Sonic Adventure (ソニックアドベンチャー^?) is a 1999 platform video game developed by Sonic Team and released on December 23, 1998, in Japan by Sega for the Dreamcast. One of its development titles was Sonic RPG (although the final product was an adventure game, not a standard RPG). The final updated edition, known as Sonic Adventure International, was released as a launch title on September 9, 1999, in North America, October 14, 1999, in Europe, October 18, 1999, in Belgium, the Netherlands, and Luxembourg, and December 1, 1999, in Australia. It has sold over 2.5 million copies, making it the best-selling Dreamcast game. It was the first Sonic game on a sixth generation console.

An enhanced port was released in 2003 as Sonic Adventure DX: Director's Cut (see below) for the Nintendo GameCube and in 2004 for Microsoft Windows. The game was ported to Xbox Live Arcade on September 15, 2010 and PlayStation Network on September 20, 2010. The game was featured on Dreamcast Collection, a four-game bundle released in 2011.

Gameplay

Sonic being chased by a giant Orca in Emerald Coast, as seen in Sonic Adventure.

This game is the first in Sonic series to feature free-roaming 3D gameplay. The game is divided into three types of stages: Action Stages, Adventure Fields and Subgames. The division of Action Stages and Adventure Fields was a serious departure from previous Sonic games. In addition, unlike the previous game in the series, Sonic Adventure has six different characters to choose from: Sonic, Tails, Knuckles, Amy, Big and E-102 Gamma; each with their own style of gameplay. Only Sonic is playable at first, but other characters are made available after encountering them in his story. When all stories have been completed, a final story is unlocked.

Sonic's stages involve high speed gameplay, whilst Tails' stages require him to reach the end of the level before Sonic (and in one case, Robotnik) does and Knuckles' stages see him searching the area for shards of the Master Emerald. All three of these returning characters retain a lot of their trademark moves from previous Sonic games. Amy's stages require her to escape from the E-100 Zero robot chasing after her, Gamma's stages involve shooting through levels to reach a target and Big's stages involve fishing for his friend, Froggy.

Action Stages are the main playable levels for each character, where the player must face various enemies in order to complete their respective goals. Adventure Fields split up the action, where players can explore the surroundings to advance the plot, discover new levels or search for items which enhance a character's ability (for example, the Light Speed Shoes allow Sonic to run across a path of rings). Subgames deviate from the main gameplay of the character, which include minigames such as kart racing and snowboarding. Players may also find hidden Chao Gardens, which allow them to raise Chao, a sort of virtual pet. 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. 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.

Synopsis

Characters

Further information: List of Sonic the Hedgehog video game characters

Much of Sonic Adventure centers on Sonic, a hedgehog who has the ability to run at supersonic speeds, and Miles "Tails" Prower, a two-tailed fox who often accompanies Sonic on his adventures; they are the main characters of the game who are in pursuit of Robotnik /DR.Eggman. Supporting characters include Knuckles, an echidna who guards the Master Emerald on Angel Island, Amy Rose, a pink hedgehog who has a crush on Sonic, and newcomers Big the Cat and E-102 Gamma. Big is a purple, noticeably overweight cat who must rescue his best friend Froggy who became possessed by Chaos' tail, and swallows Big's "lucky charm", a Chaos Emerald, which causes him to mutate. Gamma is one among a series of robots designed by Eggman to take orders without question. After an encounter with Amy, he suffers a malfunction and gains a "conscience". He then turns his aim to destroying his robotic brothers and freeing the animals trapped inside them.

The main antagonist of the game is Dr. Robotnik, also known as Dr. Eggman because of his round body shape, who has formulated a new plan to conquer the planet, this time not relying on his robots alone, but employing a strange liquid creature known only as Chaos. Chaos also serves an antagonistic role in the game, and is the guardian of the Chao. He is apparently water or a plasma-like material and changes form after consuming a Chaos Emerald. After consuming all seven Chaos Emeralds, he turns into Perfect Chaos, which Eggman aims to use in order to conquer the planet. The main antagonist of Amy's story is E-100 Alpha (better known as Zero), the first E-100 series robot who is a large green robot and is considered the prototype.^[5] Zero is one of Dr. Eggman's Robots sent to find Amy's friend Birdie. He follows Amy wherever she goes hoping to capture her and the bird. At one point he succeeds but Amy is rescued by E-102 Gamma. Eventually Zero is defeated by Amy on the Egg Carrier.

