Sonic Blast — About this game
Sonic and Knuckles set out to stop Robotnik on a mysterious island. Choose one hero for the journey: Sonic can gain extra height with a second jump, while Knuckles glides and clings to walls for a limited time. Collect rings for protection, break monitors for helpful items and look for the large rings leading to bonus stages. These stages contain the Chaos Emeralds needed to fully defeat Robotnik. Springs and alternate ledges reward a careful look beyond the direct route.
