Shadow must journey into his past, confront his painful memories, and unlock new dark powers to save the world.

— Tagline

Shadow Generations (シャドウ ジェネレーションズ, Shadō Jenereeshonzu^?) is a video game in the Sonic the Hedgehog series developed by Sonic Team and published by Sega that features Shadow the Hedgehog as the main protagonist. It is the first title in the series to star Shadow since Shadow the Hedgehog (2005) and homages that and other games with the character in a major role. The game's plot runs parallel to that of Sonic Generations (2011) and centers on Shadow as he faces Black Doom, who was originally the main antagonist of Shadow the Hedgehog.

The gameplay of Shadow Generations combines elements from the original Sonic Generations and Sonic Frontiers (2022). The player controls Shadow in re-imagined stages from previous games that are structured into two levels each, which shift between side-scrolling and 3D gameplay. As the game progresses, Shadow gains abilities known as "Doom Powers" that let him traverse different obstacles. The hub world is White Space from Sonic Generations, which this time is a fully explorable 3D world with challenges and collectibles that include concept artwork and music from prior titles.

Shadow Generations is not a standalone game, but is instead bundled with a remaster of Sonic Generations in Sonic X Shadow Generations, which was released on 25 October 2024, with players who pre-ordered the Digital Deluxe Edition gaining access to the game three days earlier. Shadow Generations was well-received upon release, amassing praise for its fan service and replay value, but criticism for occasional technical issues and the Doom Powers' mechanics.

Plot

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

Shadow faces Doom's Eye at the Space Colony ARK.

Haunted by memories of his past, Shadow the Hedgehog suspects the Black Arms have returned after their defeat and hitches a G.U.N. Space shuttle to the Space Colony ARK after being notified of an anomalous biosignature there. While investigating, Shadow encounters Doom's Eye, the "third eye" of the Black Arms' leader Black Doom, who transports him to a distorted Radical Highway known as the Doom Zone. After attacking Doom's Eye and grabbing a mysterious emblem, he returns to the ARK, where he finds the fake Chaos Emerald made by Tails. Soon after, however, the Time Eater appears and drags Shadow to White Space.

In White Space, Shadow notices a large Black Arms satellite, the Black Moon, hovering in the air. He also meets E-123 Omega, who was tracking the Time Eater before he was pulled into White Space too. While traversing the ARK again, Shadow suddenly manifests new powers by growing a pair of wings, which disappear as he returns to White Space. As he questions his new abilities, Shadow is shocked to see Maria and Gerald Robotnik far away, but dismisses the sight as a hallucination. He then finds a Sealing Device that unlocks the first of his Doom Powers, the Doom Spears. White Space then expands with a new area.

Shadow traverses Rail Canyon and is pulled into a Doom Zone again, this time collecting a Doom Gear to open a Sealing Device and learn Doom Blast. He then runs into Orbot and Cubot, who were left behind by Doctor Eggman and request Shadow's help finishing a rocket ship to escape White Space. Eventually he faces the Biolizard, whose defeat causes a new area of White Space to appear and the Black Moon to rend. Doom's Eye returns and projects Black Doom, who reveals to Shadow that he survived their last fight and intends to exploit the Time Eater's anomalies to accelerate the rebuilding of the Black Arms. Shadow demands that Black Doom show himself, but the alien overlord mysteriously states that they will not battle again until Shadow has been "perfected." Shadow then obtains Doom Surf.

Shadow explores the new area, visiting Kingdom Valley and coming across Big the Cat, who was following Froggy when he found himself in White Space. Shadow then visits Sunset Heights, where he is pulled into another Doom Zone. Upon his return, Shadow reunites with past versions of Maria and Gerald. He initially considers finding a way to change their fates, but ultimately decides to focus on defeating Black Doom. He then faces Metal Overlord, causing White Space to expand and the Black Moon to sprout tendrils. When Shadow comments that the satellite has the same energy as his Doom Powers, Gerald explains Shadow's linkage to Doom and reveals that as Shadow grows stronger, so does Doom; if left unchecked, Black Doom will either enslave Shadow's mind or take over his body and make it his own. Shadow assures that he will use these Doom Powers against Doom.

Shadow facing off against Sonic.

