Sonic Generations (ソニック ジェネレーションズ:ブルーアドベンチャー[1] Sonikku Jenerēshonzu: Ao no Bōken?, lit. "Sonic Generations: Blue Adventures") is a 2011 2D platformer video game developed by Dimps and published by Sega for the Nintendo 3DS. A loose adaptation of Sonic Generations for the console/PC, it serves as the celebration for the twentieth anniversary of the Sonic the Hedgehog series.

In Sonic Generations, Sonic and Tails get kidnapped by the Time Eater during Sonic's birthday. Trapped in White Space, Sonic and Tails team up with younger versions of themselves to get out of the dimension and save the world.


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 version 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.[2] The June 2011 issue of Nintendo Power finally confirmed a 3DS version of Sonic Generations.[3] It contained an in-depth preview and interview with Takashi Iizuka.

The 3DS had minor story changes as well. The writers for the story are credited as Ken Pontac and Warren Graff of Happy Tree Friends fame. They also worked on Sonic Colors and MadWorld. Tetsu Katano, who directed Sonic and the Black Knight and did work on the Adventure series, directed the 3DS edition. Like Sonic Colors (DS), Sonic Team and Dimps co-developed the 3DS edition.


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

The Time Eater attacks.

The story begins with Classic Sonic in Green Hill. After completing Act 1, a purple vortex in the sky appears and surprises Classic Sonic. After that, it goes all the way to the present day and Sonic is invited to a birthday party by Tails. However, Sonic arrives early, so Tails tells him to wait. But then a vortex sucks Tails into it. Sonic jumps in but is "attacked," though he manages to get in anyway. Sonic sees a white world and wonders what's going on. Modern Sonic rescues Tails after restoring Green Hill, and Tails tells him that he sees a big city in nighttime and a giant mushroom, so Sonic decides to go check those places out, being followed by Classic Sonic, who is believed by Tails to be Modern Sonic.

After restoring Casino Night, Tails informs Sonic that he feels like he has been there and Sonic mentions that he had some sort of "déjà vu" of that place too. After restoring all of the zones in the first era, the Boss Gate opens and Sonic enters it. He then sees Classic Sonic through a glass, thinking that it is a mirror. Then, both Sonics hear Eggman's voice, and Classic decides to follow the voice through a portal, but Modern was unable to get there in time. After entering the portal, Classic Sonic meets with Metal Sonic and races him. After winning, Classic Sonic meets with Classic Eggman on his giant robot, the Big Arm. After the boss fight with the Big Arm, Classic Eggman is kidnapped by the Time Eater and the two Sonics and the two Tails meet. The Tails' explain that they are traveling through time and space. Classic Sonic then learns the Homing Attack after Modern Sonic used it on some Spinners.

After clearing the second era, which is comprised of Emerald Coast and Radical Highway, the Sonics go to the boss gate and Modern Sonic tells Classic Sonic that he's going to take care of it. After beating both Shadow and the Biolizard, Tails does some modifications to Modern Sonic's shoes so he can do the Stomp.

After the third era, comprised of Water Palace and Tropical Resort, Sonic meets with Silver, and then Modern Eggman again on his Egg Emperor. After the fight, Eggman is kidnapped by the Time Eater again.

After restoring all the levels and collecting the Chaos Emeralds, the Sonics go to fight the Time Eater who turned out to be some sort of monster being controlled by both Classic and Modern Eggman, and from seeing both Tails defend the Sonics from the monster, the Chaos Emeralds allow the Sonics to go Super.

After defeating the Time Eater, both Sonics and Tails return to the place where the party was going to take place, and Modern Sonic starts eating his chili dog. However, Classic Tails realizes that the vortex to their world is closing, so he and Classic Sonic have to go back. Just before leaving, Classic Sonic shows Modern that he is learning the Boost as well. After telling him to have a great future, Modern Sonic says goodbye to Classic Sonic and he, along with Classic Tails, return home.

In the post-credits scene, both Classic and Modern Eggman are trapped in White Space, and argue with each other. The real difference is that a teaching degree is not mentioned, and it simply ends with Classic Eggman asking his future self what time it is a second time.


Sonic Generations is a 2D side-scrolling platforming video game, which plays similar to past 2D games such as the Nintendo DS version of Sonic Colors. The player can play as either Classic Sonic or Modern Sonic. Sonic Generations has seven stages, three of them taking place in the Classic Era, two in the Dreamcast Era and other two in the Modern Era. Each of them is divided into two Acts. The first Acts have Classic Sonic as the playable character, while in the second Acts, the player plays as Modern Sonic.

