Prerelease:Sonic the Hedgehog (2006)

This page details prerelease information and/or media for Sonic the Hedgehog (2006).

Sonic the Hedgehog was planned to be a "rebirth" of the franchise, where the team wanted to implement many features that were not featured in previous games. However, Yuki Naka's resignation in early 2006 and producer change had unexpectedly lead this game to be released at the end of year, resulting in a lot of rushed development and poorly-implemented ideas in the final product.

It was critically panned by fans and critics alike upon release.

Early Ideas

Realistic Textures/Models

• 
• 
• 
• 
• 
• 
• 

Early in development, Sonic Team experimented with using realistic fur and rubber textures on the character models, since the game world was more realistic. The textures are not in any known build of the game, but these renders by Blur Studio show what they would have looked like.

Day and Night Cycle

• 
• 
• 

A day and night feature was shown in the TGS demo fully implemented and functional, but it's unclear if it was ever intended to be in the final game and may have just been a demonstration of what the next-gen technology was capable of. The next mainline Sonic game Sonic Unleashed does feature a day-night cycle, but only after completing stages.

Features Mentioned in the Manual

The game manual was probably written before the game was finalized, because it mentions features that were never implemented... oops. Note that this list omits features that are still present in the game's code, like the shield.

• The game's manual states under Tails and Omega's character bios that you can use their flight abilities until the gauge runs out. However, in the retail game, no such gauge is visible onscreen.
• Sonic's Gem abilities are described as being able to upgrade up to Level 3, draining energy when used, and that Chaos Drives power up the bar like for characters which have a working one, but this function was never finalized. Despite this, the bar still shows up when you play as Sonic anyway.
• The hub worlds and action stages are referred to as having a level indicator. This is meant to show the current level of Sonic's custom actions and Shadow's Chaos Boost, but since Sonic cannot level up his Gem abilities in the retail release that behavior goes unused. It's still used for Shadow.
• When discussing the game's "Tag" multiplayer mode, the manual mentions significant differences compared to what's seen in the retail release. It says there are two variants of Tag: Tag Story and Tag Trial. Tag Story seems to have been much like what Tag is like in the retail release, but players could save their progress. Completed stages could then be chosen to be played individually in Tag Trial. In the final release, it's much more barebones: you can't save progress in Tag, and individual stages can't be played at will.

Canceled Ports

Sonic the Hedgehog was only released on the Xbox 360 and PlayStation 3, but versions for Windows and the Wii were also planned. Nothing is known of the Windows version other than being promoted on the back cover of the Sonic Riders instruction manual (which mentions it was due for release on PC DVD-ROM alongside the Xbox 360) and the game's E3 2006 flyer. The Wii version was scrapped in favor of Sonic and the Secret Rings; a full port would've been possible, but would have taken too long, and Sega wanted a Sonic game to release in time for the Wii's launch.

Demonstration

The E3 2005 demonstration that represented the announcement of the project. It was shown behind closed doors, meaning not many people would get the chance to see it. Of course, the internet is a wonderful thing, so it ended up finding its way online.

The demonstration is around two minutes long and shows Sonic running around what appears to be an early version of Kingdom Valley while fighting Eggman's robots. At the end, he transforms into Super Sonic and rams into a giant robot fleet.

September

TGS 2005 Closed Doors Tech Demo

Gameplay was first shown off at TGS 2005 in a prototype version of Kingdom Valley, with a number of differences:

• Sonic's character model is different, looking a little more detailed and like the prerendered CG cutscenes. Sonic's shoes are also shiny and have the area reflecting on it. The final game features a much brighter, less detailed Sonic.
• Sonic's animations are different and closer to his depiction in Sonic Adventure. They also seem a little unfinished, as he uses a walking animation when jumping on a rope, similar to Shadow in the final game's stage "End of the World". Strangely, this glitch doesn't happen later on in the footage. These animations actually still exist in the final game, they're just unused.
• The game is running slower, presumably because of how early in development it is. Despite the slow speed, Sonic goes extremely fast when grinding.
• Many debug functions are seen, including freecam and levitation.
• The day-night cycle is seen functioning via debug controls. It's unknown how the cycle worked, but it is shown that it fully moves along with the shading.
• The assets are a little different from the final. For instance, the boxes don't have stars on them, making them more realistic. In contrast, the springs and dash panels don't look as realistic and look closer to their depiction in Sonic Heroes.
• Sonic seems to be directly homing into the ground, which does not happen in the final game as Sonic air dashes instead.
• The level ends earlier, presumably because it wasn't finished yet. Notably, the level-clear jingle is the same version from Adventure, Adventure 2, and Heroes.

Leaked Script

To do: Upload the original, unmodified file (not one downloaded from the Google doc).

Before the game was released, a UK tester obtained an early script and leaked it to the Sonic fansite Sonic Cult. The document, "SONICNEXT_allscript", is an internal document saved in XSL format. It contains some pretty interesting insight into the game's development, including unused concept art. The leaked script can be read online here.

