This article pertains to the beta elements from Sonic the Hedgehog (2006).
Originally, every character was going to have their own episodes, but the idea was scrapped from the final version. Metal Sonic was going to be an extra playable character as well, but was scrapped as well.
Silver the Hedgehog
Silver had a more than one background concept done by Sonic Team. One was leaked from the Sonic Team in a "XLS" containing biographies of all the playable characters, along with scripts. Here, Silver is described as having special power that can draw upon the Chaos Emeralds. The concept of his creation was based on Trunks from Dragon Ball Z according to the same profile. However, the profile of Silver was described as "Temporary", explaining why it was not used, while all the other profiles were were later used in the official guide and on the game's websites.
In-game model animations
By swapping the character files of some of the Amigo mode characters with those of the regular characters, it is possible to view animations of some of the supporting characters that do not appear on the character selection screen.
Knuckles's unused pose and quotes
In regular gameplay, Knuckles is the only character that cannot complete an Action Stage on his own. As a result, his finishing pose and quotes are unused. However, it is possible to complete Flame Core and Aquatic Base with Knuckles by avoiding the character-switch sections, thus recovering his following quotes at the goal:
- S ranking - "All right!"
- A ranking - "That felt good"
- B ranking - "Well that wasn't TOO bad"
- C ranking - "Shoot! I've still got a way to go..."
Night and Day
A day and night feature was originally planned for the game, but was cut due to time constraints. This feature was shown during the demo for the game, and is evident during the cutscenes where Sonic travels through Soleanna at night.
There was originally going to be a mode named "Super Hard" for Sonic, Shadow and Silver which was extra difficult missions for each character. It is unknown if it is the same as the game's Very Hard mode for its DLC contents or not.
Chaos Smash was supposed to be a less advanced version of the Chaos Snap. It is only mentioned by the Shop assistant who says that the Chaos Snap is a more advanced version of the former. However, it cannot be used in gameplay.
Blaze's Pyrokinesis moves
It was planned to be combos between Silver and Blaze. By pressing /, the player could use Blaze's pyrokinesis to wrap her in flames. There was also another combo where Silver could pick up Blaze and throw her to launch a powerful attack. These are all intended for both the first and third fight against Iblis.
There are a number of unused lines in the game indicating there was a number of different missions that did not make the cut, as neither Chao, ghosts, or mode selections appear in the final game:
- "Get to the goal within minutes!"
- "Collect rings!"
- "Defeat all enemies!"
- "Wipe out all enemies!"
- "Get to the goal within minutes!"
- "Collect rings!"
- "Get to the goal before your rival!"
- "Get to the goal before the ghost!"
- "Find Chao!"
- "Find the Goal Ring!"
- "Get to the new Goal Ring!"
- "Clear the minigame!"
- "Clear hard mode!"
- Sonic the Hedgehog 2
- Sonic the Hedgehog 3
- Sonic 3D Blast
- Sonic & Knuckles
- Sonic Adventure
- Sonic Adventure 2
- Sonic Heroes
- Sonic R
- Sonic Riders
- Shadow the Hedgehog
Crisis City varies greatly between its prototype pictures and its finalized version. The Action Stage originally held Eggman's mechs (similar to that of the DLC version) instead of Iblis's minions and included sections that was cut from the final version. There were also Springs which Sonic used to bounce between walls instead of using the Wall Jump mechanic. Also the prominent tornado is still included, but is made of dust instead of flames.
While not to the same degree as Crisis City, Tropical Jungle is quite different from its finalized version. Here, Sonic's eyes are darker and some unknown sections were included. The Vine gimmick is also used to travel to an unknown area, whereas in the final version, they are just used to swing upward. Most noticeably however, is that Sonic does not carry Elise during his gameplay (like in the Very Hard mode for the DLC content).
Kingdom Valley is quite different from the final version. There are multiple unknown areas that appeared in the prototype images which were not seen in the final version, some with different placements of the enemies and more Ring trails for the Light Speed Dash. In some of the very early screenshots, the Springs have a different model which resemble the one for Sonic Heroes.
Early Town Stages
- Vehicles that drive through the city. However, their AI is unfinished as they often drive into buildings.
- Mirrors of Soleanna for Crisis City and Flame Core. However, they can not be entered.
- An unused pigeon NPC called "Hatsun" that the player can speak to. This brooding little creature only say "Coo..."
