What it doesn&#8217;t have, as of October 2026, is official dedicated servers: one player hosts the world. Here&#8217;s everything Unknown Worlds has confirmed about co-op, crossplay, save sharing and the Buddy System update, taken from the studio&#8217;s own help centre and patch notes.<\/p>\n<h2>Subnautica 2 multiplayer at a glance<\/h2>\n<table><tbody>\n<tr><td><strong>Players<\/strong><\/td><td>1\u20134 (solo or online co-op with up to three friends)<\/td><\/tr>\n<tr><td><strong>Hosting<\/strong><\/td><td>One player hosts the session; no official dedicated servers<\/td><\/tr>\n<tr><td><strong>Crossplay<\/strong><\/td><td>Yes, across Steam, Epic Games Store, Windows Store and Xbox Series X|S<\/td><\/tr>\n<tr><td><strong>Save sharing<\/strong><\/td><td>Yes, across platforms with a cloud save code<\/td><\/tr>\n<tr><td><strong>Voice chat<\/strong><\/td><td>Proximity voice chat since the Buddy System update (19 August 2026)<\/td><\/tr>\n<tr><td><strong>Xbox<\/strong><\/td><td>Online multiplayer needs a Game Pass subscription (any tier)<\/td><\/tr>\n<tr><td><strong>Price<\/strong><\/td><td>\u00a325.99 \/ $29.99 (Early Access)<\/td><\/tr>\n<tr><td><strong>Steam reviews<\/strong><\/td><td>Very Positive (91% of 128,000+)<\/td><\/tr>\n<\/tbody><\/table>\n<h2>Does Subnautica 2 have dedicated servers?<\/h2>\n<p>No, not officially. In Subnautica 2, one player hosts the co-op world from the game&#8217;s <strong>Host Multiplayer<\/strong> menu and friends join that session. Unknown Worlds hasn&#8217;t released dedicated server files, and neither its help centre nor its patch notes announce them for Early Access. The studio&#8217;s own support advice also shows how it works: if you&#8217;re hosting and the session lags, it recommends lowering your graphics settings, because your PC is running the game for everyone.<\/p>\n<p>Some server-hosting companies advertise Subnautica 2 servers. Without official server software, check exactly what you&#8217;d be paying for before you sign up. We&#8217;ll update this article if Unknown Worlds announces dedicated servers.<\/p>\n<h2>How does Subnautica 2 multiplayer work?<\/h2>\n<p>You start a world in <strong>Multiplayer<\/strong> mode and invite friends with a code. The official steps are:<\/p>\n<ul>\n<li><strong>To add a friend:<\/strong> Main Menu \u2192 Play with Friends \u2192 Friend Code, then enter your friend&#8217;s code.<\/li>\n<li><strong>To be invited:<\/strong> Main Menu \u2192 Play with Friends \u2192 Generate Code, then send the code to your friend.<\/li>\n<\/ul>\n<p>You don&#8217;t need a separate account. Unknown Worlds says you play with the account from the store you bought the game on (Steam, Epic or Xbox), with no third-party sign-up or linking.<\/p>\n<h3>Can you turn a single-player save into co-op?<\/h3>\n<p>Yes. Go to Main Menu \u2192 Play Single Player, pick your save and choose <strong>Convert to Multiplayer<\/strong>. It works the other way too: Main Menu \u2192 Host Multiplayer, pick the save and choose <strong>Convert to Single Player<\/strong>.<\/p>\n<h3>Can friends keep playing without the host?<\/h3>\n<p>The world lives in the host&#8217;s save, so friends join the host&#8217;s session. If someone else wants to carry on the same world, the host can share the save with them using a cloud save code (see below), and they can then host it themselves.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-thumbnail aligncenter wp-image-24758\" src=\"https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-tadpole-moonpool-800x450-1.webp\" alt=\"The Tadpole submersible docked in a base moonpool in Subnautica 2\" width=\"800\" height=\"450\" srcset=\"https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-tadpole-moonpool-800x450-1.webp 800w, https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-tadpole-moonpool-800x450-1-768x432.webp 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<h2>Is Subnautica 2 crossplay?<\/h2>\n<p>Yes. Unknown Worlds says the in-game invite system lets you join friends across <strong>all supported platforms<\/strong>, and Steam lists cross-platform multiplayer. That covers PC on Steam, the Epic Games Store and the Windows Store, plus Xbox Series X|S. The studio&#8217;s multiplayer dev vlog also covered crossplay on handhelds, including the <strong>Steam Deck<\/strong> and the <strong>ROG Xbox Ally<\/strong> series.<\/p>\n<p>One catch: everyone in a session has to be on the same version of the game. Players on the opt-in <strong>Experimental branch<\/strong> can&#8217;t join players on the default build.<\/p>\n<h2>Can you share Subnautica 2 saves across platforms?