Sonic the Hedgehog CD,[a] more commonly known as Sonic CD, is a platform video game developed by Sonic Team and published by Sega originally for the Sega Genesis add-on Sega CD in 1993.[3] The game is the only installment in the Sonic the Hedgehog series to have been released for the console. Sonic CD follows the titular Sonic the Hedgehog as he attempts to save Amy Rose and Little Planet from Doctor Robotnik and Metal Sonic. The game features the debut appearances of Amy Rose and Metal Sonic, both of whom have gone on to become recurring characters in the Sonic series. Time travel is a key aspect to both the story and gameplay, with nearly every stage containing four different variations (one for each time period) featuring alternate stage layouts, music, and graphics.

Development of the game began in after the completion of the original Sonic the Hedgehog as an enhanced port of Sonic the Hedgehog 2, but was later split into a separate project. Upon its release, Sonic CD received critical acclaim, with critics praising the game's graphics, gameplay, and audio; some have called it one of the best games in the series.[4][5][6] The game's success has led to it being ported a number of times, first to Microsoft Windows as part of the Sega PC brand in 1996, and to both the PlayStation 2 and GameCube as part of Sonic Gems Collection in 2005. Beginning in the early 2010s, enhanced ports of the game were also released for various other platforms and mobile devices.

Gameplay

Sonic the Hedgehog CD is a platform game in which the player character is the titular Sonic the Hedgehog. The goal of the game is to collect seven Time Stones and defeat Sonic's nemesis Doctor Robotnik. Along the way, Sonic can collect rings, which can protect him if he is hit by an enemy or obstacle, as well as items such as shields, invincibility, and speed shoes. Sonic's gameplay remains similar to that of Sonic the Hedgehog but with the addition of the Spin Dash and the Super Peel Out, which lets him zoom into a quick speed from a standing point, respectively in a rolling or running position. The Super Peel Out is faster than the Spin Dash but leaves Sonic more vulnerable. Each of the game's seven themed rounds is divided into three "zones": two main levels and a boss level.[7]

The main gameplay mechanic that sets Sonic CD apart from other Sonic games is a time travel system that enables players to move between different time periods within each level. By hitting posts labeled "past" or "future" and then keeping a consistently high speed for several seconds, Sonic can move between past, present and future level variants.[8] The time travel posts are only present in the first two zones of each stage; boss zones always take place in the future.[9]

The game contains four different variants of each zone ("past", "present", "good future" and "bad future"), each of which features different graphics, music, and layouts of platforms, enemies, and obstacles. By default, traveling to the future will take Sonic to a "bad future" version of the current level, an industrialized dystopia with scenery themed around neglect and decay, in which enemy robots exhibit signs of degradation.[7] Therefore, players are encouraged to convert each zone's timeline to a "good future": a utopic technogaian scenario in which technology and nature are symbiotically fused into a sustainable, colorful environment, and in which there are no enemy robots.[7] In each non-boss zone, a good future can be attained by traveling to the past: a primitive, vegetation-filled version of the stage with few enemy robots and muted, natural colors. Players must destroy a hidden "robot transporter" in order to obtain a good future.[10] If a good future is achieved in both of a stage's non-boss zones, that level's boss fight will also take place in the good future.

Sonic CD's special stage utilizes the Sega CD's enhanced graphical capabilities

Similar to Sonic the Hedgehog, if a player has more than 50 rings by the end of the act, a giant ring appears that can take Sonic to a Special Stage if he jumps into it. On a three-dimensional plane, the player has a short amount of time to destroy several purple UFOs[11][b] floating around the level. Time is quickly reduced if the player runs through water, though a blue UFO which appears when time is running out can grant extra time if destroyed. If the player is able to destroy all the purple UFOs before the time runs out, a Time Stone is earned. A good ending can be achieved by collecting all seven Time Stones, or by achieving a "good future" in every act.[7] The player will also automatically achieve a "good future" in any level if all the Time Stones have been collected.

