Story: Robotnik has a new Death Egg in outer space, and Sonic and Tails learn of its creation. Tails has a rocket called the Lunar Fox that can send only one person into outer space, and the rocket needs eight Chaos Emeralds to power it. A tournament will decide who will take the emeralds into outer space to face Robotnik.
Levels: The levels and opponents
are as follows:
South Island - Knuckles
Flying Carpet - Amy
Aurora Icefield - Bark
Mushroom Hill - Espio
Canyon Cruise - Tails
Casino Night - Fang
Dynamite Plant - Bean
Giant Wing - Sonic
Death Egg's Eye - Metal Sonic
Death Egg's Hangar - Robotnik
Chaos Emeralds: There are eight Chaos Emeralds in the game, which are obtained by defeating opponents in the first eight matches. Sonic can transform into Super Sonic, but he must not lose a single round up until the second match against Metal Sonic (at which time he can transform).
Miscellaneous: Two new playable characters are introduced in Sonic the Fighters: Bark the Polar Bear and Bean the Dynamite. Although it's obvious what animal Bark is, Bean is a duck. He has explosives with him, hence the addition of the word "dynamite."
When the character comes to the level where he/she is the opponent, Robotnik creates a duplicate of the character. For example, Fang plays against a black and white colored Fang in the Casino Night match.
There was a soundtrack released, copyright 1996. It contains all of the songs available on the game, plus a couple of "bonus" tracks.
