About This Game

Defeating isn’t the only answer.
Imagination creates allies—and weaves the story itself.

Monster Commanders: Nocturne of the Abyss is a groundbreaking turn-based strategy game where you battle using AI and your own words.
You take command as a Monster Tamer, issuing creative prompts to guide your monsters through the battlefield.

◆ AI × Free Text Input × Tactical Battles

Every action in combat is controlled by your own written prompts.
Whether you slash with a sword, cast a buffing ritual, or persuade enemies to join your side—
your imagination shapes the battle.
A powerful language model (LLM) interprets your commands and narrates the combat like a story.

You're not just choosing skills—you’re crafting sentences.
Your words become orders, and those orders bring your monsters to life.