Sonic CD contains a "backup save", using the internal Mega-CD memory or a backup RAM cartridge. The game saves after the end of each level (after which, a new level begins) and records the best times of the player in the Time Attack mode. In the 2011 version, the game is saved at the end of each zone. The game also features an instant game over scenario: if the game is not paused and is left alone for three minutes, Sonic will leap off the screen.

In the 2011 version, players are also able to control Miles "Tails" Prower after clearing the game once.[12] He has his moveset from Sonic the Hedgehog 3: as with Sonic, Tails can use the Spin Attack and Spin Dash, and has the added ability to fly and swim, but is unable to use the Super Peel Out and cannot be used to earn achievements.[8] Players also have the option to utilize the Spin Dash physics from Sonic the Hedgehog 2, allowing the player to charge and more quickly use the Spin Dash.[7]

Plot

Sonic the Hedgehog journeys to Never Lake, where, according to legend, an extraterrestrial body known as Little Planet is said to appear on the last month of every year. Upon arriving, he finds the planet tethered to a mountain by a chain and partially mechanized.[13] Sonic ventures into the planet where he discovers his nemesis, the mad scientist Doctor Robotnik, who has led his robot army to the planet and established a base to transform it into a giant fortress. Robotnik has also come to the area in search of the Time Stones - seven jewels capable of time manipulation. Upon discovering Sonic's presence, he dispatches his top robotic enforcer, Metal Sonic, to track him. After following Sonic to a casino, Metal Sonic proceeds to kidnap Amy Rose, a young female hedgehog who had followed Sonic to the area. Sonic is tasked with re-collecting the Time Stones and saving Amy, and repeatedly clashes with Robotnik as he explores the island. During his journey, Sonic uses time travel to go back in time and restore Little Planet to its former self by destroying Robotnik's robot transporters, thus weakening the Doctor's forces.

After chasing Robotnik from his weapons factory,[14] Sonic ventures into the city of Stardust Speedway. Here, he encounters Metal Sonic again, and the two clash as they both try to escape while Robotnik destroys the city. Metal Sonic fails to escape and is severely damaged, and Sonic frees Amy. Sonic proceeds to advance to Robotnik's base at the center of the planet, where he and the Doctor fight a final duel; Sonic manages to defeat Robotnik, causing his base to explode. The ensuing explosion breaks Little Planet free of its tether, and Sonic, Amy, and Robotnik each escape. Two endings exist, dependent on whether or not the player had Sonic gain a "good future" in each level. In the game's "good" ending, Little Planet is returned to its rightful state and leaves Never Lake, illuminating itself in the shape of Sonic's head to thank him. In the game's "bad" ending, Little Planet leaves Never Lake but is left under Robotnik's rule, in a decaying, mechanized state, and Sonic watches the Doctor escape with the Time Stones in hand. In a post-credits scene, time resets, causing Little Planet to reappear at the lake, and Sonic returns to save the land once and for all.[15]

Development

Original version

Development of Sonic the Hedgehog CD lasted two years, and was designed to show the technical features of the Sega CD.[16]

Following the release of Sonic the Hedgehog, lead programmer Yuji Naka had grown dissatisfied with the rigid corporate policies at Sega and moved to the United States to work with the Sega Technical Institute, along with several members of Sonic Team, to develop Sonic the Hedgehog 2. Meanwhile, in Japan, a separate development team headed by Sonic creator Naoto Ohshima handled development on Sonic CD. While beginning development as an enhanced Sega CD port of Sonic 2,[17] Sonic CD was eventually split into a separate game, after lower-than expected sales of the Genesis game in Japan.[18] During development, the concept of time travel was embraced; Ohshima cited Back to the Future as an influence on the mechanic in an interview with Gamasutra. The team developing Sonic CD did not receive as much pressure from Sega as the team developing Sonic 2 did; Ohshima attributes this to the former not being "a numbered sequel".[19] The characters of Amy Rose and Metal Sonic made their debuts in Sonic CD; the two were designed by artist Kazuyuki Hoshino.[16] The game is also the first in the series to feature full motion video cutscenes, which were produced by Toei Animation,[16] as well as voice acting; Sonic exclaims "Yes!" upon gaining an extra life and shouts "I'm outta here!" if the game is left alone for three minutes.[20] Amy can be heard giggling[21] and screaming[22] in certain levels, and Doctor Robotnik can be heard laughing after the credits in the game's "bad" ending.[23]

