Sonic Adventure (ソニックアドベンチャー Sonikku Adobenchā?) is a platform video game developed by Sonic Team and published by Sega for the Dreamcast as the first video game to be released for the system. It was originally released for the Dreamcast in 1998, with enhanced ports of the game being released in 2003 for the Nintendo GameCube and in 2004 for Microsoft Windows. It has since been re-released as a downloadable game for Xbox 360 via Xbox Live Arcade, and PlayStation 3 via PlayStation Network in 2010.
Taking place on a fictional island connected to a city, the game follows the adventures of the protagonist Sonic the Hedgehog. An ancient entity named Chaos is released by series villain Doctor Eggman and plots to steal the seven Chaos Emeralds for the entity. Sonic is joined by his best friend Miles "Tails" Prower, Amy Rose, who views Sonic as her love interest, Knuckles the Echidna, who plans to reassemble the Master Emerald, Big the Cat, a cat who attempts to rescue his frog friend, and E-102 Gamma, one of Eggman's robots.
Sonic Adventure received generally positive reviews from critics, who praised the game's graphics, gameplay, and soundtrack. The game would later go on to become the best-selling Dreamcast game. A sequel, titled Sonic Adventure 2, was released in 2001 for the Dreamcast.
Sonic Adventure is a platform game in which the player controls six different characters: Sonic the Hedgehog, Miles "Tails" Prower, Knuckles the Echidna, Amy Rose, Big the Cat and E-102 Gamma. They must stop Doctor Eggman from stealing the seven Chaos Emeralds and feeding them to Chaos, a monster known as "the God of Destruction". The first in the Sonic the Hedgehog series to feature free-roaming 3D gameplay, Sonic Adventure features two game modes: Adventure and Trial. There are different goals for each character in the game: Sonic involves high speed gameplay, while Tails must reach the end of the level before Sonic does and Knuckles searches the area for shards of the Master Emerald. Each of the three characters retain many of their trademark moves from previous Sonic games, such as Tails being able to fly for short periods of time, and Knuckles being able to glide through the air, though they can use updated techniques as well. The rest of the playable cast is rounded out by Amy, who must use her hammer to escape from Eggman's E-100 Zero robot chasing after her, Gamma, who must use its laser beam to shoot through levels to reach a target, and Big, who fishes in efforts to find his friend, Froggy.
The "Adventure Mode" is a one-player game which consists of two areas, the "Adventure Field" and an "Action Stage". The Adventure Field contains several "Events" that are encountered in the course of the story, while the Action Stages have each character fulfilling a goal to clear the stage. Players may also find hidden Chao Gardens, a protective environment inhabited by Chao, a sort of virtual pet. The player can hatch, raise and interact with a Chao. Chao can be taken with the player by downloading the minigame Chao Adventure to their VMU, or in the GameCube version, a Game Boy Advance with Sonic Advance or various other Game Boy Advance Sonic games. The player can also raise their stats by giving them small animals that they found by defeating the robots, which improves their performance in Chao Races. There are also eggs hidden throughout the Adventure Fields which can produce special types of Chao.
By playing through Action Stages and Subgames, searching through the Adventure Fields or winning Chao Races, players can earn Emblems. In the case of Action Stages, each one has three Emblems, which can be earned by replaying the stages and fulfilling certain objectives, such as beating the level within a time limit. In Sonic Adventure DX, these can unlock hidden extras such as Game Gear games.
The titular protagonist of the game is Sonic the Hedgehog, a hedgehog with the ability to run at supersonic speeds who has returned home after a long journey. His longtime friend is Miles "Tails" Prower, a fox with two tails. Knuckles the Echidna is an echidna with the ability to glide; he is the guardian of the Master Emerald. Amy Rose is a pink hedgehog and views Sonic as her love interest. E-102 Gamma, a gunner robot belonging to the E-100 Series who must pass a test for his superior. Big the Cat is a giant cat interested in fishing and is usually accompanied by his friend, Froggy. The characters are aided by Tikal the Echidna, a mysterious female echidna who appears whenever Sonic, Tails, Knuckles, Amy, E-102 Gamma and Big are sent back in time, and also gives out hints to the player.
The main antagonist is Doctor Eggman, an evil scientist who is planning to use the Chaos Emeralds to destroy Earth. Aiding Eggman is Chaos, a liquified life-form. Chaos was previously sealed by Tikal after her father Pachacamac attempted to steal the Chaos Emeralds from the shrine, but has been freed due to Eggman's actions. Also aiding Eggman is E-100 Alpha (better known as Zero), the first E-series robot constructed as a prototype dispatched to find Amy's friend Birdie. Other characters include the E-Series, who are sent away after Gamma locates the Chaos Emerald. All of them have letters of the Greek alphabet as part of their name. E-101 Beta is a black robot with two gun arms who is later upgraded; E-103 Delta is a blue robot; E-104 Epsilon is an orange robot; and E-105 Zeta is a purple robot who is later turned into a cylinder-like form with several turrets made up of a few Dreamcast machines.
