Sonic Generations

"DOUBLE THE SPEED, DOUBLE THE FUN! Celebrate 20 years of Sonic with Sonic Generations."

- SEGA.com

Sonic Generations (ソニック ジェネレーションズ) is an upcoming game for Xbox 360, PlayStation 3, Nintendo 3DS and PC via download. The game is being made to celebrate the 20th anniversary of the Sonic the Hedgehog series. The Japanese version has different subtitles: White Time and Space (白の時空) for the home consoles, and Blue Adventures (青の冒険) for the 3DS version. This game can be played in 3D on the 3DS and on the console versions also, but a 3DTV as well as a pair of 3D glasses are required for the PS3 and Xbox 360.

Development
Iizuka says the 3DS edition will only have Sonic friends "who are integral to the story" - a contrast from the console counterparts. The 3DS version will use some handheld game stages while the console versions will use games from the console main series. "For the PS3 and 360, none of the stages we're selecting are going to be from the handheld." Iizuka said. "However, on 3DS we're looking at picking stages from handheld as well." The 3DS will have 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, is directing the 3DS edition. Sonic Team and Dimps are co-developing the 3DS edition.

Console


The story takes some time after Sonic's last encounter with Eggman. In Green Hill in the past Classic Sonic is exploring when he hears a noise. Suddenly the Time Eater appears in the sky and he notices it as the screen goes white. In the present day Tails and his friends are having a suprise party for Sonic's birthday until a mysterious force sucks all of them back in time. Sonic goes to attack but is instead attacked himself, he looks up before he passes out to see that Tails is the only one left struggling to resist the Time Eater's vortex saying "Help us, Sonic...!!!". Sonic suddenly lands in a white world and wonders what's going on. Later on, Sonic meets his past self. After a surprising meeting, the two realize that the world is losing color and the time-line has been messed up for unknown reasons. The two Sonics team up to bring the world into its colors, learn how to fix up the timeline and save their friends.

Handheld
Like the console, the story takes some time after Sonic's last encounter with Eggman. Sonic is invited to a party by Tails. Sonic and Tails were having chilidogs until a vortex sucks Tails in, Sonic jumps in but is "attacked" but he could still get in. Sonic sees a white world and wonders what's going on. Later on, Sonic meets his past self. After a surprising meeting, the two realize that the world is losing color and the time-line has been messed up for unknown reasons. The two Sonics team up to bring the world into its colors, learn how to fix up the timeline and save Tails.

Sonic Boom
A Sonic Generations demo was playable at 2011's E3 Expo, under the name Sonic Boom. It was the first major American Sonic event, being hosted by SEGA, and took place on June 8th, at 6pm PT. At E3, Sonic Generations was playable in both console and handheld versions. Although only Green Hill was playable for the console versions, City Escape was shown; Green Hill was playable, including 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!" will appear in Sonic Generations. It appeared at the Tokyo Joypolis event and at the Summer of Sonic event in London. It appeared at the Gamescon 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 will release a demo for PSN and Xbox Live on Sonic's 20th Anniversary, June 23rd. The demo only contained Green Hill, and only the Classic Sonic playthrough. The demo was only available until July 12th, at which point it was no longer available, including for players who had already downloaded it; the file has essentially locked itself. In the Xbox Live version, one has to be an Xbox Live Gold Member to download the demo. The name of the demo is "Sonic Generations Green Hill Zone Demo #1", indicating that a Modern Sonic demo is on the way. SEGA confirmed on their blog a second demo released in Europe for PSN and Xbox Live on October 18th and will be released in North America for PSN on October 25th. The demo contains both classic and modern Sonic playable in Green Hill Zone.

Gameplay
The game features levels derived from 20 years of Sonic history, ranging from the Classic era, through the Dreamcast era, to the Modern era. There will be a level taken from each Sonic game to represent the different times. Each level can be played with either Classic Sonic or Modern Sonic, each taking their own routes throughout the level. Classic Sonic's levels are strictly two dimensional side scrolling stages, using classic moves like the Spin Attack and the Spin Dash. Modern Sonic's levels, on the other hand, carry on the modern 2D/3D gameplay of recent titles such as Sonic Unleashed and Sonic Colors, featuring Homing Attacks, Combo Tricks in the air, Drift, the Stomp Attack, Light Speed Dash, and Speed Boosts. There is going to be a new interactive menu that allows for complete immersion into Sonic's universe, as the player completes the game, extras are unlocked such as favorite characters and hidden treasures.

