Sonic Generations (ソニック ジェネレーションズ: 白の時空[2] Sonikku Jenerēshonzu: Shiro no Jikū?, lit. "Sonic Generations: White Time and Space") is a 2011 platformer video game developed by Sonic Team and published by Sega for the Xbox 360, PlayStation 3, PC. A Nintendo 3DS version of the game was also released in the same month. The game was made and released to celebrate the twentieth anniversary of the Sonic the Hedgehog series. All versions of this game can be played in stereoscopic 3D, but a 3DTV as well as a pair of 3D glasses are required for the PlayStation 3 and Xbox 360 versions, being the first game of the franchise to support stereoscopic 3D.

The PlayStation 3 version was available to be streamed on the PlayStation 4 and PC via the PS Now subscription service, with PlayStation 3, PlayStation Vita, Sony Bravia Smart TV (2013, 2014, 2015 and 2016 models), Sony Blu-Ray players and Samsung Smart TV support for the service being dropped in 2017. In April 2018, the Xbox 360 version of the game was made backwards compatible with the Xbox One and supports Xbox One X enhanced features.[3]

In Sonic Generations, Sonic celebrates his birthday party with his friends, only for them to be captured by the Time Eater and left trapped in White Space. Teaming up with a younger version of himself, Sonic explores White Space to save his friends, defeat the Time Eater and return home.


Spoiler warning: Plot, ending details or any kind of information follow.

In a past version of Green Hill, Classic Sonic is running until he hears a noise. Suddenly, the mysterious entity known as the Time Eater appears in the sky and the screen washes white.

In the present day, Sonic celebrates his birthday with his friends until the Time Eater disrupts the party, sucking everyone through various "time holes" and scattering them across different points in Sonic's past. Sonic tries to stop the monster, but is easily overwhelmed by its power. After regaining consciousness, Sonic finds himself in a strange dimension known as White Space, a realm where time and space end up after they have been 'erased' by being drained of color and life. Sonic rescues his best friend Miles "Tails" Prower and as they search for their friends, they encounter versions of themselves from the past, referred to as their "Classic" selves. As the two Tails determine that Time Eater's actions are damaging time and space itself, which is why it is white and lifeless, both "Classic" and "Modern" Sonic race through their history, restoring time to normal and rescuing their friends. They also realize at one point that the Time Eater's weakness are the Chaos Emeralds.

After restoring the worlds and collecting all the Chaos Emeralds, they confront the Time Eater, and are shocked (Modern Sonic being annoyed) to find that both Classic and Modern Dr. Eggman are piloting it. Modern Eggman reveals that while drifting through space following the events of Sonic Colors, he discovered the Time Eater, thinking about the idea to use its powers and decided to use it to alter the past and undo his previous defeats, but he needed someone just as smart as him to help modify the Time Eater for combat, which was why he had it abduct his Classic self earlier. Although the Time Eater manages to nearly defeat the two Sonics, the support of their friends and the power of the Chaos Emeralds allow them to transform into Super Sonic and Classic Super Sonic, and confront both versions of Eggman. Despite attacking with missiles, warping arms and slowing down time, the Sonics penetrate the Time Eater's core, destroying it. The heroes return to the present and continue celebrating Sonic's birthday. After the party, Classic Sonic and Classic Tails travel back to their own world as everyone bids their farewells.

A post-credits scene shows the two Eggmen lost in White Space. The two argue as they search for an exit, discuss whether or not they ever defeat Sonic and contemplate if they should go back and get their teaching degree as opposed to continuing their misdeeds.

Sonic Generations is a platforming video game, with bits of gameplay taken from past Sonic games. The player takes control of either Classic Sonic or Modern Sonic, each with their own abilities and levels. The game is divided into nine stages, which are all taken from past Sonic games, which are composed on two Acts, the first one with the player controlling Classic Sonic, and the second one having them playing as Modern Sonic. In addition, the player may also unlock boss stages and Challenge Acts, both of which have to be completed in order to progress with the story, although most Challenge Acts are optional.

The goal of Sonic Generations is to beat the aforementioned Acts in the least amount of time as possible. In these Acts, the player might find Rings scattered, which serve as the playable character's main defence against obstacles. If the character is hit while having at least one Ring with them, they will survive the attack. On the other side, if the player does not carry any Rings when suffering damage, they will lose a life, or get a Game Over if they run out of lives. In the former's case, the player will respawn at the latest Star Post they touched, or at the start point of the Act if they did not touch any Star Post.