With a new ability, Doom Morph, Shadow explores Chaos Island. Afterwards, he encounters Sonic, who challenges Shadow to a fight for his Chaos Emerald so he can use it against the Time Eater. Shadow is tempted to use his Doom Powers against him, but does not, and Sonic ultimately wins the fight and leaves with the Emerald. However, when Rouge arrives and chastises Shadow for his defeat, the latter reveals that Sonic took the fake Emerald, intending to have Rouge swap it out for the real one once Doom is defeated. Soon after, Shadow fights Mephiles the Dark, preventing him from restoring himself to the timeline.

Shadow reunites with Maria and Gerald, but Black Doom arrives to confront them. The interaction leaves Shadow almost overcome by hatred and corrupted by his Doom Powers, but Maria manages to quell his anger. Shadow eventually obtains Doom Wing, the last of his Doom Powers. The Black Moon fully mutates, pulling White Space into the Doom Zone. After a final reunion with Gerald and Maria, Shadow flies to the Black Moon and travels through the corrupted Radical Highway, where he and Black Doom finally come face-to-face. Black Doom transforms into Devil Doom as he and Shadow fight through the distorted city, then evolves into Neo Devil Doom. However, Shadow has grown too strong for Black Doom to control, and using his Chaos Emerald and newfound Doom Powers, he defeats Black Doom once and for all.

Shadow and Rouge preparing to go help Sonic.

With Black Doom defeated, the Black Moon crumbles and Shadow loses his Doom Powers. With Rouge notifying him that Sonic is about to face the Time Eater, Shadow gives her the Chaos Emerald to swap it with the fake one and reunites with Gerald and Maria, only to discover that they are slowly disappearing back to their own time as a result of Doom's control over White Space dissipating. A panicked Shadow considers stopping Rouge and using Chaos Control to prevent them from leaving, but Maria stops him, saying that she and her grandfather do not want to be held frozen in time and encouraging him to move on because his friends need his help. She prevents him from warning her of her fate, assuring him that they will see each other again and that she will always be in his heart. Once she and Gerald vanish, Shadow leaves, shedding a tear that flies to Rouge's cheek as he skates past her.

Gameplay

Shadow grinding on rails in Space Colony ARK

The gameplay of Shadow Generations is similar to that of Modern Sonic's gameplay from Sonic Generations, with elements from Sonic Frontiers, featuring both 3D movement along with the occasional 2.5D side-scrolling section throughout the stages. As such, Shadow retains many of the same abilities as Modern Sonic, including the Spin Jump, Homing Attack, Stomp, Boost, and Air Boost.

While Shadow is unable to use the Light Speed Dash or Drift, he has a few different abilities which make use of his various Chaos powers. One of those is the Chaos Snap, Shadow's variant of the Homing Attack, which allows him to teleport to enemies while ignoring any obstacles. He can also fire Chaos Spears to stun enemies and hit distant targets. His most prominent Chaos power however, is Chaos Control. In addition to the Boost Gauge, which is filled by collecting Rings, Shadow has another gauge known as the Chaos Gauge, which is filled by defeating enemies. When the Chaos Gauge is full, he can activate Chaos Control, which stops time for 5 seconds. This allows him to make use of various shortcuts, such as traversing missiles or passing under fans blowing upwards. Under Chaos Control he can also perform the Chaos Dash, a move similar to the Light Speed Dash which allows traversal across a trail of green energy. While the ability is active, the in-game timer is paused, while a small timer appears above Shadow's head, reminding the player of the time remaining before the ability wears off.

In addition to his Chaos powers, Shadow gains access to five different Doom Powers throughout his adventure.

• Doom Spears allows Shadow to fire up to five Chaos Spears at once using lock-on cursors. This works the same as the normal Chaos Spear.
• Doom Blast allows Shadow to use his Chaos Snap to launch Black Arms enemies upwards, aim a cursor, and send them flying in that direction, teleporting to their new location. This can reach new areas.
• Doom Surf allows Shadow to surf across water on a manta ray-like construct. On water, the Quick Step becomes a Spin Attack, which can destroy or launch objects out of the water. Boosting can only be performed when first summoning the ray.
• Doom Morph allows Shadow to traverse Corruption slime by transforming into a squid-like form. This form is activated by touching a Morph Ball, after which Shadow can swim through Corruption even on walls or ceilings. He can move or attack with short Boosts, and can target Morph Balls to grapple them with a tentacle, allowing him to swing from them or shoot through them and into the air.
• Doom Wing is an ability akin to Super Sonic. It requires 50 Rings and is activated by pressing both Quick Step buttons. While active, Shadow is invincible and has endless Boost on the ground. He can also Boost through the air in order to glide, which depletes the Boost gauge and can be done as long as he has Boost. However, his Ring count slowly decreases over time, and the ability deactivates if he runs out. Before entering a Stage, Doom Wing can be enabled or disabled, which affects the time records of that Stage.