• For the character bios, Sonic, Tails, Knuckles, Shadow, Omega, and Amy all use their renders from Sonic Heroes, while Blaze uses line art from Sonic Rush. Elise, Eggman, and Mephiles use their renders from the final game. Silver, the Duke of Soleanna, Soleanna's scientists, and Elise's maids use concept art that was never seen during the build-up to release. Rouge, the G.U.N. soldier, and Iblis do not have any images.
• Silver's original name was Venice (a name that is still used internally in the final release), and was based on Trunks from Dragon Ball Z. He was also supposed to have an ability that drew from the powers of the Chaos Emeralds. According to the script, he was renamed Silver on November 22, 2005.
• Princess Elise was originally named Princess Oliga (named after Russian singer Origa). Her name was changed on March 5, 2006 (after voice recording had begun).
• The hub world was going to have desert, snow, and forest areas. In the final, only a forest area made it in. This is why the script asks the player to "Go to the desert!" early in the game.
• A lot of the prerendered sequences (e.g. Sonic and Elise in the forest) were going to be in-game sequences.
• Some bosses are referred to as "Amigo Bosses", which indicates you would've had to fight them as secondary characters. For instance, the script (including the final version) implies that Tails was supposed to be the one who fights Egg Cerberus, which is listed as an Amigo Boss.
• The name of the Scepter of Darkness changed a few times. It was first the way edgier "Tears of the Sun", before becoming the more generic "Book of Darkness", and then finally the Scepter of Darkness. It's worth noting that there is one scene where it is accidentally referred to as the Book of Darkness.
• For some reason, between Silver's final boss and closing cutscene, he's given the town mission "Get info on Mephiles". This is only seen in the leaked script, which is understandable because it makes absolutely zero sense.

The last revision to the script was made on March 10, 2006. At this point, it was essentially the same as it is in the final; the only differences are minor sentence restructures.

E3 2006

Trailer and Demo

A demo and trailer was shown at E3 2006. The version shown has a huge variety of differences from the final.

• The main menu for the demo has two stages that can be selected: Kingdom Valley for Sonic, and Crisis City for Silver. It features unreleased character art.
• The first section of Kingdom Valley is played. After Sonic grabs the eagle, the speed section is used. Silver's Crisis City ends near the end of the first section, where the second PK Mark before the last checkpoint is located in the final game.
• The character voice acting doesn't play.
• The loading screen is different. It's a blue screen with the level's name with an objective at the bottom, rather than an image of the level with control tutorials. The Now Loading text also fades away instead of completely disappearing.
• The HUD is different, featuring a Sonic head for the character image, which was also used in Sonic Unleashed. Sonic's power meter also isn't on-screen, but Silver's is.
• When an Item Box is destroyed, its icon does not appear at the bottom of the screen. Additionally, the 1-up Item Box is completely different, and breaking it plays the 1-up jingle from Sonic Adventure rather than the one used in the final.
• Sonic and Silver have all the moves unlocked.
• Sonic and Silver run faster in the demo. In Sonic's case, he actually gains speed by collecting rings, something that's not present in the final. It's more noticeable when Sonic uses his slide kick.
• Sonic's homing attack works differently. When using the homing attack, Sonic falls to the floor instead of air dashing, which would help landing on platforms more. It's also spammable without a delay. He also has multiple different animations for flips and stuff, which are used in the final game with the White Gem.
• When Sonic is jumping from wall to wall, he curls up into a ball before landing, which doesn't happen in the final game.
• Silver can fly while carrying objects unlike the final.
• Kingdom Valley has a big blue sky rather than an overcast in the final game, making the lighting more noticeably different.
• Sonic seems to float around after missing the Light Dash trail in Kingdom Valley, possibly to make it easier for the players playing the demo.
• The subtitle font is bigger.
• When the Goal Ring is touched, the game doesn't freeze to load data, and has a Mission Completed text.
• The trailer has Sonic running in Tropical Jungle without carrying Elise.
• In the trailer, the town seems more lively with more people interacting with each other.

Early Music

Both stages' background tracks in the E3 demo haven't been finished. As such, they have different, synth-y instrumentation. In particular, Kingdom Valley is missing a choir section in "The Castle" track, while Crisis City doesn't include "Tornado" and loops at the end of "Whirlwind".

  Retail

In the game's manual for both the Xbox 360 and PlayStation 3 release, there are many screenshots showcasing pre-release versions of the game. On Page 7 under the Town Stage section, there is a screenshot showcasing Soleanna Castle Town. Highlighted as "money" is an early icon for the total rings counter, shown above. It features a ring (most likely taken from the in-game HUD) with the letter R in the New Rodin font.

In the footage for the E3 version of the game, this early 1-UP icon can be spotted in this item box. It depicts two yellow arrows above the same "UP" text used on the retail 1-UP icon.

Early Opening Cutscene

Has different camera angles and music. Most notably, Elise is voiced by Veronica Taylor instead of Lacey Chabert.
