What kind of hedgehog are you?


— Tagline

Sonic Adventure 2 (ソニックアドベンチャー2 Sonikku Adobenchā Tsū?) is a platforming video game in the Sonic the Hedgehog series published by Sega for the Dreamcast. It is the sequel to Sonic Adventure, released in June 2001 to celebrate the 10th anniversary of the franchise. This was the final title in the series to be released on a Sega console before the company transitioned to a third party developer. Sonic Adventure 2 is notable for serving as the debut of Shadow the Hedgehog, a black hedgehog that resembles Sonic the Hedgehog with similar powers, and Rouge the Bat, an enigmatic treasure hunter.

Adventure 2 was built around the dichotomy of "good and evil" featuring Hero and Dark storylines. In the Hero story, Sonic is framed as an escapee and teams up with Tails, Knuckles, and Amy to stop Doctor Eggman, who plans to subdue the world with the Eclipse Cannon, a superweapon stored at the Space Colony ARK. The Dark story, conversely, features Eggman as he attempts to conquer the world using the same weapon with Shadow and Rouge's help. The game carries on its predecessor's gameplay but introduces three distinct styles for its six playable characters: Sonic and Shadow focus on high-speed platforming, Tails and Eggman on shoot 'em up sequences, and Knuckles and Rouge on treasure hunting. The Chao system from the first game is expanded, allowing players to raise Hero and Dark Chao as a reflection of the game's central theme.

Development for Adventure 2 began in September 1999, shortly after the international release of its predecessor. It was developed by Sonic Team USA (later Sega Studio USA), an American branch of Sonic Team established to ensure stricter management over the series' image in Western markets. Its visuals were inspired by those of California, where the team was headquartered, to give a more "American atmosphere" than its predecessor.

Upon release, Sonic Adventure 2 received positive reviews for its gameplay variety, visuals, and music, but faced criticism for unresolved issues from its predecessor, particularly with camera controls. Due to being released at the end of the Dreamcast's lifetime, it only sold around 500,000 copies. The game was re-released for the Nintendo GameCube in late 2001 and early 2002 as Sonic Adventure 2: Battle, with various updates to the graphics and gameplay features.

Plot[]

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

Storylines[]

Fifty years ago, Professor Gerald Robotnik, the grandfather of Doctor Eggman, directed a top-secret military initiative known as Project Shadow to achieve immortality. The project, conducted on the Space Colony ARK, resulted in two creations: a prototype, the Biolizard, and Shadow the Hedgehog. However, doubts over the project's safety resulted in the ARK being raided by Guardian Units of Nations (G.U.N.) military forces. The raid resulted in the deaths of everyone involved in Project Shadow, except Gerald, who was imprisoned, and Shadow, who was ejected back to Earth.[3] Driven insane by the death of his granddaughter Maria during the raid, Gerald implanted false memories into Shadow to make him seek world destruction; Gerald was executed shortly after, while Shadow was held in stasis on Prison Island.

Sonic Adventure 2 begins after Dr. Eggman learns of Project Shadow, intending to exploit Gerald's research to conquer the world.[4] The game's plot is divided into two storylines, Hero and Dark. Both happen concurrently, though the Dark story begins slightly earlier. Completing both stories unlocks a final storyline.

Hero Story[]

Talk about low budget flights! No food or movies? I'm outta here! I like running better!


— Sonic after fleeing from capture

Sonic fleeing from the GUN Military Truck in the city.

Sonic the Hedgehog is falsely accused by G.U.N. of deserting from Prison Island and is taken aboard a military helicopter en route to the island.[5] While flying over Central City, Sonic breaks free and rushes through the city to flee persecution. That night, he encounters Shadow the Hedgehog, who resembles him in speed and appearance. Deducing that he has been mistaken for Shadow, Sonic attempts to attack but Shadow uses his green Chaos Emerald to warp away through Chaos Control, leaving Sonic to be re-captured by G.U.N.

The next day, in a desert, Knuckles the Echidna and Rouge the Bat are fighting for possession of the Master Emerald when it is stolen by Doctor Eggman. Knuckles shatters it into pieces, and he and Rouge start to hunt for the missing shards separately. Knuckles finds several shards in Wild Canyon, Pumpkin Hill and Aquatic Mine.

Meanwhile, Miles "Tails" Prower storms Prison Island to liberate Sonic. On his way, he finds Eggman attacking Amy Rose, who has come here for the same reason. Tails and Eggman have a fight that results in a stalemate, while Sonic is freed by Amy and flees into the jungle on Prison Island. There, he encounters Shadow and learns that the island is about to explode due to Shadow and Eggman planting bombs all over it. Sonic rushes to reunite with his friends, and they escape just before Prison Island is destroyed.

