Subnautica 2 multiplayer might take some of the fear out of your survival experience, but it's fun all the same. Despite isolation being part of what makes Subnautica great, multiplayer was among the first game's most requested features. That's why, according to Unknown Worlds devs, the team worked on the new game with multiplayer in mind from the off.

That doesn't mean the solo experience is any less haunting or satisfying in Subnautica 2, but it does mean that whichever way you want to play, you're covered. So, if you're looking forward to exploring the deep co-op with friends, here's what you need to know about Subnautica 2 multiplayer.

How Subnautica 2 multiplayer works

To play Subnuatica 2 multiplayer, you can either host or join a game, which plays out exactly like a single-player game, and the host and their friends can rejoin the game at any time. To invite friends, you can do so from your platform list or via an in-game friend code system.

You can even convert a single-player game into a multiplayer world from the main menu, so you don't have to sacrifice hours of work if someone joins later on, making this one of the most well thought out multiplayer experiences we've seen.

To maintain the solo experience, rest assured that nothing in Subnautica 2 needs other players to complete. However, the experience of exploring the vast alien ocean with friends completely changes the experience, which is why it's great news that Subnautica 2 has a multiplayer mode from day one. Even better is that it's seamless to join and play you multiplayer world, with or without your friends.

To invite friends from other platforms, you must use the friend code system. Create your own friend code and sent that to your pals or invite them using theirs. Either way, it's super simple to get going.

Since Subnautica 2 is available on both PC (across Steam and Epic Games) and Xbox, you might be wondering if you can play with friends on a different platform to you, too. Given how seamless multiplayer is, it will come as no surprise that Subnautica 2 is also crossplay enabled, meaning you can play with anyone else in-game. You can also play your own save between platforms thanks to Subnautica 2 cross platform capabilities.

After studying Music and Lifestyle journalism and writing a column for a stylish lifestyle magazine in her hometown of Brighton, Danielle finally found her feet writing about videogames for WePC in 2021. She then honed her guides writing skills at PCGamesN between 2022 and 2026, when she took those skills to GamesRadar as a Guides Writer. Danielle's guides are a safe space - she definitely got stuck before you did, which is why she's perfect for the job. When she's not replaying the Silent Hill games or a more up-to-date single-player horror game, you'll find her fighting for her life in Dead by Daylight, tending to a garden in Stardew Valley, or doing both in Minecraft.
