Introduction:

HARMA: Eden of a Fallen Kingdom is a dark fantasy roguelike deck-building game featuring a story mode.

◆ A Harsh Fate’s Tale
Upon returning from their expedition, the knights of the Harma Kingdom began slaughtering civilians one by one. Yet King Taron Harma—leader of the expedition—is nowhere to be found. Prince Eden Harma stood against the corrupted knights and protected his people, only to face betrayal and disgrace in return. Amid this tragedy and despair, he must uncover the truth behind the corrupt knights and his missing father—and stand against evil.

◆ Unique and strategic gameplay through Artifact Tuning System
In HARMA, card power is randomly determined by whether three artifacts are successfully tuned. If all three tuning attempts succeed, cards unleash maximum potential.

Additionally, players can spend focus to guarantee successful artifact tuning before playing a card. Will you rely on luck or use focus to secure victory? This choice could turn the tide of battle.

With two playable characters and over 300 diverse cards and artifacts, craft your own unique deck and strategy.

◆ Story Mode
The story mode offers an epic four-act narrative. Through conversations with numerous key figures and cinematic cutscenes, players will deeply experience a world on the brink of collapse and its tragic fate.

◆ Rifts of Dimension
For those who want to focus purely on combat and strategy without story elements, challenge the Rifts of Dimension mode. This replayable mode features only battle—test your skills again and again, facing fresh challenges each time and pushing your limits.
