The early access version of Subnautica 2 provides roughly 20 hours of gameplay on a watery alien planet. However, the current build ends abruptly and features limitations that may reduce enjoyment.
Unknown Worlds has made Subnautica 2 available in early access following the successful model of the original game from 2015. Players begin by crash landing with an AI companion named NoA and must investigate black box signals through a series of tasks that lead to upgrades and exploration. The build includes opportunities to build bases, craft tools, and dive to greater depths before reaching its current limit.
