Welcome to the official Subnautica and Subnautica: Below Zero wiki! Founded in November 2014, this community-maintained encyclopedia covers everything you need to know about the Subnautica games, from the flora and fauna the player will encounter to the vehicles at their disposal.
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.
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.
