Players explore an Egyptian town and ruins from a first-person perspective. The game combines role-playing game elements with an adventure game-like interface. Players may purchase items from shops, though some shopkeepers must be defeated in battle before trading. Battles are turn-based, with options to fight, use items, or flee. Players accumulate experience points by succeeding in battle and "level up" after gaining enough experience, which increases their stamina. Randomly encountered battles with enemies may happen at any time, including when paused to examine the inventory.

The player character, Daisuke Kusano, is the son of an archaeologist who disappeared while searching for the Tears of Isis, artifacts once owned by Cleopatra. During the man's excavation for the Tears, demons appeared and abducted him. The boy soon learns that he must find the Tears in order to save his father. Over the course of the adventure, Daisuke visits the Great Sphinx of Giza, the Temple of Kom Ombo, a tower of sand, and an underground labyrinth. At the end of the game, he discovers that the demons had been disguised as the kindly shopkeeper. Daisuke receives the last Tear of Isis upon defeating the demons, which summons the ghost of Cleopatra, who releases Daisuke's father from imprisonment.
