An alien ocean, rich with impossible life.

A lone xenobiologist, adrift in a world of secrets.

An AI, waking from a dreamless sleep, ready to guide humanity to a terrible truth.

In Other Waters is a unique exploration game which balances narrative depth and meaningful relationships with a Metroid-like world of intersecting pathways and alien landscapes.

Explore an alien ocean

Casting the player as an Operator AI, tasked with guiding Ellery Vas as she explores the planet-spanning ocean of Gliese 677Cc, In Other Waters is structured around an ever-growing, tactile interface. Through this unique mode of interaction players will chart underwater courses, scan environments for vital clues, and navigate this unearthly ocean.

Study new life

Rather than play as a sci-fi soldier or planetary colonist, In Other Waters gives players the chance to engage with its world through xenobiology. Players will assist Ellery in tracking, sampling and studying the planet’s life in order to understand how to navigate it’s ocean. Tracking one species might reveal a safe route through predator-patrolled waters, for example, while biological samples of microbes and organic materials can be used to augment the suit for hostile conditions.

Uncover terrible secrets

As they dive deeper into the ocean of Gliese 677Cc, the bond between Ellery and the player will be tested by what they discover. The choices the player makes, and the way they react to Ellery will change the course of the expedition. Through this shifting narrative In Other Waters asks questions about the nature of "natural" and "artificial" life, and investigates what it means to be a human in an epoch of extreme environmental destruction. For life to continue it must change. In Other Waters explores how.