As Sonic's group returns to Central City, Eggman makes a global broadcast threatening to blackmail the world into submission. He demonstrates his power by using the Eclipse Cannon, a superweapon on the Space Colony ARK, to destroy part of the Moon. The heroes deduce that Eggman has most of the Chaos Emeralds and plan to track down his location with Tails' Emerald. As they escape persecution from G.U.N., Sonic and Tails infiltrate the limousine of the president of the United Federation and hack its computer, learning that Eggman is headquartered on the ARK. Concurrently, they meet Knuckles, who guides them to the desert where the doctor's Hidden Base is found. There, they are confronted by Eggman but manage to man a rocket to the ARK.

As Knuckles splits from the group to retrieve the Master Emerald's shards, which have drifted into space, Sonic and his group hatch a plan to sabotage Eggman's scheme by giving him a fake Chaos Emerald which would shut down the Eclipse Cannon. As Sonic rushes to insert it into the cannon however, Amy is held at gunpoint by Eggman, forcing Sonic and Tails to focus on saving her instead. The heroes' plan backfires when Tails accidentally reveals that the Emerald they have is a decoy, and Eggman ejects Sonic into space with an exploding pod. However, Sonic survives when he uses the fake Emerald to replicate Shadow's Chaos Control, and reunites with Knuckles. He eventually confronts Shadow and defeats him, disabling the Eclipse Cannon as well.

Dark Story[]

By accident, I found my grandfather's diary. In it, he described a mysterious top-secret weapon he was working on called "Project Shadow". The diary looked like it was sealed inside the military research facility when it was shut down over 50 years ago. What a waste of good research! [...] I might as well get some use out of it!


Doctor Eggman at the beginning of the Dark story[4]

Doctor Eggman releasing Shadow the Hedgehog.

Doctor Eggman breaks into Prison Island and releases Shadow the Hedgehog, the end result of Project Shadow. In gratitude, Shadow offers his servitude to the doctor, commands him to bring Chaos Emeralds, and tells him that they will reunite on the Space Colony ARK. As he returns to his Hidden Base in the desert, he finds Rouge the Bat and Knuckles the Echidna fighting over the Master Emerald, but his attempts to steal it end in vain after Knuckles shatters it, prompting Rouge and Knuckles to hunt for the shards separately.

That night, Shadow, who has been mistaken for Sonic, has stolen a Chaos Emerald in Central City. Having been brainwashed into thinking he promised Maria revenge, he ventures through the city, fleeing from military forces, and encounters Sonic, whose attempts to attack him are rendered ineffective through Shadow's Chaos Control. Eggman meets with Shadow on the ARK as they had planned, and Shadow tells him of the Eclipse Cannon, a superweapon capable of destroying an entire planet when powered by the Chaos Emeralds. The doctor hatches a plan to power the cannon and use it to submit the world to his rule. Rouge, who has infiltrated the ARK through a transporter in the Hidden Base, joins them after handing over a Chaos Emerald.

The next day, the three return to Prison Island, planning to steal the three Chaos Emeralds there and explode the island. Despite several setbacks from Sonic and his friends, the operation is a success. With six Emeralds, Eggman makes an ultimatum to the world: surrender within 24 hours, or he will use the Eclipse Cannon—whose power he demonstrates by destroying part of the Moon—to annihilate the planet. However, negotiations with the United Federation are foiled by Sonic. The trio learns that Tails is in possession of the seventh Chaos Emerald and return to Earth to find him. As Tails and his friends infiltrate the Hidden Base, Eggman dispatches the Egg Golem to thwart them, but Sonic ultimately makes the robot malfunction and attack the doctor, giving the heroes enough time to board a nearby space rocket and head to the ARK. Eggman later tracks down two separate readings from the Chaos Emeralds. Deducing that Sonic's friends are planning to trick him with a decoy, the doctor returns to the colony to face them.

In-game screenshot of the final cutscene of the Dark Story, which is set on the ARK, depicting Eggman maniacally laughing in front of a large pillar with the seven Chaos Emeralds installed.

