• The way lights and shadows work differently in the GameCube version:
  • The GameCube version removed most of the shadows, as the shadows did not have any kind of fading, so they looked awkward in the cutscenes.
  • The lighting in this version affects the characters, but not any Level Up Items that they are wearing. Also, there are rays of light from specific sources that are missing in the GameCube version.
• Almost all of Big the Cat's cameos in the Dreamcast version have been removed in the GameCube version, with the only remaining ones seen being those in the Dark story and Last story.
• The GameCube version adds a short opening sequence with Sonic and Shadow at Radical Highway before the title screen. In addition, there is a small intro clip of the title of the game popping into view extravagantly in space. On top of that, the title screens are a bit different, but use the same music.
• In the options menu, the Dreamcast's Sound Test menu was replaced with the ability to delete the multiplayer records in the GameCube version.
• When the game is switched to Japanese text, the Dreamcast version does not translate the main menu or the "Now Loading" indicator. This is fixed in the GameCube version.

• In the cutscene when Sonic jumps off the helicopter, he wears the Grind Shoes the entire time, unlike in the Dreamcast version where he mistakenly starts out by wearing his original shoes. The angles and lens flare are also different.
• In the cutscene where Sonic and Shadow meet for the first time, there are a few changes between the Dreamcast and GameCube version:
  • Sonic loses some expressions; his ear moves in the Dreamcast version when he hears Shadow has landed on the crashed Big Foot and his eyes squint when Shadow leaves. In the GameCube version, none of this happens.
  • The pilot of the crashed Big Foot is missing in the GameCube version.
  • Sonic and Shadow are very bright in the GameCube version, as the lighting on the updated models seems to be incomplete. More accurate lighting is also used before Sonic notices Shadow in the GameCube version.
  • The camera is further away from Shadow when he performs Chaos Control in the GameCube version.
  • Some background objects were added to this cutscene, such as signs.
  • The officers' voices are cut off short and overlap each other in the GameCube version. In the Dreamcast version, the officers shout at Sonic in full sentences.
• In the first encounter between Knuckles and Rouge has been tweaked slightly in the GameCube version. In this version, Rouge looks up at Dr. Eggman and screams just as the Master Emerald is broken, overlapping Eggman's quiet exclamation. She is then seen just starring with her mouth open. In the Dreamcast version, a different camera angle is used when Rouge looks up at Eggman, and she screams after the Emerald is broken, namely while she is looking up.
• The bars of Sonic's cell cast do not cast shadows in the GameCube version. In the Dreamcast version, they do.
• When the President talks with Dr. Eggman in his limo, more static and interference has been added to Eggman's video screen in the GameCube version.
• During Rouge and Shadow final meeting in the Hero story, Rouge's theme in the background now changes to Maria's theme in the GameCube version. In the Dreamcast version, Rouge's theme is played throughout the whole cutscene.
• Camera angles in most cutscenes were altered, ranging from more relevant shots to simple zoom-outs.
• When Sonic and Shadow meet for the second time in the GameCube version, the air is clear. In the Dreamcast version, there was a vague, teal mist.
• When Sonic and crew find Dr. Eggman's pyramid base, the sun shines undisturbed across the screen in the GameCube version. In the Dreamcast version, the sun caused lens flares.
• When Sonic and crew reach the pyramid base's locked door, the neo lights in the shape of Eggman's logo in the Dreamcast version have been removed in the GameCube version. Also, in the final shot of the cutscene, Sonic is shown from an angle different from the one in the Dreamcast version while making a different pose.
• When Sonic, Tails, and Amy first arrive on the Space Colony ARK in the GameCube version, the hallway they stand in has red stripes along the floor and walls that follow the rest of the patterns. In the Dreamcast version, there are no red stripes.
• As Sonic is about to insert the fake Emerald into the Eclipse Cannon in the GameCube version, the other Chaos Emeralds can be seen in their slots behind a transparent screen. In the Dreamcast version, these slots are empty.
• In the cutscene when Sonic tries giving Dr. Eggman the Fake Emerald in the GameCube version, Sonic can be seen reaching out further into the middle of the room before he is encapsulated. In the Dreamcast version, Sonic is only shown reaching the edge of the circular area before he is encapsulated. He also moves his arms a little less in the Dreamcast version when captured, and appears to be more alarmed.
• When Dr. Eggman is holding Amy at gunpoint in the GameCube version, his gun's lens from the Dreamcast version is removed.
• In the cutscene before the final battle between Shadow and Sonic in the GameCube version, the fake Emerald Sonic is holding is missing a shine effect from the Dreamcast version.
• Sonic uses his updated model from the Dreamcast version when he holds the fake Emerald and when he runs into the distance before fighting Shadow in the GameCube version.

