Rygar: The Legendary Adventure takes place on an island in the Mediterranean Sea called Argus. Rygar is about to receive a wreath from Princess Harmonia in a ceremony for a victorious naval battle, when Titans suddenly attack led by Echidna. After she and Icarus capture Harmonia, Echidna has the Minotaur dispose of Rygar with a pit torn open in the ground. Surviving the encounter, Rygar finds the Diskarmor, a legendary shield of the gods and is given task to stop the Titans in order to rescue Harmonia and bring peace to Argus.
In Rygar: The Legendary Adventure, the player traverses the landscape armed with the Diskarmor, defeating enemies, collecting power-ups, and so forth. The camera is fixed in one location, but rotates when the player moves around accordingly. The game has many unlockable features, like picture and movie galleries.