Classic Sonic has a 2.5D side-scroller gameplay, the same as that from the 2D Sega Mega Drive Sonic games, though with some modifications to be more adapted to the newer level design. As with the aforementioned games, Classic Sonic can run and jump as his most basic abilities. In addition, he can also Spin Dash while standing still to be launched at incredible speeds. Classic Sonic's Acts end when he touches a Goal Post at the end of the stage.

Modern Sonic's gameplay resembles that from both versions of Sonic Unleashed and the Wii version of Sonic Colors. Occasionally, the camera will shift between a side-view angle and a third-person angle, offering a 2.5D side-scroller gameplay and a 3D gameplay respectively. Like Classic Sonic, he can run and jump, those being his most standard abilities. However, he can also Boost to run at incredibly high speeds and destroy almost everything that is in his way, though this ability is limited and cannot be performed if the player's Boost Gauge is empty. Sonic can also perform a Homing Attack to reach nearby targets with ease, and slide to pass through small spaces with ease. Modern Sonic's Acts end when he touches a Goal Ring.

The Skill Shop allows players to use points earned from high scores to unlock upgrades such as abilities, shields, and even the original Sonic the Hedgehog Genesis game (on PlayStation 3/Xbox 360 only). Completing challenges, as well as finding Red Star Rings hidden in each of the main Acts, unlocks additional skills, as well as bonus concept artwork and music. The music can then be played in any stage, challenge, or boss fight. There are also online leader-boards for two modes: Ranking Attack, which challenges players to obtain the best time and score on each level, and 30 Second Trial, which challenges players to see how far they can get through a level in thirty seconds.

Sonic Boom

The Sonic Boom logo.

A Sonic Generations demo was playable at 2011's E3 Expo, under the name "Sonic Boom" (no relation to the animated series.) It was the first major American Sonic event, being hosted by Sega, and took place on June 8, at 6pm PT. At E3, Sonic Generations was playable in both HD and 3DS versions. Although only Green Hill was playable for the console versions, City Escape was shown. There was also a Birthday Song for Sonic sung at Sonic Boom and the ending of the song, "Happy Birthday Sonic!" was heard in Sonic Generations.[4] This song appeared at the Tokyo Joypolis event and at the Summer of Sonic event in London. It appeared at the Gamescom 2011 event in Germany, and at TGS (Tokyo Game Show) 2011.

Demo release

The Australian government’s OFLC rated a multi-platform demo release of Sonic Generations and Sega formally announced at E3 that they would release a demo for PSN and Xbox Live on Sonic's 20th Anniversary, 23 June. The demo only contained Green Hill, and only the Classic Sonic playthrough. However, this demo also contained many unused files that revealed much about the full game, notably the stage list. The demo was only available until 12 July, at which point it was no longer available, including for players who had already downloaded it; the file essentially locked itself. In the Xbox Live version, one has to be an Xbox Live Gold Member to download the demo although in the PSN version, a PlayStation Plus Subscription is not required. The name of the demo is "Sonic Generations Green Hill Zone Demo #1", indicating another demo was on the way. Sega confirmed on their blog a second demo released in Europe for PSN and Xbox Live on October 18 and was released in North America for PSN on 25 October.[5] The demo contains both classic and modern Sonic playable in Green Hill and has no time limit.


Main article: Skills

Skills are items both Sonics can use in acts and some missions. They can be unlocked by doing certain Challenge Acts, buying them at the Skill Shop, or collecting five Red Star Rings in an act. Some Skills are exclusive for either Classic or Modern Sonic, and cost a number of skill points to be equipped. They do not work during Challenge Acts or Boss battles though.

30-second Trial

Sonic Generations 30 second trial.png

In this mode, the player has to get as far as they can in a stage in 30 seconds. After time runs out, a sign post is placed in the spot where the player is standing. In other cases if they reach the goal before the time runs out (which is only possible via time hacking), the mode abruptly ends without the score saved. They have the option to try again or continue playing to find the sign posts of their friends who are ahead or hopefully behind them. They can upload their score online and see which of their friends made it the farthest in one specific level.

