Happinet announced on October 31st, 2022 that Haunted Dungeons: Hyakki Castle would be leaving Steam on November 13th. It is likely that the game was also delisted on Japan’s DMM Games service around the same time. No reason was given for the delisting and Happinet continues to operate as a developer and publisher on Steam as of February 2023.

We would like to announce that “Haunted Dungeons: Hyakki Castle”, which was released on November 14, 2017, will be discontinued on November 13, 2022 due to various reasons. We will continue to develop new games for your enjoyment.

About the Game

The 2 Party System has been improved for better combat!
When you divide your party into 2, the group you aren’t controlling turns to stone and has greatly increased defense. Some Yokai cannot be attacked from the front so use your stone companions as shields and strike your foes from behind.Enjoy thrilling battles never before seen in Hyakki Castle!

Each floor has been revamped and improved with new mechanisms!
Every floor has been reimagined with new and improved traps, mechanisms, and Yokai placement. New mechanisms and floor layouts have been replaced to improve the play experience!

Yokai with new powers and behaviors!
From teleporting Gaikotsu Yujo, to Gyuki suddenly striking from the ceiling, certain Yokai have gained powerful new abilities!

Battles with Boss Yokai have been revamped!
Most boss Yokai battles are completely different this time around. One change for example: the 2nd boss, Haragao no Mure, advances through 3 rooms. In the final room, a Shokandama and multiple fakes will appear. Make sure to attack the real one!

Choose from 3 control settings!