Classic Sonic's gameplay is similar to that from the Sega Mega Drive titles. He can run, jump and perform an Spin Dash as his basic moves. His Acts end by rotating a Goal Plate showing his face, similar to the earliest Sonic games.

Modern Sonic's gameplay resembles that from the Nintendo DS version of Sonic Colors and Sonic Rush. As with Classic Sonic, he can run and jump, though he can also slide to pass through small areas, and Boost to become an almost unstoppable projectile that can destroy obstacles. His Acts end by touching a Goal Ring, similar to past 3D games.

In Sonic Generations, the player can find many Rings, which serve as the playable character's main method of protection. If the player is attacked while they are having at least one Ring, they will survive with the cost of losing all Rings. However, when they are attacked without having Rings, they will lose a life, or get a Game Over if they do not have any lives left.

Special Stages

Special Stages appear as an updated version of the ones from Sonic Heroes. These are unlocked automatically upon completing both Acts of a stage, but do not have to be beaten right away. A Chaos Emerald will be achieved if the stage is completed; however, Super Sonic is exclusive to the final boss, unlike in the console and PC versions.

Other modes

Profile card

The profile card shows the player's user name, their rank (from Beginner to Grand Master), how many years have passed since they became a Sonic fan, their favorite Sonic game, as well as their favorite character, their Mii, and the points it has. On the back (the player can turn the card by pressing the R button), it shows the progress they had in the story, how much they had unlocked in the Collection Room, how many missions they had unlocked, how many rings had been collected, their play time, and all of the ranks the player has achieved on the levels.

The player can also unlock card patterns for it by leveling up the card. The card patterns were taken from different Sonic games, including all the ones that are represented in Generations. There are patterns of games such as Sonic 3D, Sonic the Hedgehog Spinball, Sonic the Fighters, Sonic Riders and Shadow the Hedgehog. Some of Sonic's transformations, such as Excalibur Sonic and the Werehog, receive a card pattern.

When a card is leveled up two ranks, the card changes to a new color. For example, when a card is Rank Beginner (second-lowest rank), the card's color is yellow, but if the player reaches the next rank (Intermediate), the card turns orange. Once the player has reached the Grand Master Rank, the card turns silver and has a shining effect. When the player reaches the final rank, Legendary (999999 points), the card turns golden and sparkles.

The ranks are:

  • Novice (Yellow)
  • Beginner (Yellow)
  • Intermediate (Orange)
  • Skilled (Orange)
  • Advanced (Red)
  • Expert (Red)
  • Pro (Blue)
  • Master (Blue)
  • Grand Master (Silver)
  • Legendary (Golden)

Versus Mode

The menu of the Versus Mode.

Sonic Generations features a local wireless and Wi-Fi 2-player race mode, where the player can use Download Play to send a signal to another 3DS user (though both players must have a copy of the game), or challenge the world by using the Wi-Fi connection. There are also online leader-boards between their races and world-wide races. By playing online races, one can earn points and card patterns for their profile card, and after playing more online races, the player can unlock extra content in the collection room, as well as some of the 100 extra missions.

Also by playing online races, the player can obtain a special skill to use in the main game (the player can only get one skill per day). The skills are:

To use a skill, the player must press the L button or touch the skill icon on the touch screen.


Example of a Profile Card.

StreetPass is used to unlock special content and challenges, and is activated when someone with a 3DS passes by someone else with a 3DS. The player can also use the Nintendo 3DS's "Play Coins" (earned by using the pedometer) to buy content such as new missions (which usually cost five Play Coins each) in case one is unable to StreetPass. The player can also unlock extra content by playing online. With StreetPass, the player can exchange their profile card with other players. Once the player StreetPasses somebody, their profile card gets upgraded in various ways.[4]

Time Attack

Main article: Time Attack

In this mode, the player can see how fast they can clear a stage, a rival, or a boss fight, and can share their time in online leader-boards. All stages can be played for a top time, and 300 Supporter Points (for the player's profile card) are awarded for each time submitted to the leader-boards.


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 and German voice cast (except for Shadow) 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 console/PC and Nintendo 3DS version of Sonic Generations.[5][6]

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

Unlike the console/PC version, which allows unlocked songs to be played in regular stages, unlockable music can only be heard in the extras menu in the 3DS version. Additionally, the 3DS will continue to play the tracks in sleep mode if headphones are connected.

There is a total of fifty unlockable songs.