Unused Town Mission/ Defeat all the enemies and protect company employees!
There is an unused mission in the New City that takes place at the same time Shadow is going to the Dusty Desert. Once the player proceed to where the unused Mirrors of Soleanna are, the mission will begin. In this mission, the player has to protect the employees and watch over their health measure. To succeeding in this mission, the player must destroy the leader of every group consisting of the purple Iblis Minions, thereby destroying them all. Some enemies are not linked though, and must be destroyed individually. The mission is filled with Super Rings and Chaos Drives power-up items. At the end, the player must destroy four Titans. After finishing it, the employee Mazzola will say what is happening and what they are working on at the Rimlight company. At the end, he will say that there is a Light Core reaction in the Dusty Desert. Note that this mission will not be saved in the save data once completed and every time the player reenters the unused City, it can be played again.
- Double sets of doors in several locations, including the entrance to the Forest that can only be seen by clipping through the walls.
- The Forest itself holds a multitude of signs, including signs with the "no" symbol, checkered strips, stop signs, and speed limit designations. The latter two can be destroyed with the Homing Attack. On top of that, they are unused remnant of the cars planned for New City.
- No NPCs are included in the Forest.
- The bridge to the gates are not present.
By utilizing a glitch, it is possible to reach an early development version of Castle Town right after returning to the present from Flame Core in Shadow's episode. This version is without its doors (just a black room) that lead to the Forest and New City. The player cannot speak to people and there are two bridges near the supposed entrance to the Forest. One leads the player to between both sides of the town and the other one leads into a wall. When entering this area, the player will be stuck and can only get out by exiting and reentering the episode. Should the players save their progress in this area however, they will be stuck there indefinitely with no escape.
Super Gem/Rainbow Gem
The Super Gem is a Level Up Item that was in the Demo/final version of the game, but was not finished and scrapped. This Gem was presumably meant to let Sonic the Hedgehog transform into Super Sonic in normal gameplay. By hacking through the game's files, the player can make use of it, but it will only make Sonic use a "Transformation pose" with no special capabilities.
Aside from the "Radical" and "Good" bonuses that appear when a pack of enemies are defeated, there are a lot of bonuses in various languages in the game files that were not used in the final game. It should be noted that they bear an resemblance to the score rankings that appear under similar circumstances in Sonic Adventure 2 and Sonic Adventure 2: Battle.
Unused Mirrors of Soleanna
Every Action Stage except Crisis City, Flame Core and the End of the World have their own Mirror of Soleanna. However, there is a texture in the game-files that shows an image for the Mirrors for every gate, including the three absent stages. Some of these normally unused Mirrors were later found by forcing the game to load unused object layouts into some of the hub areas with the use of glitches and gameplay tricks, but due to fact that they were not programmed to behave like the Mirrors the player normally interacts with, they are not working.
The game files hold a variation of "His World" without lyrics (the one used in the game's commercial). Parts of this song can be heard at various points in the game, such as in the main settings, multiplayer, and Solaris phase 2, but none of them have the complete track.
Dreams of Absolution
The Shield was presumably a power-up that was meant to appear in the game and was even listed in the game's finalized manual. If the player uses a special mod to swap E-123 Omega with Silver the Hedgehog in Crisis City and grab an Item Box, the Shield's icon will appear on the bottom of the screen, although it will not change the contents of the Item Box.
Unused lines and mechanics
In many of Sonic and Shadow's unused lines, several plot points can be heard which was removed from the game. These include absent parts of the stories and scenarios, like where both Sonic and Shadow worked together to find all the Chaos Emeralds before Eggman in a scrapped final stage. Unused animations in the game data also suggest that Sonic was going to use the Buggy and have an alternate falling animation. These differences also apply to some of the supporting characters, especially Amy Rose.
There are also lines that hints of moves absent from the game, multiplayer quotes for every character (even Elise), Shadow vs. Rouge Town Missions, and Eggman talking about many subjects, like the Eye of Solaris and some hidden stories.

Mephiles: Hmm, it seems I underestimated you!
|Blaze: It looks like the center core is protected by a barrier! Let's start by destroying the things around it!
Blaze: The barrier is down take out the center control core!
Princess Elise: Sonic!
Princess Elise: Watch out!
Dr. Eggman: Ehhhh! My aerial fortress! Reinforcements! Where are my reinforcements!?
|Egg-Genesis. The core is not protected by a barrier, but by the mech's wings, although the core can be damaged whether the wings are intact or not.|
|Princess Elise: Noooo!
