Subnautica
Adventure
January 23, 2018
A sandbox game by Unknown Worlds that combines elements of action-adventure productions and RPGs. As the game’s universe draws inspiration from such novels as Twenty Thousand Leagues Under the Sea, at the bottom of the ocean you can find bizarre sea monsters, as well as remnants of futuristic buildings and ships. The player assumes the role of a captain of an advanced submarine, and explores the depths of the ocean. The game’s characteristic feature is the ability to design vessels and determine such things as performance, layout, on-board mechanisms, and materials used for the construction. You begin with rather primitive ships, but as you progress you will be able to construct more advanced vessels, and explore previously unavailable parts of the ocean. While playing, you can freely walk around your ship, and even go outside to explore the marine world on your own.