In the 3DS version's collection room, there's a section called "Models" which is basically the same thing as the statue room from the console/PC version. However, the statues are unlocked by doing the missions, rather than using special codes. It should be noted that all of the character and emerald models are from special missions, and the bosses are from boss missions.

The models are:

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 the console/PC and 3DS versions. Green Hill, along with the boss Big Arm, was playable for the 3DS version. 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.[7] 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.


Compared to the PS3/360/PC version, reception to the 3DS version of Sonic Generations was slightly less positive. GameRankings and Metacritic gave the game 69.50% and 66/100.[8][9] Official Nintendo Magazine gave the 3DS version a score of 85%, calling the game "hugely rewarding" for "high-score chasers" but did comment on the main game's short length. However, it concluded that the game was "an essential purchase for Sonic fans."[10] GamingXP gave the 3DS version 84 out of 100, stating "Sonic's debut on Nintendo's 3DS is a real success. The combination of the two different hedgehogs in the colorful 2D and 3D environments is pretty cool. The game is a little too easy, but there's tons of Sonic flair and enough content to truly satisfy the player."[11] IGN was slightly more mixed when reviewing the 3DS version, giving 7 out of 10, commenting that "Whereas the console version of Sonic Generations is a blending of old and new mentality in a fast-paced speed fest, the 3DS version is mostly just a Sonic Rush game where both playable characters happen to be Sonic." Game Informer gave the 3DS version 58 out of 100, calling the platformer's level design sloppy, making the whole product feel like a rushed tie-in with the console version". There was however praise for the game's music, 3D visuals, special stages and simple fun levels.[12]

Nintendo Power magazine editors gave Sonic Generations 3DS the "Best Retro Revival" award for the Nintendo Power 2011 Awards.[13]


