Subnautica is a thrilling first-person adventure game that takes you on a journey of survival in the deep sea. The game is developed by Unknown Worlds Entertainment and is available on the PlayStation 4 platform. As the protagonist Ryley Robinson, you have crash-landed on a planet that is entirely covered by an ocean. You must eat, drink, and manage your resources while discovering why your ship crashed.

The game provides a detailed plot that unfolds as you explore the ocean and uncover the remnants of other crashes. You will encounter dangerous creatures and learn about the mysterious Precursors. The game's environment is randomly generated, which adds to its replayability. Subnautica is well known for its spectacular portrayal of the ocean and its wildlife. The player can explore an underwater world full of corals, fish, and other colorful sea creatures, often grotesque or bio-luminescent. Robinson is equipped with scuba diving gear that allows the player to spend most of the game underwater, although oxygen still has to be replenished.
