Sonic Blast is a side-scrolling platform game. In order to stop Dr. Robotnik from using several Chaos Emerald shards to fortify his base, the player must control Sonic and Knuckles the Echidna through 15 levels. As a Sonic the Hedgehog series platformer, the characters run and jump to reach the end of a level while defeating enemy robots and collecting rings. In separate bonus stages, the player must run forward and collect rings to earn one of the Chaos Emerald shards. (wikipedia.org)
