Overview

Four years after his debut, Shadow got the spotlight. Shadow the Hedgehog was made in San Francisco by Sega Studios USA, the team that had built Sonic Heroes under the Sonic Team USA name, and released on GameCube, PlayStation 2 and Xbox in November 2005, a month before Japan.

Underneath it is still a 3D Sonic game, with loops, grind rails, rings, springs and homing attacks. On top of that Shadow can pick up machine guns, melee weapons, missile launchers and even traffic signs, jump on motorbikes and commandeer GUN walkers. Nearly every stage offers a Hero goal, a Dark goal and a plain run to the finish, and whichever you complete decides the next stage, the next scene and, after six stages, which of ten endings you get. See all ten and the Last Story finally explains where Shadow came from.

Critics hated a lot of it: the slippery controls, the mazes, the guns and the attempt at a grown-up tone. Players bought it anyway, more than two million of them by Sega’s count, and the game has grown a cult following that was rewarded in 2024 when Shadow Generations brought its villain back.

To destroy or to protect? Shadow the Hedgehog carries a dark past that is shrouded in mystery.

Under the headline “Hero or Villain?”, the North American box asks players to uncover the truth about Sonic’s arch-rival and work out who he really is, warning that the way you play will settle his future. Its captions sell speed mixed with shooting, a pile of missions with branching storylines and several endings, and a two-player battle mode.

Quick Answers

The short answers, with the detail further down the page.

When did Shadow the Hedgehog come out?

In North America on 15 November 2005, across Europe between 16 and 18 November 2005 and in Japan on 15 December 2005, on GameCube, PlayStation 2 and Xbox. More →

Who is Shadow?

The “Ultimate Life Form”, created fifty years earlier by Professor Gerald Robotnik on the Space Colony ARK. He debuted in Sonic Adventure 2, seemed to die at its end and turned up again, memory gone, in Sonic Heroes. More →

How many endings are there?

Ten, ranging from Shadow wiping out the alien invaders to Shadow planning to destroy the world, plus a true ending in the Last Story. There are 326 different routes through the game. More →

How do Hero and Dark missions work?

Most stages have a Hero mission (help GUN or Sonic’s friends), a Dark mission (help Black Doom or sometimes Eggman) and a neutral finish at the goal ring. The one you complete picks the next stage. More →

Who are the Black Arms?

Aliens from the Black Comet, which passes the planet every fifty years. Their leader, Black Doom, insists Shadow once promised him the Chaos Emeralds. More →

Why does Shadow carry guns?

Takashi Iizuka wanted to reach older players, and Shadow’s darker character let the team add weapons and vehicles that would not suit Sonic. Yuji Naka called it a “gun action” game. More →

Are the three versions the same?

Almost. The Xbox version drops the option for a second player to control Shadow’s partner, and only some PlayStation 2 releases let you switch between English and Japanese voices. More →

Did it sell well?

Yes, despite the reviews: Sega reported 1.59 million copies by March 2006 and 470,000 more in the US over the following year, at least 2.06 million in all. More →

Plot / Story

Shadow under the moon in the opening of Shadow the Hedgehog (2005)
Shadow under the moon in the opening.

Shadow the Hedgehog picks up Shadow’s story after Sonic Heroes. He knows his name and holds on to one memory: escaping through the ARK with Maria while GUN soldiers close in, and losing her. Everything else is a blank, and three groups claim they can fill it in.

Fire in the sky

Every fifty years the Black Comet comes close to the planet, and people had treated it as a reason for a festival. This time it brings an army. As Shadow broods outside the city of Westopolis, the Black Arms pour out of the sky and attack.

Their leader, Black Doom, speaks to Shadow by name and reminds him of a promise: bring me the Chaos Emeralds. Shadow has no idea what he means, but the Emeralds are clearly the key to his past, and everyone wants them. Black Doom wants them, Dr. Eggman wants them, and GUN, the army that raided the ARK fifty years ago, has no love for Shadow.

Hero, Dark or neither

From Westopolis on, you choose. Hero missions mean helping GUN and Sonic’s friends (and, once, Eggman against the aliens); Dark missions mean doing Black Doom’s or Eggman’s dirty work; or you can ignore everyone, grab the Emerald and head for the goal ring. Whoever you help, everyone else keeps shooting at you.

Each run is six stages long. Heroic choices steer Shadow towards the more heroic stages, villainous ones towards the darker stages, and the sixth stage decides the ending. Every route has its own name, 326 of them in all, and the cutscenes along the way slowly hand Shadow his memories back.

Back to the ARK

Two stages take place inside Shadow’s head. The Doom replays GUN’s attack on the ARK fifty years earlier, when the soldiers shut down Project Shadow, and pits him against the same Heavy Dog tank he faced back then. Lost Impact revisits happier days with Maria and Professor Gerald, until a security breach sets the Artificial Chaos loose and the pair flee across the colony on armed monorails.

