Among countless sci-fi imaginings of the solar system, Enceladus has always been a place particularly suited for hiding secrets.
Its surface is covered by a thick layer of ice, appearing quiet, pale, and even desolate from afar. But once humanity truly understood it, this small moon orbiting Saturn earned a completely different label: beneath its icy shell lies a vast liquid ocean; within the ice particles and water vapor ejected into space lie salts, organic compounds, and chemical ingredients related to life. Thus, "what exactly lies beneath the ice of Enceladus" has gradually become a question shared by both real-world science and sci-fi imagination.
Could there be unseen forms of life? Does the dark seabed harbor a completely different ecosystem? And within those untouched rock layers and sea floors, how many resources remain undiscovered by humanity?
Deep Sea Mining Company chooses to pry open this icy shell directly, sending players into that sunless ocean—but this time, you're not here for scientific research.
You're here to mine.
Take the submarine underwater; how much you mine depends on how deep you dare to go
Deep Sea Mining Company is a deep-sea mining Roguelite game set in the subsurface ocean of Enceladus.
As Earth's resources gradually deplete, Enceladus becomes a new site for resource extraction. A sudden explosion destroys the local research base, forcing mining operations to halt. As a prototype android built for extreme missions, the player must board the submarine again, venture beneath the ice shell, and continue the unfinished mining tasks.
Each departure starts with a seemingly simple goal:
Dive, explore, mine, and try to bring Everythinggj back alive.
The underwater environment changes with each exploration; ore veins, routes, and encounters won't always appear in familiar ways. As you dive deeper, the resources you discover become more tempting, but the risks increase accordingly.
So the question quickly shifts from "Where are the remaining ores?" to "Should I really keep going deeper right now?"
With a ship full of resources, do you return now to secure your gains, or dive one layer deeper? Can the submarine hold up? Is the path ahead worth the risk?
After all, in a Roguelite, greed isn't necessarily a bad thing—provided you can actually make it back.
No pre-existing mine tunnels on the seabed? Drill your own.
Exploration here isn't just about moving along fixed corridors.
The underwater environment in Deep Sea Mining Company is destructible. Rock layers blocking your path can be drilled directly, and some areas allow you to create new entrances by destroying terrain and triggering chain reactions.
Faced with complex underwater structures, you can either carefully search for a passage, or check your available equipment and decide:
Why not just dig straight through here?
The submarine runs through the entire diving process. It serves as a tool for transporting minerals, essential equipment for venturing into unknown areas, and the player's lifeline in this alien ocean. With each successful return, resources brought back can be invested in base and equipment upgrades, giving the submarine stronger exploration capabilities and allowing future missions to reach places previously inaccessible.
However, there's clearly more than just ore beneath the seas of Enceladus.
NPCs scattered across different areas, side quests, special passages, and hidden shops can all steer an ordinary mining mission in a completely different direction. And those things lurking in the darkness will constantly remind players: this has never been an underground mine waiting to be quietly excavated.
Why did the research base suddenly explode?
What exactly happened on this seabed before communications were cut off?
Keep going down, and you might find the answers sooner or later.
Public Playtest is now open—come take a mining trip to Enceladus
From piloting the submarine to drill through the first rock layer, to constantly weighing risks after discovering ore veins, and returning to base with a shipload of resources to upgrade equipment, Deep Sea Mining Company combines mining, Roguelite exploration, resource management, and evacuation decisions into a dark, alien deep sea.
You always know why you're going down this time—for resources.
But it's hard to know what you'll dig up in the next layer.
Deep Sea Mining Company is currently available for Playtesting on Steam and supports Simplified Chinese. Players can now apply to participate in the test via the store page and be among the first to dive beneath the ice of Enceladus.
If you enjoy mining, Roguelites, deep-sea exploration, or are simply curious about "what's hidden beneath the ice of Enceladus," feel free to join this Playtest and add Deep Sea Mining Company to your Steam wishlist.
The submarine is ready.
