HoloDungeon: Koyori vs Hollow Live in Honsha Tower v1.3.0 update adds full English localization on June 25

Velux Studio and holo Indie have announced that they will soon release a major update for HoloDungeon: Koyori vs Hollow Live in Honsha Tower that adds a full-fledged English localization for the Japanese roguelike game. This update, set to release on June 25, will raise the game's version to 1.3.0.

The same update will also notably add new Hollows based on Kobo Kanaeru, Koseki Bijou, Fuwawa & Mococo Abyssgard, Momosuzu Nene, and Shishiro Botan. In addition, it will have a major overhaul to ranged combat that might also see the retirement of arrow items in existing players' inventories.

You can find a copy of the patch notes after the jump right below. HoloDungeon: Koyori vs Hollow Live in Honsha Tower has been available first in Japanese via Steam Early Access since last January. Velux Studio is currently planning to launch the game's full release around the first half of 2027.

To everyone who has been eagerly waiting: We are thrilled to announce that HoloDungeon, the traditional holo Indie roguelike, will officially feature English in-game localization starting with tomorrow's update on June 25!

This English localization arrives alongside our 3rd Major Update during the ongoing Early Access period.

In Version 1.3.0, the Chemical Launcher system overhauls ranged combat, expanding the mechanics to drastically elevate both the strategic depth and the sheer fun of tackling the dungeon.
Simultaneously, we are introducing a new practice dungeon designed specifically for beginners, numerous support features, and high-difficulty dungeons that will push seasoned players to their limits—greatly expanding the game's overall depth.

Due to the nature of the roguelike genre, HoloDungeon might not always be an easy game. However, our ultimate goal is to create an experience that brings joy to both hololive fans and roguelike enthusiasts alike. We truly hope you will continue to support the game as it evolves throughout the rest of our Early Access journey!