Sonic: Those robots are coming from the cockpit! If I use them, I can reach Eggman.
|Egg-Wyvern. Although Eggman uses laser cannons to attack Sonic, they are not robots.|
|Sonic: If I just attack from the front, I'll get caught by that strange power! I've got to find an opening!
Silver: Normal attacks won't work while he is in mid-air! I've got to find an opening somewhere else!
Sonic: I can't let that strange power hit me! I've got to use Homing Attacks on the things he throws to close in on him!
Silver: His movements are just too fast! But If I can figure out the direction he is planning to charge in, I can block it with my Psychokinesis!
Sonic: The attacks from the ground are a pain to avoid! But If I can evade in mid-air, I might find an opening to attack!
Silver: When he staggers, that's my chance! If I can get close, I should be able to to grab him with my power!
Sonic: YOU!.... Who are you?
Silver: I can't.... lose to you!
Sonic: All right! I don't know who you are, but you're no match for me!
Silver: Iblis trigger? Is that all you've got?
|The battle against Sonic, and vice versa.|
|Shadow: Attacking from the front, leaves me vulnerable to that strange power! I need to find an opening!
Silver: Those arrows of light! I need to watch out for them! They seem to stop my movement!
Shadow: That strange power! I might be able to stop it with my Chaos Spear!
Silver: Right before he shoots the arrows of light, he leaves himself vulnerable in mid-air! If I can attack him then!
Shadow: If I can hit him with the Chaos Spear when he lifts up a train, I should be able to create an opening!
Shadow: Witness the might of my Power!
Shadow: Now you're asking for it!
Silver: Why? Why are you getting in my way?
Shadow: Oooh! My body!
Shadow: I can't believe it!.. How can it be?
Silver:aaah! I can't lose here!
Shadow: You're still too inexperienced!
Silver: Sorry, but I can't afford to stop here!
|The battle against Shadow, and vice versa. In the battle against Silver, he does not lift a train.|
|Amy: Silver! Your power can become a Shield of Light! If you trap your power into the green light, you can attack him directly!
Dr. Eggman: That's a dimensional hole! Can he summon things from other dimensions into this warp space?
Knuckles: No problem, Sonic! Just blow them away before they come out!
E-123 Omega: If you use your Spear of Light, you should be able to destroy the material, and close the dimensional hole!
Dr. Eggman: Nooo! Now, he is trying to suck you into another dimension! If you don't want to take on unplanned trip, Evade..Evade!
Knuckles: If you evade up or down, you can attack him directly!
Knuckles: When he spreads out both hands, he will attack from the right and the left!
Miles Tails Prower: Solaris's light shells match up with up, down, left and right, with the left stick/left analog stick. Use it to do damage!
Miles Tails Prower: Noooo!
|Solaris fight. The Shield of Light cannot attack Solaris directly without catching projectiles first. Also, the Spear of Light cannot destroy the eyes of Solaris.|
|Sonic: It looks like I can jump from there!
Shadow: Watch out! It is gonna blow up!
Sonic: This lamp post... Maybe I can swing off of it!
Shadow: Naaaah! Can I get out?
Shadow: So much debris!
Silver: Blaze! Watch out for things flying out of the tornado!
Sonic: Here comes a billboard!
Silver: This steel bar has a green mark on it, If I use my Psychokinesis here!
Silver: That road does not look too solid!
Silver: I can wipe them out, If I hit that pipe, right?
Blaze: Use your Psychokinesis! You should have no problem with the enemies' bullets.
Blaze: It looks like you can take advantage of this concrete ramp!
Shadow: Haah! You're talking to me?
Sonic: Shadow! Don't be late!
Shadow:Haaa! Will I make it?
Shadow: Sonic! Let's hurry!
Sonic:Okay, let's blast through here!
Sonic: Hang on, Shadow!
Blaze: We need to go across the buildings!
Sonic: It is gonna blow!
Shadow: It looks like Sonic was swept up into the tornado! If I use my Glider!
Sonic: Shadow was swept up into the Tornado!!! I've gotta help him!
Shadow: There is no need to stay long!
Sonic: This is terrible!
Sonic: If we take too long, It will collapse!
Shadow: You wanna test me, do you?