Time Attack

In this mode, the player can see how fast he/she can clear a stage, a rival, or a boss fight, and can share their time in online leader-boards. In the console version, Time Attack can only be done online, and only the eighteen main Acts can be played for a top time.

Bosses and Rivals



Final Boss



Classic Sonic is silent throughout the game, but still shows his personality through his actions and gestures. Aaron Webber mentioned in an interview, that if anyone were to be Classic Sonic, it would be Jaleel White. Aaron had to make a choice whether Classic Sonic would be voiced by Jaleel White or have no voice at all. Aaron also mentioned that he grew up with the classic cartoons of Sonic like Adventures of Sonic the Hedgehog, and he thought Jaleel White did a fantastic job.

For the first time, voice overs exist not only for English and Japanese, but also for German, French, Italian and Spanish. The French voice cast (except for Vector) and the German voice cast (except for Shadow, Cream, Vector, Espio, Charmy and Rouge) all reprise their roles from Sonic X.

Cover of Blue Blur: Sonic Generations Original Soundtrack.

The soundtrack for Sonic Generations is called "Blue Blur: Sonic Generations Original Soundtrack" which includes the Soundtrack for both the HD and Nintendo 3DS versions of Sonic Generations.[7][8]

The music in the game was remixed by Jun Senoue and Tatsuya Kozaki, with guest remixes done by Tomoya Ohtani, Kenichi Tokoi and Naofumi Hataya (who remixed the classic versions of the Genesis stage themes), among others.

Unlockable music

Music can be unlocked by completing some missions or collecting a number of Red Star Rings. The player can view his/her unlocked music by going to the collection room. The music for each stage in the game can be replaced by any unlocked music. In the 3DS version, they can only be heard in the extras menu.

There is a total of 50 unlockable songs.


Inside the media room, there lies a Statue Room where the player can collect many characters with various codes, even the regular enemies and four characters who didn't appear in the game otherwise. The room is accessible by holding Back (Xbox 360 and PC)/Select (PS3) while in the collection room. These statues are:


Stages are divided into three eras, each representing games from a different generation of video game consoles. The first era represents games from the fourth generation, on the consoles the Sega Genesis/Mega Drive and Sega CD. The second era represents games from the sixth generation, on the consoles the Dreamcast and GameCube/Xbox/PlayStation 2. The third era represents games from the seventh generation, on the consoles PlayStation 3/Xbox 360, and Wii. The player collects the Chaos Emeralds by defeating the three bosses and three rivals, plus one more that is automatically given when both Acts are cleared on Planet Wisp.

The level progression for Classic and Modern Sonic are kept separate within eras.

First era

Classic Sonic in Chemical Plant.

Second era

Modern Sonic in City Escape.

Third era

Modern Sonic in Planet Wisp

Classic Sonic battling the Death Egg Robot.

Development of Sonic Generations began in 2009 when Takashi Iizuka realized that there was no anniversary game planned for 2011. His idea for a tribute was accepted by Sega and developments began. Sega held an internal poll for employees of Sega, including Sega of Japan, America, and Europe asking what their favorite levels from the Sonic series were. After ranking the most popular levels, a website was launched holding another poll asking the opinions of fans of the series.[9]

In late 2010, rumors of a Sonic Anniversary game surfaced online.[10] The rumors told of a game that would potentially feature remakes of levels from throughout Sonic's history in 2D and 3D. The game was alleged to be released on all major game consoles at the time: PSP, PS3, Xbox 360, Wii, and DS.

On 18 April 2011, Sonic Generations was finally announced for the PS3 and Xbox 360. A GameStop release list printed on 7 May 2011 showed a 3DS port of Generations with a tentative release date of 31 December 2011. Later in the month, a Sega-Sammy earnings report listed 3DS and PC versions of the game; however, a revised version of the report no longer listed either version.[11] The June 2011 issue of Nintendo Power finally confirmed a 3DS version of Sonic Generations.[12] It contained an in-depth preview and interview with Takashi Iizuka.

Sega officially announced a PC version of the game on 11 October 2011.[13] This version was outsourced and developed by the British company Devil's Details.

