I bought this game thinking it was a peaceful underwater exploration game. 🌊 First 10 minutes: β€œWow, beautiful fish, coral reefs, relaxing music.” 30 minutes later: WHAT WAS THAT SOUND 1 hour later: I hear a distant roar. The water turns dark. Something large moves in the distance. Then I meet the love of my life: Reaper Leviathan This creature’s hobbies include: screaming directly into your soul grabbing your submarine giving you permanent psychological trauma Meanwhile the game expects you to calmly build a base while your brain is screaming: β€œTHERE IS A 50 METER DEMON FISH SOMEWHERE IN THIS OCEAN.” Also oxygen is apparently optional until it isn’t. Nothing compares to the panic of: OXYGEN: 10… 9… 8… while you’re stuck in a cave like an idiot. Pros: beautiful ocean world incredible exploration terrifying sea monsters Cons: I am now scared of the ocean I hear Leviathan noises in my sleep 10/10 Would willingly crash on Planet 4546B again. 🌊

I've been playing this game for years, on a variety of platforms. I recently purchased it again on Steam, so it's about time I left a review. This right here is one of the best survival games I've ever played, which is surprising, as I usually stray away from single player survival games because there is no social aspect involved for them to keep my attention. However, in the case of Subnautica, the "lonely" and isolated aspects are part of the reason I love it so much. It is really immersive and illustrates the feeling of being stranded by yourself, in an alien planet, perfectly. There is really no way to describe being at the bottom of the ocean, nothing but pitch black around you, and then seeing the silhouette of a giant sea creature in the distance. It really rattled my bones the first few times I had to make my way to the Aurora. Graphics are great, considering that it is a game from 2018. Incredibly optimized, and I can run it with ease even on my Steam Deck. On the other hand, something that really impressed me was the detail and attention that went into the sound design. The soundtrack and general eeriness of the underwater sounds make this one of the most immersive games I've ever played (headphones recommended). The progression system is also extremely satisfying, and at no point did I feel that the crafting was too tedious or overwhelming. You can literally play for hours and not get bored, only problem being that good things come to an end (expect 30-40 hours). I honestly wish that I could wipe my memory of this game, just so that I can experience it blindly once again! Overall, this is definitely one of my favorite games of all time, with one of the most interesting concepts I've ever seen. I would give it a 9.5/10

This game literally changed my life, it changed the way I view the worlds beauty and gave me a deeper interest in marine life. I'll never forget my first play-through. I can't recommend Subnautica enough, the world building and story telling are amazing, it really makes you feel like you're living on 4546b. The balance of wanting to beat the game and never wanting it to be over because you fall in love with the world is a feeling I don't think will ever be recreated for me quite the same way. I've been playing this game for years and it still hasn't lost it touch even after all this time. You'll enjoy this game for it's game play and mechanics, but you'll fall in love with it for it's rich story, amazing ecosystems, captivating wildlife, and deep world-building. I recommend playing this game not for the ending (though it is amazing) but for the journey there, take your time, explore every nook cranny and tiny cave, listen to the PDA entries, scan the wildlife and read about how they live, build not just a house or a base but a home, look for easter eggs, and dive into every wonder-filled biome no matter how deep and dark. You will be rewarded. It's unique charm is everywhere you look and it's worth every second and penny you spend on it. I could go on and on about how much I love this game but I think it's better you play it for yourself. It isn't without a bug or flaw here and there, like sometimes the fauna and vehicles can clip through the floor, and I wish there was a way to customize the inside of the cyclops color or the outside of your bases more, and if you could dock your cyclops somehow so it didn't just sit next to your base without much of a true home I would love that, perhaps the sequel can add a larger moon bay. And I'd love more ways to make inventory management easier, like an expandable bag of some kind or simply the sea-glide only taking 4 slots would be great too. But those are really my only nit-picks, this game is amazing and I can't thank the devs enough for making it. I'm beyond excited for Subnautica 2 to release. This game competes with Minecraft, Breath of the wild, and Pokemon for the title of my favorite game. Yet when someone asks me what my favorite game is, Subnautica always comes to mind first. Just play it, it's a 10/10.
