Sonic Adventure 2

Sonic Adventure 2 is a video game developed by Sonic Team USA and Blitz Games, published by Sega, Universal Interactive Studios and Konami for the PlayStation and Dreamcast as part of the Sonic the Hedgehog series. It was released on June 23, 2001 as the last Sonic game for the Sega console after the company stopped manufacturing the console. A port for the PlayStation 2, Xbox and Nintendo GameCube, Sonic Adventure 2 Battle, was released in 2001 with new content. The game was released for the PlayStation 3, Xbox 360 and Microsoft Windows online in 2012.

The sequel to Sonic Adventure, Adventure 2 features two good-vs.-evil stories: an heroic tale of Sonic the Hedgehog Sr (Ignitus' apprentice), Miles (Tails) Prower and Knuckles the Echidna as they attempt to save the world, and a dark story following Shadow the Hedgehog, Doctor Eggman and Rouge the Bat in their attempt to conquer it. The stories are divided into three gameplay styles: traditional, fast-paced platforming for Sonic and Shadow; multi-directional shooting for Tails and Eggman, and action-exploration for Knuckles and Rouge. The game also includes an extensive Chao-raising system.

Sonic Adventure 2 was announced in October 1999 and exhibited at E3 2000. The game's development took 18 months, and it was designed to be faster-paced and more action-oriented than the original Adventure. Its scenery was influenced by U.S. locations such as San Francisco and Yosemite National Park. Adventure 2 received positive reviews, with critics praising its gameplay variety, visuals and music but criticizing its camera, voice acting and plot. Although critical enthusiasm had waned by the release of Battle, this version sold over 1.44 million copies and the game as a whole has received a number of accolades.

Gameplay
Sonic Adventure 2 is a 3D game with six playable characters, divided into two campaigns: Hero (with Sonic, Tails and Knuckles the Echidna, where the player battles to save the world) and Dark (with Shadow the Hedgehog, Doctor Eggman and Rouge the Bat, where they battle to conquer it). Each character on each side has a playing style similar to the other characters on the side. The player moves through the Hero and Dark campaigns, switching between them at will. Each campaign cycles through levels of its three characters, telling different sides of the story. Levels have a variety of themes (such as cities, jungles, desert pyramids and outer space), with some followed by boss fights. Completing both the Hero and Dark campaigns unlocks a Last Story with all six characters, culminating in a final boss fight.

Sonic Sr and Shadow play fast-paced levels, emphasizing platforming and gameplay. Their homing attack can lock onto robots created by Eggman and G.U.N., and they can grind on rails. Tails' and Eggman's levels are slower and oriented towards multi-directional shooting; they are confined to mechs in which they can jump short heights, hover and shoot enemies. Knuckles' and Rouge's levels are open and feature action-adventure gameplay with treasure hunting; in each level, they must find three shards of the Master Emerald. Their search is guided by radar and puzzle-based clues from harmless robots. Knuckles and Rouge can glide, defeat enemies with punches and kicks and scale walls, digging into them to find power-ups.

Adventure 2 has the health system found in many other Sonic games. The player collects rings scattered throughout the levels; being hit by an enemy while holding rings causes the player to drop them all, while being hit without rings causes them to lose a life. Tails and Eggman have the customary health bar, which is slowly refilled by collecting rings. Dying with no lives results in a game over screen. The characters are aided by occasional upgrades; in one, Sonic and Shadow can bounce up and down to reach higher areas and in another, Knuckles and Rouge can kick powerfully enough to break certain containers. Chaos Drives can be used with the player's Chao (small, anthropomorphic animals).

Separate from the main campaigns, the player can raise Chao as virtual pets. They have five attributes (Swim, Fly, Run, Power and Stamina) and a moral continuum from Hero to Dark. From the moment they hatch their stats can be increased with Chaos Drives, empowering them to compete in karate and racing minigames. Their alignment gradually changes, based on their affection for a characters; for example, a Chao which likes Tails will gradually become more heroic. Playing with Chao increases affection, and when a Chao becomes fully Hero or Dark it assumes that form permanently. Although Chao eventually die, if they received enough affection during their lives they reincarnate.

