If you’ve spent hours scrambling for oxygen while evading reaper leviathans in the original Subnautica, you’re probably just as hyped for the sequel as I am. I’ve been following Subnautica 2’s development for two years, and got access to the playable build the second it dropped for the public. The first question most players ask when new info drops is is Subnautica 2 in early access, and what that means for anyone looking to dive in right now. Early access games can be a gamble, especially for franchises with such a loyal fanbase, so I put together this guide to break down exactly what you can expect if you pick it up today.
Is Subnautica 2 in Early Access? The Short Answer
Yes, Subnautica 2 officially launched in early access earlier this year, with developers stating they plan to keep it in active development for roughly 18 months before the full 1.0 release. That timeline could shift based on community feedback and unexpected development hurdles, but the team has stuck to their announced update schedule so far. If you’ve asked is Subnautica 2 in early access because you don’t want to pay for an incomplete game, that’s a totally valid concern. The early access build currently includes 3 of the 5 planned biomes, and roughly 40% of the full game’s main story, so you’re getting a solid chunk of content for the price.
It’s not a perfect experience, of course. You will run into occasional bugs, missing features, and unfinished story beats that end abruptly. But the core survival gameplay that made the original so iconic is fully intact, and even with its rough edges, I’ve had more fun with this early access build than I’ve had with most full-release survival games in the last year.
What You Can Actually Play in the Current Early Access Build
You don’t have to worry about paying for a barely playable demo here. The team made a conscious choice to hold off on the early access launch until the core loop was fully functional, so you can sink dozens of hours into the game right now without hitting a game-breaking wall. For anyone wondering is Subnautica 2 in early access worth playing for the base building alone, the answer is a resounding yes. The new build system is way more flexible than the original, with tons of new pieces to customize your underwater home.
Here’s a quick breakdown of all content that’s fully functional as of the latest update:
- Full base building system with 20+ buildable pieces, including underwater glass domes and power generators that run on thermal or bio fuel
- 12 unique hostile and passive creatures, each with their own behavior patterns that change based on time of day and your proximity to their nests
- Side quest system with 17 available quests that unlock new crafting recipes and lore about the planet’s previous human inhabitants
- Cross-save support between PC and console versions of the early access build
The three available biomes are all massive, with tons of hidden caves and secret areas to explore. I spent 12 hours just poking around the Glow Reef before I even touched the main story quests. If you’re only interested in playing a fully polished, complete story, you’ll want to wait for the full release. The current main story cuts off right after a major plot twist, so you’ll be left hanging until the next major content update drops.
Common Issues to Watch for When Playing Subnautica 2 Early Access
Most players who ask is Subnautica 2 in early access also want to know how stable the build is, and the answer varies based on your platform. I played on both PC and PS5, and the PS5 version is noticeably more stable, with far fewer crashes than the PC build. That said, both versions are perfectly playable as long as you know what to watch out for.
The most common issue I ran into was save corruption if I quit the game while I was inside a submarine or sea truck. I lost 8 hours of progress once because I exited right after parking my truck in a new biome, so always make a manual save before exiting, and store a backup save file if you’re playing on PC. You’ll also notice occasional pathing bugs with larger creatures, like leviathans clipping through cliff walls or floating in mid-air. It doesn’t break the game, but it can kill the immersion pretty quickly.
Performance drops are also common in the Abyssal Trench biome, even on high-end PCs, when there are dozens of bioluminescent creatures on screen at once. Turning down shadow quality fixed that issue for me 90% of the time, so that’s the first tweak I recommend making if you run into frame rate issues. Devs push out small bug fix updates every 2 weeks, and major content updates every 3 months, so most of these issues will be resolved as development progresses.
Is Subnautica 2 Early Access Worth Buying Right Now?
This depends entirely on what you’re looking for out of the game. If you’re a diehard Subnautica fan who loves testing new content, sharing feedback with devs, and don’t mind occasional bugs, it’s absolutely worth picking up today. The core gameplay is just as tense and rewarding as the original, and the new biomes and creatures feel fresh without straying from what made the first game so beloved. You also get to influence the final game, as the dev team regularly polls players on what features they want to see added next.
If you’re a casual player who only plays fully finished games, hates dealing with crashes, or wants to experience the full story without waiting for updates, you’re better off waiting for the 1.0 release. The current story is incomplete, and there’s no multiplayer option yet, so if you were hoping to play with friends, you’ll be waiting at least 6 more months for that feature to drop.
The early access price is 20% lower than the planned full release price, so you’ll save money if you buy in early. If you do pick it up, I recommend joining the official community Discord to share feedback and get real-time updates on patch notes. The devs are extremely active there, and they’ve already added several community-requested features, like the ability to rename your base and adjust oxygen tank capacity in custom game modes.
At the end of the day, the answer to is Subnautica 2 in early access is a clear yes, and it's a surprisingly polished experience for how early it is in development. You don’t have to rush to buy it if you prefer finished games, but if you’re craving more tense underwater survival fun, you won’t regret picking it up. I’ll be updating this guide every time a new content patch drops, so check back later for more info on new biomes, bug fixes, and feature additions as they roll out.