Hub worlds like the ones in Sonic Unleashed have been confirmed in an interview with Takashi Iizuka. He said that the hub world starts out as the white space, but opens up more as the Sonics pass through more levels. The Hub worlds will only be playable in 2D, so they are not free roam like they were in Unleashed. Also, characters rescued in that stage will stand outside the entrance to the stage, and they can be talked to. Also, there is an area above the entrance to the main stage where the payer can access extra missions and boss stages. Patrick Riley, the Director of Sega America, has talked about updated gameplay issues.

The speed boost on Green Hill inclines appears to have been fixed, among other physics issues, a few were noticed when Generations gameplay was first revealed to the world. A few issues remain, although they will be addressed. The handheld version, unlike the console versions, will make the Modern Sonic gameplay similar to Sonic Rush. Special Stages based on Sonic Heroes, along with the appearance of the Chaos Emeralds were confirmed. Casino Night is one of the 3DS exclusive stages (although it appears as a minigame on the console version), and the boss Big Arm is also confirmed as exclusive; City Escape is a console exclusive. It has also been confirmed that some bosses are played as Classic Sonic and some are played as Modern Sonic. This game like most other Sonic games will feature acts, with Act 1 played as Classic Sonic and Act 2 played as Modern Sonic, there will be several other acts for each level along with missions.

Classic Sonic
Classic Sonic stages consist of him running in a permanent 2-D perspective, platforming all the way towards an end sign post, just like in the original games. Patrick Riley referred to Classic Sonic levels as "Momentum-Based Platforming". The Spin Dash has been confirmed.

The handheld 3DS version will use stereoscopic 3-D to give a sense of depth. Classic Sonic will also have an unlockable homming attack. SEGA's Community Manager Aaron Webber revealed that Classic Sonic will be speechless.

Modern Sonic
Modern Sonic's console stages consist of running extremely fast through the stages while the perspective switches between 2-D and 3-D such as in his more recent games, Unleashed (PS3/Xbox 360, daytime levels only) and Colors (Wii only) specifically. There will also be new Combo Tricks, which are performed in the air, and fill up the Boost Gauge. It has been confirmed that there will be a new visual element to all returning levels, such as the cave in Green Hill. There will be a bit more platforming involved, like the sections after the cave in Green Hill. Also, the camera is immovable, unlike how it was in Sonic Unleashed and invisible walls can hinder the exploration aspect.

In the handheld version, Modern Sonic's gameplay will be similar to Sonic Rush and Colors (DS version) and will have Sonic Boost, the ability to slide under obstacles, jump off walls, and use the Homing Attack. Modern Sonic levels will use the 3-D effect of depth on the handheld version more actively, although the console versions will be 3D TV compatible.

Genesis/MegaDrive
It is confirmed the Genesis/Mega Drive option will be the full game of Sonic the Hedgehog, but this must be unlocked, and requirements are currently unknown.

Local/Online 2-Player Race Mode (3DS version only)
There will be a local wireless and Wi-fi 2-player race mode in the 3DS version of the game.

StreetPass (3DS only)
It has been confirmed that StreetPass will be used to unlock special content and challenges as one pass by someone else. You can also use the Nintendo 3DS playcoins system to buy said content in case that you are unable to StreetPass. With StreetPass, you will be able to trade "Profile Cards" where you describe how far you have progressed in the game, which Sonic characters are your favorites, etc. As well as adding 3 missions to exchange with other players. Once you StreetPass somebody, your profile card will get upgraded in various ways.

Voice Actors
Even though no confirmed official list has been made, Roger Craig Smith said that he's willing to voice Sonic again. His voice as Modern Sonic can be heard in demo gameplay footage. Classic Sonic will remain silent throughout the game, but will still show his personality through his actions and gestures. Cream the Rabbit and Vanilla the Rabbit’s Japanese voice actress Sayaka Aoki revealed on her blog that she has been recording some voice work for a game that will be released in the future as well (whether or not she was referring to Generations is unknown). She also mentioned Jun'ichi Kanemaru, Sonic's current Japanese voice actor.

In a joint-interview with Segabits and Sonic Stadium, Takashi Iizuka revealed there will be voiceovers for all nationalities, not just English and Japanese. Proof of this is that Sonic has received a German voice actor as heard in the Chemical Plant and City Escape video released by German game site, Gameswelt. Sonic has also received a French voice.