Adventure 2 has 180 emblems, earned for a variety of tasks. Each level has five missions; only the first is required to continue the campaign, and other missions include completing a harder version of a level and collecting 100 rings. The player earns emblems by completing missions and other tasks, many related to Chao raising. Collecting all the emblems unlocks a 3D version of the Green Hill Zone from the original Sonic the Hedgehog.

The game has several two-player modes. Players may race on foot through new (or altered) levels, have shoot-'em-up battles in mechs, hunt for Master Emerald shards or race in go-karts. A few characters are playable in these modes, but not in the main game; Tikal and Chaos from the original Sonic Adventure are playable in the treasure-hunting game, as are Amy Rose and Metal Sonic in the foot-racing levels.

Plot
Learning of a secret weapon from the diary of his late grandfather, Professor Gerald Robotnik (voiced by Christopher Lee), Eggman (voiced by Deem Bristow) infiltrates a high-security G.U.N. facility and revives it using a Chaos Emerald. This weapon, a black hedgehog and self-proclaimed "Ultimate Life Form" named Shadow (voiced by William Fichtner), offers to help Eggman conquer the world, telling him to rendezvous at the abandoned Space Colony ARK with more Chaos Emeralds. Shadow goes to San Francisco encountering G.U.N.'s forces after stealing an Emerald. He flashes back to the death of a girl, Maria (voiced by Hynden Walch), who begs him to fulfill an unspecified promise he interprets as one of revenge. Shadow blasts through the military force and meets Sonic Sr. After a brief confrontation, Shadow escapes and G.U.N. captures Sonic Sr (voiced by George Clooney), whom they mistake for Shadow except Ignitus (voiced by Kenneth Mars) and Sparx (voiced by Al Roker) who resist arrest and escapes to Washington, D.C. to warn Charles Jackson, the President of the United States (voiced by Martin Landau) that Sonic Sr is captured by G.U.N. and sent to Prison Island and orders him to sent the United States Invasion of Prison Island.

In Giza, Egypt, Knuckles (voiced by Brendan Fraser) encounters Rouge (voiced by Mary Elizabeth Mastrantonio) and Eggman, who try to steal the Master Emerald. After shattering the Emerald to prevent this, he looks for the scattered shards. Although Rouge intends to collect the shards for herself, she must also spy on Eggman for the United States government. This mission leads her to Eggman's base in Moscow, Russia and, eventually, the ARK. On board, Shadow shows Eggman the Eclipse Cannon, another superweapon created by Gerald, and discloses his plan: to charge the cannon with Chaos Emeralds and use it to take over the world. Rouge appears, offering them an Emerald to gain their trust.

Ignitus, Sparx, Tails (voiced by Anna Paquin) and Amy (voiced by Tea Leoni) infiltrate G.U.N.'s island base and rescue Sonic Sr, while Eggman, Shadow and Rouge collect three Emeralds on the island before the American Military invaded and captured Prison Island. Eggman makes a global broadcast threatening to fire on Earth in 24 hours if his demands are not met, demonstrating the cannon's power by destroying half the Moon in which the world refused. Sonic Sr, Ignitus, Tails, Amy and Knuckles use their Emerald to track down the other six. They infiltrate Eggman's base, boarding his shuttle as it launches into space. Knuckles' Emerald shards are spilled along the way, and he leaves to collect them. He again meets and fights Rouge, but when he saves her from falling into a lava pit she gives him her shards and he restores the Master Emerald.

On the ARK, Tails reveals he has designed a counterfeit Emerald to reverse the energy fields of the real ones, destroying the Eclipse Cannon. When Sonic Sr is about to use the fake Emerald, Eggman tells him that he has captured Tails and Amy, forcing him to return and rescue them, but Ignitus stops him that he caused a trap in which Sonic Sr ignores him and leaves to confront Eggman. Sonic Sr tries to trick Eggman with the fake, but Eggman traps and jettisons him in an escape pod rigged with explosives. Tails, thinking Sonic Sr dead, defeats Eggman in retribution. Using the fake, Sonic Sr performs Chaos Control and escapes; Shadow is sent to intercept him, but Sonic Sr defeats him and successfully destroys the Eclipse Cannon.