Controls

Shadow Generations uses a similar control scheme to Sonic Frontiers, though a legacy control scheme option is available. For the PC version, it is also possible for the player to customize the button mapping.

Stages

There are six main stages in Shadow Generations. Much like Sonic Generations, Shadow plays through re-imagined versions of past games featuring him, but also games chronologically set after this title. Takashi Iizuka explained that there are Stages from future games simply because the development team wanted to include games all the way up to Sonic Frontiers. The Stages in Shadow Generations are connected by an Open Zone hub area in White Space, which contains its own items, collectibles, and characters. Each Stage has two Acts like Sonic Generations, with Act 1 being set in a fully 3D environment and Act 2 (except for Radical Highway) set in a 2.5D side-scroller perspective.

As part of the "Sonic the Hedgehog 3 Movie Pack", a Tokyo stage based on the location of the same name was added to the game on December 12, 2024.

No.	Stage	Original appearance
1	Space Colony ARK	Sonic Adventure 2 and Shadow the Hedgehog
2	Rail Canyon	Sonic Heroes
3	Kingdom Valley	Sonic the Hedgehog (2006)
4	Sunset Heights	Sonic Forces
5	Chaos Island	Sonic Frontiers
6	Radical Highway	Sonic Adventure 2
7 (DLC)	Tokyo	Sonic the Hedgehog 3 (movie)

Bosses

The game features four boss battles against foes from previous games. Just like in Sonic Generations, the player must first unlock Boss Gates by clearing Challenge Acts in order to obtain Boss Gate Keys; all Challenge Acts must be cleared to finish the game. Defeating each boss unlocks more areas of White Space.

No.	Boss	Location	Original game
1	Biolizard	Cannon's Core	Sonic Adventure 2
2	Metal Overlord	Final Fortress	Sonic Heroes
3	Mephiles the Dark	Dusty Desert	Sonic the Hedgehog (2006)
4	Devil Doom	Doom Zone	Shadow the Hedgehog
	Neo Devil Doom		Shadow Generations

Other modes

Time Attack

In Time Attack 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. In the console version, Time Attack can only be done online, and only the eighteen main Acts can be played for a top time.

Unlockable collections

Music

Music can be unlocked by completing some Challenge Acts or opening yellow Collection Boxes. The player can view the unlocked music by going to the Collection Room. The music for each stage in the game can be replaced by any unlocked music.

There is a total of eighty-nine unlockable tracks; The first forty being obtainable in-game, with the remaining forty-nine tracks being obtainable by downloading the Digital Deluxe DLC:

Art

Art can be unlocked by completing some Challenge Acts or opening blue Collection Boxes. The player can view the unlocked art by going to the Collection Room.

