You choose a favorite and walk beside them. But those you left behind — where do they go while you're gone? LUNADUN: LUNATIC DUNGEON is an emotional adventure where choices shape the fate of four characters. 'The ones you loved, the ones you ignored — you don't get to walk away from either of them.'
LUNADUN: LUNATIC DUNGEON
SteamDo you have a favorite character?
Picking the one that speaks to you, going on adventures together, having conversations — that's one of the best parts of any game.
But have you ever wondered: what happens to the characters who never got to be your favorite? How do they feel during all that time you weren't there? When you next open the game, do you really think they'll greet you with a smile — just like your favorite always does?
LUNADUN: LUNATIC DUNGEON is an adventure game built around that very question. Your choices determine the fate of every character.

Galuo "Your Childhood Friend" / "The Childhood Friend Someone Wanted"
A hotheaded young man who charges headlong into a dangerous dungeon, driven by a single-minded desire to save a mutual friend. Beneath the surface, however, he is slowly consumed by the compulsion that he must never stop living up to everyone's expectations.

Albie "An Ordinary Scout" / "A Scout Who Could Never Be Special"
A earnest young man who joins the party despite his doubts about the mission. Neglected by his father in childhood, he came to believe he has no worth of his own — and has held himself together ever since by making himself replaceable.

Megalis "A Wandering Monster" / "A Monster Who Survived Anyway"
A mysterious monster woman who leads a caravan. She has endured the harshest of conditions — stripped of dignity, armed with nothing but her wits. Even the tragedies she has suffered, she claims, are no one's fault but her own.

Mamakona "The Daughter of Fate"
A childhood friend waiting for you at the end of a long journey, at the very edge of the story. What meaning will her presence bring to all the choices and responsibilities you've accumulated along the way…?

You
You, in this game. A fleeting form, stripped of everything.

――Their fates are mirror images of each other. One person's salvation is another person's ruin.
"The ones you showed kindness to, the ones you turned away — you don't get to walk away from any of them."
