Unknown Worlds ocean and tactics

If you like alien oceans, squad tactics or quiet puzzles, these six games from Unknown Worlds Entertainment give you survival crafting, team shooters and calm Sudoku to explore.

You can start with Subnautica and Subnautica: Below Zero, where you explore sunlit reefs and icy waters, collect food and resources, and put together shelters and small vehicles to reach deeper areas. That focus on learning a place and preparing the right gear runs through the rest from Unknown Worlds Entertainment too, whether you are coordinating teams in Natural Selection 2, placing figures in Moonbreaker, building together in Subnautica 2, or solving number grids at your own pace in Zen of Sudoku.