  • 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.
  • This is the first Sonic game for the Nintendo 3DS.
  • This is the first Sonic game to have stereoscopic 3D capability.
  • This is the first handheld Sonic game on a Nintendo console that features fully rendered 3D stages and dynamic camera angles.
  • This is the third 3D Sonic game not to use the main theme song (or even a remix) for the final boss, the other two being Sonic Heroes and Sonic and the Black Knight.
  • Classic Tails' artwork seems to have "buckles" under his socks (above his shoes).
  • Like Sonic Unleashed (Wii/PS2), while using the Boost on a Dash Panel, Sonic performs a spin dash animation. In the 3DS version, he spins simply from touching Dash Panels regardless of initial speed and can defeat enemies during the roll.
  • This is the first time Modern Sonic gets Boost Energy from both Rings and Enemy Power in a handheld console.
  • The console/PC versions have a white colored design on top and bottom, whereas the 3DS version has a blue design. Likewise, the HD and 3DS' version's Japanese names are "White Time and Space" (console/PC) and "Blue Adventures" (3DS).
  • The rivals in this game appeared as playable characters in Sonic Rivals.
  • In the console/PC version, the drowning countdown starts at 4 instead of 5. In the 3DS version however, the countdown starts from the traditional 5.
  • The second era is the only era in which Dr. Eggman is not a boss.
  • If a ring item box is destroyed in the console/PC version, the sound when the player gets a Ring sounds ten times instead of one. In the 3DS version however, it only just sounds once.
  • Out of all seven main stages, three of the stages are based on the first levels of their respective games (Green Hill, Emerald Coast and Tropical Resort; Mushroom Hill is technically a first stage as well though not in the complete Sonic 3 & Knuckles). 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.
  • Classic Metal Sonic's artwork pose is similar to Shadow's.
  • This is the first handheld Sonic game in which the player starts a new game and are taken to the first stage, rather than showing the cutscene first.
  • In the 3DS version, Classic Tails suddenly appears after the boss battle with the Death Egg Robot/Big Arm. Takashi Iizuka said that there was going to be an explanation but it never got worked into the game's story, and he wanted to leave it open to the fan's opinion.
  • "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.[14]
  • Takashi Iizuka said that three original taglines for the game were "Blast with the past," "Déjà Blue," and "A speedy trip down memory lane."
  • While the console/PC version has a level from Sonic Heroes as part of the second era (Seaside Hill), the 3DS version has a stage from it part of the third era (Egg Emperor). In the 3DS version, Heroes' stage representation is spread throughout the eras as the game's Special Stages.
  • 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 (4 in the console/PC version, 8 in the 3DS version).
  • The third era is the one without a city level.
  • The console/PC version of the game had the highway stage of Sonic Adventure, and the first stage of Sonic Adventure 2. The 3DS version is the opposite; it has the first stage of Sonic Adventure, and the highway stage of Sonic Adventure 2.
  • Classic Sonic, in his super form, retains his black eyes (like in Sonic 2) instead of changing to the blue-green eyes from Sonic 3 & Knuckles.
  • On the console/PC version, Classic Sonic and Modern Sonic fight each rival (Classic Metal Sonic, Shadow the Hedgehog, minus Silver the Hedgehog) in the areas he fought them in the original games, but the 3DS version has Sonic fight them in areas he didn't fight them in the original.
  • The launch trailer for the 3DS version has a small mistake. During the Modern gameplay showcase, a clip from Classic Water Palace is shown.
  • The 3DS version is to date the third game to feature monitors (instead of capsules or nothing) in Modern Sonic's stages. The first game was Sonic Pocket Adventure.
  • Both City Escape and Radical Highway are the first stages for both Sonic and Shadow in Sonic Adventure 2 respectively. Both stages represented the second era.
  • In the console and PC versions, it takes about five seconds for Classic Sonic to get impatient and 35 to lay on the ground. However, in the 3DS version, it takes 30 seconds for him to get impatient and a whole minute to lay down.
  • 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.
  • In the console/PC version, Omochao works as a guide by advising the Sonics, while in the 3DS version, Tails is the one giving advice (Classic Tails to Classic Sonic and Modern Tails to Modern Sonic).
  • In the 3DS version, Classic Sonic's model becomes shinier when the player turns on the 3D effect.
  • Orcas appeared in both versions of the game, in Seaside Hill (360/PS3/PC) and Emerald Coast (3DS).
  • In the 3DS version, if Sonic gets a standard shield while having a Thunder one equipped, he will keep the Thunder shield instead of switching to the standard one.
  • All the rivals are hedgehogs or robotic copies of hedgehogs.
  • In the Unlockable Songs list, Hydrocity Zone is spelled "Hydro City Zone" instead.
  • Silver is the only rival or boss that is never faced at his original location in either version of the game. (Silver is fought in Crisis City in the console versions, and Tropical Resort in the 3DS version.)
  • Sonic Generations can be considered similar to Sonic 06, mainly since there is a creature (Sonic 06 had Solaris, while Generations had Time Eater) that devours time and the events of the game were erased in both games. Coincidentally, both are anniversary games.
  • In the 3DS version, many of the levels are direct remakes of previous acts. For example, Classic Sonic's Act of Green Hill, Casino Night and Mushroom Hill are taken straight from Act 1 of their respective games. Modern Sonic's Water Palace also resembles Act 1 of its counterpart in Sonic Rush, and Classic Sonic's Tropical Resort is a reconstruction of Act 1 of the DS Sonic Colors.
  • Time Eater being initially believed to be the main antagonist only for Eggman to reveal himself as the true main antagonist near the end is a reverse twist to most 3D Sonic games; in which Eggman is initially believed to be the villain only for another enemy to be revealed as the true enemy towards the end.
  • 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."
  • The game also shows how Sonic's skills are improving, showing his previous way of taking only slightly difficult routes (Classic Sonic), and then showing how he now goes through the truly difficult ways of the Act (Modern Sonic).
  • The Silver the Hedgehog boss battle is the only recreated/reimagined boss in the game that wasn't 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.
  • The console/PC version of Sonic Generations draws heavy inspiration from the 3DS version that it prominently has characters other than Sonic, Tails, Eggman and its in-game content is accessible via an in-game map much like the DS version of Sonic Colors.
    • Similarly, the 3DS version of Sonic Generations draws its inspiration from the Wii version of Sonic Colors in that the only characters prominent in the 3DS version is Sonic, Tails and Eggman and its in-game content is accessible by game menus much like the Wii version of Sonic Colors.
  • In the 3DS version, the main menu's music is the title screen from Sonic Mega Collection, and White Space theme is the main menu theme from Sonic Heroes.
  • "Hedgehog Jam," a music track, sounds similar to the music played during the SpongeBob SquarePants episode "Jellyfish Jam"; the music that played during the dance scenes.
  • On the 3DS version's Profile Card patterns, the screenshot used for "Sonic Unleashed" comes from the Wii version, not the console/PC version, modified to include a directional shadow.
  • This is the only Sonic game to have the Cyan Laser exclusive to a handheld game instead of appearing in both the home console and handheld.
  • 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.
    • When announcing the Cyan Laser, the announcer uses its voice clip from the Nintendo DS version of Sonic Colors, rather than the Wii version.