Sonic Adventure is set on Angel Island, an island floating above Earth. The Knuckles Tribe's ruler Pachacamac plans for world domination. His daughter Tikal enters a shrine, discovering the Chaos Emeralds and the Master Emerald, a group of mysterious emeralds with unlimited power. She befriends a peaceful entity known as Chaos, the guardian of the emeralds, as well as the Chao. Despite warnings from Tikal, Pachacamac and the tribe run into the shrine. However, Chaos transforms into Perfect Chaos and destroys the island. Following Chaos' attack, Tikal seals the entity and herself inside the Master Emerald.
Three thousand years later, Knuckles the Echidna guards the Master Emerald on the floating Angel Island when the evil scientist Doctor Eggman sets free Chaos. The Master Emerald is shattered and Angel Island plunges into the sea, causing the Master Emerald's shards and the seven Chaos Emeralds to be scattered. Resolving to search for the shards of the Master Emerald, Knuckles sets off. In Station Square, Sonic the Hedgehog sets off and defeats Chaos after witnessing an attack by the police. Miles "Tails" Prower tests his Chaos Emerald-powered airplane, only to crash on the beach of Emerald Coast. After Sonic rescues Tails, they go to his workshop in the Mystic Ruins, where they are confronted by Eggman. The mad scientist uses Tails' emerald to transform Chaos and he reveals his ultimate plan: with the power harnessed from the Emeralds, Chaos will eventually become invincible and destroy Station Square and Eggman will build Eggmanland (Robotnikland in the international version) over the city's ruins. Sonic and Tails set off searching for emeralds to prevent Eggman from getting them first, but eventually lose the ones they find to Eggman and Chaos. Eggman escapes in his airship, the Egg Carrier, which shoots down Sonic and Tails's pursuing plane.
After Eggman activates E-102 Gamma and fights E-101 Beta during his training, Eggman orders the rest of the E-Series robots to search for Froggy, a frog who has eaten Chaos's tail as well as a Chaos Emerald. Gamma finds Froggy but is chased back to the ship by Froggy's owner Big the Cat. After his crash, Tails finds another emerald and uses it to prepare the Tornado II plane to find Sonic while Sonic lands in Station Square once again. While lamenting her time with Sonic, Amy Rose discovers a Flicky bird and names him Birdie. However, Eggman, having discovered Birdie's location, dispatches his robot Zero to chase the Flicky down. After Sonic turns down an offer to protect Birdie, Zero captures Amy and Birdies and detains them both on Eggman's ship, the Egg Carrier. Sonic and Tails board the Tornado II and infiltrates the Egg Carrier. Knuckles also boards the aircraft after collecting pieces of the Master Emerald and seeing an image of the Egg Carrier in the emerald.
On board the Egg Carrier, Eggman derides the E-Series robots for their failure and removes them before stationing Gamma in Amy's cell. However, Gamma witnesses Beta being rebuilt, Amy convinces him that Gamma should not work for Eggman, as he is an enemy. In a confusion of newly discovered emotions, Gamma releases Amy and Birdie. While being chased by Zero, Amy goes to the ship's deck. Meanwhile, Sonic and Tails confront Eggman, but Gamma is dispatched to attack Sonic. Despite attacking Sonic with lasers, Sonic defeats Gamma, but Amy interferes and has Sonic spare Gamma. Gamma, understanding that Eggman is an enemy, decides to follow the others. The ship loses altitude and Tails, Amy, and Gamma flee, while Sonic restores the ship to its original form. Sonic is confronted by Chaos, who now has six Chaos Emeralds, and defeats it once more before pursuing Eggman. Meanwhile, Knuckles steals back the six Chaos Emeralds and Big uses the Tornado II; they both flee from the ship as it crashes.
After erasing his master registration, Gamma decides to track down his brother robots. After freeing the animals inside the robots, he goes to the Egg Carrier and confronts Beta, in his rebuilt form. Beta uses lasers and missiles to attack Gamma, only to be defeated once more by Gamma. However, the fight also causes Gamma to be destroyed and Birdie's parents are released. Returning to the Egg Carrier, Amy reunites Birdie with its family, but she is confronted by Zero after he knocks down the Flicky. After avoiding contact with Zero's lasers, Amy defeats the robot by using her Piko Piko Hammer and the electrical fences. She sees Birdie and his family off, much to her happiness, and vows to try her best. Tails confronts Eggman. After attempting to destroy Station Square, Eggman resorts to using the Egg Walker to drop bombs on Tails, but is defeated by Tails. Meanwhile, Sonic confronts the scientist in his Egg Viper and destroys it.