Dr. Eggman's E-Series of robots play a large role in Gamma's story, as he is one of them, and is out to destroy or "save" the others. 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. He is the first boss in E-102 Gamma's side of the story, and is later upgraded into E-101 Beta Mk II, who is Gamma's fifth and final boss. E-103 Delta is a blue robot who is Gamma's second boss, waiting at the end of Windy Valley. E-104 Epsilon is an orange robot who is the third boss of Gamma's side of the story and is fought at the end of Red Mountain. E-105 Zeta is a purple robot who is Gamma's fourth boss and is located at the end of Hot Shelter. While at first humanoid, Zeta is altered into a cylinder-like form with several turrets made up of a few Dreamcast machines.

Friendly characters who are non-playable include Tikal, a mysterious female echidna who appears whenever Sonic, Tails, Knuckles, Amy, E-102 Gamma and Big are sent back in time. She is trying to stop her father, Pachacamac, from stealing the Chaos Emeralds from the Master Emerald shrine. She appears mostly in the form of a pink ball of light called a Hint Orb. A major feature of the game are Chao, small creatures who can be raised in the Chao Gardens and play a supporting role in the story.

Plot

Centuries ago, the planet was bestowed the seven Chaos Emeralds. These mystical gems were infused with ancient unlimited power, and so it did not take long before wars erupted over who would control them. An eighth much larger emerald, called the Master Emerald, was the controller of the seven Chaos Emeralds, holding the power to either amplify or negate the power within them. Whilst the seven Chaos Emeralds and the Master Emerald rested peacefully, a Chao inhabiting the land nearby the Shrine of the Emeralds accidentally made contact with the holy water surrounding it. The water transcended the Chao into a peaceful creature known as Chaos, who, with the ability to control water, henceforth became the guardian of the Shrine. Some time after, a tribe of Echidnas led by Pachacamac (Tikal's father) angered Chaos by attempting to steal the Chaos Emeralds, ruining the sanctuary Chaos was protecting, and destroying the many Chao living there. Chaos, in his fury, summoned the negative powers of the seven Chaos Emeralds to transform into Perfect Chaos, proceeding to slaughter the Echidna race. Pachacamac's daughter, Tikal, had earlier pleaded with Pachacamac not to disturb the Shrine of the Emeralds, but her efforts were futile. After Perfect Chaos left the shrine to enact revenge on the entire world, Tikal prayed to the Master Emerald to seal her and Chaos within it.

In the present day, Dr. Robotnik learns of the legend surrounding Chaos through a mural in the lost world. Believing it to be true, he creates his flying fortress, the Egg Carrier, seeks out the Master Emerald, and shatters it. This frees Chaos from within the Master Emerald, while also interrupting Knuckles's job of protecting the Master Emerald, forcing Knuckles to collect the shattered pieces in his quest. Without the Master Emerald's power, the originally floating Angel Island (the island on which the 8 emeralds reside) falls into the ocean. Eggman's goal was to control Chaos, using its powers to collect the Chaos Emeralds, destroy Station Square, and build Robotnikland upon its ruins. Eggman created the E-Series robots, a group of powerful robots programmed to obey him, and powered, like all his robots, by animals placed inside them. Soon after, Chaos makes his way into the Mystic Ruins where Big is sleeping. Big's friend, Froggy, ends up swallowing Big's "lucky charm", the yellow Chaos Emerald, and bites off Chaos's tail, causing Froggy to grow his own tail. Big then chases Froggy down in his quest.

Meanwhile, as Sonic returns from an adventure, he sees police trying to attack Chaos, who has arrived in Station Square. Sonic fights and defeats him, but Chaos escapes down a storm drain. Later at night, Eggman creates E-102 Gamma, the second (not including the prototype, ZERO) of his E-Series robots. Eggman tests Gamma's skills by having him do target practice and battle E-101 Beta in order to join the team of the Egg Carrier.

The next morning, Tails tests out a new prototype plane, which malfunctions and crashes. Sonic rescues him, and Tails shows him a Chaos Emerald that he found and was using to power the crashed plane. This Chaos Emerald gets stolen by Dr. Eggman after a battle with him in the Mystic Ruins. Sonic and Tails decide to start searching for Chaos Emeralds so that Eggman cannot use them to empower Chaos. At one point, Eggman takes the light green Emerald from the duo.

Knuckles, busy collecting Master Emerald shards, sees Eggman walk through the hotel with the light green Emerald in his hand. Convinced that it is a shard of the Master Emerald, Knuckles follows Eggman up an elevator. Once up the elevator, Eggman shows that he was actually holding a Chaos Emerald, not a Master Emerald shard. Eggman feeds this Chaos Emerald immediately to Chaos, giving him a total of two. When Knuckles defeats this transformation of Chaos, Dr. Robotnik intentionally misinforms Knuckles that Sonic is also after the pieces of the Master Emerald.