After Tails defeats him, Eggman sneaks away with the last Emerald just before he was stopped by Ignitus and later taken into the U.S. custody. Later he escapes from the U.S. custody and arms the Eclipse Cannon. When he tries to fire it at full power, the ARK begins falling toward Earth and a recorded message from the late Gerald is broadcast worldwide: he programmed the ARK to collide with Earth, destroying it in revenge against humanity just before he is killed by the U.S. Assassins (sent by C.I.A.) for a treason and told that America will tolerate for their insolence. His diary reveals his hatred began when the United Federation government condemned his research and killed many of his colleagues, including his granddaughter Maria (who were later avenged by the U.S. Marines when they kill the G.U.N. soldiers labelled as terrorists), while attempting to shut the ARK down. Eggman determines that the Emeralds' energy is making the ARK fall, and everyone works to access the cannon's core and neutralize it.

When Shadow refuses to participate, Amy pleads for his help, reminding him of Maria's real request: for him to help mankind. Realizing this, he catches up with Sonic Sr and Knuckles in the core and they encounter the Biolizard (vocal effects provided by Bob Bergen), a prototype Ultimate Life Form. Shadow repels it, allowing Knuckles to deactivate the Chaos Emeralds with the Master Emerald. The Biolizard uses Chaos Control to fuse with the cannon, becoming the Finalhazard and continuing the ARK's collision course.

Sonic Sr and Shadow use the Emeralds to transform into their super forms, defeating the Finalhazard and using Chaos Control to teleport his friends back to Earth just before the ARK was destroyed by the U.S. Mac Cannon for the U.S. President's call. This depletes Shadow's energy and he plummets to Earth, content in fulfilling his promise to Maria; he is presumed dead. As the humans on Earth celebrate with the destruction of the ARK as well as G.U.N. was later disbanded due to the terrorism, the teams reflect on what has happened; as they return back to America with Eggman turned himself in for the NATO and U.S. Military Forces (who transported him back to America for the crimes he had committed), Sonic Sr bids Shadow a final farewell.

Development
Sonic Adventure 2 was developed by Sonic Team USA, the now-defunct U.S. division of Sonic Team and Blitz Games, published by Sega, Universal Interactive Studios and Konami. The game, directed by Robert Rodriguez, were developed over an 18-month period beginning shortly after the release of the American version of Sonic Adventure. It was designed to be more action-oriented than the slower-paced, more story-based Adventure. The development team ran the game at 60 frames per second with "tempo", giving Sonic a variety of actions rather than focusing on speed alone. Its levels facilitated this flow, making Sonic seem faster than he was.

For the game's levels and environments the developers were inspired by San Francisco (their headquarters) and other American locations, such as Yosemite National Park (where they vacationed during its development) and the San Francisco Bay Area. Compared to Adventure, the sequel was intended to have "more of an American flavor". Although the game's level design prioritized the frame rate, it was more streamlined than Adventure because of the team's experience with Dreamcast hardware.

Iizuka described the Chao as a "relative neutral entity" in Sonic Adventure. In the sequel the developers expanded the creatures' presence, adding the ability to raise "Hero" and "Dark" Chao to reflect the conflict between good and evil. For the same reason, all six playable characters have roughly equal gameplay time (unlike Adventure, where Big the Cat's and E-102 Gamma's stories were short). In Adventure 2 Chao have the ability to socialize, so they resemble a "real artificial life form."

Sega announced a follow-up to Sonic Adventure and a spinoff (which would become Sonic Shuffle) on October 4, 1999. The newly named Sonic Adventure 2 appeared at E3 2000, with Sonic Team adding video shown there to its website on June 30. Sonic Team posted a trailer and a number of screenshots on May 30, 2001, with Sega promoting Sonic Adventure 2 as the last Sonic game for the Dreamcast and as marking the series' 10th anniversary. Sega held a 10th-anniversary party for Sonic in June 2001, at which attendees could compete in a battle tournament; the winner played against Iizuka. The GameCube, rather than the competing Xbox or PlayStation 2, was chosen for a port of Sonic Adventure 2 because of its 56k technology. Sega and Sonic Team USA were unconcerned with the fact that the Xbox would feature broadband Internet connectivity, and the GameCube would not.