Sonic Generations has sold nearly over 3 million copies worldwide as of April 30, 2014,[43] making it the fifth best selling Sonic game to date, behind Sonic the Hedgehog (over 4 million), Sonic Unleashed (also over 4 million), Sonic the Hedgehog 2 (over 6 million), and Sonic Heroes (also over 6 million).

The console and PC versions received generally positive reviews. Aggregating review websites GameRankings and Metacritic gave the PlayStation 3 version 79.29% and 76/100,[14][20] the Xbox 360 version 78.67% and 77/100,[15][18] and the PC version 78.43% and 77/100.[16][19] IGN gave the game a score 8.5 out of 10 and an Editor's Choice award, praising the overall gameplay and the level design, while criticising some occasional control issues and limited boss battles.[34] Computer and Video Games gave it a 7.5/10, praising the balanced design but criticizing the frame rate of the graphics.[44] gave the game a "B" score, praising its variety, fun-to-play levels and interesting set-pieces, while criticizing some on-rails sections and occasional framerate drops.[22]

PlayStation Official Magazine gave it an 8/10, calling it "a masterpiece of platform game design."[45] GameTrailers gave the game a score of 8.1, calling it "the best Sonic game in over a decade."[32] GamesRadar gave the console version 8/10, calling it "the best Sonic game since Sonic 2,"[30] while they gave the 3DS version 7/10, praising its level design and optional missions but criticizing its short length as well as the fact that modern Sonic is restricted to a 2D plane of movement.[17] Eurogamer, however, was less enthusiastic, writing that "Sonic Generations still doesn't do much to dissuade us that the hedgehog's best days are distant memories, but at least it is a worthy tribute to them."[24] The most positive review on Metacritic is a 9.5/10 from PALGN, which argues that the game is significantly better than Sonic Unleashed, Sonic Colors, and Sonic the Hedgehog 4.[38] Game Informer's Tim Turi was more critical of the game, criticizing Sega for "...shoehorning recent Sonic games, no matter how awful, into the 20-year timeline." He felt that such stages served "...only to remind you of how far the series has fallen from its original form."[27] Famitsu praised the speed and addictiveness of the gameplay as well as the bonus material, while emphasizing that "you do need a certain amount of ability to play it the way it was meant."[25] Empire gave the game 4/5 stars, saying "Generations is a nostalgic joy that captures the dizzying speed and psychotic pace that made Sonic's original romps console classics."[40] GameSpot's Nathan Meunier praised Generations for its "impressive level designs," "gorgeous" visuals, "epic boss encounters," and high replay value.[29]


Archie Comics produced a video game tie-in for Sonic Generations in Sonic the Hedgehog Issue 230.

A short manga for Sonic Generations was released in Japan. It is presented in a similar format as the Sonic World Adventure manga and the Sonic Colors manga.