Eggman finds Amy Rose stranded on the ARK and uses her as bait to lure Sonic and Tails to him. He fools Tails into revealing that Sonic is carrying the fake Chaos Emerald, and ejects Sonic into space with an exploding pod. With Sonic presumed dead, Eggman fights Tails but is ultimately defeated. Meanwhile, Rouge uncovers details of Project Shadow, and questions Shadow over his identity. Shadow maintains that he will fullfil his promise to Maria as the real Shadow. He then confronts Sonic again in a race towards the Eclipse Cannon. At that time, Eggman sneaks off with the true seventh Chaos Emerald, which he triumphantly installs into the Eclipse Cannon.

Last Story[]

This is a death sentence for every human being on Earth. If my calculations are correct, the Space Colony ARK will impact the Earth in twenty-seven minutes and fifty-three seconds. All of you will be destroyed, along with your beloved planet Earth.


Gerald Robotnik's last message, broadcast by Eggman initiating his doomsday program

Eggman upon unknowingly activating Gerald Robotnik's doomsday protocol.

Doctor Eggman's joy over having installed the seven Chaos Emeralds into the Eclipse Cannon is short-lived; instead of the cannon firing, a loud alarm blares and images of Gerald Robotnik appear across the Space Colony ARK. Sonic, Tails, Knuckles, Amy, Shadow, and Rouge learn that the ARK is approaching Earth at terminal velocity, threatening to annihilate the planet. Suddenly, a video filmed by Gerald prior to his execution is broadcast out to the whole world. In it, Gerald explains his fail-safe program to destroy the world, which was activated when Eggman inserted the Chaos Emeralds into the Eclipse Cannon.

Sonic and the others encounter Eggman, who hands Rouge a hard drive of Gerald's diary following the shutdown of Project Shadow. It reveals that Gerald's insanity over Maria Robotnik's death led him to brainwash Shadow's mind to seek destruction, warning that freeing him will lead to catastrophic consequences. Eggman explains that the energy from the Chaos Emeralds was enough to overcharge the Eclipse Cannon, making the core highly reactive and unstable; to prevent the ARK from crashing into Earth, the group must stop the energy flow. They hatch a plan to use the Master Emerald to neutralize the energy of the Chaos Emeralds, and everybody but Amy and Shadow rush to the Cannon's Core. Initially indifferent, Shadow is persuaded by Amy's plea that most people do not deserve to die. This rekindles his true promise to Maria—to give humanity a chance for happiness—and he joins the others.

— Shadow after helping save the world

Sonic's group enters the Cannon's Core, designed after the Altar of Emerald, but they encounter the Biolizard. Shadow defeats the creature as Knuckles uses the Master Emerald to neutralize the Chaos Emeralds. However, the Biolizard uses Chaos Control to fuse with the ARK, becoming the Finalhazard and keeping the colony on its collision course. Sonic and Shadow use the Chaos Emeralds to become Super Sonic and Super Shadow respectively. After a final showdown, they defeat the Finalhazard and use Chaos Control to warp the ARK back into orbit before it hits Earth. However, Shadow, unable to maintain his transformation, plummets back to Earth, content that he fulfilled his promise to Maria, culminating in his apparent death. As humanity celebrates, those on the ARK reflect on their recent adventure. Sonic returns to Earth, uttering "Sayonara, Shadow the Hedgehog"[note 1] as the credits roll.

Gameplay[]

As with its predecessor, Sonic Adventure 2 is a 3D third-person action platformer video game. Gameplay takes place between two different points of view storylines, the "Hero" story and the "Dark" story; the player has the option of advancing in either one or the other at any time. The player controls Sonic, Knuckles and Tails in the Hero side of the story, while they play as Shadow, Rouge and Dr. Eggman in the Dark storyline. The characters all play similarly to their opposite counterparts. The game is divided into a series of stages where the player controls one of the aforementioned characters, depending which story they are in. Interspersed between the levels are various bosses, which one particular character must fight. Levels advance in order for each storyline, and come between each of the playable characters. The main story line can only be finished when both Hero and Dark story modes are finished, and an extra story feature is revealed where the player must use almost every characters to beat it.

Similar to past Sonic games, the goal of Sonic Adventure 2 is to get to the end of the aforementioned stages while a timer counts the time spent within each stage, though each character has a different way of passing through them. In these stages, the player might find Rings, which serve as their character's main defense against enemies and obstacles; should the playable character be hit by an obstacle or enemy, they will survive at the cost of losing all their Rings. However, if the player takes damage without having any Rings on them, they will lose a life, or get a Game Over if they do not have any lives left. In the former's case, the playable character will respawn at the latest Point Marker they touched, or at the start of the stage if they did not touch any Point Markers. In addition, there are certain circumstances where the character will be given an instant death, no matter how many Rings they have. These include drowning, being crushed, or falling into a bottomless pit. Also, when passing a Point Marker, the player receives a specific power-up based on the number of Rings they are holding:

At the end of each stage, the player is given a score based on the number of Rings collected and time spent within the level. The less time is taken and the more Rings obtained, the higher the score is. A first for the series, the player is also given a Rank based on their performance, a letter grade that is either A, B, C, D, or E, with A being the highest and E being the lowest. Irrelevant to any other factors, an A-Rank is automatically awarded to players that complete any score-ranked mission with all of the Rings from that level in the player's possession.

