An alien ocean. One bio-droid. Earth's last hope.

The Subminer is an underwater survival-exploration game set in an alien ocean beneath the icy crust of Enceladus. Mine your way through a breakable environment while being aware of your surroundings — you never know what dangers are watching you from the shadows. Manage your resources carefully while you are underwater. One small miscalculation could mean death. Progress through a procedurally generated ocean spanning three depth levels, each filled with its own secrets, traps and monsters. Death is not the end. Upgrade your toolkit at the end of every run to go a little further each time.

Earth is dying, and you are its last hope. A catastrophic explosion has ripped through the Enceladus research base and silenced it — no signal, no survivors confirmed. The fate of humanity's survival is you: a prototype, a new kind of bio-droid designed for the impossible. Board your submarine and descend into the ocean, mining for resources and fighting deep sea monsters whilst battling your own isolation and fears. Find out what happened — if you can make it out, that is.

Not everything that goes down comes back up. How deep are you willing to go?

Tech Turtles is an independent game studio from Türkiye, born from a shared passion for creating games. The journey began with two developers who met during their university graduation project. After stepping into the mobile game industry, they found their excitement for game development slowly fading. Deciding to take a different path, they left their jobs to pursue what they truly cared about.

It wasn't until they joined forces with two like-minded game artists — who shared the same frustrations and ambitions — that Tech Turtles truly came to life. As a team, they are now focused on creating games that reflect their own vision and creativity. With their first title, The Subminer, they are channeling that renewed passion into something they can genuinely call their own.