  • The internet poll asking fans what their favorite stages from each mainline Sonic game were also listed stages from Sonic and the Secret Rings and Sonic and the Black Knight, suggesting that at one point in development, stages from both games were meant to appear in Sonic Generations but were scrapped later on.
    • Because Sonic Colors was not announced yet at the time the poll was released, none of its stages appeared in the poll.
  • There are some differences between the console and the PC version of Sonic Generations. First of all, the PC version has more shadows and the colors are slightly less vibrant than on the console version. The maximum framerate for the PC is 60 FPS while it is locked to 30 FPS on consoles. The loading times are also greatly decreased in the PC version, and it lacks the Sega Genesis Controller.
    • However, the Sega Genesis version of Sonic the Hedgehog runs at 60 FPS in the console version.
    • Also, in the PC version, all cutscenes, including boss intro cutscenes and boss outro cutscenes as well as the Saving A Friend cutscenes, are locked at 30 FPS.
    • In the PS3 version, Motion Blur was disabled.
  • The textures for Planet Wisp's environment map are actually screenshots of the team's dev program.
  • All Challenges against friends in the first era are races.
    • Tails is the only character who races against Modern Sonic. Knuckles and Amy race against Classic Sonic.
  • This is the first 3D Sonic game not to have a unique theme song.
  • Like Sonic Unleashed (Wii/PS2), while using the Boost on a Dash Panel, Sonic performs a Spin Dash animation.
  • In both Sonic & Knuckles and Sonic Generations, the Death Egg can be seen in the background of Sky Sanctuary. In Sonic & Knuckles, the next level is Death Egg Zone, and in Sonic Generations, the next level is the fight against the Death Egg Robot, which coincidentally takes place in the Death Egg.
  • This is the first time Modern Sonic gets Boost Energy from both Rings and Enemy Power in a handheld console.
  • The game's box artwork has a white colored accent on top and bottom.
  • The rivals in this game appeared as playable characters in Sonic Rivals.
    • Knuckles is the only rival from Sonic Rivals that is a friend in Sonic Generations, as the others are all rivals that battle Sonic.
  • The drowning countdown starts at 4 instead of 5, although a different tone is played before the countdown starts. Underwater warning beeps are also much more prominent.
  • After Sonic saves Tails, he makes a reference, saying that the stage was "awfully familiar," followed by Tails saying that he does not recognize the stage at all. This most likely references the fact that Green Hill Zone is a Sonic the Hedgehog stage, and Tails was introduced in Sonic the Hedgehog 2.
  • This is the second 3D Sonic game where Eggman is the final boss.
  • Out of all 9 main stages, 3 of the stages are based on the first levels of their respective games (Green Hill, City Escape and Seaside Hill). To a lesser extent, Crisis City is also considered a starting level (but in the case of Silver, and not Sonic) and Speed Highway (Knuckles' first level). It can also be said that Radical Highway is a first level of sorts due to being Shadow's first level in Sonic Adventure 2.
  • This is the second main 3D game to have someone (Classic Tails, specifically) call Dr. Eggman the name "Dr. Robotnik," the first being Sonic Adventure, which was the game where Eggman got his nickname.
  • Classic Metal Sonic's artwork pose is similar to Shadow's.
  • This is the second 3D Sonic game in which the player starts a new game and are taken to the first stage, rather than showing the cutscene first. The first game to do this was Sonic Colors.
  • "History of the 1st Stage: White Edition" and "History of the 1st Stage: Blue Edition" are the Japanese pre-order bonuses for the console/PC and 3DS versions respectively, not the soundtrack as originally thought. They are both disks with separate soundtracks that consist of music from the first stage of the franchise.[46]
  • Coincidentally, Shadow's line from his own game, "Where is that damn fourth Chaos Emerald?" is also referenced, as he has the fourth Chaos Emerald of the game.
  • Takashi Iizuka said that three original taglines for the game were "Blast with the past," "Déjà Blue," and "A speedy trip down memory lane."
  • With the exception of the Egg Dragoon, all of the bosses in the console/PC version can only take half the amount of hits the 3DS version's bosses can (four in the console/PC version, eight in the 3DS version).
  • When playing the original Sonic the Hedgehog on the Sega Genesis, a top score and top time can be recorded. However, the player must finish the game to save said data.
  • In the hub world, Sky Sanctuary has trees with grapes in them. Knuckles' favorite food is stated to be grapes in the Sonic the Hedgehog 3 manual, and Sky Sanctuary is also where Knuckles is saved in Sonic Generations.
  • When an S rank is achieved on one of the levels or bosses, the text color of the title of it turns golden.
  • The unlockable music list has slight remixes of the Classic Sonic songs (mainly Sonic the Hedgehog 3 and Sonic & Knuckles).
  • After a stage is restored, a level's background noise can be heard, faint from the normal background music. This is easily heard when muting the music:
    • Green Hill, sounds of the waterfalls and bird songs are heard.
    • Chemical Plant, sounds of construction are heard.
    • Sky Sanctuary, loud bird songs are heard
