Subnautica is a video game about underwater exploration in an open world. It's an adventure game that's being developed by the independent developer that also made Natural Selection 2. The game throws you into an alien ocean world. You crashed, and you can only go down, deeper into the mysterious waters of this strange planet. Subnautica has many different ocean environments, from sun-drenched coral reefs to dangerous deep-sea trenches. You will need to keep an eye on your oxygen supply as there's lots of exploring to be done. Kelp Forests, plateaus, reefs, and complex cave systems are all available for exploration, just make sure you know how to approach the creatures that you find there, as some may be more hostile than others. In Subnautica you need to find water and food to survive, but you must also develop your equipment so you can explore. The ocean around you can be hostile, but it is also a vast place full of useful resources. Craft various items such as knives, diving gear, lights, and even make your very own watercraft. Crafting more advanced items is only possible if you go deeper down to find rarer resources, which are needed for these items. Subnautica also allows you to build a base on the sea floor. The player is given full control over the layouts and components used, but managing hull integrity as depth and the preassure increase will also be important. Your base can be used as a storage for resources, vehicles, and it's the place where you will resupply yourself with oxygen. Come face to face with deadly underwater predators which will show you how it feels to be on the bottom of the food chain. These sea beasts can be distracted with a fresh fish if you get tired of running away from them. When you decide to explore extreme depths, you will need to build yourself a Pressure Re-Active Waterproof Nanosuit, or PRAWN Suit. The suit can then be equipped with mining drills, torpedo launchers, propulsion cannons, and even grappling hooks. Just be careful when night comes, as the predators come with it. The ocean definitely looks mesmerizing at night, but it also becomes full of really nasty, big fish. Cave systems will allow you to explore the world below the ocean floor, but keep track of your oxygen levels, you wouldn't want to start losing your breath in a dark, claustrophobic passage now, would you?

The very first hour spent in this game, firmly and uncompromisingly passed the verdict - I love her. Not an intrusive plot, a huge open world consisting of many beautiful and creepy biomes, a perfectly built gameplay basis. I recommend this game, although it is for an amateur. Not many will love this pacifist genre and passive creative gameplay.