There are five missions within each Action Stage; in order to obtain the second mission, the player must complete the first one, to unlock the third, the second mission must be finished, and so on. In order from first through fifth, the missions are: to complete the level, collect one hundred Rings, find a "lost Chao" using the Mystic Melody Level Up Item, finish within a time limit, and complete a "Hard mode" version of the stage.

Emblems are also given within the game, and there are one-hundred and eighty Emblems in total. In order to gain all Emblems, players must complete every mission within every stage, achieve an A rank in all stages and missions, etc. After collecting all Emblems, the player unlocks Green Hill, a remake of Green Hill Zone from the original Sonic the Hedgehog.

Returning from Sonic Adventure are the Chao, small creatures that can be raised by the player in Chao Gardens, similar to a virtual pet. A new feature introduced is that Chao may change their appearance and alignment depending on what character the player is using and how do they treat them. If a Chao is well treated by a Hero side character or abused by a Dark side one, they will turn into a "Hero Chao," a benevolent and polite Chao. On the other side, well treated by a Dark side character or abused by a Hero side one, they will turn into a "Dark Chao," a rude type of Chao.

Character-specific gameplay[]

High-Speed Action Stages[]

Sonic and Shadow's gameplay styles are identical to that of the former in Sonic Adventure. The fastest of their respective character rosters, they can perform a Spin Dash to gain instant speed in seconds and use a Homing Attack to target an obstacle or enemy and home in on them for an attack. Sonic and Shadow's stages end by touching a Goal Ring.

In addition, Sonic and Shadow's abilities can be upgraded by collecting Level Up Items; after finding the Light Speed Shoes or the Air Shoes, respectively, they will be able to perform the Light Speed Dash; when they obtain the Ancient Light, they will be able to perform the Light Speed Attack; and by getting the Flame Ring, Sonic and Shadow will be able to use the Fire Somersault.

Lock-On Shooting Stages[]

Tails and Dr. Eggman have similar gameplay styles to that of E-102 Gamma in Sonic Adventure. In gameplay, they are driving the walker mode of the Cyclone and the Eggwalker, respectively. Unlike other characters, Tails and Eggman make use of a Health Gauge, which can be filled by collecting rings. When the Health Gauge is empty, the player will lose a life, or get a Game Over if they run out of lives. Despite walking slowly and being capable of doing small jumps, they can use the Lock-on to target enemies and obstacles, and the Lock-On Missile to launch missiles to said targets. The Volkan Cannon fires a mini-gun at targets, but is not as effective as the Lock-On Missile.

Tails and Eggman's abilities can be upgraded by collecting Level Up Items; when they find the Bazooka or the Large Cannon, respectively, they will be increase the power of the Volkan Cannon; by collecting the Booster or the Jet Engine, respectively, the playable character will be able to Hover; and the Laser Blaster makes the missiles of the Lock-On Missile release violent explosions upon contact, thus damaging enemies that are near the target as well. Eggman can also collect the Protective Armor, which increases the durability of his Eggwalker.

Hunting Stages[]

Knuckles and Rouge have the same gameplay styles as Knuckles in Sonic Adventure. When playing as either of them, the player is required to find three Master Emerald shards or similar objects hidden in the stage to complete it. To facilitate the search of the shards, the player will be able to make use of the Emerald Radar, which will tell them whether or not they are near a hidden object. While slightly slower than Sonic and Shadow, they are able to glide to fall much slower to the ground, thus being able to pass over large pits. If they hit a vertical wall while gliding, Knuckles and Rouge will climb, where they will be able to climb or scale said wall. They can also dig when they are on a solid ground, and thus be able to find buried objects.

Other stages[]

Bosses[]

In Story Mode, there are several bosses that the player has to fight after completing certain stages. There may also be times where two bosses are separately fought in a row following a stage.

