While visiting Flicky Island, Sonic 3D Blast notices that the Flickies, his small, feathered friends that can travel between parallel worlds, were captured and turned into badniks (the robot enemies of Sonic) by Dr. Robotnik in his never-ending quest for the Chaos Emeralds. Seven levels separate Sonic 3D Blast from the final showdown with Robotnik.
Sonic 3D Blast was the last Sonic 3D Blast title released for the Sega Saturn, the only platforming presence of the blue blur in the Sega Saturn, and one of his rare appearances in Personal Computers. The title, considering the era it was released, is somewhat misleading, as instead of full blown 3D graphics it uses an isometric view where Sonic 3D Blast can move not only forwards and backwards, but also left and right.
Sonic 3D Blast gameplay is much slower when compared to other games in the series, and the number of badniks is reduced to five in each section. As usual, when Sonic 3D Blast destroys one badnik, an animal leaps free from its insides, but this time Sonic 3D Blast has to pick him up and lead them to an interdimensional ring. While they can be taken one by one, exploring the level with all five allow the player to reach for otherwise inaccessible continue tokens.
Sonic 3D Blast is released on November 30, 1996 for the Sega Saturn.
