About
Subnautica 2 is an underwater survival adventure game set on an all-new alien world. It is the next chapter in the Subnautica universe, developed by Unknown Worlds.
Driven from your home by ongoing conflict, Alterra offers you the chance at a new life. But as the colony ship CICADA shepherds you and your fellow Pioneers to your new home, something goes awry. The ship’s AI insists that your mission should continue. Stranded and faced with near-insurmountable odds, you must do everything in your power to survive. The future of humanity on this world is in your hands.
Subnautica 2 is being crafted as a single-player experience that you can optionally play in online co-operative multiplayer with up to three friends. You can choose from four pre-designed characters, with more characters and customization options coming throughout Early Access. Work together to explore long-forgotten ruins and learn to adapt to a planet that might not want you there.
To survive the depths and make this planet your home, you’ll need to utilize all the tools at your disposal. Traverse vibrant and breathtaking biomes with your Tadpole submersible. Design and customize bases to return to when your adventures push you beyond the safety of shallow waters. As Early Access develops, so too will your array of tools, equipment, and vehicles. Upgrades will help push you beyond your boundaries and unlock the secrets of this strange world.
Scan and study a rich world of biodiversity to understand life here. Discover everything from the smallest creatures to towering Leviathans. Experience the wonder, and sometimes danger, lurking around every corner. Every dive is an opportunity to uncover why the ship's AI is so determined to continue the mission and what mysteries lie beneath the surface of this breathtaking new frontier.
Subnautica 2 is an Early Access title in active development. Throughout this journey, we will continuously expand the world with additional biomes, creatures, and craftables, while expanding the narrative. You may encounter bugs, in-development features, and performance issues. Your feedback is the cornerstone of our development process. Join us and help shape the next chapter of the Subnautica universe.
Subnautica 2 is being developed by Unknown Worlds, the studio behind the award-winning Subnautica and Subnautica: Below Zero. Our journey began with the 2003 Half-Life mod Natural Selection, and today we have evolved into a fully remote, globally distributed team spanning from the United States to the United Kingdom, France, Australia, and beyond. Defined by a philosophy of open development and over a decade of community-focused innovation, we invite you to dive back into the depths with a studio dedicated to pushing the boundaries of the survival genre.

Very well polished for early access, base building is far more extensive, customizable and fun compared to the original game. The multiplayer aspect doesn't remove the fear and terror of the unkown and the feeling of isolation on an alien planet. A worthy sucessor all in all.
Whilst I would recommend this game to others, you are looking at around 6-7 hours worth of story gameplay. I was playing co-op with my wife and we scanned explored and did all of it within about 10 but kept playing for a few more just to make our base bigger. £50 for 2 people and replayability being minimal at this point I would suggest awaiting for bigger updates or the game goes on sale for around £15 as £50 for 2 people is a bit much. However other than my wife swimming in 1 section of our home when I was walking or the fish sometimes swimming through the base, I have no issues with this at all. Solid connection, no booting or lag. All in all a good game just a little pricey for what it is now.
After completing the early access part of the game, I was left extremely happy for what may come later. The base game was already great enough given all of the story behind it, and you can partially see a similar story rising up like the original Subnautica. That's amazing. And it's a huge upgrade from BZ. The graphics on ultra are incredible. I've played it on 3 different computers (albeit, most of them midrange-highend, so the lag was never really an issue) and found the vibrancy incredible. The gameplay was quite fun, and I really like the direction this early access preview has implied this game will be heading in. Some of the glitches are hilarious. I honestly think they should remain in the game as long as they don't destroy gameplay as a whole just for the memes. I had an awesome time with some of my friends figuring these out, and playing around with them. We all had a good laugh at them. Now, let's be honest here. There are definitely things that need to be worked on. Most notably, the vehicles, the fauna, and the wakemaker. I have absolutely no clue if this is still true today, but it seems that the tadpole will be the only vehicle released for this game. Have we not learned from Below Zero here? People don't like the idea of modules where you turn your supposed "Fast scouting vehicle" into a hauling vehicle. It defeats the purpose, and only makes you have to use double the resources to have 2 that actually serve independent purposes. The fauna are either incredibly easy to avoid, are a pain in the ass, or are literally unavoidable for some odd reason. This classification is NOT based on the type of fauna it is. Sometimes, the collector leviathan will just ♥♥♥♥ off, and other times, doing the exact same thing, it eats you and the following bloodline of reprints 8 times over, simultaneously destroying 3 of your tadpoles. A nibbler mango will sometimes just swim around you and never attack you, or it can be a sneaky bastard that decides its your time. I don't like the inconsistency. It makes every interaction with any fauna a gamble in an unnecessary fashion. The wakemaker is definitely where I get the most irritated. You don't get a significant, or even NOTABLE boost in speed using it without glitches. Early game progression is curbstomped so hard in this game because of this thing to the point its almost laughable. It was an absolute hellhole trying to get resources without proper equipment like a tadpole or nearby base to rely on for oxygen without straying too far to where it becomes inefficient for you to gather resources there without them. Lithium, Gold, and Silver especially, are extremely notable for that. Now, it's definitely still an amazing game. These are just nitpicks that I seem to have with the game. And I'm glad these were discovered quickly by others in early access so that we don't get left with a game like BZ, where we don't get the content we want at all. It's going to be an interesting experience seeing this game eventually release with whatever they decide to come up with, and I hope the Unknown Worlds development team will listen to community feedback.

it is fun
good
good game but ♥♥♥♥♥♥♥ runs like ♥♥♥♥
amazing game
从美丽水世界,是的那时候还叫这个名字,是我曾经最喜欢的游戏,没有之一。然后你搬出了zero,一坨没有优化,早期版本的屎,我全款买的结果大失所望。终于我等来了2,我看到了啥,就开了个珊瑚区和一个外星区,没啦?18小时通关啦? 开发者还记得一代的时候,下潜到深水区,第一次看见暗河下的生命树吗?我当时截图了,11年前那场景壮美得让人想哭,我觉得是开发者为游戏人写得诗。 但现在……高重复,内容不够硬塞25人得时间线让人化身福尔摩斯去猜,地图没更完就塞大白鲨和大鱿鱼守着,甚至你连世界树都不让我上。 刚玩的时候我刚大学毕业,现在我是孩子的父亲,11年,我的人生有几个11年要等? 下回不会做菜,就别端上桌。