Spoilers
After the first demo release, released on the XBLA and PSN on June 23rd, 2011, which was the 20th anniversary of Sonic the Hedgehog's official debut, hackers from Sonic Retro mined out installed information from the demo due to the file size. A wide array of information such as levels, Hub World missions, boss battles, gameplay elements, character models, and music were extracted from the demo. These are the following:

Levels

 * Green Hill - Sonic the Hedgehog
 * Chemical Plant - Sonic the Hedgehog 2
 * Casino Night - Sonic the Hedgehog 2 (Appears as DLC in the form of a pinball mini-game)
 * Sky Sanctuary - Sonic 3 & Knuckles
 * Speed Highway - Sonic Adventure
 * City Escape - Sonic Adventure 2
 * Seaside Hill - Sonic Heroes
 * Crisis City - Sonic the Hedgehog (2006)
 * Rooftop Run - Sonic Unleashed
 * Planet Wisp - Sonic Colors

Bosses

 * Metal Sonic - Stardust Speedway from Sonic CD (Sub-Boss; Re-imagining of the race between Sonic and Metal Sonic)
 * Shadow the Hedgehog - Final Rush from Sonic Adventure 2 (Sub-Boss; Re-imagining of the final duel between Sonic and Shadow)
 * Silver the Hedgehog - Sonic the Hedgehog (2006) (Sub-Boss)
 * Death Egg Robot - Death Egg from Sonic the Hedgehog 2 (Main Boss; Re-imagining of Sonic's battle with the Death Egg Robot)
 * Perfect Chaos - Station Square from Sonic Adventure (Main Boss; Re-imagining of Sonic's clash with Perfect Chaos)
 * Egg Dragoon - Eggmanland from Sonic Unleashed (Main Boss)
 * Time Eater

Supporting Characters
Images of characters with their Japanese names written in circles (representing icons) were also extracted. The names written are the following:
 * Miles "Tails" Prower (Appears in front of the Green Hill Hub World)
 * Amy Rose (Appears in front of the Chemical Plant Hub World)
 * Knuckles the Echidna (Appears in front of the Sky Sanctuary Hub World)
 * Cream the Rabbit (Appears in front of the Speed Highway Hub World)
 * Rouge the Bat (Appears in front of the City Escape Hub World)
 * Espio the Chameleon (Appears in front of the Seaside Hill Hub World)
 * Blaze the Cat (Appears in front of the Crisis City Hub World)
 * Vector the Crocodile(Appears in front of the Rooftop Run Hub World)
 * Charmy Bee(Appears in front of the Planet Wisp Hub World)

In the list of leaked Hub World missions, it suggests that there will be co-op missions, and missions where the player will battle, race, or perhaps even play as these characters. There are also recurring missions called "Sonic Ghost", which is most likely a Time Trial mission.

Genesis
Files were found in the game regarding some sort of mode called "Genesis". Therefore there is speculation that there will be limited demos of the original, classic, 16-bit Genesis/Mega Drive games for the console versions. A Genesis can also be found on the floors of Challenges. However, it is unknown if you can play the original version of the Dreamcast and Modern eras.

Additional

 * There are two icons that depict the Spike Wisp and the Rocket Wisp, which suggests that they will be playable in the leaked level, Planet Wisp.
 * There is an icon with a set of Chaos Emeralds which confirms Super Sonic for both Sonics.
 * There are also unknown icons such as a broken stopwatch, a bolt of lightning, fire, bubbles, and one that has a ring and a Motobug. It is not known how these items will affect the gameplay. The stopwatch might freeze time, and the bolt of lightning, fire and bubbles are the shields from Sonic 3. The ring with the Motobug could also give damage, similar to the Eggman Item Box.

