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.

huge fan of subnautica and below zero, but #2 has a long long way to go before its worth paying for. why ruin it buying it now only to play 1/20th of what the full game should be - just ruins that "first dive" experience . glad I immediately returned it , I will check back in 2-5 years
This is what we waited for?
Invincible fish is stupid asf. Not only does it not make sense from a lore standpoint when you're simultaneously harvesting innocent filter fish for a few oz of air or grilling other fish for meat, smashing up coral reefs for battery acid, etc... but for some reason you can't fashion yourself even a knife to defend yourself from real, lethal and near-constant threats. This is especially stupid given the leviathan class monsters always trying to eat your a$$... Additionally, this introduces a whole host of stupid mechanical issues such as predators around bases being unable to be removed or dealt with accordingly, constantly attacking your vehicles, etc. This isn't Earth ffs. It's a video game. This feature, by the way, does nothing but further reinforce the artificial reality of this world, rather than help the player immerse themselves in actual escapism. Sadly, this is not an early access issue, it's a design philosophy. While I also appreciate protecting our oceans and the idea behind harmony in nature - the hypocrisy of the features presented in this game do not really make sense. You're still destroying marine life. Just... some marine life is okay I guess? You know, when you need food, air or crafting materials. Just, like... not when you're facing imminent death by an aggressor. Yeah ok.
못때리는게 아쉬움
为了呼吁动保不让攻击鱼类但却能抓小鱼生吃和烤着吃，制作组不觉得矛盾吗？
ok game would rate it very high if it had guns,weapons. this company is anti guns no guns. because of this i quite playing . other than that it was a fun game i thought graphics was really good .
还我蝌蚪号。不让探索的区域放一堆怪物，把蝌蚪号断送在里面了，用尽所有力气依然无法重新拯救蝌蚪号，希望后续改进这一点，助力蝌蚪号回家。改进之前是不打算继续玩了。

Pretty boring. Doesn't really improve much on the first game. Would not recommend.
Cannot attack the enemies attacking you. Seriously