Differences from Sonic Generations

Gameplay features

• Unlike in Sonic Generations, where the Boost Gauge can be refilled by both collecting Rings and defeating enemies, Shadow can only refill the Boost Gauge with Rings, like how Sonic does in Sonic Unleashed, while defeating enemies fills up the Chaos Gauge instead.
• The Drift and Light Speed Dash abilities are not present in Shadow Generations, with the respective buttons used to activate them in Sonic Generations being used to activate Chaos Control and Chaos Spear instead. However, the Chaos Dash, which Shadow has while under Chaos Control, is functionally identical to the Light Speed Dash.
• Shadow has the Double Jump, rather than Modern Sonic's Jump Dash.
• When the controls are set to "Legacy", only the button used to activate Shadow's Boost is changed. The Chaos Snap/Homing Attack always uses the //[LEFT CLICK] buttons to activate.
• Skills and the Skill Shop do not appear in Shadow Generations.
• Instead of collecting five Red Star Rings, each level instead features three of a new collectible known as Collection Keys. These are gears with icons featuring green books, yellow music notes, and blue painter's palettes which are used to open chests in White Space.
• Unlike the Red Star Rings:
  • Collection Keys are also present in Challenge Acts.
  • Replaying through a level will show a faint version of Collection Keys that have already been collected, whereas the Red Star Rings completely disappear from the level once they have been found.
• A different ranking system is used.
  • The player is now able to get an S-Rank with a clear time fast enough while the Perfect Bonus, which boosts the score rank by one, is absent.
  • Maximum Ring score available is drastically decreased, from 5,000 points to 1,000. In addition, Rings no longer participates in the score tally in the Boss Battles.
  • S-Rank Border drops from 50,000 to 40,000.
• Doom Wing can be enabled or disabled, and clear times for both are counted separately.
• Shadow Generations contains extra Hard Mode variants of certain Missions. However, these are counted as separate.
• Shadow Generations does not have a Life system, whereas Sonic Generations allows the player to toggle it on or off in the settings.
• Shadow Generations has several additional options not present in Sonic Generations:
  • There are various options related to the in-game camera, including moving it, its distance, angle, and sensitivity.
  • As with Sonic Frontiers, the player can adjust their deceleration rate when stopping.
• Unlike Sonic Generations, where the player can jump off a Zip Line, Shadow Generations does not allow the player to do so.
• Unlike Sonic Generations, where the player can only perform an Air Boost forward, Shadow Generations allows the player to perform an Air Boost at any direction, akin to Sonic Frontiers.

Stages

• White Space in Shadow Generations is presented as a 3D, open hub world, inspired by the open-zone design of Sonic Frontiers, whereas Sonic Generations uses a 2D, side-scrolling hub world.
  • Short challenges can be found in White Space, which include either collecting a set amount of Rings in a short time or collecting clocks to refill a depleting timer.
  • Chests can be found and unlocked with Collection Keys - green chests unlock pieces of Shadow's backstory, yellow chests unlock music tracks, and blue chests unlock new art pieces.
  • 80 Machine Parts are scattered across White Space. These can be found and delivered to Orbot and Cubot for collection item rewards.
• Act 1 of every stage is completely 3D while Act 2 (except for Radical Highway's) in completely 2D, wheras in Sonic Generations, Act 1 is completely 2D and Act 2 is a mix of 3D and 2.5D.
• Each act of every stage has only two Challenge Acts instead of five. Additionally, the gates for Act 1 and Act 2's challenges are separated, since Shadow does not swap with another character in the hub world.
• Each stage has two Boss Keys, one for each act, rather than only one.
• Boss Keys are obtained once both challenges for an act are completed, while in Sonic Generations, only one Challenge Act in either Act 1 or Act 2 has to be completed to get the Boss Key for that stage.
• Every Challenge Act in Shadow Generations is mandatory to beat the game, while Sonic Generations only requires as few as nine to progress.
• Checkpoints now exist in all Boss Battles, though in most cases they do not appear in physical form like Star Posts. If Shadow gets knocked out during the latter phases, the battle resumes from the start of that phase instead of starting the whole battle over. In Sonic Generations the checkpoints only exist in the battle against Perfect Chaos.

Appearance

• Shadow Generations uses the Hedgehog Engine 2 as its engine, as with Sonic Forces and Sonic Frontiers, whereas Sonic Generations uses the original.
• Certain sections of the levels in Shadow Generations feature transitions from standard gameplay into cinematic scenes and vice versa mid-level, similar to the Real-Time Interaction sections of Modern Sonic and the Avatar's levels in Sonic Forces. This does not occur in Sonic Generations, though certain points of levels do feature dynamic camera angles.
• There is mid-level banter between the characters in Shadow Generations, while in Sonic Generations, such banter is only present during the final boss.
• The in-game HUD, while similar thematically, has a completely different design.
• Hints are given through Hint Rings, rather than by Omochao.
• Before a boss battle begins, the loading screen shows the name of the boss, while in Sonic Generations, it only says "Rival Battle" or "Boss Battle".
• For boss battles, a Health Gauge for the enemy is now in the HUD on the top of the screen, while in Sonic Generations it is completely invisible.
• The level names above the stage entrances and Boss Gates do not turn gold when the player clears the stage with an S-rank.
• The level names also can be seen during cutscenes, unlike in Sonic Generations.
• The music the plays when clearing a stage differs slightly depending on the player's rank, with different jingles for a D or C-Rank, a B or A-Rank, and an S-Rank.
  • There is also no looping results theme that plays afterwards, unlike Sonic Generations. It is possible to be the homage of Shadow the Hedgehog, due to the jingle being a remix of the Result Screen jingle from the latter game.

