Gameplay Protoypes Icon

Access to seven early development Prototype builds was sold within the earliest access campaign, selling the Subnautica Special Edition, which included other items such as the Special Hull Plate Upgrade and extra soundtracks.

Over the course of about one year Subnautica went through a number of Prototype builds. A lot of features were explored, like modular sub construction and base building. Also mechanics like dynamic lava, submarine ballast controls and more.

Notable is the change within the name from Descend to Subnautica.

Prototype #7 was lost at sea.

Eventually the Subnautica Terrain Test could be seen as another Prototype.