Sonic and Tails, at this point, have 2 Chaos Emeralds left. Knuckles gets into a fight with Sonic over "the Emeralds." In the resulting stalemate, Sonic loses his 2 Chaos Emeralds on the ground. Robotnik feeds the emeralds to Chaos, causing it to transform again. After the three pals defeat Chaos 4, Eggman escapes to his Egg Carrier, Knuckles remains in the Mystic Ruins to take care of "unfinished business," and Sonic and Tails go chase the Egg Carrier in a plane, the Tornado. The pursuit ends badly, with the Egg Carrier blasting off one of the Tornado's wings. Sonic falls into Station Square, whereas Tails falls into the Mystic Ruins Jungle.

Meanwhile, the Egg Carrier flies over Station Square, and a bird smacks into Amy Rose. As soon as Amy picks up and comforts the bird, naming it "Birdie," a robot named ZERO begins to chase her. Amy meets Sonic again, and she drags both of them into Twinkle Park. However, they emerge at different times, having taken different paths through the park.

Meanwhile, Tails has found another Chaos Emerald (which Froggy tried to take away), and he uses to power the new Tornado 2.

Sonic, still in Station Square, sees ZERO, Amy and the bird in claw, walking across the overhead train tracks to the Mystic Ruins. Sonic goes to the Mystic Ruins after them, but once there, finds ZERO and Amy being taken aboard the Egg Carrier. Sonic and Tails chase the Egg Carrier in the Tornado 2. This time, they manage to crash-land on the Egg Carrier. Sonic and Tails explore the Sky Deck, trying to get to the bridge. Once there, they see Amy being interrogated by Robotnik. Robotnik takes the bird, and the bird releases a Chaos Emerald. Robotnik orders E-102 Gamma to deal with the "pests," while he feeds two more Emeralds to Chaos. Chaos now has 6 Emeralds. Gamma, Amy and Tails quickly exit the Egg Carrier, while Sonic deals with Eggman. Sonic defeats Chaos 6, and so does Knuckles, who has now collected all the shards. Sonic, chasing Eggman off the side of the Egg Carrier, lands in the Mystic Ruins Jungle. Eggman, however, lands in Station Square with Tails and Amy. Knuckles lands on Angel Island.

Being desperate, Eggman decides to destroy Station Square through other means: a giant missile. It hits a farther part of Station Square, and does not detonate. Tails, seeing all this, races Eggman to the missile to prevent him from detonating it, and succeeds. Eggman furiously tries to kill Tails with his Egg Walker, and fails. Eggman also tries to kill Sonic with his Egg Viper, and fails equally miserably.

Meanwhile, Knuckles has restored the Master Emerald and Angel Island to the sky, Big has rescued his best friend Froggy, Gamma has rescued his brothers, destroyed by a last resort point blank blast from E-101 Beta MK-II, releasing a bird related to Birdie during the process, and Amy has rescued Birdie and his family from Eggman and ZERO.

However, shortly afterward, Angel Island falls once again, and Eggman is attacked by a surviving Chaos. Meanwhile, noticing that Angel Island has fallen once again, Knuckles attempts to meet with Sonic with the Chaos Emeralds for advice, when suddenly he finds Eggman on the island, bitter and defeated. Knuckles asks him what happened, to which Eggman responds "This is terrible! C-Chaos is...", before being attacked once more alongside Knuckles by Chaos, who steals the latter's six Chaos Emeralds.

Elsewhere, Sonic and Tails take notice that Angel Island has fallen once again, and hurry to the scene, where they find Eggman and Knuckles lying on the ground. Knuckles then reveals to Sonic and Tails that Chaos stole and absorbed the six Chaos Emeralds he was in possession of. Eggman flies off in a hurry, going to his secret hangar to use the Egg Carrier 2. Sonic and Tails then decide that they must retrieve the final Emerald before Chaos, when suddenly, Sonic is teleported to the past where he witnesses former echidna chief Pachacamac and his warriors attacking the Master Emerald shrine, with the chief's daughter Tikal pleading to them not to attack the shrine before they are all killed by Chaos, who absorbs the seven Emeralds and attempts to destroy the world. Sonic then returns to Angel Island, where he and Tails return to Tails's plane the Tornado 2, which uses the seventh emerald as a power source. However, they arrive too late and Chaos retrieves the seventh Emerald before they do.

Meanwhile, in Station Square, Chaos transforms into his final form, Perfect Chaos, and floods the entire city. Sonic arrives, where he witnesses Eggman trying to attack Chaos in the Egg Carrier 2. Chaos immediately destroys it. Tikal then appears, explaining that Chaos's heart is filled with anger and sadness and the negative energy of the Chaos Emeralds flows through him. Chaos drains the Emeralds' power completely, leaving all power of the Emeralds useless. However, Tails, Knuckles, Amy, and Big arrive with all 7 Emeralds and use their collective positive energies along with Sonic's good heart to enable him to re-ignite the Emeralds' positive powers. Sonic transforms into Super Sonic and neutralizes Perfect Chaos. Chaos is not destroyed, but his heart is once again filled with joy and happiness, and also now forgiveness. Tikal takes Chaos back with her, but leaves the Chao to live peacefully with humans. Sonic runs off into Station Square, and Angel Island is put back to its original state high in the heavens.

