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.

100% recommended! I was so invested in the story all the way through. Immersion is perfect. I've finished the story in about 6 hours, but the exploration and quests are currently at 60%. I'll definitely keep playing to finish and to find out all I can. I'm captivated. Need. to. know. everything.
I love this game! The mystery / explorer objective part is intriguing with a unique game play and graphics. I like how despite it being a fairly low-sensory video game, I am drawn in and invested! I am enjoying the lore built into this whole ecosystem and universe.

For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

A beautiful and fun game with unique gameplay mechanics
What a gorgeous little game, never played something quite like it.
Short and sweet game. Worth it on sale - about 7 hours of gameplay (kept getting lost) but I'd be interested enough to replay eventually. Simple interface, focused on exploration. Atmospheric. The mystery kept me interested throughout, and I admit I shed a tear [spoiler]at the bottom of the deep vents when the singing started.[/spoiler]
Very simple game with a nice story! I think it could have played out a little faster and maybe changed the controls a bit to make it feel better. At times it felt annoying to change modes from exploring to moving; it feels like it could have been one mode. Alterations to the sampling module would have also been very nice. I think overall the game was neat but didn't need to take 6 hours. Maybe 3. Unless more things were added so it didn't just feel the same. Really cool concept that created a pretty memorable experience! Nice vibey soundtrack and cool way of using such a limited HUD to create such a picture in my mind!
In Other Waters - 孤星寂海 是款单人‑叙事驱动・外星海洋探索冒险 / 解谜独立游戏 +UI风格 +环境音乐 -游戏的过程主要是在类似于地形剖面图的2D平面视角上进行的 个人认为要是在每个地点加上对应的美术插画会让游戏更加的耐玩 单调的地形剖面图不断消磨着我的审美,有时候真让我感觉是个瞎子一样,虽然有着文本描绘着眼前的场景,生物漂浮过的声音刺激我的感官,但是缺少了对应的美术插画让我在游玩过程中逐渐审美疲劳 -剧情的发展 前期的剧情发展十分不错 但后期赶图太繁琐了,单调的地形剖面图加上固定不断需要移动的点位在慢慢吞噬耐心 总体来说是款十分不错的游戏,UI处理的很好
A beautiful short game about exploration on a new planet. The gameplay is simple but the story is complex and I actually liked the balance of that this time. This game takes patience and curiosity and there are no achievements so if you play this, you play it to love it and I loved it. C:
Really novel and cool gameplay/presentation. The marine ecosystem they designed is really interesting and I read every bit of lore I could find, something I don't usually do.
great game with thoughtful writing and fun worldbuilding despite being mostly text-based, a fun adventure when on sale but deff get the accompanying art book to fully delve into the world
