Sonic the Hedgehog 3 is a platform game developed by the Sega Technical Institute. As part of the Sonic the Hedgehog series, its story directly follows that of Sonic the Hedgehog 2, which ended with Sonic overthrowing Dr. Robotnik with the help of his companion, Miles “Tails” Prower. Unfortunately, Dr. Robotnik’s Death Egg was not completely destroyed, and can be found in the Floating Island. Dr. Robotnik aims to recover the Death Egg by obtaining the Chaos Emeralds, which he tries to do by abducting animals and turning them into Badniks.
The object of the game is for players to defeat Dr. Robotnik by spinning through six zones and collecting rings. Players have the option to take either Sonic or Tails’ character, or play as both. The six zones feature two acts apiece, and end with the player meeting a different boss. To earn points, the player has to hit a falling board before they hit the ground. In this game, players also can save their progress and then go back to the last zone they completed. The character of Sonic has special skills, which include doing a shield move that increases his attack range and provides him with protection. On the other hand, Tails is able to swim underwater or fly in the air for a short period. Moreover, players can go to special stages wherein they can find giant rings.