Modes[]

1P Play[]

Story[]

Story is where the player follows along with the plot of the game. There are two stories at first: Hero and Dark. Once these two are completed, a third, final storyline known as "Last" is unlocked. Progressing through this mode unlocks more stages to play in Stage Select. Also, every time the player leaves the game and comes back to this mode to where they left, a short summary of one of the playable characters is played so that they can remember where they left of. When a story is finished, the player unlocks its "Boss" mode and is able to revisit certain points of the plot.

Stage Select[]

Stage Select is the overall map of the game's settings. Here they can play any stages they have already completed in Story mode. Each of these levels has five separate missions:

  • Mission 1: This is the mission that is played in Story mode, where the player must simply get to the ending of the stage or, in Hunting Stages, find the three hidden items. Ranking is given based on score.
  • Mission 2 (Collect 100 Rings!): In this mission, the player has to collect one hundred Rings to succeed. Ranking is given based on time.
Sonic Adventure 2 lost Chao

Sonic having found the lost Neutral Chao in Pyramid Cave.

  • Mission 3 (Find the lost Chao!): Here, the player is tasked with finding a Neutral Chao that is hidden somewhere in the stage. Most of the time this Chao is found in an area that is only accessible by interacting with an Ancient Ruin, meaning that the Mystic Melody has to have been obtained beforehand to complete this mission. Ranking is given based on time.
  • Mission 4 (Finish the stage in [time]!): The player has to reach the end of the stage under a time limit. Worth noting is that there are no Star Posts in these missions, meaning that they will have to start from the beginning once they lose a life. If the player runs out of time, they will be taken back to the beginning of the stage, but they will not lose a life. Ranking is given based on score.
Sonic Adventure 2 Hard mode comparison

Comparison of an area in City Escape normally (left) and in Hard mode (right); the path through the staircase has been sealed off; the right side has fewer platforms, the Super Ring Item Box has been removed, and a Gun Wing has been added instead.

  • Mission 5 (Clear Hard Mode!): This mission is unique from the others since the player has to finish a much harder version of the stage. Various paths are now sealed off, tougher enemies are more prominent, there are fewer platforms over bottomless pits, enemies sometimes appear out of nowhere, and the player is forced to have already obtained certain Level Up Items to progress. Ancient Ruins now simply spawn 1-Ups or are removed sometimes. In Hunting stages, the three items the player must find are always in the same spot. Ranking is given based on score.

Missions are unlocked once the player beats the one prior; for example, Mission 4 is accessible after beating Mission 3, which is unlocked after beating Mission 2. Completing a mission for the first time awards the player an emblem.

Kart Race[]

Kart Race is racing mode that is unlocked after beating either Route 101 in the Hero story or Route 280 in the Dark story and plays the same as these two stages. Each of the six playable characters has their own karts.

Boss[]

Boss is unlocked after beating either the Hero or Dark story. Here the player goes through all of the chosen story's bosses in order, similar to the Boss Sub Game from Sonic Adventure. After beating all of the bosses, the player is awarded an emblem.

2P Play[]

Downtown Race

Sonic and Shadow racing through City Escape.

Unlike its predecessor, Sonic Adventure 2 has a multiplayer mode. 2P Play features four different modes: Race[13] (Sonic/Shadow stages), Shooting[13] (Tails/Eggman stages), Hunting[13] (Knuckles/Rouge stages), and Random.[13] Each type of stage is played split-screen, except for the shooting stages. The conditions for winning in each type are as follows:

  • Race: The player who reaches the Goal Ring first wins.
  • Hunting: The first player to find the given amount of Master Emerald shards wins.
  • Shooting: The first player to reduce their opponent's HP Gauge to zero wins.

There is also a Kart Racing mini-game in 2P Play mode, but the player will have to clear the Kart stages in the Hero and Dark stories in order to enable it.

In the 1990s, Sega was amongst the main competitors in the video game market and was able to gain a foothold against Nintendo with the release of Sonic the Hedgehog in 1991 for the Sega Genesis/Mega Drive to directly compete against the Super Mario franchise on the Super Nintendo Entertainment System. In spite of an eventual fierce rivalry between the companies specifically in North America, the game became a massive success for Sega, and quickly spanned a multimedia franchise with video games, cartoons, and comics; in just two years, the eponymous character had gone from being a sketch to being a character more widely recognized by American children than Mickey Mouse like Mario.[16] However, in the later years of the decade, Sega began to lose its dominance with the start of the 32-bit era, where its Saturn system was overshadowed by the Nintendo 64 and Sony's PlayStation. In a last-ditch effort, Sega released the Dreamcast in 1998 in Japan and 1999 in the rest of the world. It was a new console far more powerful than its competitors with new features like online gaming.[17] Sonic Adventure was one of the release games, and received critical acclaim. However, the Dreamcast ultimately failed against its competitors.

