2 for 1: The Mystery of the Nautilus/The New Adventures of the Time Machine bundles two previously released titles into one budget-minded package. Immerse yourself in an adventure that takes you 20,000 leagues under the sea as you explore a strange submarine in The Mystery of the Nautilus. Then try and return to your own time period after traveling 800,000 years into the future in The New Adventures of the Time Machine. ~ All Game Guide