Silver: If this keeps up!?
|Crisis City. In gameplay, the player cannot swing off a lamp post, nor does Shadow works with Sonic. In addition, Sonic and Shadow do not suck in the tornado in the level in anyhow.|
|Princess Elise: Don't get caught up in this sand wave!
Shadow: I have to be careful not to get caught up in this sand wave!
Shadow: I guess they are not gonna welcome me into the ruins!
Shadow: It looks like these pillars will lead me to him!
Amy: This ball counts down each time you touch it! Be careful carrying it!
Princess Elise: This ball counts down every time you touch it!
Silver: So I guess the lock will open if I put this ball in that hall over there!
Silver: I might be able to make a path leading up, if I use my power over there!
Shadow: It looks like this big statue is getting pretty fragile!
Princess Elise: When I am with Sonic, I feel stronger somehow!
Shadow: I'll take him down, no matter what he does!
Shadow: I'll defeat Mephiles, no matter what!
Shadow: I am starting to feel his presence, let's go!
Princess Elise: This design, it looks like it is from Soleanna!
Shadow: Mephiles! Just you wait!
Amy: I'll find you Sonic! No matter what!
E-123 Omega: Mephiles detected!
Rouge: Whatever happens, I'll believe!
|Dusty Desert. In Sonic's version, there is no Spheres. Also, Rouge has no lines in Shadow's version.|
Knuckles: Shoot! This can't be happening!
Rouge: This isn't good, we need to hurry!
Shadow: The Chaos Emeralds! Where are they?
Silver: There is no more time, let's hurry!
Miles Tails Prower: The Chaos Emeralds! Where are they?
Amy: Oh nooo! I am getting sucked in!!
Knuckles: Be careful not to get sucked into the rift!
E-123 Omega: High energy reading detected! Evading!
Rouge: If you get sucked into the rift, it is over!
Shadow: I need to stay away from that!
Silver: Hah, it is over if I get sucked into that!
Miles Tails Prower: Be careful! Make sure you don't get sucked in into the time-space rift!
Amy: Oh no! That weird rift is growing!
Knuckles: The time space-rift? Is it growing?
E-123 Omega: High energy reading increasing!
Rouge: What!? The rift, it is growing!
Shadow: That rift, is it expanding?
Silver: The time space-rift is expanding! We must hurry, or time will disappear!
Miles Tails Prower: The time space-rift is really expanding!
Amy: The rift is gone! We've got to hurry now!
Knuckles: Oh, right! Now, let's look for the Chaos Emeralds!
E-123 Omega: High energy reading decreasing!
Rouge: The time space-rift disappeared! We've got to collect the emeralds now!
Shadow: All right! Let's hurry!
Silver: The rift disappeared! Now, I have to hurry!
Miles Tails Prower: The rift is disappearing! All right, let's look for the Chaos Emeralds!
|End of the World. Although the time-space rifts do not grow in size, they still expand in numbers. Also, only the red ones disappear automatically.|
|Shadow: Heh, you can't stop me!
Sonic: Whow! Are you coming up to say hi?
Shadow: I've gotta hurry, the bridge won't hold!
Sonic: This bridge is gonna collapse any minute!
Shadow: I guess this flame dies after a while!
Sonic: Wow! The flame died!
Silver: Dang! Out of time!
Shadow: Gotta watch out for the fiery areas!
Shadow: Hmm, that took a couple of time!
Blaze: Iblis! This time I'll finish you!
Shadow: Is this really what our future holds?
Knuckles: This terrain is so tough!
Rouge: This kind of places is no sweat for Rouge the Bat!
Shadow: The Chaos Emerald should be...
|Unused lines in Flame Core. In the game, Blaze has no lines in this Action Stage, as she is not seen with Silver there.|
|Silver: That tower has a big crack in it.
Silver: Man, the staircase is damaged. Now I have to use my power!
Silver: Wah! This building is crumbling!
Rouge: You can use this vehicle to get across the lake!
Silver: I can manage this cage with my power!
Rouge: If you cut this chain, it will take them right out.
Shadow: The wind is strong in this valley!
Silver: Sonic, we don't have time! Let's get to Elise right away!
Sonic: Silver, it is all yours!
Rouge: I wonder why Soleanna moved the castle away from here!
Shadow: How is this work?
Sonic: Nooo! We can't be stuck here!
Sonic: Riding the wind brings back fun memories!
Rouge: This is Kingdom Valley. Long ago there was a royal castle here.