Ten endings

The sixth stage ends with one of three final bosses, and the ending depends on which mission you clear. Serve the aliens and Shadow fights Sonic and the GUN Commander’s Diablon mech; side with the heroes and he takes on Black Doom himself; walk a middle path and Eggman’s Egg Dealer is waiting.

The endings run the full range. In the most heroic, Shadow sets out to wipe out Black Doom and his army. In the darkest, he resolves to destroy the whole planet. In between, some endings have Eggman convince him that he is merely an android copy of the real Shadow.

The Last Story

With all ten endings seen, the true finale opens. Shadow has every Emerald, and Black Doom uses their power to drag the Black Comet down onto the planet’s surface. A paralysing gas spreads from the comet, and Sonic, his friends and Eggman collapse while alien larvae close in to feed. Only Shadow can still move.

Black Doom explains the bargain: Gerald promised him the Emeralds in exchange for his blood, which went into creating Shadow. He tries to take control of Shadow through that bond, until the Chaotix find a message Gerald recorded for him. The professor admits his deal with the aliens and reveals that he built the ARK’s Eclipse Cannon to destroy the comet, asking Shadow to finish the job.

Freed, Shadow turns Super and chases Black Doom, now the two-headed Devil Doom, around the comet. Mid-battle, Eggman confirms that Shadow is the real thing, not an android. Victory leaves Shadow free to warp the comet back into orbit with Chaos Control and blast it apart with the Eclipse Cannon. On board the ARK he looks at a photo of Maria and Gerald, lets it fall and walks away.

How it was made

Our original page had no history section, so this one is new, built from Wikipedia’s cited development history, Sonic Retro’s development page and Sega Retro’s release data.

Shadow’s turn

Early Black Doom model for Shadow the Hedgehog (2005)
Black Doom’s first render, by Barret Meeker.

After Sonic Heroes, Sonic Team USA renamed itself Sega Studios USA and started on a spin-off. Around that time Sega ran an online poll asking which character deserved a game of their own, and Shadow won it, though Sonic Retro doubts the vote shaped the project much. Takashi Iizuka had wanted to do more with Shadow ever since Sonic Adventure 2.

Iizuka felt earlier Sonic games had been aimed at younger players and wanted to reach an older crowd, while also clearing up the mysteries left hanging about Shadow’s origins. The team drew on films such as Underworld, Constantine and the Terminator series, and decided Shadow’s darker personality could carry weapons and vehicles that would feel wrong in Sonic’s hands. Branching story paths, planned for Adventure 2 but cut for time, finally made it in.

Revealed at the Walk of Game

Screenshot released at the Walk of Game reveal of Shadow the Hedgehog (2005)
A screenshot released at the reveal.Image via Sonic Retro

On 8 March 2005 Sonic was inducted into the Walk of Game in San Francisco, and Sega used the ceremony to unveil the game. The trailer opened as a celebration of Sonic’s history, then bullet holes tore through the old footage and Shadow appeared, under the tagline “Hero or villain? You decide.” Sega formally announced the GameCube, PlayStation 2 and Xbox versions on 23 March.

From T to E10+

Guns, blood and some mild swearing first earned the game a Teen rating, and Sega asked that only players aged 13 and over try the show-floor demos. When the ESRB introduced its new E10+ category during development, Sega edited the Western release to fit: some of the swearing went, the GUN soldiers stopped bleeding and the aliens’ blood turned green. The result was the first Sonic game rated E10+.

New voices

Released on the same North American day as Sonic Rush, it was one of the first two games to use the English cast of 4Kids’ Sonic X dub, replacing the actors from the Adventure era to bring the games in line with the TV show; the change coincided with the death of Deem Bristow, the previous voice of Eggman. Many fans protested, but the cast stayed until 2010. The Japanese voices, already shared with the anime, did not change.

Language options vary. The Japanese and North American PlayStation 2 releases let you switch between English and Japanese voices, European PlayStation 2 copies do not, and the Xbox version simply follows the console’s language. The GameCube disc has room for only one voice track, matched to its region.

Seven songs

Shadow the Hedgehog (2005) E3 poster
E3 poster.

Jun Senoue gave each kind of ending its own vocal track: Crush 40’s “I Am… All of Me” as the main and final-boss theme, “Almost Dead” by Powerman 5000 for the darkest endings, Julien-K’s “Waking Up” for neutral ones, A2’s “Chosen One” and Magna-Fi’s “All Hail Shadow” for heroic ones, and Crush 40’s “Never Turn Back” for the finale, plus a remix of Eggman’s theme from Adventure 2.

A2’s “Chosen One” is itself a replacement. A2 included members of Sins of a Divine Mother, whose “Broken” had to go when Senoue could not find its singer to clear the rights, and a second planned song, Magna-Fi’s “Who I Am”, was lost to licensing problems.

Release

The game reached North America on 15 November 2005, France on the 16th, Germany on the 17th and the UK and the rest of Europe on the 18th, with Japan following on 15 December and the Korean PlayStation 2 version on 22 December. Prototype builds from May and September 2005 have since surfaced.

Firsts: what this game introduced

Plenty about Shadow the Hedgehog was new for the series.

