Ashley is a psychic, or medium, living in a post-apocalyptic world. She has had recent nightmares about a burning house, and is then contacted by the Fraternity of Mediums about the same house seen in her dreams. Following the Fraternity's invitation, she decides to investigate the house and its background and look into why it is the topic of her nightmares.
Age of Enigma: The Secret of the Sixth Ghost is a hybrid hidden-object and traditional point-and-click adventure game. It is more involved than your typical "casual" adventure, combining inventory based puzzles with logic puzzles, memory games and standard adventuring.
The game is played from a first-person viewpoint, with cartoon styled graphics. It has a variety of different art styles for the different areas of the game, ranging from the overall story which is set in a bleak, oppressive post-apocalyptic world, to a Japanese Zen garden, beaches and pirate ships, and more.