A day later, Knuckles restores the shards of the Master Emerald, but Angel Island collapses into the sea once again when Chaos attacks him and Eggman. Chaos absorbs the 6 Chaos Emeralds and locates the seventh aboard the Tornado II, which crashed after Big used it to escape the Egg Carrier. With all the Chaos Emeralds, Chaos transforms into Perfect Chaos, depleting the Chaos Emeralds of their negative energy, and flooding and destroying Station Square. Tikal appears, having taken each main character into the past numerous times beforehand, demanding that Chaos must be sealed back in the Master Emerald. Sonic objects, saying that Chaos's heart would still be filled with anger and sadness if he were to be sealed inside the Master Emerald. Sonic's friends cheer him on, and Sonic uses the Chaos Emeralds' still-present positive energy to become Super Sonic and face off against Perfect Chaos. Following Chaos' defeat, Sonic discovers that the Chao live in Station Square, and leaves them there. United with Tikal, Chaos peacefully departs to the past. The game ends with Sonic chasing after the fleeing Dr. Eggman.
Development of Sonic Adventure began around April 1997 with a development team of 30 members. After developing several titles for the Sega Genesis, producer Yuji Naka worked mainly on the game Nights into Dreams... for the Sega Saturn. Sonic Team started work on an original 3D Sonic title for the Saturn, but development was ultimately shifted to the Dreamcast; according to Naka, remnants of the project can be seen in the compilation Sonic Jam. The development team focused on graphics and high resolution for this game, with Naka reflecting that "[w]e have pushed the Dreamcast as far as we can at present".
Director Takashi Iizuka, having developed Nights into Dreams..., proposed to Naka that they should develop a role-playing video game-style Sonic game. The development team wanted to make a realistic world in the game; however, they never saw environments like ruins or jungles. As a result, the core members of the Sonic Team went to Central America and South America. The team visited Cancun, Guatemala and Peru, and used pictures taken from their journey as "textures in the games." For Tails' sandboarding, the development team used a group of people boarding on sand dunes in Ica, Peru as a reference.
Naka aimed to create levels that would take the player at least five minutes to complete, yet retain similar gameplay to the Mega Drive titles. Following the creation of the basic level maps, Naka wondered "why don't we use this map for other characters?" This led to the introduction of Big and E-102. The development team conducted surveys of fans to ensure that the final product, especially the characters, would please them. Sega made it a top priority to keep the game a secret until shortly before its release. Despite these efforts, screenshots were leaked onto the Internet in mid-1998. Naka presented the game to Edge in mid-August, and official announcement fell on August 22 in Japan.
The soundtrack was provided by Jun Senoue and it contains vocal performances from Tony Harnell, Karen Brake, Marlon Saunders, Dred Foxx, Ted Poley, Nikki Gregoroff and Johnny Gioeli, the latter of whom would later join Senoue to form the band Crush 40. The development team preferred the use of "hot, funky, and rock 'n' roll" music over the traditional techno-based music present in earlier Sonic games. The sound effects were created by Takashi Endo, Tatsuyuki Maeda, Yutaka Minobe and Masaru Setsumaru. The game was first unveiled at the Tokyo Game Show in Tokyo, Japan in October 1998 to a positive response.
In February 1999, Sega's vice president Tadahiko Hirose announced that Sonic Adventure would be released along with Virtua Fighter 3tb and Sega Rally 2 as launch titles for the Dreamcast's international release. In June 1999, Sega announced that Sonic Adventure would be one of the five titles in the Dreamcast's "Masterpiece Collection". The North American version of the game includes Japanese and English-language audio tracks, as well as Japanese, English, Spanish, French and German subtitles. Online gameplay and downloadable content were also added for the localization.
Alternate versions and releases
GameCube and Windows ports
In 2003, an enhanced port was released for the GameCube and Windows titled Sonic Adventure DX: Director's Cut (ソニックアドベンチャー デラックス Sonikku Adobenchā Derakkusu?). Sonic Adventure DX includes a Mission Mode, which included 60 missions to complete throughout the Adventure Fields and Action Stages. It also contains an unlockable compilation that features twelve Game Gear games featuring Sonic and friends. They are Sonic Drift, Sonic Chaos, Sonic the Hedgehog Spinball, Sonic Labyrinth, Dr. Robotnik's Mean Bean Machine, Sonic Triple Trouble, Sonic Drift 2, Tails' Skypatrol, Sonic Blast, Tails Adventure, and the 8-bit versions of Sonic the Hedgehog and Sonic the Hedgehog 2. Also, if all Emblems are collected, then the player can play as Metal Sonic. Reviews were generally less positive than those of its Dreamcast predecessor.
