[Press Release] The Return of Illunes, an offline TRPG with a built-in AI Game Master trained for the game, is out now on Steam

14Dimension Enterprise today released its turn-based roguelike RPG "The Return of Illunes" on Steam (PC) for $19.99. The Nintendo Switch version is in platform review; its release date will be announced later.

The Return of Illunes is the world's first offline TRPG with a built-in AI Game Master trained specifically for this game — it tells the story, judges your actions, and creates subclasses, skills, gear, relics and bosses right on your device.* The language model ships with the game and runs only on the player's PC: no server connection, no subscription, no per-use fees.

Every run, the AI writes the expedition's story and goal, adventure events, battle narration, companion conversations and the ending epilogue. It invents new subclasses, names and gives lore to skills, gear and relics, and stages boss entrances and battle gimmicks. Damage, stats, difficulty and progression are always governed by the game's own rules; player input is filtered before it reaches the model and every generated line is checked before it is shown.

The signature system is Free Action. In combat or events, type something that isn't on the menu — "cut the chandelier rope and drop it on them" — and the AI Game Master judges success or failure and narrates the outcome. The verdict changes the actual result of the fight.

The game supports 13 interface languages; AI-generated text is available in English, Korean and Japanese.

*"World's first" is based on our own research of publicly available information as of October 9, 2026.