Sonic: The crest of Soleanna in an Eagle! I see.
Rouge: I wonder if we can find the treasure of Soleanna?
Shadow: That case...?
Silver: Aaaah! What a mistake I made?
|Unused lines from Kingdom Valley.|
|Sonic: All right, Tails! Let's race to the bell!
Miles Tails Prower: Okay, Sonic. I won't lose!
Sonic: Nice try, Tails!
Miles Tails Prower: Yaay!
Sonic: You're the one who did it!
Sonic: Not gonna give up are ya? All right, I'll take you all on!
Knuckles: All right, I'll help ya!
Sonic: Ok then. Tails, Knuckles, let's do this together!
Miles Tails Prower: Team Sonic is back!
Knuckles: It is all you Sonic!
Miles Tails Prower: Here you go, Knuckles!
Amy: Ughhh! What are you doing Silver!?
Silver: Where is Amy going?... I might be able to learn about Sonic if.... I'll try following her!
Amy: Sonic! I hope I can give this to him, the next him I met him.
Blaze: Eh...! There's too many enemies!
Silver: Blaze! I am coming!
Blaze: Silver! Thank you!
Rouge: Hey Shadow! How about a little contest to see which one of us is the better special agent!
Rouge: Ah, come on! Let's go!
E-123 Omega: Detecting multiple readings on radar!
Shadow: The doctor is not holding back, is he? Let him witness my ultimate power!
|Several unknown missions.|
|Silver: I'll blow away these containers with my power!
Shadow: I can jump over the area without any cargo.
Sonic: That's only the place without any cargo.
Shadow: You think that those attacks are gonna keep me away!
Shadow: I am get to have to use homing missiles so he does not get away!
Princess Elise: Hah... ooowah.. Help Sonic! Help!
Unknown human: Ugh, my head! Oh ah! Help us Sonic! Oh heavens, help us!
Sonic: Eggman! haaah! I better go help! Gotta hurry!
Hint Ring: Just touching that switch won't do anything! You need to apply force and move the lever.
Shadow: If we don't hurry, Dr. Eggman will escape!
Silver: I've got to catch up with Sonic!
Shadow: I am going after the doctor!
|Several unused lines in Radical Train. There are several humans voices for Sonic's version of the Action Stage that did not made it into the game, depicting passengers' panic. Also, one file contains two voices belonging to an old woman and old man.|

|Princess Elise: You might be able to knock down that fruit!
Rouge: That fruit looks suspicious!
Sonic: Something might happen If I knock down that fruit!
Princess Elise: How about riding this Turtle?
Rouge: It looks like you can get around this turtle!
Silver: This hanging ruin might be usable!
Silver: If I can hit that ball with this!?
Sonic: It looks like I can grab that vine with the fruit with a Homing Attack.
Silver: Is this for breaking walls?
Rouge: It looks like you break this platform.
Rouge: This Lotus will throw you high in the air!
Sonic: This Lotus can be used as a trampoline!
Rouge: Don't wanna fall in this water!
Rouge: It is a pretty smooth ride!
Silver: These are submerged ancient ruins!
Silver: This turtle is pretty useful, Once you get it right!
Sonic: Oh! Is there a back road?
Princess Elise: Hah! My heart is racing!
Princess Elise: If you jump when the bud is glowing, you may be able to jump higher!
Silver: Where did Blaze go?
|Unused lines in Tropical Jungle.|
|Miles Tails Prower: I think you can stop the searchlights if you hit them with bombs!
Rouge: Hmmm, one... Two...Three... There are five searchlights!
Rouge: You know when you get caught in searchlights, you've got to have to use bombs!
Miles Tails Prower: Press and hold the A/X as long as you can, and release it right at the Jump Ramp!
Silver: If I use it right, this snowball can be a weapon.
Sonic: Now, that's a big snowball!
Blaze: Hhh.. Security is tight! You don't wanna to be discovered. Be careful!
Sonic: Dang! There is no time! Let's keep going!
Silver: Ok! A little farther to go into the base!
Rouge: Yeah! Now we can get out of the base!
Rouge: We gotta out of the base, but the security is really high! Let's see...

Rouge: I was only a little slow getting out!
Rouge: I got in successfully! I got the treasure too!
Rouge: This treasure! ha..aaah!
Shadow: We need to get out of it quickly!
Sonic: Eggman sure built himself a huge base!