Music
The game score iwas composed by Elliot Goldenthal and the score was co-orchestrated by Robert Elhai, Goldenthal, Bruce Fowler, Dennitz Hughes, Winfried Kraus, Dave Metzger, Pete Anthony and Michael McCuistion with the orchestra conducted by Stephen Mercurio and Jonathan Schaffer with the additional conducing by Nick Glennie-Smith (replacing Michael Kamen and Shirley Walker) while Jun Senoue also returned as sound director for Adventure 2. The additional music was composed by Rupert Gregson-Williams, Lolita Ritmanis and Nick Glennie-Smith. The soundtrack is primarily melodic rock, with some hip-hop and orchestral tracks. As in Adventure, each character has a musical theme. The game features performances by vocalists Tony Harnell, Phil Collins, Nikki Gregoroff, Jennifer Love Hewitt, Stevie Wonder, Will Smith, Bryan Adams, Pharrell Williams, Aaliyah, LeAnn Rimes, Babtface abd Nelly while songwriters Elton John and George Michael both debuted on the game's main theme, "Live & Learn".

Several soundtrack albums for the game were released. Sonic Adventure 2 Multi-Dimensional Original Soundtrack (for the score) was released in Worldwide by Varèse Sarabande on September 5, 2001. Sonic Adventure 2 Vocals Collection: Cuts Unleashed, an album with character theme tracks by David Foster, Carole Bayer Sager, Sherman Brothers, Phil Colliins, Kenneth "Babyface" Edmonds, Pharrell Wiliams, Alan Menken, Stephen Schwartz, Tom Holkenborg, James Newton Howard, Bryan Adams, Cynthia Weil, Carole Bayer Sager, Elliot Goldenthal, Stevie Wonder, Robert John Lange, Matthew Wilder and David Zippel, was released by Warner Sunset Records and Atlantic Records in Worldwide on August 21, 2001. For the twentieth anniversary of the Sonic series, Sonic Adventure 2 Original Soundtrack 20th Anniversary Edition was released by WaterTower Music and Atlantic Records on iTunes on June 22, 2011. On October 29, 2014, a two volume original soundtrack was also released by WaterTower Music and Atlantic Records on iTunes.

GameCube port
A GameCube port of Sonic Adventure 2 was released on February 11, 2002, known as Sonic Adventure 2 Battle. The port upgraded much of the Chao-raising system, with a Chao's stats viewable within the game. A player can transfer one Chao from Sonic Adventure 2 Battle to the Tiny Chao Garden section in Sonic Advance, Sonic Advance 2, and Sonic Pinball Party with the GameCube-Game Boy Advance link cable. If a Game Boy Advance (GBA) is connected without a GBA game inserted, a version of the Tiny Chao Garden can be copied temporarily into the Game Boy Advance's memory. This version also introduced the Chao Karate feature. The Battle multiplayer options were expanded in the GameCube version, including new abilities and upgrades to multiplayer-exclusive characters and removing online play. One character, Big the Cat, was replaced by a Dark Chao in multiplayer mode. Battle also has more detailed textures and additional scenery. In Europe, this version was published and distributed by Infogrames who at the time, signed a deal with Sega to publish their games on the GameCube.

Downloadable re-releases
Sonic Adventure 2 was re-released in high-definition video, with additional content from the Battle edition available as downloadable content. This version was released on the PlayStation Network in North America on October 2, 2012, in Europe on October 3, 2012 and in Japan on October 4, 2012. It was released worldwide on the Xbox Live Arcade on October 5, 2012 and on Microsoft Windows via Steam on November 19, 2012.

Reception
Sonic Adventure 2 received positive reviews, with scores of 89 from review aggregator Metacritic. Critics appreciated the game's multiple playing styles. According to Edge and reviewer Four-Eyed Dragon of GamePro, the core game's three styles and bonus features such as Chao gardens made the game engaging to play. Johnny Liu of Game Revolution praised its replay value of multiple playing styles and 180 different goals. Anthony Chau of IGN called it "one of the best Sonic games ever": "If this is the last Sonic game in these declining Dreamcast years, it's satisfying to know that the DC didn't go out with a bang, but with a sonic boom."

