Coming Soon To Early Access

The developers of this game intend to release as a work in progress, developing with the feedback of players.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We plan to implement a vast amount of content and features to enhance the gameplay experience. Because of this, it will take a significant amount of time to complete all the planned elements.

Our goal with Early Access is to release the game as soon as possible and incorporate player feedback into our long-term development process. This will allow us to improve the quality of the final version and deliver the gaming experience that players truly want.”

Approximately how long will this game be in Early Access?

“The specific release date has not yet been determined. We expect the Early Access period to last for 1 to 2 years, and we are currently aiming to release the full version in the first half of 2027.”

How is the full version planned to differ from the Early Access version?

“The Early Access version includes the scenario up to the midpoint of the story, while the full version will cover the complete narrative.

Regarding gameplay content, we plan to implement at least two main story dungeons, one of which is currently available. However, features such as buying and selling items within dungeons, identifying unknown items, and the map system are planned but not yet implemented.

Similarly, we are planning to add high-difficulty content that utilizes these mechanics, additional playable characters, and more enemies. We also plan to add multi-language support in the future.”

What is the current state of the Early Access version?

“Currently, the game features one Main Scenario Dungeon and four Optional Side Dungeons (including the tutorial). It also includes a challenging multi-phase boss battle.

There are three Hub Maps, and the events occurring in each location are already implemented.

However, please note that some dungeon mechanics and Quality of Life features intended to enhance gameplay convenience are not yet implemented.”

Will the game be priced differently during and after Early Access?

“The price is likely to increase upon the full release. We may also raise the price at specific points during the Early Access period.”

How are you planning on involving the Community in your development process?

“The core gameplay of this title focuses on dungeon exploration. The game features a wide variety of dungeons, including high-difficulty challenges and special dungeons that emphasize unique gameplay mechanics.

In addition to progression-focused content, some characters and items in the game are inspired by Hololive VTuber talents.

During development, the team will closely monitor player progress and community reactions to determine what kinds of content expansions players are looking for. Feedback will be primarily gathered through channels such as our official X account (@holo_dungeon).

Throughout the Early Access period, this feedback will be used not only to adjust the difficulty of gameplay elements, but also to plan new expansion features, improve usability through new systems or revisions to existing ones, and determine additional characters to be implemented.

In addition to direct feedback sent to the development team, we will also review gameplay streams, recorded play videos, and community comments associated with them, and use these observations to help guide future development decisions.”

About This Game

With the special live performance just around the corner, Hakui Koyori was living a hectic life, her heart filled with both uncontrollable excitement and anxiety.
Just as most of the meticulous planning was complete, the world suddenly transformed into the mysterious labyrinth known as the “HoloDungeon”.

“Oh noooooo! Help me, Koyoriii!”
“La, Lap-chan!?”

And soon after the incident began, a fellow member of the same secret society was too quick kidnapped. Can Koyori save her friends and successfully hold the special live performance...

■HoloDungeon

The HoloDungeon is a dungeon that shifts its form like a hologram.
Layers are automatically generated, ensuring no adventure is ever repeated twice. A fresh and exciting experience awaits you every time.

If you fall in the dungeon, you will lose many things gained during that adventure, such as picked-up items and experience points.
However, the knowledge gained from that adventure will surely help you on your next one.

Also, “Dungeon Experience Points” are not lost even if you fall in a dungeon, and the “Decorate Recipes” obtained by paying these points are also important keys to clearing the dungeon.

■Hollow

An existence not dissimilar to Hololive talents, yet replicated by someone being. The Hollows, each possessing diverse ability and characteristics, await the protagonist, Koyori.
However, if you can fully understand Hollow's unique character, you might be able to use that to your advantage in your strategy.

■Items and dungeon traps

Items and traps found while exploring HoloDungeon are packed with Hololive elements!

Even items or traps that seem tricky at first look may become your savior in a pinch, if utilized properly.
Of course, the reverse is also true.

■Decorate System

By using “Koyorinium” accumulated during dungeon exploration, you can blended new medicine or perform “Decorate” to dramatically enhance the performance of weapons and armor.

These effects are extremely powerful and can serve as a trump card to decisively break through seemingly deadlocked situations.

Items with weak or disadvantageous effects can also serve as important “Decorate” materials, bringing a fresh sense of strategy to dungeon exploration.
