a xenobiologist who discovers extraterrestrial life while searching for her missing partner.

When Ellery is called to planet Gliese 677Cc by Minae Nomura, only to arrive at an abandoned base, she finds herself adrift in an ocean of secrets, with little more than a malfunctioning diving suit and a strange AI to guide her. You are this AI.

Guide Ellery—and keep her safe—as you dive deeper and explore an underwater alien landscape. The planet’s unique life, and its dark history, are yours to uncover and the bond between you and Ellery will be tested by the secrets you learn. 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.

Freely dive into an expansive section of seafloor, from shimmering reefs to inky depths. Unlock upgrades and make discoveries that allow you to open up new paths, uncovering strange creatures and environments as you do.


Navigate an elegant, intuitive UI via touch or mouse controls. Interpret signals, set headings, and map the ocean through experimentation and intuition.


Discover and catalogue species through observation, scanning, taking samples, and interacting with alien life. Read Ellery’s notes, look at her sketches, and help her classify an entirely new ecosystem.


Choose whether to study creatures, investigate secrets or dive new areas, then come back to your base to study samples in the lab, chat to Ellery or read her journals to understand more about this world.


Through limited communication learn more about the person whose suit you inhabit, and help guide her towards a terrible truth. What you experience together will bring you closer.
