In Other Waters is a non-violent sci-fi video game in which players take on the role of an Artificial Intelligence (AI) guiding a stranded xenobiologist through a beautiful and mysterious alien ocean. Players explore the expansive section of seafloor, from shimmering reefs to inky depths, unlocking upgrades and discovering strange creatures along the way. The AI navigates an elegant user interface via touch or mouse controls and interprets signals to set headings. Players can discover and catalogue species by observation, scanning, taking samples, and interacting with alien life while monitoring Ellery's notes to help classify an entirely new ecosystem. There are options for studying creatures, investigating secrets or diving new areas as well as returning to base afterwards to study samples in the lab or read her journals.
