I have ridiculously fond memories of Subnautica. Mark 'Markiplier' Fishbach and Seán 'Jacksepticeye' McLoughlin's playthroughs remain some of my all-time favorite pieces of gaming content, enhanced by the fact developer-publisher Unknown Worlds Entertainment cooked with the gas on full. The Subnautica 2 pre-release content cycle has really ramped up in recent months, and now is the perfect time to delve into the hit survival game series if you haven't already. 'Why is that?', you may ask. Well, starting today, you'll be able to play Subnautica for free all weekend long, and both the OG and its 2021 follow-up, Subnautica Below Zero, are getting some hefty discounts.

We have released a hotfix that addresses a security-related concern raised to us by Unity. You can read more about the specific issue here: https://unity.com/security/sept-2025-01/

While the update patches out the flaw, Unity has said that, to their knowledge, no one has exploited the issue to date, and no players have been at risk.

To help ensure that this security flaw can never be exploited on Subnautica or Below Zero, we have updated Unity following the guidelines provided. We have also had to make the difficult decision to disable all legacy and alternative branches of Subnautica and Below Zero, as there is no way for us to patch out the security issue on each of those branches individually.

If you play Subnautica or Below Zero with any mods on our legacy or alternative branches, you should disable or remove them before launching the game after the update to preserve your save files. You will need to check that the mods you want to play are updated to work with the most recent version of the game.

For our speedrunning community, this also means that the speedrunners branch has been disabled. We understand that this will affect speedruns moving forward, but the security and safety of all our players is our highest priority.

Thank you for all your continued support for Subnautica and Below Zero!

Keep Diving.

Not many of the experiences on the best survival games list capture the spirit of Subnautica, but some give it a good shot. Breathedge is like the series' wackier, less serious cousin, where instead of exploring an ocean, you're trapped in space and have limited oxygen. If you're looking for something to keep you occupied while you wait for Subnautica 2, you can get Breathedge and eight more survival games for just $12 with the latest Humble Bundle - and as far as I'm concerned, that is an absolute steal.

Subnautica 2 has become one of the year's most talked-about games, albeit for reasons I don't think anybody wanted. A big legal brouhaha has developed in the wake of publisher Krafton abruptly dismissing the entire leadership team of Subnautica 2's developer Unknown Worlds Entertainment...

We’re excited today to release a new patch for Subnautica! 

Thanks to some of the incredible development done on the mobile version of Subnautica, we were able to port that work across to other versions of the game.

This update will roll out worldwide and might take some time to appear across the globe.

Change Log

PC & Console

•
Added a pop-up newsfeed that can be used for one-time-only announcements.

•
Fixed an issue where passing through the Alien Arch portals (e.g. in the Primary Containment Facility) in your PRAWN suit freezes stats like oxygen or hunger, if you exited the suit.

•
Fixed the PRAWN suit sometimes falling through the map or getting stuck when the player returns from an Alien Arch portal.

•
Fixed Leviathans having a tendency to fly above the ocean surface when grabbing the Seamoth or PRAWN suit in certain cases.

•
Fixed having a permanent player view rotation offset upon respawning, if the player died while piloting the Scanner Room Camera Drone.

•
Fixed the game freezing if a player managed to construct a SeaBase piece inside of the Cyclops. It is now recognized as an obstacle for base building.

•
Fixed a bug where the Repulsion Cannon could displace objects built inside the Cyclops, causing them to fall outside of it and sometimes disappearing into the sea floor.

PC Only (Excluding Windows Store)

•
Changed from legacy Unity input to the new “com.unity.inputsystem” to accommodate controller improvements.

•
Fixed a bunch of controller related issues. 

•
Reworked input options. 

•
Various InputSystem related fixes and performance optimizations. 

•
The game now properly supports the following controllers in both wired and wireless modes: Xbox 360, Xbox Series, PS4, PS5, PS5 Edge, Nintendo Switch Pro.

•
Changed to the new Unity Sprite Atlas packer (backport from Below Zero).

•
Changed from baked InputSymbols.ttf to SDF sprites for displaying inline control icons in text. 

•
Updated control icons. 

•
Fixed game falling back to text representation of controls instead of control icons for some input bindings when no controller is connected.

•
Fixed navigation icons in PDA and Builder Menu not updating bindings dynamically when they change (e.g. when controller type changes).

•
Fixed an issue where the user cannot toggle the 'auto move' setting to On while cycling through Cyclops' cameras.

•
Made Cyclops steering wheel animations gamepad-friendly.

We haven't heard much about the upcoming Subnautica 2, apart from the devs reassuring fans that it won't be a live service game, so fans are understandably excited at the discovery of secret new screenshots of the sequel...

Product placement isn't quite as rife in videogames as it is in movies and TV, but there's still a long history of collaboration. Who can forget how Energizer used Alan Wake to let us know how quickly its batteries drained? Then there's League of Legends' long-running partnership with fashion company Louis Vuitton, which has spawned everything from ostentatious trophy carrying cases to in-game skins. Fortnite, meanwhile, has become a big playable billboard...

In response to concerns that arose after publisher Krafton said the upcoming Subnautica 2 will feature co-op mulitplayer built on the "games-as-a-service model," developer Unknown Worlds has clarified that it won't be very different from the early access releases of the previous games in the series, and that there will be no battle passes or subscriptions involved...
