Sonic the Hedgehog 4: Episode I (ソニック・ザ・ヘッジホッグ4 エピソードI Sonikku za hejjihoggu fō: episōdo wan?), originally codenamed Project Needlemouse, is the first part of an episodic video game in development as part of the Sonic the Hedgehog series. This episode was released in October 2010; it was originally to be released in the summer of 2010 but was pushed back for further development. The game was first announced on 8 September 2009,[2] and its real name was revealed on 4 February 2010.[3]

The game is a 2.5D side-scrolling platformer reminiscent of the original Sonic games, with an emphasis on speed. It is playable in high definition.[4] For Episode I, the iPod Touch/iPhone version was released on 8 October, the Wiiware version was released on 11 October 11, the PSN version was released 12 October and the XBL version was released 13 October. On 19 January 2012, Sonic 4 was released for the PC on Steam. Episode ll was released recently.

In 23 August 2011, head of Sonic Team Takashi Iizuka stated that “this year, 2011, is the anniversary, so we’re focusing on the celebration title, but moving forward to 2012, Sonic will still be going, so I’d hope to provide Episode II then.” He also said that Sonic Team “knew about the anniversary year," and that "Sonic Generations was planned way in advance," therefore "it was always our plan to release Episode II after Generations.” He however stated that they couldn't say whether there would be future episodes after Episode II.

Story

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

Sometime after Sonic the Hedgehog 3 & Knuckles, with the Death Egg finally destroyed and the Master Emerald safe, Sonic parts with Tails to explore new territories on his own. Meanwhile, a vengeful Doctor Eggman has taken measures to defeat his arch-nemesis by enhancing his past creations and mechs.[5]

Despite Dr. Eggman's best efforts, Sonic destroys each of his refined creations and chases the madman to his newest lair, the E.G.G. Station Zone. There, Sonic defeats each of his creations once again, including the powered-up Death Egg Robot, which destroys the station. Safely back on his planet, Sonic celebrates his victory in Splash Hill with his animal friends.

A post-credits scene, obtained by collecting all the Chaos Emeralds, shows Dr. Eggman laughing, along with the silhouette of Metal Sonic, leaving a cliffhanger for the next episode.

Special Stages

Special Stages in the gameplay akin to ones in the first game, where Sonic must navigate a maze to reach the Chaos Emerald, collecting rings and avoiding the exit blocks. This time, the rotation is controlled by the player instead of automatically. Controllers with motion control support can use either a traditional control method or by tilting the controller to control the rotation.

Two significant differences between these stages and the original ones are the inclusion of ring gates and a time limit. Ring gates are barriers that prevent the player from crossing into the next area of the stage, but can be passed once the appropriate number of rings, shown on the gate, have been collected. A time limit also kicks in at the start of each stage and boots the player out if they haven't collected the Emerald in the time frame. The starting amount varies by level, but can be extended in five, ten or fifteen second increments by collecting orbs around the stage.

Once a Special Stage has been completed, it can be replayed on the level select stage in either Score or Time Attack modes, with a 1-Up replacing the Emerald. Once the player obtains all seven Chaos Emeralds, Sonic can transform into Super Sonic during a regular level except for boss fights.

Electronic Entertainment Expo 2010

The game was playable by the visitors of the Electronic Entertainment Expo 2010. Players were only able to do the whole level of Splash Hill Zone. The Special Stages of the game were not shown. The game was highly praised at the E3 and there was a lot of audience at show of Sonic 4.

Development

The game was developed by Sonic Team including the original senior level designer for Sonic 3 & Knuckles[6], as well as members of Dimps. The game was released as a digital download for WiiWare, PlayStation Store, Xbox Live Arcade and iPod app store services.[7] Jun Senoue helped to compose the music of the game.

An interview with Takashi Izuka states that "Fans will be very pleased with the cast in Episode 2", implying that Sonic may not be the only playable character in future episodes. He also announced an as-yet unknown new move for Sonic, as well as announcing that the Homing Attack would appear in the game, saying: "I wanted the user to enjoy an easy-to-play feeling by the attack sequence that this [homing attack] allows, and find the fun routes in the air."

