About
Earth, 1976. The cold war is in full swing and you have been tasked to construct and direct a deep sea research facility working to perfect human cloning. Survive against the odds in the extremely unforgiving abyss maintaining oxygen, power, food, and much more to keep your crew alive. Discover and mine resources for construction, light your way in the dark, and expand into your surroundings to advance your research. Capture the diverse, highly-adapted flora and fauna of the deep, but beware: the darkness hides unexpected horrors, with only the light keeping them at bay.



Lead a team of scientists conducting genetic experiments on local wildlife on the ocean floor.
Keep your population sane, obedient and alive as you expand your base and discover the secrets of cloning and genetic research.
Improve life and progress in your facility by researching advanced technologies.
The fate of your crew is in your hands! Make crucial decisions through the event system.



Ensure the survival of your crew by planning, placing and building essential infrastructure for manufacturing, research and life support.
Expand and optimize your base and its available resources. Connect your buildings and mining facilities efficiently with tunnels and powerlines.
Conquer the uneven terrain of the ocean floor with clever planning and vertical construction.



Build light pylons and push back the darkness to expand your base.
Secure resources far away from your main base by using exploration submarines and outposts.
Prevent disaster by making sure power does not fail, together with life support and light sources.



Your crew senses it, and so do you. Something is lurking at the edge of darkness, slithering and seething.
Darkness is danger, light is safety. Do not turn off the light.

I like city builders, and I like the premise for this game, but I just found the flow of gameplay so boring. I wish I could like it.
yes, its surviving mars but under water, I haven't played much of this one but I would recommend both. with more time I would say surviving mars is better however I'm still not done, but even if it improves (its still good mind) surviving mars has a lot more to offer. i said all of that before finishing the game, very disappointing overall, play something else

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.

besides the constant crash to desktop and extreme game slow down late game, i like it and got to near the end, but with the slow down and stutter and constant crashes cannot finish. otherwise 4 stars. it is quite difficult to balance everything and with limited population gets extremely difficult. got to manage everything in micro-doses
Гра непогана і дуже атмосферна. Можливо, я не застав її на виході, тому всього не бачив, але як мінімум критика через нестачу життєво необхідних ресурсів мені не дуже зрозуміла, адже принаймні безкінечне вугілля тут цілком є. Основна складність це балансування "приплоду" населення з його життєвим циклом, цього майже нереально повністю досягти. Але на те й ігрова механіка, щоб створювати челендж. От справді мінус у тому, що гра жадібна до ресурсів і починає досить відчутно тормозити, коли маєш велику базу та кілька аванпостів. Також дещо кострубатий різнобарвний інтерфейс, у якому спочатку складно розібратися. Проте загалом я отримав свою порцію задоволення і можу її порекомендувати тим, хто цікавиться підводними базами, адже таких сетінгів зараз виходить малувато.
the game is fun and intresting
Takes a bit of trial and error to get the hang of, and some things could be better balanced than they are, but on the whole an enjoyable and challenging base builder that's worth a look by fans of the genre.
A bit buggy (ran into the unhoused employee bug) and had performance issues mid-late game which required restarts to fix, plus I think some of the game play mechanics are a bit shaky (just using outposts instead of lamps was a bit of a game breaker, and mining subs rapidly lost their usefulness) but overall I quite enjoyed this. Pity it looks like its wrapped up - very pretty, good premise, setting had plenty of opportunities to expand. Worth a play.
Too laggy
Amazing game, nice gameplay offering both challenge and peace at times with a great story and unexpected ending. just wish this game had a sequel
cool, unique survival city builder. story has its pros and cons, and not everything is well explained ingame, but the athmosphere and uniqe mechanics really make it up
