Legend has it that a brave knight named Drak sealed an evil god named Deoric beneath the six continents of Mistral. However, peace never lasts, as the Garuda Empire has invaded the lands of Mistral, with its Dark Generals, led by Sornbul, conquering the continents.
Duran, descendant of Drak, is the only one who can stop the Garuda Empire's plan to resurrect Deoric and plunge the land into chaos. With the power of Drak's mystic armors, he heads off to stop Sornbul at any cost.
The six continents of Mistral can be challenged in any order, each filled with hordes of demons and one of Sornbul's Dark Generals. Before a level, the player can choose from four elemental armors, each with its own bullet spread and unique bomb. The armor's attack can be powered up by finding jewels dropped by enemies.
The player must also manage the armor's health, which is reduced when hit. Enemies drop crystals that are used in between-level shops to buy additional health, bombs, and continues.
