About Subnautica:
Subnautica is an open world survival game in development by Unknown Worlds Entertainment.
Subnautica allows the player to explore an aquatic alien planet by scuba diving and traveling in ,
while collecting resources and food to survive. It was released on Steam Early Access on December 16, 2014.
The Xbox release was in August 2016.
The player controls in first-person view the lone survivor of a crashed ship on an aquatic planet.
The main objective of the player is to explore the open world environment and survive the dangers of the planet, while also continuing the story.
Subnautica allows the player to collect resources, construct tools, bases, and submersibles, and interact with the planet's wildlife.
Players must keep themselves adequately hydrated and fed, and must also maintain their oxygen supply while traversing underwater.
They disvocer remnants of the Precursors, an anchient alien species, that used to live on the planet, massive structures and recieve mysterious signals by a strange entity.
The development team opted to use the Unity engine rather than Spark, the engine used for the company's previous game,
Natural Selection 2. Subnautica producer Hugh Jeremy justified this decision because of the different demands that the game places on the engine,
and "because [the team] does not include people working on Spark, it's not appropriate for Subnautica to use Spark. By using Unity for Subnautica,
Spark can continue to develop in certain directions, while Subnautica develops in others. To use Spark for Subnautica would be to try and square peg a round hole."
Subnautica was released on Steam Early Access on December 16, 2014.
Subnautica was originally planned to be released on Xbox One on April 1, 2016, but was ultimately delayed by another month.
