The Tower of Druaga (Druaga no Tou) is a legendary action-RPG released by Namco in 1984. Set in a world inspired by Mesopotamian mythology, players control the hero Gil on his quest to climb 60 floors of a labyrinthine tower to rescue Princess Ki from the demon Druaga. The game is famous for its hidden treasures—each floor contains a secret chest that only appears after performing a specific, often cryptic, action. As one of the earliest examples of the action-RPG genre, it deeply influenced the development of 'The Legend of Zelda' and 'Dragon Slayer'. It is a classic of puzzle-solving and combat that rewards experimentation and patience.
