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.

Macht Spaß, ist aber auch sehr fordernd. Story könnte länger sein.

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.

I like it, but I wish it had more updates. Once again, a game with a premis unique enough that it keeps me engaged far past what the gameplay or mechanics normally would. Difficult early game that is largely trivialized by the time you reach the end. I say largely, because you CAN still become royally screwed if you expand without taking account of all your needed resourses. I think it deserves better reviews than it has, given the fact that there is no other game like it rn. That said it's not for everyone, but there is fun and enjoyment to be had here
very challenging
很好 很有意思
Paradox abandon too many early access games... my trust is severely frayed...
I really love city builder survival games. This one though, is a bit meh... It's fun, but it has many QoL issues and it seems abandoned, get it at a discount and it's nice, probably a 6,5/10 in my opinion. Still worth it if you like these types of games, considering how few exist.
intersting game, but after 5 hours you think that there is something missing in the tech tree, seems like devs had allot more in planing, but didnt make it. but all in all its a 20€ game
It's not that bad as it may seem from the reviews. It is unpolished and the ending feels rushed, the game can be finished in about 8 hours but with the 50% discount I think it's worth the price. I haven't seen any game-breaking bugs but there were some minor ones, mostly tunnel pathing related. All things considered, get it on sale.
