ISEEKAI RPG: DUNGEON is a free 18+ text RPG run by an AI game master.
You name a universe: an anime, a game, a book, or one you made up. The game builds a dungeon inside it, with that universe’s characters as enemies, elites and recruits. There is a 10-floor training dungeon and a 100-floor main one, a base you grow from a single cottage into a town, and a roster of characters you bring back and can visit, date and equip.
What separates it from a chatbot is that the numbers are real. Combat, economy, exhaustion and relationship stats are computed by the game, and the narrator describes the result. The game keeps a lorebook, so what happened ten hours ago is still true.
Adult content comes from two places: scenes after you defeat or subdue an enemy in the dungeon, and a relationship layer with the characters living at your base. Text and images are generated live for the scene you are in. All characters are adults.
Before you download:
– It runs online. The download is a small client that opens the game in its own window, and it needs a connection the whole time.
– The game master and the images are AI.
– Windows (one file, no installation) and Android (APK). There is no Mac, Linux or iOS build.
– Free, no account, no turn limit. Nothing is sold.
– It is a test build and it breaks sometimes. The devlog on the page says what was fixed in which version.
