Description

Fusty Dungeon sends you into ancient ruins in search of a cure for a curse afflicting your childhood friend, a female priest. As a knight serving in the Imperial Church’s ruins research unit, you must venture into the dungeon alongside her and uncover the clues that could lead to treatment. Your mission brings together a personal quest to help a longtime companion and your duties as a member of the Church’s research team. The two of you won’t face the entire journey alone: a rather peculiar witch joins your party along the way. With the answers hidden somewhere in the ruins, conquering the dungeon is at the heart of your search for a way to lift the priest’s curse. Developed by Vitamin rice and published by Shivarune and Co-Fun Games, Fusty Dungeon was released on September 24, 2026. Its original Japanese title is ラスティーダンジョン, and it is also known as Rasutii Danjon and Lusty Dungeon. Version 1.0s is available for Windows in English through DLSite and Steam, with mosaic censorship.
