Sonic Blast is a video game in the Sonic the Hedgehog series developed by Aspect and published by Sega for the Sega Game Gear. It is known as G Sonic in Japan. It was released in November 1996 for both North American and European markets. A Japanese release followed later that year on December 13, being the last commercial title released for the system.
The game was also ported to the Sega Master System in Brazil by TecToy and released in December 1997.
Sonic Blast was later compiled with other Sonic titles in Sonic Adventure DX and Sonic Mega Collection Plus, and a demo of its ending can be unlocked in Sonic Gems Collection.
While this game was released in conjunction with the similarly named Sonic 3D Blast, the games have little in common. No enemies, levels, or bosses are shared between them. The story is also completely different; Sonic and Knuckles join together to collect five of the Chaos Emeralds and confront Eggman at Silver Castle.