<\/h2>\n<p>Yes. Open your saved games (single-player or multiplayer), select a save and choose <strong>Save to Cloud<\/strong>. Copy the code it generates, then enter it under <strong>Import Save File<\/strong> (bottom left of the main menu) on the other platform. Since the Buddy System update, you can paste save codes straight into the box. Saves can&#8217;t be moved between the Experimental and default branches this way.<\/p>\n<h2>What did the Buddy System update add to multiplayer?<\/h2>\n<p>Early Access 1.2, the <strong>Buddy System<\/strong> update, arrived on <strong>19 August 2026<\/strong> and was built around playing together:<\/p>\n<ul>\n<li><strong>Proximity voice chat:<\/strong> players get harder to hear as they move apart. You can set it to always on, push to talk or always off.<\/li>\n<li><strong>Revives:<\/strong> players can revive each other before reprinting. Revived players keep their equipment and get back a little oxygen.<\/li>\n<li><strong>Player trading:<\/strong> you can hand items directly to another player.<\/li>\n<li><strong>Emotes:<\/strong> Wave, Clap, Thumbs Up, Thumbs Down and Frustrated, from a new radial menu.<\/li>\n<li><strong>Tracking Tag:<\/strong> a short-range beacon you can put in a locker or other carryable.<\/li>\n<li><strong>Two new characters<\/strong>, Jegna and Grace, plus new colour schemes.<\/li>\n<li><strong>Multiplayer fixes<\/strong>, including clients desyncing when moving Growbed items and base pieces being invisible to players with high latency.<\/li>\n<\/ul>\n<p>Two follow-up hotfixes fixed more co-op problems. The second, on <strong>6 October<\/strong>, improved voice chat detection and fixed players seeing the host as dead after their own death. An earlier update (Early Access 1.1, 8 July) had already stopped audiologs from auto-playing for everyone in a session.<\/p>\n<h2>Watch the Subnautica 2 Buddy System trailer<\/h2>\n<p><a href=\"https:\/\/www.youtube.com\/watch?v=8Dj9l5cebEc\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" decoding=\"async\" class=\"size-thumbnail aligncenter wp-image-24762\" src=\"https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-buddy-system-update-trailer-800x450-1.webp\" alt=\"Watch the official Subnautica 2 Buddy System update trailer\" width=\"800\" height=\"450\" srcset=\"https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-buddy-system-update-trailer-800x450-1.webp 800w, https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-buddy-system-update-trailer-800x450-1-768x432.webp 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/a><\/p>\n<p>The official Buddy System update trailer from the Subnautica YouTube channel.<\/p>\n<h2>Do you need Game Pass for Subnautica 2 multiplayer on Xbox?<\/h2>\n<p>Yes. Unknown Worlds&#8217; Early Access 1.1 notes say a <strong>Game Pass subscription (any tier)<\/strong> is required to play multiplayer on Xbox, and the game now shows a notice if you try without one. Subnautica 2 is also included with Xbox Game Pass. On PC, online co-op needs no subscription.<\/p>\n<h2>Is Subnautica 2 on PS5 or Switch?<\/h2>\n<p>Not at the moment. Subnautica 2 is on <strong>PC (Steam, Epic and the Windows Store)<\/strong> and <strong>Xbox Series X|S<\/strong>. Unknown Worlds says &#8220;more may be added in the future&#8221;, but there&#8217;s no PlayStation or Nintendo version announced. There&#8217;s no official macOS or Linux support either, though the studio is working to make sure it runs on the Steam Deck.<\/p>\n<h2>Is Subnautica 2 a single-player game?<\/h2>\n<p>Yes. Unknown Worlds calls it a &#8220;single-player first experience&#8221;. Co-op is optional, and the full story and world are the same whether you play alone or with friends. When fans worried about the game&#8217;s direction in 2025, the studio wrote that nothing had changed: it would stay single-player first, with optional co-op and &#8220;no subscriptions&#8221;.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-thumbnail aligncenter wp-image-24760\" src=\"https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-tadpole-orange-water-800x450-1.webp\" alt=\"A Tadpole submersible glides through hazy orange water in Subnautica 2\" width=\"800\" height=\"450\" srcset=\"https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-tadpole-orange-water-800x450-1.webp 800w, https:\/\/igamemag.com\/wp-content\/uploads\/2026\/10\/subnautica-2-tadpole-orange-water-800x450-1-768x432.webp 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><\/p>\n<h2>What players are saying about Subnautica 2 co-op<\/h2>\n<p>Subnautica 2 is rated <strong>Very Positive<\/strong> on Steam overall (91% of more than 128,000 reviews), and recent reviews are still Very Positive at 82%.

