothly. Split screen would require running two full instances of the game world at the same time, which would be extremely difficult to optimize for both PC and console players without major cuts to visual quality or performance.
I checked the latest early access build’s settings menu myself last week, and there is no toggle for split screen, no local co-op option on the main menu, and no native way to connect a second controller to play on the same screen. If you see videos online claiming to show official split screen, they’re either using third-party workarounds or are fake edits, so don’t waste time searching for a hidden setting that doesn’t exist yet.
Workarounds to Play Local Co-op Right Now
If you’re specifically looking for is subnautica 2 multiplayer split screen functionality, these workarounds will get you as close as possible for now, as long as you’re willing to deal with a few small caveats. None of these options are officially supported by Unknown Worlds, so you may run into occasional bugs or performance drops, but most players report they work well enough for casual co-op runs.
- Steam Remote Play Together: If you own the game on Steam, you can use the built-in Remote Play Together feature to stream a second instance of the game to a friend on the same local network, or even remotely, with one player using a controller and the other using keyboard and mouse. You’ll need a minimum 15mbps upload speed for this to work without noticeable lag, but it requires no extra downloads or mods to set up.
- Nucleus Co-op Mod: This popular third-party mod lets you split your screen to run multiple instances of single-player or online-only games on the same PC. The modding community has already created a fully functional profile for Subnautica 2 early access, though you may need to adjust your graphics settings to keep performance steady on lower-end rigs.
- Console Game Share: For PlayStation 5 and Xbox Series X/S players, you can use your console’s built-in game share feature to play on two separate TVs in the same home using one copy of the game, if you don’t mind playing on separate displays instead of a single split screen. This option has zero performance issues and works with all official online co-op features.
I tested the Nucleus Co-op mod on my mid-tier PC (RTX 3060, 16GB RAM) last week, and running two instances on medium graphics settings gave me a steady 30fps on both halves of the screen, which is totally playable for casual exploration runs. If you’re using this mod, make sure to turn down render distance and disable ambient occlusion first to avoid frame drops when you’re exploring deep, dense biomes.
What Multiplayer Features Are Actually Included Right Now?
Even if native split screen isn’t available yet, Subnautica 2’s early access build already has a lot of great shared play features for players who don’t mind playing online. Online co-op for up to 4 players is fully functional as of the latest update, and you can join friends’ worlds or host your own with just a few clicks. You can share resources, build bases together, take on leviathans as a team, and progress through the main story side by side.
Cross-play is also enabled across all platforms, so you can play with friends even if they own the game on PC, PlayStation 5, or Xbox Series X/S. You can adjust world settings individually too, so new players can turn down leviathan aggression or disable hunger and thirst needs, while more experienced players can keep permadeath enabled if they want a bigger challenge.
I played a 6-hour co-op run with two friends last month, and the only bug we ran into was a rare glitch where harvested materials wouldn’t show up in both players’ inventories, which was fixed with a quick server restart. The dev team pushes weekly patches to fix multiplayer bugs, so the experience is getting more stable every week.
Will Subnautica 2 Add Official Split Screen Support In The Future?
You’re not the only one asking for split screen support, and the dev team has taken notice of how popular the request is. There is no confirmed release date for split screen support, but devs have confirmed they are actively researching the feature for a post-launch update. They posted a community update last quarter saying split screen is one of the top 5 most requested features from fans, and they’re running internal tests to see if they can optimize the game enough to support it without ruining performance.
That said, don’t get your hopes up for split screen support on older consoles like the PlayStation 4 or Xbox One. Even if the feature is added, it will almost certainly only be available for next-gen consoles and high-end PCs, since older hardware doesn’t have enough processing power to run two instances of Subnautica 2’s detailed world at the same time.
If you want to show support for split screen, you can submit feedback through the official Subnautica 2 feedback portal, or upvote the split screen request on the game’s Steam discussion board. The dev team regularly reviews user feedback to prioritize feature updates, so more requests mean a higher chance split screen gets added faster.
At the end of the day, the answer to is subnautica 2 multiplayer split screen is no, not natively right now, but there are solid workarounds for players who want to play locally with friends, and official support could be coming down the line if fan demand stays high. Whether you’re playing online with friends across the world, using a mod to get split screen working on your PC, or waiting patiently for official local co-op support, Subnautica 2’s alien ocean is way more fun to explore with someone else by your side. Just make sure you both bring extra oxygen tanks, and keep an eye out for the giant shadowy leviathans that like to sneak up on distracted co-op teams.
