Next book >>

Metal City Mayhem is the first Sonic the Hedgehog Adventure Gamebook published by Puffin Books under the Fantail imprint. It was released in 1993 and written by James Wallis.

Sonic gets distracted by a tough Game Gear game, and while he is not looking, all of his friends are kidnapped. This really frustrates him because he needs to consult with one of his friends on how to beat the game's final boss.


Have you got what it takes?

Mobius is under threat from the deranged Robotnik. The demented inventor is busy on a master plan building mega-robots. Only you and Sonic can stop him.

Using your skill, speed and agility, you can help Sonic save the day. But think fast and move quickly, Sonic doesn't hang about and there's no time to waste. The future of Mobius depends on you!


  • In the list of Other Sonic Adventure Gamebook titles that appeared in the back of later books, such as Sonic v. Zonik, the title of this book is given as Robotropolis. The name may have been changed to avoid confusion with Robotropolis, the capital city of Robotnik's empire in the Sonic the Hedgehog Saturday morning cartoon.