Unknown Worlds hasn&#8217;t commented on the PDA pause or shared upgrades in its patch notes so far.<\/p>\n<h2>What&#8217;s next for Subnautica 2? Early Access 2<\/h2>\n<p>On <strong>15 October 2026<\/strong>, Unknown Worlds started a new dev vlog series called &#8220;The Voyage to Early Access 2 Begins&#8221;, setting up its next big content update. There&#8217;s no date for Early Access 2 yet. The studio says Early Access will run &#8220;over the next few years&#8221;, with regular free content updates and no paid DLC planned. It also expects the price to go up when the full game launches, and promises advance notice.<\/p>\n<p>Official mod support isn&#8217;t available in Early Access, although the studio &#8220;would like to consider&#8221; it later. Community mods do exist, and Unknown Worlds asks players to disable them after each hotfix until mod makers update them.<\/p>\n<h2>Subnautica 2 PC requirements<\/h2>\n<p>If you&#8217;re hosting, aim for the recommended specs, because your PC runs the world for everyone.<\/p>\n<table><tbody>\n<tr><td><\/td><td><strong>Minimum<\/strong><\/td><td><strong>Recommended<\/strong><\/td><\/tr>\n<tr><td><strong>OS<\/strong><\/td><td>Windows 10\/11 64-bit<\/td><td>Windows 11<\/td><\/tr>\n<tr><td><strong>Processor<\/strong><\/td><td>Intel Core i5-8400 \/ AMD Ryzen 5 2600<\/td><td>Intel Core i7-13700 \/ AMD Ryzen 7 7700X<\/td><\/tr>\n<tr><td><strong>Memory<\/strong><\/td><td>12GB RAM<\/td><td>16GB RAM<\/td><\/tr>\n<tr><td><strong>Graphics<\/strong><\/td><td>GTX 1660 6GB \/ RX 5500 XT 6GB<\/td><td>RTX 3070 8GB \/ RX 6700 XT 8GB<\/td><\/tr>\n<tr><td><strong>DirectX<\/strong><\/td><td>12<\/td><td>12<\/td><\/tr>\n<tr><td><strong>Storage<\/strong><\/td><td>50GB<\/td><td>50GB<\/td><\/tr>\n<\/tbody><\/table>\n<h2>More co-op survival games on iGame Magazine<\/h2>\n<ul>\n<li><a href=\"https:\/\/igamemag.com\/en-gb\/once-human-isles-of-abyss-release-date\/\">Once Human: Isles of Abyss<\/a> \u2013 another ocean survival adventure, with ship building and diving<\/li>\n<li><a href=\"https:\/\/igamemag.com\/en-gb\/windrose-guide\/\">Windrose guide<\/a> \u2013 co-op survival at sea for up to eight players<\/li>\n<li><a href=\"https:\/\/igamemag.com\/en-gb\/enshrouded-1-0-release\/\">Enshrouded 1.0 release<\/a> \u2013 the co-op survival hit just left Early Access<\/li>\n<li><a href=\"https:\/\/igamemag.com\/en-gb\/abiotic-factor-roadmap-year-2\/\">Abiotic Factor Year 2 roadmap<\/a> \u2013 what&#8217;s next for another co-op survival favourite<\/li>\n<\/ul>\n<h2>Subnautica 2 multiplayer FAQ<\/h2>\n<h4>Does Subnautica 2 have multiplayer?<\/h4>\n<p>Yes.