Miscellaneous

• The player cannot play Shadow Generations by using the Directional Pad as a secondary Control Stick, unlike Sonic Generations.
• Cutscenes can be paused by pressing the start button, whereas Sonic Generations' cutscenes cannot be paused.

Cast

This section is about the cast of Shadow Generations. For the cast section in the rewritten and re-recorded remaster of Sonic Generations, see Sonic X Shadow Generations#Cast.

In the English dub, this is the first game where Ben Diskin, Ray Chase, and Robbie Daymond respectively voice Black Doom, Metal Sonic, and Mephiles, as well as the first time that the three characters have voice acting in languages other than English and Japanese. It is also the first time Roger Craig Smith voices Omega in a game, after previously voicing him in animated shorts.

In the Japanese dub, this is the first game where Kotaro Nakamura, Dr. Eggman's current Japanese voice actor, voices Gerald Robotnik.

In the French dub, despite Marie Millet reprising her role as Cream and Charmy in the rerecorded Sonic Generations campaign, she does not reprise her role as Maria from Sonic X, with Anissa Bellone voicing her instead.

In the Italian dub, this is the first game where Ilaria Silvestri voices Rouge, reprising her role from Sonic Prime. Similarly, Felix Spieß, Shadow's German voice actor from Sonic Prime, reprises his role, following the death of Shadow's previous voice actor, Klaus Lochthove, in August 2023.

In the Spanish dub, this is the first game where Carlos Calvo voices Cubot, replacing Xadi Mouslemeni Mateu.

Keanu Reeves, Shadow's voice actor from the live-action films by Paramount Pictures, reprises his role as part of the Sonic the Hedgehog 3 DLC stage. However, unlike the rest of the game, Reeves's voice is used in all language dubs, even outside of English, meaning that the skin isn't voiced by Toshiyuki Morikawa, Jean-Pierre Michaël, Claudio Moneta, Benjamin Völz or Sergio Zamora.

Development

Shadow the Hedgehog first appeared in Sonic Adventure 2, becoming very popular with fans and a recurrent character in the series. Prior to Sonic X Shadow Generations, he had protagonized his own eponymous game that was released in late 2005 to mostly negative reviews.

After the release of Sonic the Hedgehog 2 by Paramount Pictures, Sonic Team wanted to get a game starring Shadow out before the third movie's release, since he would be playing a big part in it. The development started while Sonic Frontiers was being worked on, since Sonic Team had been expanding throughout the past couple of years. It allowed a small portion of developers to work on both games along with Sonic Superstars.

Takashi Iizuka, head of Sonic Team, suggested the idea of a new game starring Shadow in June 2023, but otherwise gave no confirmation that one was in development. It would not be until January 31 of the next year where in Sony's State of Play, it was revealed to the public. It is the second time a 2010s game was remastered for newer consoles, following Sonic Colors: Ultimate in 2021. Unlike Sonic Colors: Ultimate, which was developed by Blind Squirrel Games, Sonic X Shadow Generations was developed by Sonic Team. Iizuka later established that the story of Shadow Generations will share a universe with the story of Sonic Generations involving the Time Eater.

Soundtrack

In an interview for Good Vibes Magazine, Iizuka revealed that Jun Senoue from Crush 40 will be in charge of the soundtrack for the game.

The music for trailer version of the Kingdom Valley Act 1 was officially released on various digital platforms on July 25, 2024, under the name of Richard Jacques' Audissi Studios.

On 8 August 2024, the music for Space Colony Ark Act 1 was officially released, as a partnership between Jun Senoue and musician TeddyLoid.

On 20 August 2024, on the release of the Shadow Generations "Doom Powers" trailer, musician RichaadEB announced being the arranger of a "Supporting Me" remix for the Biolizard boss fight.

On 5 September 2024, the music for Chaos Island Act 1 was officially released, the music is remixed by R.B.U.

On 10 October 2024 the official soundtrack was revealed to be called Sonic X Shadow Generations Original Soundtrack: Perfect | Reflections and was made available for pre-order. It released on 25 December 2024.

Promotion

On 31 January 2024, Sonic X Shadow Generations was first announced during Sony's State of Play.

