Voyage is a point-and-click adventure inspired by Jules Verne's two novels From the Earth to the Moon and Around the Moon. But unlike those two books, the main character actually makes it to the moon surface, although his two companions do not survive the trip.
As the game begins, Michel Ardan explores the space capsule in which he and his co-travellers arrived. The time period is the early 20th century and the interior of the capsule is depicted with plush velvet cushions, brass details and gadgets derived from the science of the time. Eventually, after discovering the cause of his companions' deaths, Michel can leave the capsule and explore the moon. Strange landscapes and unusual creatures and beings await him.
Eventually Michel will discover Selenite City, home of the Selenites, an ancient and highly intelligent lunar race. With each step of the journey, questions arise as to the fate of the Selenite people: Did they deteriorate, like so many of the statues they left behind? Did they leave the surface to seek refuge in the center of the moon? Once players answer these questions, they may find their way back to earth with news of their fantastic discoveries.
Intermixed into the story line are various types of puzzles that involve logic and deduction. Communications and finding important inventory objects to use are included the puzzle mix. You'll also find several puzzles based upon sound and music. Learning an alien language also comes into play. As you discover new things and solve the various challenges, you'll receive points that increase Michel's IQ. As that IQ rises, more complicated solutions become available, supposedly adding to the replay value of the game.