On June 10, 2010, Sega officially announced that Sonic Adventure would be released on both the Xbox Live Arcade and the PlayStation Network in Fall 2010. The Xbox Live Arcade version was released on September 15, 2010, while the PlayStation Network version was released on September 20, 2010. The initial release is based on the PC version of Sonic Adventure DX despite the game simply being called "Sonic Adventure". The DLC package, simply titled "Sonic Adventure DX Upgrade", has launched alongside the game on XBLA, and PSN, which upgrades the game to include all of the features from the GameCube and PC versions with the exception of the Game Gear games and Dreamcast DLC. This version also includes Metal Sonic as an unlockable character.
Sonic Adventure received critical acclaim. The current GameRankings average ranking is 86.51%. It became one of the few Sega All Stars games. The Japanese video game magazine Famitsu gave the game a score of 38/40. Although criticized for its camera system, framerate issues, and fishing stages with Big, the game was still highly praised for retaining the fast and enjoyable gameplay that Sonic was known for in 2D as well as the game's graphics, multiple character storylines, and soundtrack. Brandon Justice of IGN rated the game an 8.6/10, criticizing various glitches and voice acting while praising the game's visuals and gameplay. On the other hand, GamePro gave it a 5/5 saying, "Sonic is fun, fast, and a great reason to purchase a Dreamcast". As of August 2006, Sonic Adventure has sold over 2.5 million units worldwide, making it the best-selling Dreamcast game. This includes one million sold in the United States.
PlayStation Network and Xbox Live Arcade versions
Reviews for the PlayStation Network and Xbox Live Arcade versions of Sonic Adventure were mixed. IGN UK's Arthur Gies gave the Xbox 360 version a score of 3.5/10 and calling it "so fundamentally flawed that it borders on unplayable--the sections that move the fastest, that work best, require the least input from the player." 1UP.com criticized both the game's dated mechanics and the perceived lack of effort put into the port, which "feels like it wasn't even tuned for the Xbox 360 controller." By contrast, Gamer 2.0 claimed that the controls were "slightly more responsive than those of the Dreamcast original," and PlayStation LifeStyle scored it 8/10, complimenting the "frantic, fun gameplay" and "tons of replayability", concluding that "If you manage to overlook the glitches and dinky camera, you'll easily find a gem (or emerald) in this Dreamcast classic."
Promotion and tie-ins
Sonic Adventure received a comic book adaptation courtesy of Archie Comics' Sonic the Hedgehog on-going series. The story arc took place in issues #79-84 and Sonic Super Special #13, originally published from November 1999 to May 2000. This adaptation is notable for its permanent integration of characters and story-lines from the video game into the pre-existing continuity of the comic series, providing explanations for the altered character design for Amy Rose and the history of Station Square hidden beneath Sonic's planet, Mobius. Selected portions of these issues (with the exception of issue #79) were reprinted in Archie's Sonic Super Special Magazine #2 (February 2012).
Franco-American's Sonic the Hedgehog pasta featured Sonic Adventure inspired labeling for a limited time and offered consumers a chance to obtain a free Archie Sonic comic book.
In 2000, Toy Island produced multiple lines of Sonic Adventure toys, featuring 5" action figures, 10" talking figures, and 3" bendy figures. Several of these figures were later reissued as part of their Sonic X lines in 2004.
Following Sonic Adventure, Sonic Team developed the board game Sonic Shuffle for the Dreamcast. After Sonic Shuffle, Sonic Team developed a direct sequel to Sonic Adventure, Sonic Adventure 2, the final Sonic the Hedgehog game for the Dreamcast. Since then, the series has become a multiplatform series.
In 2009, GamePro listed the game as the seventh best platformer of all time, asserting that while it had not aged well in certain respects, its core gameplay "is still some of the best" in the entire series, and its visuals and scope were "hip and cutting-edge" for the time. According to game journalists Rusel DeMaria and Johnny L. Wilson, Sonic Adventure "wasn't a strong enough title" and "failed to catch on with players in nearly the way that Mario 64 had done," "though it had many fascinating features, including the use of the Tamagotchi-like memory card to incubate eggs for little pet creatures" and "some good action segments."
In 2011, Sonic Team developed Sonic Generations, a game that remade aspects of various past games from the franchise. The PlayStation 3, Xbox 360, and PC version contained a remade "Speed Highway" level, and a remade battle with Perfect Chaos. The Nintendo 3DS version contained a remade version of the "Emerald Coast" level.

We were also working on Sonic Adventure--that was originally intended to be out on Saturn, but because Sega as a company was bringing out a new piece of hardware--the Dreamcast--we resorted to switching it over to the Dreamcast, which was the newest hardware at the time. So that's why there wasn't a Sonic game on Saturn. With regards to X-Treme, I'm not really sure on the exact details of why it was cut short, but from looking at how it was going, it wasn't looking very good from my perspective. So I felt relief when I heard it was cancelled."