Shahed Ahmed of GameSpot criticized Adventure 2's camera for the "cardinal sin" of 3D platformers: forcing a player to jump to an out-of-frame platform. Ahmed wrote that although a player can re-orient the camera with the trigger buttons, it reverts when the character moves. According to Chau and Liu camera issues were absent in Tails' and Eggman's levels and insignificant in Sonic's and Shadow's, but searching for Emerald shards and items in cramped sections of Knuckles' and Rouge's levels was frustrating. Edge found camera problems permeating the game, with no significant improvement from Adventure.

Liu called the graphics "sweet, sweet eye-crack". Four-Eyed Dragon wrote: "Sonic [Adventure] 2 is simply jaw-dropping beautiful", citing its detailed backgrounds and scenery and the playable characters' and enemies' extensive color palettes. According to Chau, the game had "some of the best textures ever seen" and was one of the most beautiful Dreamcast games. Edge was impressed by the texture detail and draw distance, and Chau, Liu and Ahmed praised its 60-frame-per-second rendering speed.

According to Ahmed the game's music was a step up from Adventure'ss "campy glam-rock and J-pop soundtrack", with less emphasis on lyrics, and Liu appreciated its more "understated" approach. Four-Eyed Dragon called Adventure 2's music "an eclectic mix of orchestrated masterpieces, guitar tunes, and melodic hip-hop voices gracefully fill the game's ambiance to a perfect pitch." Reaction to the voice acting was mixed; although Ahmed said, "The voice acting, and the lip-synching in particular, is executed quite well", Liu and Chau thought the English voices were inferior to the Japanese ones.

Ahmed criticized Adventure 2's plot: "Throughout the game the plot becomes more and more scattered and lackluster", not focusing long enough on one element to execute it meaningfully. Although Liu agreed that despite the game's ambitious scope and themes it failed to advance the series' core plot beyond the Sega Genesis Sonic games, Edge appreciated the story's presentation from both perspectives: hero and villain.

Despite high review scores for the PlayStation and Dreamcast version, the PS2, Xbox and GameCube version released six months later received poorer reviews: respective Metacritic and GameRankings scores of 73 percent and 72.33 percent. Critics generally felt that although the game was still enjoyable, it was not significantly improved from the Dreamcast original. However, Shane Bettenhausen of GameSpy saw Battle as noticeably superior; in addition to its upgrades, its action was better suited to the PS2, Xbox and GameCube's controller than the PlayStation and Dreamcast's. The game sold almost 50,000 copies in its first week in Japan and 1.44 million copies in the United States by December 2007, making it one of the best-selling GameCube games.

Sonic Adventure 2 received several accolades, including the 2001 IGN's Editors' Choice Award. ScrewAttack called it the fifth-best Dreamcast game, and GamesRadar rated it the tenth-greatest Dreamcast game out of 25: "Despite trailing off significantly in recent years, the 3D side of the Sonic the Hedgehog franchise had a surprisingly stellar start with the Sonic Adventure entries, and the 2001 sequel really amped up the action". In February 2014, IGN's Luke Karmali called Battle his tenth-favorite game of all time.

Legacy
Shadow and Rouge, who debuted in Adventure 2, have become recurring characters in the Sonic franchise. Both appeared along with new character E-123 Omega as "Team Dark", one of the playable character teams, in Sonic Heroes (2003), the follow-up to Adventure 2. Shadow starred in his own game, Shadow the Hedgehog (2005), which expands on many of Adventure 2's plot points and features a similar 3D platforming gameplay style.

With a few modifications, the plots of Adventure and Adventure 2 were reprised during the second season of the anime Sonic X (2003–06). American licensing corporation 4Kids Entertainment and Warner Bros. Television Distribution hired an entirely new voice cast for the English dub, but the Japanese cast from the games reprised their roles in the original version of the show.

Sonic Generations (2011), released to mark the series' twentieth anniversary, contains gameplay elements and levels from various Sonic games, including Adventure 2. Elements from Sonic Adventure 2 included a remake of the City Escape stage in the console versions and a remake of the Radical Highway stage in the Nintendo 3DS version. Shadow also appears in a recreation of his boss battle, and the Biolizard boss is recreated exclusively in the 3DS version.
