Ikuu no Tou Hen is an original 3D dungeon-crawler RPG based on Megami Ibunroku Persona. Series staples like demon negotiation and demonic fusion are featured in this, as the game functions similarly to the original title. Dungeons are randomly generated. Dying while in the tower will cause the player to lose all money, items, and equipment they had on them. Players are able to allocate stats to all party members. Experience is allocated equally between party members. There is no voice work, but unlike the original menus, which only used hiragana and katakana, kanji are used.