"R2" is a fan-given name to a level cut from the final version of Sonic CD. Very little is known about the stage, although an official Sega YouTube video shows concept art for it,[24] and the remaining sprites intended for use in the stage were shared by Christian Whitehead in 2013.[25] According to Whitehead, the second segment of the final animated cutscene is actually of R2, hinting that it was scrapped very early in development.[25]

2011 remaster

The 2011 remaster of Sonic CD was developed from scratch by using the Retro Engine created by independent developer and fan[26][27] Christian "the Taxman" Whitehead. Whitehead originally produced a proof-of-concept video of his fangame[27] running on iPhone in 2009, showing the Palmtree Panic stage and additional enhancements, such as widescreen graphics and the ability to utilize the spin dash physics from Sonic the Hedgehog 2.[28][29] Whitehead also designed two additional stages, "Desert Dazzle" and "Final Fever", however, they were not included in the final release.[30][31] The remake was not released on the Wii, as the game exceeded the maximum downloadable size of 40 MB.[32]

Music

There are two different soundtracks for the game, one which was used for the Japanese, European, and Australian releases of the game, and another used for the North American version. The original Japanese soundtrack was composed by Naofumi Hataya and Masafumi Ogata, who had previously worked together on the 8-bit version of Sonic the Hedgehog 2. The theme songs were entitled "Sonic - You Can Do Anything", composed by Ogata and originally written for Sonic the Hedgehog 2,[33] and "Cosmic Eternity - Believe in Yourself", composed by Hataya and sung by singer Keiko Utoku.[34] The North American version was delayed a few months to have a new soundtrack written and produced by Spencer Nilsen, David Young, and Mark Crew. All the music, save for the "Past" songs, which were in sequenced PCM audio rather than Mixed Mode CD-DA, were replaced,[35] and the theme tunes were replaced with "Sonic Boom", composed by Nilsen and performed by a female ensemble called Pastiche.[36]

The 2011 re-release of Sonic CD features both soundtracks. Although the inclusion of the North American soundtrack was initially uncertain due to licensing issues,[37] it was later revealed that the North American soundtrack was to be included, with the option to switch between the two soundtracks. However, "Sonic - You Can Do Anything" and "Cosmic Eternity - Believe in Yourself" were replaced with instrumental versions due to licensing issues.[26] A 20th Anniversary soundtrack CD was released in Japan on November 23, 2011, featuring remastered versions of the original soundtrack, along with the inclusion of "Sonic Boom", and exclusive arrangements by Cash Cash and Crush 40.[38]

Alternate versions and ports

Microsoft Windows

Sonic CD was ported to Microsoft Windows in 1995,[39] before being given a wide release as part of the Sega PC brand, making it the first Sonic game released on personal computers.[40] This version was released in Japan on August 9, 1996, in North America on August 26, 1996, and in Europe on October 3, 1996, and was distributed by SoftKey. The PC version is largely identical to the original Mega-CD release, however, it contains the complete FMV animated intro and ending sequence, and all versions of the game, including the Japanese version, use the North American soundtrack.[41] Despite the improvements in the opening and ending cutscenes, this version is known to suffer from technical issues.[42] This version of the game is only compatible with older Windows 9x-based computers.[43]

Sonic Gems Collection

Sonic CD was planned to be included in Sonic Mega Collection for the Nintendo GameCube, Xbox, and PlayStation 2, but was left out in the final release.[44] However, the game was released as part of the Sonic Gems Collection compilation released for Nintendo GameCube and PlayStation 2 in 2005.[45] The Gems Collection version of Sonic CD is a port of the PC version with improvements made to the game's frame rate, and uses the North American soundtrack.[36] This version of the game was positively received, with Juan Castro of IGN claiming the title "stands out" compared to the other games included in Sonic Gems Collection.[45]