Silver: The truth....
Miles Tails Prower: Mhhha! It is freezing!

Miles Tails Prower: Thanks for waiting Sonic!
Shadow: What about Omega?

Eggman without Sunglasses
In the game files, there is a yet-completed picture of Eggman without his glasses before he makes Team Sonic travel to the future.
Soleanna and Egg Carrier's maps
In the game files, there are a lot of pictures that are presumably used by Eggman on the Egg Carrier to locate the Chaos Emeralds. The maps included the errors that occurred onboard the Egg Carrier before it crashed.
The pictures also include renders of the Soleanna newspapers that Sonic read upon his return to the present from Flame Core.
Leftover E3 Content
Two loading screens from the E3 demo of the game were left within its data. Note that both of them state "Head for a Goal Ring!"
Several graphics related to the multiplayer mode of the game still exist in its data, but was not used.
Jump Board model
In one of the game's files, specifically the one called "jumpboard", there is an unused Ramp model that is identical to the one used in Sonic Unleashed and onward. It was most likely left out because the game uses the Ramp model for Sonic Heroes and the Trick Jump Panel.
In one of the models for the town stages' Humans, there is a model for a thief and his bag that did not make it into gameplay. They may have been implemented for missions such as: Town Mission 9: Chase the Fleeing Car! and/or Town Mission 3: Emergency Order: Capture the Thieves' Cars!, but were simply rejected.
Sonic the Hedgehog (2006 Xbox Live Demo)
Sonic the Hedgehog (2006 Xbox Live Demo) was a demo released for the Xbox 360. Once, it was available through Xbox Live Marketplace. It is currently only available for re-download to the Gamertags who downloaded the demo when it was publically available.
The demo includes Sonic's first section of Kingdom Valley. The Action Stage, as well as the game ,itself contains some differences from the final version. It also contains the game's 2006 E3 trailer but without the voiceover.
- Different enemies, item placement, and no Medals.
- Rings are dispersed in a wider circle when Sonic is hit.
- Sonic immediately re-spawns after losing a life. The screen will not black out.
- Sonic never falls back from hitting a wall and never gets temporarily stunned from being clipped to the sides of the walls.
- Most trails of Rings can be used for the Light Speed Dash.
- Sonic falls from ceilings instead of being rooted to their surfaces (e.g. the high cave full of Egg Bombers).
- Camera angle shots were added in the beginning of the Action Stage.
- The camera control is much slower than in the final version.
- The Action Gauge starts out empty, but it can be filled by defeating enemies. However, it fills much slower than in the final version. The first of the three bottom-right squares are red, showing a non-existent Custom Action Level 1. The bar below the Action Gauge also has a small section of red filling it, in contrast to the final version where the gauge is always empty.
Visual and sound
- Title screen uses one of the last riffs from "His World" (Ali Taba. & Matty Lewis version) instead of the song's introduction.
- The title screen and pause screen's options refer to the demo as "Play Demo" and "Quit Demo" respectively.
- The controls are shown on the Action Stage's loading screen in the demo.
- The music and the screen will not fade out after losing the last life.
- The visual effects of the Homing Attack are a little different.
- There are no flashy effects for the Spin Dash.
- The Bound Jump's "shockwave" is mostly white with yellow edges instead of blue in the demo.
- Surfing on the wind paths in the demo does not produce the appearance of wind debris being stirred up from the character's feet.
- No voice sound effects except for subtitled scripts. There are also no scripts on the results screen.
- Pressing or on any option on the pause menu will not produce the "confirming" high-pitched sound effect in the final version. Instead, it will produce the "cancel" sound used for pressing "Start" or .
- There is no music for the result screen, although there are unused result music in the demo's files.
- 1-Ups rewards 0 points instead of 200.
- Light Speed Dashing earns a "Good!" bonus and the point increments increase by collecting more Rings via this way.
- The Light Speed Dash is configured properly with the Slide, unlike in the final version.
- Hitting a rock pile is worth 20 points, and hitting any of the scattered rocks gove 20 points each. In the final version, the rocks disappear immediately when scattered but the initial pile is still worth 20 points.
- The Egg Searcher wields three re-spawnable pods that are each worth 100 points. The robot itself is also worth 100 points. Any pods that the Egg Searcher is armed with upon its defeat will add to the total point score. Defeating an Egg Searcher when it is armed with all three pods earns a "Radical!" bonus in the demo version. This does not happen in the final version.