Trivia

 * This is the first Sonic game to have 3D capability.
 * The artworks are poses from past video games in the series.
 * This is the first game Classic Sonic and Classic Tails are rendered in a CGI artwork.
 * Jun Senoue will be mixing all the tracks for this game. The music also speeds up and slightly changes when Modern Sonic uses his boost.
 * The Classic version of City Escape is remix of the Endless Mine theme from the multiplayer mode of Sonic the Hedgehog 3.
 * Like Sonic Unleashed (Wii/PS2), when using the boost while on a Dash Panel, Sonic uses a Spin Dash.
 * The E3 Demo, Sonic Boom, is named after the opening theme in the US version of Sonic CD. Crush 40 and Cash Cash performed a remix of this song at Sonic Boom.
 * In the City Escape trailer, Fang, Bean, Bark can be seen in "wanted" posters, while Mighty and Ray can be seen on a "missing" poster.
 * Like the street signs in Empire City from Sonic Unleashed, City Escape has various buildings named after characters, such as Tails' Pizza, Coffee Blaze, Amy's Market and Vector's Daily.
 * Patrick Riley confirmed the appearance of Leaderboards for the console versions, he also revealed some unannounced form of "internet functionality" that will likely be learned about at a later date.
 * At one point in Green Hill Zone, Modern Sonic is being chased by a giant Chopper, clearly a reference to when he was chased by a whale in both Sonic Adventure and Sonic The Hedgehog (2006).
 * When doing a finish to one of his mid-air Combo Tricks after going through a rainbow-colored hoop or a special dash panel ramp, Modern Sonic does the same widely recognizable pose as he does on the cover for Sonic Adventure.
 * The first 2 gameplay trailer featured an instrumental version of a famous song:
 * Tenderoni by Kele Okereke (Green Hill).
 * Na Na Na by My Chemical Romance (City Escape).
 * Takashi Iizuka revealed that the reason Sonic Generations is coming to the 3DS is because the Wii isn't a good fit for the game, since the primary goal for the console versions is to reimagine classic stages in vivid, HD graphics. So they decided that, for the Nintendo audience, it would come to the 3DS.
 * This is the first time Modern Sonic gets Boost Energy from both Rings and Enemy Power in a handheld console.
 * This is the first time that Classic Sonic gets a rank on his stages.
 * In this game, Classic Sonic has different waiting animations. One looks similar to Sonic 2, one looks similar to Sonic 3 and one looks similar to Sonic 3D Blast.
 * During a Spanish interview with Diana Redetski, a spokesperson form SEGA Spain, she revealed there might be a way to do a Modern Sonic/Classic Sonic switch, as a toggle feature
 * In addition, in the list of leaked missions, it seems there are levels played right before the HUB worlds, in every stage, where the player plays as "Both".
 * Red Rings will be in the game, but they have been renamed as "Red Star Rings."
 * This game has been in development since Sonic Unleashed was released.
 * If noticed, the PS3/XBOX 360 versions have a white colored design on top and bottom, where as the 3DS version has a replacement for blue, this is reference to the consoles and handheld's version's Japanese name, White Time and Space (PS3, XBOX) and Blue Adventures (3DS).
 * Some of the stages in demos of the 3DS version have been presented with placeholder music. For example, the Big Arm boss fight used Doomsday Zone's music in the E3 2011 demo, but was changed to the final boss theme of Sonic 3 in the Gamescom 2011's demo.
 * Takashi Iizuka recently said via Twitter that, after seeing Sonic CD on Xbox Live, he is upset that they missed their chance for Wacky Workbench in this game, with "bouncy floors and boosting".
 * This is the first main series Sonic game on the PS3 to have hidden trophies.
 * In this game, Sonic and Tails are the only characters to have both a Classic and Modern form confirmed so far(Unless you count the cameo of Robotnik while he's controlling Big Arm in the 3DS version and on the signpost in the console version).
 * The rivals 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 bosses.
 * In this game, the countdown to drowning starts at 4 instead of 5.
 * On the case cover of the Xbox 360/PS3 version, Modern Sonic's run looks similar to the one on the case cover of Sonic the Hedgehog (2006) which was also released on the 360 and PS3 consoles. On the 3DS one, Modern Sonic looks similar to the one on the case of Sonic Classic Collection, which was released on the DS.
 * It has been hinted that enemies from the Sonic '06 game will appear in Sonic Generations. However, the end of Sonic '06 erased the events of the game, which should have erased the enemies from the timeline entirely.
 * The Dreamcast Era is the only era in which Dr. Eggman is not a boss.
 * In the E3 demo of Green Hill Act 2 (when the game was in early development), at the beginning of the stage, Sonic said "Ready...Go!", while in the last Demo, he doesn't.
 * When Classic Sonic runs, a blur effect is set in the background.
 * If a 10 Rings box is destroyed, the sound when you got a Ring sounds ten times instead of one.
