Developer Unknown Worlds revealed the existence of a Subnautica sequel earlier this year, which should comfort fans of tense, eerie survival games. In more distressing news, it seems the developer has been surreptitiously sneaking screenshots of the sequel into the original game, like some malevolent underwater sea creature.
Having evolved that horrible membrane that lets them see better underneath the sea, fans quickly noted some additions to the title's in-game database (thanks, Eurogamer). First thought to be just another aquatic oddity, these additions have since been confirmed by moderators on Reddit to be from the upcoming sequel, Subnautica 2.
