About

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 gamepad 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.

作为一个视觉小说,大量文字阅读的游戏,配的字体真是太难读了颜色也很费眼
Played this a while back, and I really enjoyed it! The writing was fantastic and evocative, and it scratched an itch that only Subnautica really has scratched before. The interface was briefly confusing, but then quickly became fun, and I'm impressed by how much was able to be accomplished through UI instead of a more traditional gameplay view. If you like contemplative games, fictional ecologies, or minimalist experiences, I highly recommend.
良いところはたくさんあるゲームだとは思いますが、メインのストーリーは40年前のファミコン時代のような、少々幼稚さの残る環境問題系のSFです。エラリーの人間嫌悪が鼻についてしまいました。どんでん返しがあるかと期待して進めたのですが。
water game fun
Great narrative based game-play. Stripped back of shiny shiny light and sound. I loved it.
no he podido jugarlo mucho por ahora pero lo que veo promete, aunque al principio me está pareciendo soporifero, no por el tipo de juego si no porque no me gusta jugar en inglés, a todo esto un juego que trata de ser una ia y que es solo texto , sin voces, que no esté traducido aunque sea por una ia en pleno año 2026 del señor me parece un horror. Ojalá los devs le dediquen 10 minutos, cojan una traducción hecha por fans aunque sea regulera y pueda disfrutar de este mundo que ofrece mientras tanto voto en negativo
In Other Waters is an incredible game, probably the best I have ever played. Sure it is not a combat game, nor fast paced, but it is the perfect cozy but still unsettling game. It is very introspective and slow, has a great plot, and incredible graphics. I highly reccommend!
I'm having sm fun <3 You can tell the writers really care about the science that inspires this story, and I appreciate that I'm actually learning something while I play. Very chill vibes so far and it's well tailored to my recent gaming tastes (sci-fi, mystery, and underwater games have held my attention lately)
Une expérience déroutante au début mais qui s'avère bien prenante une fois habitué au gameplay. Le point de vue qu'on incarne (celui d'une IA) peut sembler distant de par le coté froidement observateur et analytique, mais cet angle fait fonctionner l'imagination à plein régime. L'ambiance sonore, l'histoire, la manière dont le gameplay se révèle au fur et à mesure contribue à rendre l'exploration passionnante!
If you love science, and want something you can chill out and spend some time with, here you go.