On 14 May 2024, it was announced that an upcoming 2D animated special focused on Shadow titled Sonic X Shadow Generations: Dark Beginnings will be released in Fall 2024.

On 8 June 2024, a trailer on Summer Game Fest was shown which was instantly released on YouTube. With it, it was announced that there would be multiple bonuses available: Physical pre-order, and a Digital Deluxe version. Along with the Sonic Adventure legacy skin for the Sonic Generations campaign, the Physical pre-order bonus will give the buyer Gerald Robotnik's Journal, a physical book that has details of his life before Shadow, and what lead to his creation. PlayStation owners will also get extended and deleted scenes from Sonic X Shadow Generations: Dark Beginnings.

The Digital Deluxe Edition contains many more features, like a Terios Skin for Shadow, which is based on one of his early designs from Sonic Adventure 2, an extra BGM pack, and a digital art book and soundtrack all while getting to play the game three days early on all platforms (October 22nd as opposed to the 25th). However, getting the Digital Deluxe Edition on the Nintendo Switch will not allow players to play it early.

There will also be an additional character skin and level for Shadow that is set to release in Holiday 2024.

On 19 July 2024, it was announced on their social media that all pre-orders from the physical release will have the Japanese box art as a reversible cover.

On 18 September 2024, an officially endorsed video from Terminal Montage parodying Shadow's life was released. The video was sponsored by Sega to promote the game and recap Shadow's story to a new audience through a comedic-lense.

On 24 September 2024, it was confirmed that the game would receive an additional stage and skin based on the upcoming Sonic the Hedgehog 3 movie, complete with Keanu Reeves voicing the skin based off Shadow's appearance in the film.

Trivia

• The Terios skin is based on an early concept version of Shadow from Sonic Adventure 2, who was known as "Terios" during development.
  • This is the second game to feature a character skin of an unused concept design, the other being the Rabbit skin in Sonic Superstars which was based on an early design of Sonic. In an interview with Takashi Iizuka from Sonic Stadium, he stated that Ohshima's willingness to put in the Rabbit skin was the catalyst for the Terios skin.
• Excluding cameos, this game marks the first physical appearance of Black Doom and Metal Overlord since Shadow the Hedgehog and Sonic Heroes respectively.
  • It also marks the first time Mephiles the Dark appears in a mainline game since Sonic the Hedgehog (2006).
  • It also marks the first time Maria and Gerald physically appear in a game since Shadow the Hedgehog.
  • It also makes the first instance where Metal Sonic (though as Metal Overlord) have voice lines since Sonic Heroes.
• This is the first mainline entry since Sonic Unleashed to contain Humans other than Doctor Eggman.
• In the Shadow Generations DLC, in the reveal trailer, if one looks closely in Tokyo, a billboard on a city says "ROUGE".
  • Ironically, Rouge didn't appear in Sonic the Hedgehog 3.
  • Rouge is the only playable character from Sonic Adventure 2 who has not been confirmed to appear in Sonic the Hedgehog 3.
  • This is comparable to an Easter Egg in the Sonic the Hedgehog movie, as on the Zillow site, there is a woman named Amy Rose.
  • The Shadow Hedgehog DLC is the first instance of characters and locations from the Sonic the Hedgehog movie series being included in a Sonic the Hedgehog console game.
• Shadow re-encountering both Maria and Gerald is coincidentally and slightly reminiscent of "I Am", from Archie Sonic the Hedgehog #171, a story written by Ian Flynn, who likewise writes for Shadow Generations.
• The dialogue Shadow has with Sonic before their battle references their previous fights in Sonic Adventure 2 and Sonic Heroes.
• The Japanese and English versions contain minimal changes to the script, marking it the first time since Sonic and the Black Knight that a mainline 3D entry received no major story or dialogue differences between the English and Japanese scripts.
• During one dialogue, Maria said that she only saw Shadow drinking coffee. This is a possible reference to the Sonic Twitter Takeovers, where Shadow has a fascination for coffee beans, which was later referenced in The Murder of Sonic the Hedgehog.
• This is the first game since Shadow the Hedgehog to have a final boss theme performed by Crush 40.
• This is the first game to have Sonic only make an appearance in a cutscene.
• This is the second time Shadow sheds a tear. The first was in Sonic Adventure 2, and its Battle port.
  • This also marks Rouge as the second character to ever see Shadow crying after Amy in Sonic Adventure 2 and its Battle port.