He also stated that the classic special stages will make a return and Ken Balough stated that there will be a total number of 17 stages in Episode 1, this includes Special Stages.

The game would be the same on all consoles. The Wii and PlayStation 3 version of the game will be using motion control in certain areas such as Special Stages. The iPhone version of the game will be featuring two of its own levels. Previously the console versions of the game were going to have gimmicks such as Sonic riding on a Mine Cart. But, SEGA had delayed the game and moved the date from July 2010 to late 2010; this is because they wanted to change the game to make it better and to prevent fans from knowing all of the game due to the leaks the game was getting. The Mine Cart gimmick will be moved to the iPhone version of the game, as well as some other gimmicks.

On February 8, Sonic 4 brand manager Ken Balough has gone on record to confirm that work on the next installment is underway. Sega of America and Europe also have been providing feedback and input on the subject matter. Episode 2 is revealed to have its own original Zones as Episode 1 was a throwback to Sonic The Hedgehog (1991) and Sonic the Hedgehog 2.

Leaking, Delay and Fan-Reaction

In February, a build of Episode 1 was submitted to Xbox Live Arcade's PartnerNET service, where developers were given access to upcoming downloadable titles for testing purposes. Soon after, screenshots, music and progressively more gameplay footage were leaked onto the Internet. Eventually, a playthrough of the entire game was leaked and Sonic Retro, which had already banned leaked material when more than they approved of had been released, responded by banning Sonic 4 discussion for several days. As well as this, PartnerNET shut down for a night. Other websites also made efforts to crack down on leaks, such as banning posting of leaked content. The build was controversial, due to it containing "floaty" physics speculated to be due to its using the Sonic Rush engine, poor animations and criticized the level design features such as gimmick-based acts that were disliked by most fans.

On 20 May 2010, SEGA announced that due to fan input, the game would be delayed until later in 2010, in order to extend the development of the game. They stated in game magazines and on GameSpot's On The Spot that this was specifically done to allow various fan requests (since the game was leaked) to be implemented, including more momentum-based level designs and improved physics closer to that of the Mega Drive titles.

Releases for the iPhone and iPod Touch were also announced, finally ending speculation of the fourth unknown platform, although it was leaked months before when images were found in the website's source code. It was also revealed that the iPhone version would receive two extra levels, which turned out to be the Mine Cart and Pinball gimmicks stages in Lost Labyrinth Zone Act 2 and Casino Street Zone Act 2, which were heavily criticized in the leaked gameplay footage. Sega said this was done because the levels fit the iPhone controls more. Fans speculated that the console versions would receive new, non-gimmick levels to replace them. Sega confirmed this with pictures several weeks before the final release. The new, console-specific levels were much closer in design to the other levels and featured new gimmicks which require platforming.

Criticism

Sonic the Hedgehog 4 has been criticized due to the design and content of the game. Some people believe that it is not a true sequel to the classic games, due to Episode I's content being largely based on that of previous games with minor changes, and level design that features speed boosters in every level (a staple of Dimps' level design with their previous Sonic games) and object placement that forces the use of the Homing Attack. The latter is a move that some fans do not feel belongs in a 2D game, particularly not one based on the classics and set before its debut in Sonic Adventure. The music has also been criticized, due to it featuring low-quality synths and drum samples (the latter from Sonic 2, not the more advanced ones from Sonic 3) that vary little between songs.

A highly controversial item is Sonic's design, which is the modern style model that debuted in Sonic Adventure and has since received refinements until its most recent state in Sonic Unleashed. Many fans believe that the classic Sonic design should have been used and a petition was set up for SEGA to include the different version. However, in a magazine, Takashi Iizuka said that the classic style wasn't returning, as all games since Sonic Adventure have featured Sonic in his modern design (excluding Sonic Generations for having both Sonics in the game).

