It seems simple enough. You have discovered an S.O.S. message from a spacecraft in danger of exploding on a far-flung planet and need to find and rescue them. That's when the fun begins; as you travel through the book using lateral thinking, imagination, perseverance, code breaking and anything else you can squeeze out of your brain-box to plot your way through the maze. Following the simple and witty instructions you are left to find your way up and down stairs, along corridors, through tunnels, up elevators and any other possible route through the page. Each spread brings a new and different challenge as your journey moves from city to space station, from mining colony to jungle, until you reach an the stricken craft and begin the exciting and intriguing conclusion which tests your previous puzzle-solving skills. And once you've succeeded, if your brain isn't completely frazzled, you can play again - trying to find a quicker route to the imperilled spacecraft.
