The Subnautica games are a series of open-world underwater survival games developed and published by Unknown Worlds Entertainment.
Set on the fictional Planet 4546B, the original Subnautica follows the story of Ryley Robinson, the only survivor of the crash of the Aurora, as he tries to survive on the alien planet, investigate the crash, and return home.
Subnautica: Below Zero takes place two years after the first game. Robin Ayou travels to 4546B to learn the true fate of her sister and crash-lands in the icy Sector Zero.
Both Subnautica and Below Zero are available on Windows and Mac (through Steam or Epic Games, or Microsoft for Windows only), PlayStation 4 and 5, Xbox One and Series S/X, and Nintendo Switch.