Reception

The reviews of the game were mixed to positive. IGN gave the first episode a score of 8.0 and an Editor's Choice award, calling it "short but sweet and well worth downloading."[8] GamesRadar gave the PS3 version a score of 9/10, calling it "deserving of the name", Sonic the Hedgehog 4."[9]. The iPhone version had 168 reviews and all of them had given the game 4 stars out of 5. AppTilt had given the iPhone version a 9/10. GameShard gave the game a 9/10. AppAdvice also gave it a 4/5, whereas TiPb gave the iPhone version a 5/5. Nintendo Power had recommended the game for those who wanted "classic" Sonic gameplay. In aggregate reviews, the title received 81, 74, 72 and 70 via Metacritic (on the Wii, PS3, Xbox 360 and iOS, respectively) while GameRankings gave the game scores of 73.23% (PS3), 74.85% (Xbox 360) and 75.42% (Wii).

Marketing

The game was first announced through GameSpot by Sega of America on 8 September 2009, the eve of the tenth anniversary of the launch of Sega's Dreamcast video game console and the release of its launch game, Sonic Adventure in North America. At the time, it was referred to as "Project Needlemouse",[10] in reference to the name "Mr Needlemouse", which was the prototype code name of Sonic the Hedgehog when he was being pitched as a new mascot for Sega.[11]

The initial announcement was accompanied by a brief teaser trailer, which included sound effects from Sega Mega Drive-era Sonic games,[2] as well as an interview with Sega's associate brand manager, Ken Balough, who acknowledged that "old-school Sonic fans have long asked to see Sonic return to a more 2D style of gameplay", and that "Needlemouse is that critical first step that brings Sonic back to his 2D roots".[4]

Sonic the Hedgehog 4: Episode 1 Release Date: Late 2010

Conclusion of Contest

The fans "won" the bonus points contest and was awarded not only on 2 extra characters struck off the list, but a piece of concept art developed for the game (which is very similar to the same badnik in Sonic the Hedgehog 2). A local fan of the Sonic fan community also went through the raw data of the file and discovered that it was scanned to the computer late last spring[17]. The conclusion of the contest indicated that Sonic is the only playable character in this game. However, a recent issue of Gameinformer has revealed that there will be more playable characters returning for the second episode of the game.

Concept Art Challenge

On 27 January 2010, Sega updated their blog with a second (and final) challenge and another piece of concept art (Motobug, the first badnik encountered in Sonic 1). The challenge was in response to a fan-made illustration of another badnik from Sonic 2 (designed to resemble the official art), which apparently staff liked a lot. To this end, Sega stated that they wished to see more: the new challenge was for fans to submit over 100 pieces of their own art of classic badniks (from Sonic 1-3 and Knuckles, and any other game from that era) to SEGA by the following Monday, to show them which enemies they wished to feature in Project Needlemouse. Sega stated that if this number was met, on Thursday 4 February 2010 they have revealed the game's real name, concept art from the first zone, and a trailer.

Birthday Contest

In June, Sega announced a contest to celebrate Sonic's 19th anniversary where people would create videos with the winner going to Tokyo to see the finished version of Episode 1. The voting system was intended to allow one vote per day, however people found workarounds to allow multiple voting by clearing their browser's cookies and cache due to poor site coding. On 16 July, Sega suspended the voting. On 2 August, the winners were chosen by input of Sega staff and Sonic Team.