    • Speed Highway, moving, honking cars are heard.
    • City Escape, crowds talking are heard.
    • Seaside Hill, sounds of a beach are heard.
    • Crisis City, sounds of volcanic explosions are heard.
    • Rooftop Run, faint crowds are heard.
    • Planet Wisp, a mix of bird songs and construction is heard.
  • The Death Egg Robot is the only boss originally fought by Sonic as himself. Perfect Chaos was fought by Super Sonic and the Egg Dragoon was fought by the Werehog.
  • Classic Sonic, in his super form, retains his black eyes (like in Sonic the Hedgehog 2) instead of changing to the turquoise eyes from Sonic 3 & Knuckles.
  • This is the second game to use skill customization, the first being Sonic and the Secret Rings.
  • This is the first modern Sonic game on a handheld Nintendo system not to have Boost Mode. It is also the first where boosting through enemies is "seamless," not causing a split-second pause like in Sonic Unleashed (Wii/PS2) or the DS games.*All the rivals are hedgehogs or robotic copies of hedgehogs.
  • Even if the player lives in the United States, the PC version downloadable from Steam is based on the PAL version. This is confirmed due to "Colors" being spelled "Colours".
  • In the Unlockable Songs list, Hydrocity Zone is spelled "Hydro City Zone" instead.
  • During the credits, the original levels from each game play along with the music medley as a tribute to the original games. The following game versions were used: the original Japanese Sonic Adventure release on Dreamcast, Sonic Adventure 2 Battle on GameCube, the PC version of Sonic Heroes, the PS3 versions of Sonic the Hedgehog (2006) and Sonic Unleashed, and the Wii version of Sonic Colors. There are no obvious indications if the Genesis/Mega Drive games are originals or direct emulations (or even Sonic Jam). Oddly enough, even though the credits use the revised Japanese version of the original Sonic the Hedgehog, the unlockable emulation in console versions is the original American release.
  • Sonic Generations was held on a 66% discount on Steam via PC Download as a Daily Deal due to the large amount of downloads.[47]
  • In Sonic the Hedgehog 2, Chemical Plant Zone is the second stage. In this game, coincidentally, Chemical Plant is the second stage.
  • In the Collection Room, two of the cutscenes the player can view are both named Eggman Abducted, both being the cutscene after beating the Death Egg Robot and the Egg Dragoon.
  • The rival and boss battle of the second era mainly used the Boost throughout the fight which was introduced in the third era.
    • In contrast, the rival and boss battle of the third era mainly used the Homing Attack and Auto-Running which were introduced in the second era games.
  • Not long before the release date of Sonic Generations, Sega sponsored a skateboarding sporting event that took place in Venice Beach of California named "Sonic Generations of Skate".
  • Four of the levels were the first levels in their original games. Green Hill Zone, City Escape (Hero Story), Seaside Hill (every team except Team Rose) and Crisis City (Silver's Story).
  • The Silver the Hedgehog boss battle is the only recreated/reimagined boss in the game that was not based off a second-to-last or final boss. Metal Sonic, Egg Emperor, and the Egg Dragoon are boss battles that are second to last while the Death Egg Robot, Big Arm, Shadow the Hedgehog (final boss of Hero story in Sonic Adventure 2), and Perfect Chaos are all final bosses to their story modes and games.
  • When looking at the models on the character profiles, both Silver and Rouge strike the same poses.
  • If the player views the entire White World in a 3D model viewer, if they zoom out and look around, the entire Crisis City level will be there.
  • Despite the game giving Super Sonic a theme, (it being an instrumental remix of the Sonic the Hedgehog 4: Episode I theme) it only plays during the final phase of the Time Eater boss fight, and a variant of it plays in the cutscene prior to the fight.
  • When booting up the PS3 version of this game, some of Sonic's sprites from Sonic the Hedgehog are used before the Sega motto loads up.
  • The physics engine is actually a modified version of the Sonic Unleashed engine. Hacking into the game can restore properties found within Sonic Unleashed, including light shafts, motion blur, and directional shadows.
  • On July 14, 2015, Sega posted a video of the cutscene played before the final battle, adding in footage from a motivational speech video featuring actor Shia LaBeouf. That speech came from #INTRODUCTIONS.[48]
  • It should be noted that Classic Sonic's stages, are in fact 3D and the creators have just changed the in-game camera to be in 2D perspective.
  • In the "Ending" cutscene of the HD version, the dialogue between both Classic and Modern Tails is different between the English and Japanese scripts. In the English script, Classic Tails asks Modern Tails where Sonic puts all of his collected Rings. In the Japanese script however, Classic Tails asks his Modern self how he could add legs to Sonic's Tornado model.
  • Sonic Generations is the fourth main game to have all four hedgehog main characters presented (Sonic, Amy, Shadow and Silver). The others before this being Sonic the Hedgehog (2006), Sonic Rivals and the Nintendo DS version of Sonic Colors.
  • This is the only game dubbed in French, Spanish, German, and Italian to not have the Wisp announcer voiced in those languages, with the game using its English voice instead.
