The early access Subnautica 2 roadmap gives you a look at what Unknown Worlds is cooking up for its survival game sequel. As we get ever close to the big update 2.0, there's still loads to enjoy from earlier in EA, including prox chat, oxygen sharing, and emotes. There's been a little less for the solo players out there, but EA 2.0 is going to keep both squads and singles very happy. There are still no dates or timelines on the rest of the roadmap, but we do have an official window of when the next Subnautica 2 update hits, so here's a look at what's to come.
Subnautica 2 EA 2.0 release date window and details
Now that Subnautica 2 early access updates 1.1 and 1.2 have come and gone, we're looking into the 'Future' of the official roadmap, where some of the most exciting additions and changes are waiting to be released.
From the list of future updates, the likes of a new vehicle, new creatures, new biomes, and more have all been confirmed in a recent dev vlog, and I've got more on that in my more detailed guide to the next Subnautica 2 update, which is set to be released in December 2026. It's the biggest update by far, and is going to change the game quite literally.
While that's just the start of what's to come for Subnautica 2 in the EA 2.0 update, here's a brief overview of everything that has been added so far:
Subnautica 2 Buddy System Update (1.2)
Subnautica 2 update 1.2. known as the Buddy System update launched on August 19, 2026, with the headline additions being cross-platform proximity chat, player reviving, emotes, and trading between players.
You can also play as two new characters, Jegna and Grace, and there have also been some community-suggested changes to the HUD and the Subnautica 2 Habitat Builder tool, along with many other tweaks and fixes for the game.
Subnautica 2 Adaptive Measures Update (1.1)
Early Access update 1.1, AKA Adaptive Measures, was released on July 8, 2026, and focused on changes to creature behaviour. Not only can you now more easily assess (and scan) creatures after hitting them with a tool, you can also stun them with the Subnautica 2 Sonic Resonator tool. There are also new biomods, storage updates, and UI upgrades.
In the meantime, we can help guide you through everything that's already available in early access, including how to get a Subnautica 2 tadpole for easier exploration, how to craft Subnautica 2 ingots, and how to make the most of Subnautica 2 console commands.
