“A very interesting and fun game, especially with friends. The story is not amazing, but it's not bad either. Quite the rare sea experience we really don't have in many other games. Big credits also goes to some of the…”

“Subnautica isn’t just a survival crafting game—it’s an unforgettable experience that completely redefines what the genre can be. From the moment you crash into its vast alien ocean, it pulls you in with a sense of…”
“It’s no surprise this game won the ‘Best Survival Game’ award in 2018. To this day, it still remains the best survival game available. Yes, even in 2026, the game still plays incredibly well. Beautiful game, amazing…”

“IDK what it is about this game. Can't play it for just an hour. Nope I start playing and suddenly it's tomorrow. I guess what hooks me is how rewarding progression is. I also like it better than SubZero because the…”
“Very few survival crafting games can come close to the sheer surprise that Subnautica can offer. At a surface level observation, it is simply a deep sea diving and crafting game, with a very clear and direct problem:…”

“One of the most outstanding games that I have ever played. Just enough open-world to amaze you with discoveries but just enough quest-like progression to keep the game on the rails. Superb.”

“A great game, my only complaints would be the lore's a bit boring and at times it can be hard to know exactly what to do. Nevertheless the gameplay was addicting and highly immersive. 8.25/10”
“A truly fantastic exploration survival game. The survival mechanics feel tedious at first, but once you get a hang of things, really become secondary... until you get lost exploring and forget to bring backup O2. The…”
“[h1]So Much Ocean, So Much to Discover[/h1] Subnautica is one of those games I wish I played earlier. I’d been meaning to try it for a long time, and once I finally did, I got hooked pretty fast. The world is completely…”

“great game, i love how its so beginner friendly as you can find loot caches at the back of the large spaceship and at the very edge of the maps. If you are having trouble progressing just go in a random direction until it says you have entered the ecological death zone (this…”

And in the spirit of keeping this review vague so others may experience what I did, all I will say is that this game is one of a kind. I yearn for games like this set in alien oceans. The base building…”
