Subnautica is an open world, underwater exploration and adventure game currently under construction at Unknown Worlds, the independent developer behind Natural Selection 2. After crash landing on an alien ocean world, the only way to go is down. Subnautica's oceans range from sun drenched shallow coral reefs to treacherous deep-sea trenches.
Manage your oxygen supply as you explore Kelp Forests, plateaus, reefs, and winding cave systems. The water teems with life: Some of it helpful, much of it harmful.
Subnautica is hands down the best survival game I have ever experienced. I completely lost track of time while playing it and for the first time in ages I rescheduled my appointments and neglected my responsibilities to spend more time with a game. If I could I would hand out free copies in the streets so as many people as possible can see how ridiculously good Subnautica is. [04/2018, p.62]
It isn’t without performance hiccups, especially the deeper you go. But the breadth of content here and the open-world nature both in terms of playspace and just pure choice in how you go about it is something rarely seen in games.
Subnautica is an exceptional game of exploration, crash-landing the player on an unknown planet with unfamiliar terrain, unexplored depths, and strange wildlife. While some smaller creatures will appear more afraid of you, it's the larger predators that will make your oxygen levels quickly drop with the increased heart rate. It's a game that captivates you as soon as you step out of the lifeboat with the gorgeous water effects and stunning environment.
Subnautica is an atmospheric, wonderful survival game full of surprises. You never know what to expect every time you dive in the depths of the ocean.
For those determined enough, though, this is a survival game like no other. [March 2018, p.80]
Subnautica shows an almost perfect mix of survival, exploration and building. The story is so beautifully woven into the game, without being forced on the player.
Subnautica is a very, very, very good game for fans of the survival genre. There is a near endless deluge of things to do and see and a vast, dangerous ocean to explore. It’s not uncommon to alternate between sheer dread and speechless wonder as you make your through this underwater wonderland. However, lackluster VR support and an overall density problem in terms of complexity and lack of direction at times hold Subnautica back from true greatness.