1Shadow’s own gameThe first game with Shadow in the lead; the next would not come until 2024.
2E10+The first Sonic game rated E10+ by the ESRB.
3Branching storyThe first Sonic built around branching missions: your choices change the stages you play, with 326 routes and ten endings.
4Sonic X voicesWith Sonic Rush, released in North America on the same day (15 November 2005), one of the first two games with the 4Kids English cast.
5Black Doom and the Black ArmsDebut of the alien invaders and their leader, who returned in Shadow Generations.
6Guns for a heroA Sonic series hero picking up and firing guns was new. The motorbikes and GUN vehicles were not the first time Sonic’s cast took the wheel: Sonic Drift raced cars in 1994 and Sonic Adventure 2 had car chases.

Cheats & secrets

Our original page had no secrets section, so this one is new. Shadow the Hedgehog has no cheat codes worth mentioning; its secrets are earned by playing.

Unlock the Last Story

See all ten endings and the Last Story appears on the story menu. Its stage, The Last Way, cannot be picked from stage select, but Expert Mode also leads there.

Every route has a name

The game names and records each of the 326 routes you can take, so completists have plenty to hunt.

Two-player battle

Fight a friend on a vertically split screen across three special stages, as Shadow, two metallic versions of him or their alternative colours, knocking rings out of each other until one is beaten.

Partner co-op

Plug in a second controller on GameCube or PlayStation 2 and a friend can take over Shadow’s partner. Doom’s Eye, Eggman and Charmy cannot be controlled, and the Xbox version leaves the feature out.

Glitches, exploits and oddities

Sonic Retro documents one big bug, and plenty left on the disc.

Infinite Chaos Control

Stand on an active checkpoint, open its warp menu and trigger Chaos Control straight away. Shadow warps forward while the Hero gauge stays full, all the way to the end of the stage, though warping to a checkpoint during or after the trick crashes the game. It works on GameCube and PlayStation 2 only.

Gindows

Gindows debugger graphic left in Shadow the Hedgehog (2005)
Gindows leftovers.Image via Sonic Retro

Image files left on the disc belong to a debugging tool called Gindows, a mini-Windows lookalike much like the one found in a prototype of Rez.

Sonic in two-player?

The English voice files contain unused clips of Jun’ichi Kanemaru, Sonic’s Japanese voice, which seem to have been meant for Sonic as a playable two-player fighter.

Test stages

An unused test stage in Shadow the Hedgehog (2005)
An unused test stage.

Five unused test levels, named STG0000 to STG0003 and STG0005, sit in the GameCube version’s files.

Friendly fire

Hit a character on your side and your partner tells you off, and you lose points at the end of the stage. Eggman’s robots count as Hero or Dark targets depending on whether GUN or the aliens are also present, which makes Cryptic Castle confusing.

    Two bosses share their names with F-Zero machines: GUN’s Blue Falcon (Captain Falcon’s car) and the aliens’ Black Bull (Black Shadow’s). Whether that was deliberate is unknown, though Sega had co-developed F-Zero GX a couple of years earlier.

  • The two-player battle music is Radical Highway’s “Vengeance Is Mine” from Sonic Adventure 2, and The ARK stage plays a remixed “Highway in the Sky”, the theme of Final Rush.

  • One cutscene had Shadow say “hell”, and the word was cut before release.

Legacy

Sega judged the sales not big enough to turn Shadow into a series of his own. It never got a modern port, but it kept its fans, and in 2024 both Shadow Generations and the third Sonic film went back to it.

Second opinions

Looking back after Shadow Generations, Kotaku’s Kenneth Shepard found a pretty solid 3D Sonic with interesting ideas, praising the branching story while agreeing the shooting is frustrating and the vehicles pointless. Eurogamer’s Paul Cecchini called it fine, with some cool ideas, and noted how rarely Sega had mentioned it since.

Sales & reviews

Sales

Reviews did not stop the game selling. Sega reported 1.59 million copies from launch to the end of March 2006, and another 470,000 in the US over the following year: at least 2.06 million. It joined the Player’s Choice, Greatest Hits and Platinum budget ranges, which needed strong sales to qualify.

The “mature” makeover took the most flak. Game Informer’s Matt Helgeson thought the adult Sonic both silly and a letdown for long-time fans, and Eurogamer’s Tom Bramwell decided the darker edge was not aimed at him. Nintendo Power’s Steve Thomason disagreed, giving it 8 out of 10 and finding the edgier tone mostly worked and the weapons simply fun.

Controls drew the most specific complaints, especially a homing attack that could fling Shadow into a pit. GameSpot’s Greg Mueller found the guns close to useless with no proper lock-on or manual aim, and IGN, 1UP and Game Informer all criticised the shooting and vehicles. Level design split opinion, from “disastrous” at Game Informer to Official Xbox Magazine’s view that fans of Sonic Heroes would enjoy the big stages. Almost everyone liked the replay value of all those routes, though GameSpot doubted the play was fun enough to go through it many times.
