Sonic the Hedgehog (Master System) EU Manual

From Sonic Retro

Story

Dr. Ivo Robotnik, the mad scientist, is snatching innocent animals and turning them into evil robots! Only one tough dude can put an end to the demented scientist's fiendish scheme. It's Sonic, the real cool hedgehog with the spiked haircut and power sneakers that give him super speed.

Help Sonic fight hordes of metal maniacs with the Super Sonic Spin Attack. Speed down rolling hills and leap over dangerous booby traps. Then splash through the chilling waters in an underground cavern. And if you're lucky, you can warp to the Special Stage where you jump from springs and bounce off bumpers as if you're in a real pinball machine! Your greatest challenge lurks in a flying blimp where you come face to face with Dr. Robotnik himself!

Spin 'til you're dizzy, save the animals and become the super hero. Be Sonic! Be Atomic!
