Sonic the Hedgehog 2

***Sonic the Hedgehog 2*** (also called ***Sonic 2***) is the second video game in the _Sonic the Hedgehog_ series. It is a sequel to _Sonic the Hedgehog_. It was made by Sonic Team and published by Sega for the Sega Genesis in 1992. Unlike the first game, it has a half-pipe special stage and has seven Chaos Emeralds instead of six. It also introduces Miles "Tails" Prower.

Development of the game began in November 1991, five months after the first game released. The game was developed by both Japanese and American staff at Sega Technical Institute.

## Plot

Dr. Robotnik has begun making his ultimate weapon: the Death Egg. He searches for the seven Chaos Emeralds, which are hidden on West Side Island, to use as the spaceship's power source. Sonic goes to West Side Island to chase Robotnik down, and meets a two-tailed fox nicknamed Tails.

To stop Robotnik's evil plans, Sonic and Tails travel through 11 zones: Emerald Hill, Chemical Plant, Aquatic Ruin, Casino Night, Hill Top, Mystic Cave, Oil Ocean, Metropolis, Sky Chase, Wing Fortress and finally the Death Egg. At the end of the game, after Sonic defeats Robotnik and his Death Egg Robot, Tails saves Sonic from falling to the ground with his plane, the "Tornado". The Death Egg crashes into Angel Island, setting up the events of _Sonic the Hedgehog 3_.

## Gameplay

The gameplay is similar to the first _Sonic the Hedgehog_ game; the player can run, curl up into a ball and jump, and perform a new move, the Spindash. The Spindash is a move where Sonic can curl up, gain energy, and roll at high speeds. Tails follows Sonic through most of the levels so he can help pick up rings and destroy enemies.

When the player touches a checkpoint with at least 20 rings, they can go to a special stage where they must collect as many rings as they can while dodging bombs. If the player wins a special stage, they earn a Chaos Emerald. Getting all seven lets the player turn into Super Sonic, a form that makes Sonic invincible and lets him run faster and jump higher. Using Super Sonic drains one ring every second, and hitting 0 will turn Sonic back to normal. Getting all seven emeralds also unlocks the good ending.

## Development

After the release of the original _Sonic the Hedgehog_, creator Yuji Naka quit Sega due to disagreements over corporate policy. Mark Cerny, who had recently created Sega Technical Institute (STI) in California, met with Naka in Japan. He offered Naka a higher salary and more creative freedom if he joined STI. Naka agreed. Hirokazu Yasuhara, the lead level designer of _Sonic the Hedgehog_, also decided to join STI.

## Reception

Because of the popularity of its predecessor, _Sonic the Hedgehog 2_ already had a fanbase waiting for its release. The game received a lot of praise, and it was a bestseller in the UK charts for 2 months. As of 2006, the game had sold over 6 million copies. This makes it the second best-selling game on the Sega Genesis.

_Electronic Gaming Monthly_ said it was the best Genesis game of 1992.

The most common criticisms were about the two-player mode, a first for the series.