Sonic Adventure was developed by Sonic Team in Japan and was initially released in that country on 23 December 1998.[18] In 1999, several of its members, including Takashi Iizuka and series co-creator Yuji Naka, moved to the United States to develop a Western localization of the game, since the Dreamcast had not yet been released outside of Japanese markets. The team members established Sonic Team USA (later Sega Studio USA) as a US-based division of the group. The subdivision was established so that Sonic Team could have a stricter management over the series' image outside of Japan, since they felt that the comics and television shows that had been produced in North America were off-brand for the series and made Sonic "feel like a completely different character".[19][20]

The localized version of Sonic Adventure was released in mid-to-late 1999. Shortly afterwards, Sega demanded a sequel, and work on a new game began soon afterwards. In some ways, this has been compared to Sonic the Hedgehog 2, which was developed by the Sega Technical Institute in the United States, compared to the first game which had been made in Japan. Development for Sonic Adventure 2 began shortly after the American release of the international version of Sonic Adventure in September 1999.[21] Iizuka served as director and art designer, while Naka was the producer.[22]

Gameplay[]

The first thing the developers did when it came to the gameplay was to recreate Sonic Adventure's structure but making it more dynamic by focusing more on the action. Wanting to go back to the series' roots, the team removed the Adventure Fields from the first game to make the level succession more streamlined. Also, whereas Sonic Adventure featured a mix of action, exploration, etc., for Sonic Adventure 2, the developers separated these sequences according to each character's gameplay.[21]

The development team sought to make the game an impressive experience, and made it run at 60 frames per second with "tempo", giving Sonic a variety of actions rather than focusing on speed alone.[21] Its levels facilitated this flow, making Sonic seem faster than he was.[23] Developing the game was also much easier than Sonic Adventure due to the team's experience with the Dreamcast's hardware.[24] The game would end up having six different playable characters, all of whom were given roughly equal gameplay time, unlike Sonic Adventure where Sonic's story was much longer than the others.[23]

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.[23] In Sonic Adventure 2, Chao have the ability to socialize, so they resemble a "real artificial life form."[24]

The developers of Sonic Adventure 2 used San Francisco, where they were located, as an inspiration for the artstyle of the game. This inspiration is most noticeably in the Hero story's first level, City Escape (pictured).

Since Sonic Team USA is located near San Francisco and its Bay Area, we discovered some magnificent locations. We decided to insert the beauty of these settings into our game.

Whereas Sonic Adventure was inspired by Sonic Team's trip through Latin America, the developers sought to give Sonic Adventure 2 an "American atmosphere".[23] They were influenced by San Francisco and other locations in the United States, such as Yosemite National Park (where they vacationed during its development), the Golden Gate Bridge, and the San Francisco Bay Area.[21]

Characters[]

During the development of Sonic Adventure, the team wanted to introduce a new rival for Sonic in a potential sequel, but rarely discussed the idea. The developers eventually found use in this new character when they laid out the "good vs. evil" storyline.[25] The character was co-created by Iizuka and the writer of the story in Sonic Adventure 2, Shiro Maekawa.[26] The rival character's name was originally "Terios" ("reflection of"), a reference to being Sonic's doppelganger,[27] before being changed to Shadow the Hedgehog.

Maekawa was tasked with developing Shadow, whom they wanted to look just as "cool" as Sonic. Maekawa settled on the design of a black hedgehog, but struggled coming up with his personality. One night, while he was brainstorming lines for a scene in which Sonic confronts Shadow for impersonating him, Maekawa came up with Shadow's first line: "Hmph, aren't you the fake one here?" To further shape his "subtle" character, Maekawa envisioned Shadow would refer to himself with the more humble Japanese pronoun boku (?).[26]

Another character, Rouge the Bat, was created to contrast Knuckles. Funnily enough, her original name was "Shadow", before being changed to the current one.[28]

Sega announced a follow-up to Sonic Adventure and a spin-off, which would become Sonic Shuffle, on 4 October 1999.[29] The newly named Sonic Adventure 2 appeared for the first time at E3 on 11 May 2000,[30] with Sonic Team adding the video shown to its website on June 30.[31] Sonic Team posted a trailer and a number of screenshots on 30 May 2001,[32] with Sega promoting Sonic Adventure 2 as the last Sonic game for the Dreamcast and as a celebration of the series' tenth anniversary.[33] Sega held a tenth anniversary party for Sonic in June 2001, at which attendees could compete in a battle tournament, and the winner played against Takashi Iizuka himself.[24]

Sonic Adventure 2 was released worldwide on 23 June 2001,[34] marking the Sonic series' tenth anniversary. A special collector's edition of the game was produced, featuring a large blue case that contained the game, a music CD (featuring tracks spanning Sonic's ten year history), a Sonic the Hedgehog retrospective booklet and a commemorative coin.