Development

Development of Sonic Adventure began around April 1997 with a development team of 30 members. Then Sega employee Yuji Naka had been unhappy with prior treatment of Sonic, especially in the Sega Saturn racing game Sonic R^{[citation needed]}. After several titles for the Mega Drive, he worked mainly on the game Nights into Dreams.... However, learning of the Dreamcast brought him a renewed interest in creating Sonic games. 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".^[6]

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.^[6] Sega made it a top priority to keep the game hidden 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.^[6]

Sonic Adventure also introduced a drastic shift in the overall art style of the games that continued to be used over the next few years. The more detailed, modernized redesigns of Amy Rose and Dr. Eggman probably best reflect this. The characters resemble graffiti art in their official artwork, striking more dynamic and extreme poses. In the game, there were some unused items, such as the Sky Dragon from the level Sky Chase, the so-called unused levels, Final Egg and Lost World. The level Speed Highway is going to be included in console versions of the upcoming Sonic Generations and Emerald Coast will be included in the 3DS version. Also, Perfect Chaos will be a boss in the console version of the game.

Music

Head composer Jun Senoue brought a new sound to the Sonic the Hedgehog series with this game, and as such it features many different styles of music such as jazz, rock, techno, pop and country. Each heroic player character (aside from Gamma) also has an instrumental motif that later translates into a vocal theme song that plays during the end credits of their story. The game contains vocal performances from Tony Harnell, Karen Brake, Marlon Saunders, Dread Fox, Ted Poley, Nikki Gregoroff and Johnny Gioeli, whom the latter 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.^[6]

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 デラシクス, Sonikku Adobenchā Derashikusu^?). The Windows version was at first released only in Japan and Europe, but later saw a limited North American release. 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, which comprises twelve Game Gear games featuring Sonic and friends. Also, if all Emblems are collected, then the player can play as Metal Sonic. Also, Cream the Rabbit makes a cameo appearance in certain parts of the game. Reviews were generally less positive than those of its Dreamcast predecessor, scoring more than 20% lower than the original release.^[7]

On June 10, 2010, Sega officially announced Sonic Adventure would be released on both the Xbox Live Arcade and PlayStation Network in Fall 2010. Sonic Adventure DX was released on Steam, as the first in a series of Dreamcast titles to be released as digital downloads. Additional features include enhanced graphics, surround sound, online leaderboards, achievement/trophy support and unlockable Avatar Awards, consisting of a Sonic Adventure T-Shirt and Sonic's "Speed Shoes".^[8]

Sonic Adventure was released on Xbox Live Arcade on September 15, 2010, while the PlayStation Network version was released on September 20, 2010.^[9] The initial release is based on the PC version of Sonic Adventure DX despite the game simply being called "Sonic Adventure".^[10] The DLC package, simply titled "Sonic Adventure DX Upgrade", has launched alongside the game on XBLA, for 400 Microsoft Points, and $4.99 on PSN, effectively making the entire Sonic Adventure DX 1200 Microsoft points ($15). It 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.

Reception

The reception at the time of original Dreamcast version was overwhelmingly positive, including reviews from GameSpot and GameSpy being above 90%. The current Game Rankings average ranking is 88%.^[11] It became one of the few Sega All Stars games. In Japan, it received an excellent 38 out of 40 from Famitsu.^[12] 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.^[13] On the other hand, GamePro gave it a 5/5 saying, "Sonic is fun, fast, and a great reason to purchase a Dreamcast". The game has sold over 2.5 million copies worldwide, making it the best-selling Dreamcast game.^[14] This includes one million sold in the United States.^[15]

The GameCube version received less positive reviews, IGN gave the DX version a 5/10 criticizing the game's glitches, poor framerate, and clunky camera making it less fun to play in contrast to its original Dreamcast version but praised the overall presentation of the game.

The PlayStation 3 and Xbox 360 ports received even less favorable reviews. While some critics viewed it as a good piece of nostalgia, others criticized the lack of improvements and the game's more noticeable age, with IGN giving it a score of 3.5 out of 10, calling it "so fundamentally flawed that it borders on unplayable", making it the lowest scored Sonic game on the site since Sonic and the Black Knight.^[16] 1UP.com gave it a D rank, criticizing its lack of improvements and touchy controls.^[10] Retro Gamer gave the Xbox 360 port 63%.
