Gameplay and Mechanics

Subnautica universe is just astonishing. Check out Subnautica: Below Zero via RoyalCDKeys

Subnautica is an incredible experience and a game loved by many, many people. Thanks to great design and enjoyable mechanics, every little water-world enthusiast and explorer is on the edge of their seat when imagining going back to this game.

And – you can do a lot here. From crafting, swimming to exploring and learning about the local flora and fauna – everything can be achieved if you have enough time on your hands. Subnautica: Below Zero is a pretty big game, so you can be sure that the time spent here will not be wasted!

Let’s check out the mechanics behind this game to see what really made it so popular.

We Need to Go Back! To Planet 4546B

Play Subnautica below Zero - it’s an experience like no other!

Our in-game sister is the main reason we needed to go back after the first part of the Subnautica story. Or, as we should probably say – her absence. The sister is missing, and you got a hunch that the deep levels of planet 4546B had something to do with it!

The Alterra corporation left this place in a hurry. Something definitely must have been wrong. What happened to everyone who lived here? Where are the logs? And once more – where in the world is Carmen Sandiego? Some things cannot be discovered, but some – definitely can! And you can be the one who unravels these secrets for the world!

Subnautica: Below Zero PC expands on the story told in the previous game and dives right into the sub-zero expedition mystery.

What Happened Under the Sea, Should Be Investigated Under the Sea

Subnautica: Below Zero is a new chapter in gaming

Subnautica: Below Zero is also a game of incredible wildlife. This scary planet really delivers when it comes to such simple things as – evolution.

So – swim under the blue expanses of Twisty Bridges, be astonished by the Crystal Caverns (spoiler – there are some pretty big crystals out there), and discover the peaks of the icy cave of Glacial Basin. Watch out for erupting Thermal Vents to find alien artifacts and, when there is time, your missing sister.

Also – don’t forget to greet the wildlife. Not everything wants to kill you. Well, Shadow Leviathan probably does, but the Pengwings are so cute! How can anyone hurt them!

Build Yourself a World!

Remember to craft and collect materials! You’ll need them to survive.

This planet is not the most welcoming place in the world. As you have probably guessed, you have to fight back many different life scenarios. Find the right resources and craft yourself some equipment.

There are many great ways to create new and interesting equipment for your Snowfox hoverbike or modular Seatruck. If you need a hand in creating something in the game, just consult it with the great community of Subnautica: Below Zero. Remember, the possibilities are endless when you party with friends!

It is also an open world to explore! There is no linear storyline to follow. You can go wherever you like, whenever you like. You want to go sightseeing – sure you can. You want to follow the main plot – there is this possibility as well!

It Still Going On!

The game is still being upgraded - check out what are the latest updates!

The game is still being upgraded, so expect the unexpected! You can check out the daily updates and get a glimpse of what the team is currently doing with the game.

The community is great and live, so remember – if you see something, say something! Especially when it comes to some great ideas you had and wanted to share with developers. They will gladly hear it; mark my words!

Subnautica was created by Unkown Worlds. It’s not a big developer focused on pumping out as many games as possible. Unknowns World is a studio of passionate people who just want to make the best game possible and enhance your experience to the maximum.



The game received mostly favorable reviews on Metacritic. Fans praised the graphics, feeling of the game, and incredible world-building. Some even say that it’s one of the best survival games in gaming history!

Many noted that the crafting system really allows you to experience the world. If you want to do something, you need to prepare it yourself. There are no shortcuts.

Devs from Unknown Worlds Entertainment always have something up their sleeve, so don’t sleep on this one!
