Sonic the Hedgehog 2

 

Sonic the Hedgehog 2 is a 1992 platform game developed and published by Sega for the Sega Genesis. It is the second main entry in the Sonic the Hedgehog series, and introduced Sonic's sidekick, Miles "Tails" Prower, controllable by a second player. In the story, Sonic and Tails must stop series antagonist Dr. Ivo Robotnik from stealing the Chaos Emeralds to power his space station, the Death Egg.

Development began in November 1991. It was developed by Japanese and American staff at Sega Technical Institute in California and directed by Masaharu Yoshii and produced by Shinobu Toyoda. The game design was led by Hirokazu Yasuhara and music composed by Masato Nakamura. Art director Tim Skelly designed the appearance of the new 3D special stages based on a tech demo created by Yuji Naka. The staff increased the speed of Sonic the Hedgehog 2 in comparison to its predecessor.

Sonic the Hedgehog 2 sold over six million Genesis cartridges, making it the second best-selling Genesis game behind the original Sonic the Hedgehog. Cited as one of the greatest video games of all time, it received acclaim for its level design, visuals, and music. It has been rereleased on various platforms; a remastered version developed using the Retro Engine released on iOS and Android in December 2013. Two direct sequels, Sonic the Hedgehog 3, and Sonic & Knuckles were released in 1994.
