If you’ve spent dozens of hours scanning alien fish, building underwater bases, and escaping the shadow of leviathans on Planet 4546B, you’re probably one of millions of fans asking when is Subnautica 2 early access coming out. The original Subnautica and its standalone sequel Below Zero set a new bar for open-world underwater survival, blending tense exploration, heart-pounding horror, and surprisingly heartfelt story beats that stuck with players long after they beat the final mission. We’ve scoured every official developer update, interview, and playtest leak to pull together all the confirmed information you need about the upcoming game’s early access launch, plus what you can expect to play when it drops.
When Is Subnautica 2 Early Access Coming Out? Confirmed Launch Details
As of the latest official update from Unknown Worlds Entertainment, the studio behind the entire Subnautica franchise, Subnautica 2 early access is targeted to launch in the second half of 2025. That timeline was shared during a developer Q&A posted to the studio’s official Discord channel in March 2024, where the team noted they were prioritizing polish over a rushed launch to avoid the bug-ridden early access releases that have frustrated fans of other survival games lately. There is no exact specific day or month confirmed yet, but the studio has committed to sharing monthly progress updates starting in Q4 2024, so fans will get plenty of advance notice before early access goes live.
It’s also worth noting that the early access release will be exclusive to PC first, with console launches coming 6 to 12 months after the full 1.0 release, per the studio’s standard release pattern for past Subnautica titles. If you’re planning to play on PlayStation or Xbox, you’ll likely have to wait a bit longer than PC players to get your hands on the new game. The team has also confirmed that early access will be available on both Steam and Epic Games Store at launch, with cross-play support between the two storefronts for co-op gameplay.
Confirmed Features Coming to Subnautica 2 Early Access
One of the biggest questions fans have beyond release timing is what exactly will be included in the early access build, since not all planned features are usually available at launch. Unknown Worlds has shared a handful of confirmed features that will be playable from day one of early access, so you know what to expect when you jump into the new alien ocean:
- An entirely new frozen ocean planet separate from 4546B, with biomes ranging from sunlit shallow coral reefs to pitch-black frozen underwater cave systems home to never-before-seen leviathan class creatures
- Full 4-player cooperative multiplayer, a first for the Subnautica franchise, that lets you build bases, explore, and complete story missions with friends, with both public and private server options
- Revamped base building mechanics that let you build floating surface structures, underwater habitats with dynamic pressure systems, and even mobile bases that you can pilot across the ocean to explore new biomes
- A full first act of the main story campaign, with roughly 15 to 20 hours of playable narrative content that will expand with each early access update over the 12 to 18 month development window
The studio has also noted that some features, like endgame story content, advanced crafting tiers, and a handful of planned biomes, will be added gradually over the early access period. You won’t be able to complete the full story at early access launch, but the team has promised that the content available at launch will feel complete and polished, not like a half-finished demo. Many fans are most excited about the co-op feature, which has been the most requested addition to the franchise for over 7 years now. Testing for co-op began in late 2023 with a small group of closed playtesters, and feedback so far has been overwhelmingly positive, according to developer updates.
What We Know About Subnautica 2’s Story So Far
If you’re a long time Subnautica fan, you know the franchise’s story is just as big of a draw as its exploration and survival gameplay. The new game is set roughly 10 years after the events of Below Zero, and follows a team of Alterra researchers sent to investigate a newly discovered ocean planet that is showing signs of ancient alien life. You’ll play as a new protagonist, not Ryley Robinson or Robin Goodall from the previous two games, though there will be small Easter eggs and references to past characters for long time fans to find.
The core story will focus on the mystery of why the planet’s ocean is rapidly freezing over, and what happened to the previous Alterra expedition that went missing on the planet 20 years before your arrival. The studio has teased that the story will have multiple endings for the first time in franchise history, with your choices throughout the campaign impacting how the final events play out. Don’t worry, you’ll still find plenty of familiar survival mechanics, like scanning creatures, managing your oxygen supply, and crafting gear to explore deeper and more dangerous biomes. The team has also said that the horror elements will be cranked up a bit compared to Below Zero, with more tense encounters with unknown creatures in dark, unexplored areas of the map.
Tips to Prepare for Subnautica 2 Early Access Launch
While we wait for the official early access launch date to be announced, there are a handful of small things you can do to get ready to jump in as soon as the game goes live. First, if you haven’t played the original Subnautica or Below Zero in a few years, it’s worth replaying to refresh your memory on the core mechanics and lore. You don’t need to play the past games to understand the story of Subnautica 2, but you’ll miss out on a lot of fun references if you don’t.
Make sure your PC meets the announced minimum system requirements, which the studio shared in early 2024: you’ll need at least 16GB of RAM, an NVIDIA GTX 1660 or equivalent GPU, and 50GB of free SSD storage to run the game on low settings at 1080p 30FPS. If you want to run the game on high settings with ray tracing enabled, you’ll need a more powerful GPU like an RTX 3070 or equivalent. You can also join the official Subnautica Discord server to get real time updates from the dev team, and potentially sign up for future closed playtests before early access launches.
If you plan to play co-op with friends, now is a good time to coordinate who will be in your group, and even set up a shared server if you want to host your own game when it launches. Avoid pre-ordering the game if you’re on the fence, as the studio has confirmed there will be no pre-order exclusive content that you can’t get by buying the game after early access launches. You should also watch out for fake release date scams on social media, as scammers often take advantage of high anticipation for popular games to trick fans into clicking malicious links or buying fake keys.
At the end of the day, we’re all just as excited as you are to get our hands on the next chapter of the Subnautica franchise, and we’ll update this post as soon as we get any new information about when is Subnautica 2 early access coming out. The studio’s focus on polish and player feedback during the development process means we’re likely getting the best Subnautica game yet when early access drops, and the addition of co-op alone makes it worth the wait. Just remember to be patient, stick to official developer channels for the latest accurate updates, and get ready to dive into a whole new alien ocean soon.