Pre-release[]

A demo version of Sonic Adventure 2, titled Sonic Adventure 2: The Trial, was distributed as a bonus to those who purchased the first copies of Phantasy Star Online.[35][36] Since Phantasy Star Online was released in late 2000 in Japan and early 2001 in Western regions, this bonus disc served as an excitement builder for the final release of the game just six months later. This version only included one stage (City Escape) and a rudimentary two-player mode accessible through hacks.

While there are many changes between Sonic Adventure 2: The Trial and the final version of Sonic Adventure 2, a key difference is that Sonic is lacking the Grind Shoes in the demo, as Sega's partnership with Soap was made late in the game's development.

Sonic Adventure 2 is known for its infamous commercial which shows a scientist approaching a hedgehog labeled "Good Hedgehog" and petting it. The camera then goes to a tank labeled "Bad Hedgehog" where a cow is being lowered in. Eating sounds could be heard along with screams from the cow until the screen goes back to the "Bad Hedgehog" burping, this being a parody of a scene from Jurassic Park.

Soundtrack[]

Like its predecessor, Sonic Adventure 2 received critical acclaim, with scores of 89% and 83.3% from review aggregators Metacritic and GameRankings, respectively.[37][38] 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.[39][41] Johnny Liu of Game Revolution praised its replay value of multiple playing styles and 180 different goals.[42] 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."[46]

Shahed Ahmed of GameSpot criticized Adventure 2's camera for the "cardinal sin" of 3D platformers, as it forces the 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.[43] According to Chau and Liu, camera issues were absent in Tails and Dr. Eggman's levels and insignificant in Sonic and Shadow's, but searching for Emerald Shards and items in cramped sections of Knuckles and Rouge's levels was frustrating.[42][46] Edge found camera problems permeating the game, with no significant improvement from Sonic Adventure.[39]

Liu called the graphics "sweet, sweet eye-crack".[42] Four-Eyed Dragon wrote that the game "is simply jaw-dropping beautiful," citing its detailed backgrounds and scenery and the playable characters' and enemies' extensive color palettes.[41] According to Chau, the game had "some of the best textures ever seen" and was one of the most beautiful Dreamcast games.[46] Edge was impressed by the texture detail and draw distance,[39] and Chau, Liu, and Ahmed praised its 60-frame-per-second rendering speed.[42][43][46]

According to Ahmed, the game's music was a step up from Sonic Adventure's "campy glam-rock and J-pop soundtrack," with less emphasis on lyrics,[43] and Liu appreciated its more "understated" approach.[42] Four-Eyed Dragon praised Sonic Adventure 2's music as "an eclectic mix of orchestrated masterpieces, guitar tunes, and melodic hip-hop voices gracefully fill the game's ambiance to a perfect pitch."[41] Reaction to the voice acting was mixed; although Ahmed said "The voice acting, and the lip-synching in particular, is executed quite well,"[43] Liu and Chau thought the English voices were inferior to the Japanese ones.[42][46]

Ahmed criticized Sonic 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.[43] Although Liu agreed that despite the game's ambitious scope and themes it failed to advance the series' core plot beyond the original Sega Genesis/Mega Drive Sonic games,[42] Edge appreciated the story's presentation from both perspectives: hero and villain.[39]

Sonic Adventure 2 received several accolades, including the 2001 IGN's Editors' Choice Award.[53] ScrewAttack called it the fifth-best Dreamcast game,[54] and GamesRadar rated it the tenth greatest Dreamcast game out of 25, saying: "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."[55] In February 2014, IGN's Luke Karmali called the game his tenth-favorite game of all time.[56] Sonic Adventure 2 was placed at the number one spot in WatchMojo's "Every 3D Sonic Game Ranked" video; it was also placed at the #4 spot in their "Top 20 Sonic the Hedgehog Games" list.[57]

Re-releases[]

Adaptations[]

The Sonic X anime series included a six-episode adaptation of the game's events between "Project: Shadow" and "Showdown in Space", known as the Shadow Saga. Like its predecessor, the adaptation was mostly faithful to the game's plot, with the Japanese version even being a word-for-word adaptation at some points. However, parts were written in for characters that did not originally appear in Sonic Adventure 2 such as Christopher Thorndyke and Cream the Rabbit.