Trivia

  • The Special Stage in this game is styled after the Special Stage from the first game. Here, however, the player controls the rotation of the stage itself rather than controlling Sonic.
  • On the Sonic the Hedgehog 4 website, the Egg Mobile has longer wings. The same goes for Chopper.
  • Once Sonic gains enough speed, his running animation looks similar to his running animation in the earlier games.
  • The zones in this game are based on previous stages from the Genesis/Mega Drive series (e.g. Splash Hill Zone is based off Green Hill Zone). Episode II keeps this idea (only for Sky Fortress Zone).
  • In the Xbox 360 version of the game, you can unlock a Sonic costume along with a Sonic head for the Xbox Avatar.
  • In Splash Hill Zone Act 3, the level turns from day to sunset. This is one of few times that something like this has happened in a Sonic game.
  • In a similar fashion to Sonic the Fighters, Sonic uses a rocket ship that Tails built to get to E.G.G. Station Zone. This is not seen in mobile versions.
  • Super Sonic is playable freely like in Sonic the Hedgehog 2, Sonic 3 & Knuckles, Sonic Colors and Sonic Generations.
    • Likewise, Super Sonic can be activated by a press of a designated button.
  • The green Newtron badniks launch themselves like missiles in this game, something only the blue Newtrons did.
  • The game was intended to be released in July 2010, but it got delayed after test versions for the major consoles were slowly leaked and the fans reacted negatively to certain gameplay aspects and level gimmicks. The release date was changed to October 2010. The iOS release is, for all intents and purposes, the original version, as it retains some of the major elements. Further mobile ports are made closer to this version.
    • Casino Street Act 2 was originally a diversion in which Sonic had to acquire 100,000 points in order to reach the goal (using the slot machine is encouraged and helps acquire points faster). This level was scrapped for home consoles since testers felt that it forced the fun, so it was replaced with a longer level involving item cards, Eggman cards, and cards as flipping platforms. The music was also redone to suit the new area.
    • Likewise, the player originally had to control Sonic in a mine cart throughout Lost Labyrinth Act 2. This level was scrapped for home consoles and replaced with a much longer level in which Sonic lights his way through darkness and dynamite using a touch. although there are still mine cart sections, it is not the focus of the level.
  • This is the second Sonic game to feature a mine cart section as a gimmick, the first being Sonic Rush Adventure.
  • Interestingly, in the second trailer, in the 1992 section (Sonic 2), prototype sprites were used when Sonic is running.
  • The iOS versions has a different waiting animation - rather than Sonic getting annoying as usual, he instead starts tapping to an iPhone near his ear and even happily spins around in place.
  • In the iOS versions, Sonic's rendering looks similar to his Sonic Rush and Rush Adventure rendering.
  • At the ending, Sonic goes back to Splash Hill Zone and then jumps to the screen as in the first game. Unlike the original Sonic the Hedgehog, Sonic isn't seen using and scattering the Emeralds.
  • In this game, Super Sonic is able to breathe underwater. This is an ability taken from Hyper Sonic.
  • Special stages can be restarted from the beginning, leading to an infinite number of tries to get a Chaos Emerald as long as the timer doesn't expire or Sonic doesn't land in a goal area.
  • In this game, Super Sonic cannot be played on Boss Acts.
    • If the game is hacked so that Super Sonic is playable during boss fights, Super Sonic has his own unique victory pose, suggesting that Super Sonic was originally intended to be playable in boss fights.[citation needed]
  • This is the only game where the player can exceed the limit of 99 lives, whereas the limit in this game is 999 lives.
  • The Lost Labyrinth Zone is said to be the classic Labyrinth Zone from Sonic the Hedgehog, having been fallen into a state of disrepair.[citation needed]
  • The Wii version of the game has slightly different music than other versions. The music had to be compressed because of WiiWare's small file size limit, whereas every other version uses proper audio files.
  • This is the first and only Sonic the Hedgehog game to be released on WiiWare.
  • This game is available in all of Apple's touch screen devices except the new iPod Nano.
  • In Casino Street Zone, if you see the signs on the background of the stage, you can see Chili Dogs.
  • The title card is an homage to Sonic the Hedgehog title card.
  • The boss theme for this game was actually an unused tune for a Mega Drive Sonic 3D Blast prototype.
  • The original name for Sonic the Hedgehog 4: Episode I was Sonic DL (DL for downloadable).[citation needed]
  • The character description of Tails on the Sonic the Hedgehog 4: Episode II website states that Tails was secretly supporting Sonic from the sidelines during the game, explaining the rocket Sonic used to get to E.G.G. Station Zone in the console / PC versions.
  • The Shield does not disappear when turning Super and getting it as Super Sonic or grabbing a invincibility power up like in other Sonic games.
  • In spite of the fact Mecha Sonic is not in this series, he is mentioned in Eggman's profile in the Japanese Episode I website.
  • Since this game is set before Sonic Adventure, this is the first chronological appearance of Sonic's modern design, as well as the Homing Attack (although not its first game appearance).
  • Strangely while playing as Super Sonic, he does not earn an extra life for collecting 100 Rings.
  • In the console and PC versions, Super Sonic always wins at the slots.
  • The PS3 version of the game is compatible with the PlayStation 4's DualShock 4 controller, however, it must be connected using a MicroUSB Cable as it cannot be connected wirelessly using Bluetooth.[18]
