Unknown Worlds and Epic Games are currently offering Subnautica for free via the Epic digital store
. This is a limited free offering that will last until December 27th, so we strongly suggest acquiring your free copy immediately (that is of course if you are interested in this game). Subnautica is an underwater, open-world adventure game that tasks players with exploring a vast alien ocean, while trying to survive mysterious creatures who lurk far beneath the surface. Explorers can craft equipment, interact with wildlife and pilot watercraft to explore coral reefs, volcanoes and caves, all while trying to survive.