In Sonic the Hedgehog #98, published by Archie Comics, a two-part adaption of Sonic Adventure 2 was presented, written by Karl Bollers and Ken Penders.

The Sonic the Hedgehog 3 film produced by Paramount Pictures will be heavily inspired by elements of the game itself.

Trivia[]

  • This is the first Sonic game to have swearing in the English track. Swear words can be heard in the lyrics of the main theme of Knuckles the Echidna and in the lyrics for the background music of some of the stages he goes through (i.e., "Deeper"). This was also the main reason why the GameCube version has a "Lyrics" warning on the ESRB rating.
  • Sonic Adventure 2 is the only game where Sonic wears the Grind Shoes in order to promote the Soap product which the Grind Shoes were based on, along with the new extreme sport, freestyle grinding, that the shoes were made for. There are also many billboards, blimps, and benches in the game that advertised the shoes. The Grind Shoes themselves are a custom version of the Scorcher/Nitro Soap Shoe, while Shadow wears a pair of custom Broadside Soap shoes, as grinding (or "soaping") debuted as an important new gameplay element.
  • If one were to go to the Theme Select in the Options menu and rotate the Control Stick clockwise for a few moments until hearing a chime sound, they would then see a picture of the President's Secretary and will then be able to select the Secretary's menu theme.
  • Like Sonic Adventure, in the original Dreamcast version of the game if you insert the disk into a PC, special wallpapers will be available to download as an easter egg. As well as that, there is a list of main series Sonic games prior to Sonic Adventure 2, although Sonic the Hedgehog CD is absent from the list.
  • The camera can be used to move objects in the game. This is most noticeable in the Chao Garden if the player has a fruit in front of the camera and they walk away from it. The same thing can be done in the Chao Garden in Sonic Adventure.
  • In the first cutscene of the demo version, before the player enters City Escape, the man on the radio says, "What the hell?" in the text. In the final release, the script instead says, "What?!"
  • Sonic features the most Level Up Items out of the playable characters in Sonic Adventure 2, with a maximum of six. Knuckles and Eggman have five Level Up Items, and Tails, Shadow, and Rouge have a minimum of four.
  • For unknown reasons, in the game's files, there is an unused voice clips of Shadow saying the F-word.
  • The Dreamcast version of the game runs a disc check to make sure it is not run from a copied disc. If this check fails, Eggman will fall through the floor when he starts his section of Cannon's Core.[58]

Big the Cat in the Hero story's first cutscene.

  • Big the Cat has six known cameo appearances in the cutscenes of Sonic Adventure 2 that can be only seen by pressing A, these include:
    • During Sonic's escape from the helicopter at the beginning of the Hero story, Big can be seen in the Dreamcast version holding onto it.
    • During Sonic and Shadow's first meeting, Big can be seen running around Shadow while he is standing over the F-6t Big Foot.
    • In the cutscene after Knuckles fought King Boom Boo, Big can be seen standing behind the entrance to the shuttle once the entrance opens.
    • During the cutscene after Knuckles and Rouge's fight, Big can be seen wandering around the arena.
    • During the Last Story's intro, Big can be seen standing on the computer's platform with Eggman.
    • In the Last Story, before Amy tries to persuade Shadow to help, Big can be seen running right and left in the hallway that leads to main room.
  • Shiro Maekawa has stated that he found difficulty in writing the story for Sonic Adventure 2.[59] Despite this, the game's story stands to be Maekawa's favorite as he is emotionally attached to it, as the game is the first story he wrote for.[59]
    • Maekawa has stated that if he had a chance to rewrite it or change something about the game's story, he would only add back the scenes he had to cut.[59]
  • Takashi Iizuka regards Sonic Adventure 2 as his favorite Sonic game as of July 2022.[60]
  • Sonic Adventure 2 is the game with the most original lyrical arrangements in the franchise, with a total of 18.

Notes[]

  1. The word sayonara (さよなら?) means goodbye in Japanese. In the Japanese version, Sonic instead uses the Spanish word adiós, which has the same meaning.
  2. Unlike in other stages, Tails does not employ his shooting gameplay in Route 101, but instead has a gameplay similar to that of Kart Race mode.
  3. Unlike in other stages, Rouge does not employ her treasure hunting gameplay in Route 280, but instead has a gameplay similar to that of Kart Race mode.