Nintendo DS

Prior to the release of the 2011 version of Sonic CD, Simon "Stealth" Thomley, who assisted in its early development, created an unofficial demo version of Sonic CD for the Nintendo DS. This version features completed Palmtree Panic and special stages, and the option to play as Tails or Knuckles the Echidna. The unfinished proof-of-concept was a specialized, native port written specifically for using the DS hardware, which did not have the raw processing power to handle the generalized Retro Engine's script interpretation and software rendering. It was, however, cancelled due to the DS nearing the end of its life cycle, diminishing the usefulness a light-weight alternative in light of Sega's existing commitment to the Retro Engine version.[46]

2011 remaster

On August 25, 2011, Sonic CD was released on Xbox Live Arcade and the European PlayStation Network on December 14, 2011, followed by the iOS App Store and Android Market on December 15, 2011 and the North American PlayStation Network on December 20, 2011. The PC version was released on January 19, 2012. A Windows Phone version was released in November 2012.[47] Prior to the game's release, Android gaming tablets purchased from GameStop from November 2011 contained the full game.[48] This version allows support for widescreen graphics and spin dash physics from Sonic 2.[28][29] Players are also able to unlock Tails as a playable character.[48] The port features both the original Japanese/European soundtrack and the American soundtrack, as well as achievement and trophy support and iOS features.[49] It game was released on the Ouya console on August 1, 2013. Sonic CD was also released on Apple TV on March 31, 2016. The iOS version was released for free on October 30, 2016. However, the version features in-app advertisements, and users must pay the game's normal price to disable them.[50]

Reception

Sonic CD has received critical acclaim since its release; some have considered the game to be one of the greatest video games of all time.[61] The iOS version currently holds a score of 93/100 on Metacritic, making it the highest rated game in the entire Sonic series on the site.[62]

Reviewers praised the game's high-quality soundtrack and detailed graphics. GamePro called the visuals "brilliantly colorful".[63] Justin Towell of GamesRadar claimed the Japanese soundtrack seems "totally fresh today" in their review of the 2011 version.[9] IGN gave the game an Editor's Choice award, stating the game "looks great" and called the game "so unique, and cool".[8] The game's time travel mechanic has received consistent praise from critics as well. GameSpot claimed the system added "a more satisfying way to play",[7] and Destructoid claimed it added "depth" to game.[54] The 3D special stages have also been praised despite framerate issues,[9] and Allgame noted that Sonic CD was easily one of the best games available for the system.[53]

Awards and honors

Mega placed Sonic CD at #3 on their list of the Top 10 Mega-CD Games of All Time.[4] The game was awarded Best Sega CD Game of 1993 by Electronic Gaming Monthly.[5] In May 2009, GamePro listed Sonic CD as one of the Top 20 Best Platformers: 1989 to 2009, ranking the game in 12th place.[6] In March 2013, the game was nominated for and won the Windows Phone Game of the Year category of the Pocket Gamer Awards.[64]

Sales

The Sega CD version of Sonic CD has sold 1.5 million copies, making it the best-selling game for the system.[65][66] The Android port later received more than 100,000 paid downloads,[67] while the PlayStation 3 version was ranked at the top spot on PlayStation Network's Top Sellers for December 2011.[68]

Legacy

The story of Sonic CD has been adapted in Archie Comics' Sonic the Hedgehog comic book series.[69]

Two characters introduced in the game, Amy Rose and Metal Sonic, became recurring characters in the Sonic series. Metal Sonic later appeared as a major antagonist in Knuckles Chaotix (1995), Sonic Heroes (2003), and Sonic the Hedgehog 4: Episode II (2012), whose story heavily connects to Sonic CD's. [70] Metal Sonic has also appeared in many spin-offs of the Sonic series in cameos or as a playable character. Amy Rose has also gone on to become a character in many subsequent games as well, most notably in Sonic Adventure.

For the series' 20th anniversary, Sega released Sonic Generations, a game that remade aspects of various past games from the franchise. Both versions feature remakes of the boss battle against Metal Sonic.[71] The upcoming 2017 title Sonic Mania will feature an updated version of Stardust Speedway.[72]
