Sonic the Hedgehog CD

***Sonic the Hedgehog CD*** (***Sonic CD*** for short) is a platform video game created by Sega. It is part of the _Sonic the Hedgehog_ series. It was released for the Sega CD game console in 1993. In chronological order it is after the first game and "before the sequel."  The game involves the use of a time travel system that allows Sonic to travel to both the past and the future in a level. Each zone has four variants: the "past," the "present," the "good future," and the "bad future." Each has different graphics, music, enemies, and obstacles. The game introduces two characters to the _Sonic the Hedgehog_ series: Amy Rose, a pink female hedgehog who is in love with Sonic, and Metal Sonic, an evil robotic version of Sonic.

## Gameplay

_Sonic CD_ is similar to the original game; the player goes through lots of levels called "zones" to battle Dr. Robotnik every 3 acts. This game adds time travel; Sonic can hit a time post and keep running fast to go to the past or future. To make a good future, the player must explore each zone's past version to find a generator and destroy it.

### Release and translation

_Sonic CD_ was released in Japan on September 23, 1993. It was released in Europe in October 1993. The game was released in North America in November 1993.

### Remake

In 2011, for the 20th anniversary of _Sonic the Hedgehog_, indie game developer Christian Whitehead made a new version of the game for Xbox 360, PlayStation 3, Windows, iOS and Android. The port was a success, and Whitehead was later asked by Sega to remake _Sonic 1_ and _Sonic 2_ for mobile devices. Whitehead would go on to help make _Sonic Mania_. Those ports of _1_, _2_ and _CD_ would be used in _Sonic Origins_.
