PLAYISM is proud to announce that Million Depth, a deep-diving action strategy game by Cyber Space Biotope, will be released for PC on November 12, 2025.
We will also be releasing a playable demo of the game in September, which features one out of the three routes in the full game in its entirety. Please look forward to further announcements and wishlist the game on Steam to stay updated!
The newest trailer features the game's theme song "Re,Future" for the first time. In the trailer, you'll be introduced to the underground world of Million Depth, Moma across several timelines and her journey to find her only friend, the unique time-freezing, strategic combat system, the crafting screen where you can create any weapon you can imagine, and bartering shops where you can exchange for all sorts of items.
The trailer also features scenes from timelines that don't exist in the actual game, representing the title's theme of parallel worlds. Hints from the trailer can be analyzed alongside the full game experience for an even deeper understanding of the world of Million Depth.
Furthermore, we will be releasing a demo on Steam in September, which features the entirety of Route α, the first route of the game. In Route α, you can get a feel for the basic game systems, as well as the beginning of a story filled with twists and turns, and finally, multiple endings depending on your actions.
Demo save data can be carried over to the full game, so please wishlist the game on Steam and look forward to the demo!
The theme song of Million Depth, "Re,Future", is performed by Ririsya, a singer songwriter VTuber. For her fifth anniversary, she will have a livestream concert on YouTube today!
Ririsya's fifth anniversary concert will be split into two parts, and Re,Future will be performed live during the second half that begins at 9:00 PM (JST). She will also be watching the new trailer on stream and will share her thoughts of playing an in-development demo of the game! Of course, the concert will also feature some of Ririsya's original songs, and viewers can interact with her through the live chat.
The concert will be archived, so even if you can't make it live, you can always watch it later!

A Deep Descent in Search of You
Moma sets off on a journey in search of her friend, who she believes is in the million-floors-deep underground world of Million Depth. However, what awaits is a constantly changing world. The true story behind Million Depth differs between timelines, and Moma's fate too changes with the world around her.
Moma's past decisions have consequences that ripple into the future and even other timelines in unimaginable ways. She will have to piece together fragmented clues from her journey to solve the many mysteries she comes across.
Moma has a "biotope jammer", an incredible device that stops time around her as long as she also stays motionless. It's her key to survival in Million Depth, where all sorts of dangerous creatures lurk in the shadows. Even if she finds herself surrounded by enemies, she can stop them in their tracks to figure out a way to break through.
However, Moma's weapons and shields only have limited durability. During battle, they deteriorate and eventually break. Until they're repaired, Moma becomes completely defenseless, but this is when the biotope jammer comes in clutch. Freeze time, carefully plan your next move, and ensure Moma's survival.
Moma can equip two pieces of equipment, both hand-crafted by combining different types of blocks.
Some blocks can be upgraded by being placed with others of the same type. Use them wisely to craft any weapon, from long-range guns to sturdy shields.
Ultimately, your creativity is what will give you the upper hand.
Throughout Moma's journey, she will encounter several shopkeepers offering crafting blocks, items, and relics that can enhance her abilities.
However, shops in Million Depth don't take traditional payment. Barter with the shopkeepers while keeping a keen eye on the value of your offer and the shopkeepers' mood to get the best deal possible. If it goes well, they might offer you valuable items at bargain prices, but if you get too greedy, you risk upsetting the shopkeeper, who might hike the prices in response.
What's more, the underground world is also home to a strange resource called stockinum, the value of which fluctuates constantly...
