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.

Reviews
A great cooperative experience, but base building space is a big issue I think Subnautica 2 made a great decision by adding cooperative gameplay. Playing with friends or family members is a really enjoyable experience and adds a completely new way to enjoy the Subnautica universe. I also like that the story keeps the classic Subnautica feeling. The adventure, exploration, and mystery are still there, and it feels like the developers are respecting the traditions of the series. The new sleeping mechanic is a nice addition too. When one player rests, their character is not consuming food or water resources, which makes multiplayer sessions more convenient. However, there are some disappointing things. The biggest problem for me is the limited space for building a base. Many areas feel too small, filled with coral, creatures, or other objects. The best locations are often already occupied by fish, species, or pieces of wreckage, leaving very little room to create a proper base like in the previous Subnautica games. Another issue is that some mechanics are not explained well. For example, the resonator and ways to protect yourself from dangerous creatures are not very clear. Sometimes it feels like you have no real options when dealing with threats. The limited building space is my biggest dealbreaker because base construction was one of the most enjoyable parts of Subnautica for me. I hope future updates add more open areas where players can freely build larger bases. Despite these problems, I still purchased the game at full price because I believe the Subnautica series deserves it. The exploration, atmosphere, and adventure are still worth experiencing.

good game
"Varlık İçinde Yokluk Simülatörü" Oyuna başladım, ekranda beliren metin aynen şu: "20.000 yıl boyunca buraya kimse gelemez, kendi uygarlığınızı kurun." Işık hızını aşmışız, dark matter iyon sürücümüz var, faz kapısı inşa ediyoruz... Ama Subnautica evreninde olduğumuz için teknoloji seviyem ne olursa olsun kaderim değişmiyor: Medeniyet Seviyemiz: Galaksiler arası seyahat. Sahip Olduğum Silah: Ellerim ve agam. Acil İhtiyaç: hamsi tava. Abi adamlar uzayın en ücra köşesindeki gezegene fırlatmış bizi, yanda agamı domaltmışlar, arkada Kraken gelip benim @mıma koyuyor. İşin komik tarafı oyun başında kolayca bulduğum malzemeleri oyun sonunda bulamıyor oluşum amk. Bir de envanter kapasitesi koymuşlar; koskoca Uzay Gemisi mühendisiyim ama cebime 3 tane bakır 1 titanyum koyunca "Envanter Doygunluğuna Ulaşıldı" diye uyarı alıyorum. Adamlarda uzay gemisi yapacak teknoloji var ama sırt çantası falan yapacak teknoloji yok amk. Dip Not: 20.000 yıl sonra o mavi daire buraya temas ettiğinde kurtarma gemisini ben karşılayacağım. Kendi muhtarlığımı kurdum, agamı köleleştirdim benim için yaşıyor artık sabah akşam balık yiyoruz nerede o döner kebap falan. Oyun 10/10 ama yapımcıların emeğini sikm.
very fun