- Egg Bombers can crawl in mid-air.
- Homing Attacking an empty 1-UP capsules will get Sonic stuck in midair and then dropped down.
- Completing the Action Stage in twenty minutes and one second, or over will result in an S-rank, regardless of score.
- When using a Hint Ring while the characters continue to move, the text box will disappear before the in-game narrator can read it.
- In most cases, upon earning a "Good!", "Great!", and "Radical!" bonus in quick succession, the player will earn -2,112,941,584 points, causing the score to be maximized. Completing the Action Stage with this score will cause every factor besides the time to be maxed out.

TGS 2005 demo
The gameplay of the game was first shown off at TGS 2005 in a prototype stage. A number of differences was present due to the early stage of the game's development:
- In the demo, Sonic's character model is different: he looks a little more detailed and resembles his illustration in pre-rendered CG cutscenes. The final game features a much brighter, less detailed Sonic. His game model's animations are also different: Sonic's shoes are shiny and the surroundings are reflected in their surface.
- In the demo, the game is running slower, due to how early in development it was. Despite this, Sonic goes extremely fast when grinding.
- In the demo, the wooden containers do not have stars on them, unlike in the final game.
- Debug functions were used in the demo that did not make it into the final version, including freecam, and levitation.
- In the demo, a day-night cycle could be used via debug controls that were built in.
- In the demo, the Action Stage's assets are a little different from the final version.
- In the demo, Sonic's animations are unfinished.
- In the demo, Sonic seems to aim directly into the ground when Homing Attacking, unlike in the final version of the game where he Jump Dashes instead.
- In the demo, Sonic's victory pose is different. Here, he gives a thumbs up with the Sonic Heroes victory music playing in the background. Kingdom Valley also ends earlier because the Action Stage had not been finished at that time.
E3 Demo and trailer differences
The E3 demo containing both Sonic's Kingdom Valley and Silver's Crisis City has several differences from the final version, and the trailer showcased there:
- Unreleased characters arts for both Sonic and Silver.
- The first section of Kingdom Valley is similar to that of the final version, except when Sonic grabs the eagle it, takes him to the Super-Speed Stage, and not to Silver's section like in the final version.
- There is no voice for the characters.
- The loading screen depicts a blue screen with the Action Stage's name and the objective at the bottom, rather than an image of the Action Stage with control tutorials like in the final version. The "Now Loading" text also fades away instead of disappearing completely.
- The HUD is different, featuring a Sonic head for the character icon. Sonic's Action Gauge is also not used.
- Sonic and Silver have all their moves unlocked in the demo.
- Blaze's section was not included in demo's version of Crisis City.
- In the demo, Silver's speed increases the more Rings he collect, like Sonic. Both of them are also faster than in the final version.
- The sound effect for collecting a medal is completely different in the demo.
- In the demo, Sonic's Homing Attack works differently. When using it, he falls to the floor instead of dashing through midair. He also has multiple different animations for flips among other things, which are used with the White Gem in the final version.
- In the demo, Silver can fly while carrying objects, unlike in the final version.
- In the demo, Kingdom Valley has a big blue sky rather than an overcast one in the final game.
- In the demo, when the Goal Ring is touched, the game does not freeze to load data like in the final version. It also depicts a Mission Completed text.
- In the trailer of the E3 demo, the Castle Town seems lively than in the final version, with more people interacting with each other.
- In the demo, Crisis City has Eggman's robots instead of Iblis's Minions as enemies.
- In the demo, there are a few gramma errors in the dialogues.
- In the demo, the characters' text boxes are simple black rectangles, unlike in the final version.
- Crisis City and Kingdom Valley's background music are different in the demo.
- Despite the fact that this variant of "His World" is ultimately unused in Sonic the Hedgehog (2006), it is used in many of Sega's Sonic the Hedgehog TV advertisements.
- The New City glitch can be performed before proceeding to "Save the Archaeologist" mission as well, but the entered version is without the unused mission and the Flame Core and Crisis City warp gates.
- It is possible to score 50.000 points in the unused mission of New City.
- The Homing Attack used in the earlier demo of the game lets the player to instantly destroy multiple enemies, unlike in the final version.
- It should be noted that some of the game's beta elements are very similar to those in in Sonic Unleashed, like the day and night cycles, the Chao and ghost missions.