• When Dr. Eggman breaks into Iron Gate, the background in the GameCube version shows Eggman at a bend in the hallway, as opposed to having just walked through a door in the Dreamcast version. Also, the red emergency lights are stronger in the GameCube version.
• When Dr. Eggman is watching the news report in his secret base in the GameCube version, the screen is slightly transparent to better fit with its border, but the glow from the screen is missing. In the Dreamcast version, the screen is fully opaque and gray before Eggman turns it on.
• When Rouge breaks into Dr. Eggman's base and looks through his computer in the GameCube version, the text from the transparent screen is laid overtop of Rouge, to give the appearance of the camera being behind the transparent screen. Also, the glow from the screen in the Dreamcast version is missing in the GameCube version.
• When Shadow announces the true power of the Space Colony ARK to Dr. Eggman in the GameCube version, the brilliant flash that comes from the screen at some point in the Dreamcast version is missing, although Shadow still lights up as if it were there.
• When Amy mistakenly hugs Shadow in the GameCube version, the lens flare and flashing lights that appear at the beginning in the background on the Dreamcast version are removed. In the GameCube version, Amy also turns her head more while hugging Shadow than she did in the Dreamcast version.
• When Rouge is trapped in Security Hall in the GameCube version, the three Chaos Emeralds around her are now nowhere to be seen. In the Dreamcast version, Rouge is surrounded by the three Chaos Emeralds that she had just collected when the scene cuts to her.
• When Shadow watches Tails fly past in Sky Rail in the GameCube version, the sky box's image is higher than in the Dreamcast version.
• The computer Rouge looks through on the Space Colony ARK displays completely different screens:
  • In the Dreamcast version, it looks as though she is actually looking through the computer and finding the info on Project Shadow, with windows popping up sequentially, complete with a picture of the Biolizard. Before Rouge decides to go get more shards of the Master Emerald, a new window simply pops up saying that it was detecting energy from the Master Emerald, which was what prompted this decision in the first place.
  • In the GameCube version, windows phase in and out of view in a more fictitious manner, with a "WARNING" message added to go with Rouge's reaction. Before Rouge leaves for Mad Space to find the Emerald shards, the screen shows the same WARNING message and a camera feed of Sonic and company, as if this is what prompted her to leave.
• When Dr. Eggman discovered that Tails made a fake Chaos Emerald, the scene begins with Eggman looking at a camera feed of Sonic. There is a small window in the upper left corner that Eggman enlarges:
  • In the Dreamcast version, it is an image of a map of the Space Colony ARK that shows two Chaos Emerald readings.
  • In the GameCube version, this is the same video feed of Sonic and his crew that Eggman was already looking at.
• In the Dreamcast version, when Shadow watches Sonic's capsule blow up, the earth is in view. In the GameCube version, the earth was removed completely. This was changed to prevent the scene from looking like the capsule hit earth, when it really just exploded in space.

Last Story

• When Rouge reads Gerald Robotnik's regrets about creating the Ultimate Lifeform, there are a handful of minor alterations in the GameCube version:
  • Vertical lights are added on either side of the door.
  • Once Rouge finishes, the door of the room is has now been mysteriously opened in the GameCube version. IN the Dreamcast version, it remains closed.
  • After Sonic does his pose, his head moves slightly in the GameCube version to make him look more natural. IN the Dreamcast version, he stands still.
• When Sonic and Knuckles encountered the Biolizard, the slightly transparent clip of Gerald that is made full screen for a moment was mistakenly put over the subtitles on the Dreamcast and were not very easy to see as a result. This was fixed in the GameCube version.
• When the credits begin, Sonic hands Rouge one of Shadow's Limiter Rings. This Ring is changed from being half orange, half yellow in the Dreamcast version to being completely yellow in the GameCube version.
• The Space Colony ARK is closer to the earth in the GameCube version. Also, any glass reflections are lost.
• The lines during the credits were rearranged in the GameCube version, but keep most of the same elements.

Gameplay

• Big the Cat's cameos have been removed from the stages, oftentimes replaced with a Ring. He has also been replaced by a Dark Chao in the multiplayer mode.
• The 1-Up icons were changed slightly in the GameCube version:

Dreamcast:	File:SonicAdventure2 LifeBoxIcons.png
GameCube:	File:SonicAdventure2Battle LifeBoxIcons.png

• Tails and Dr. Eggman's Lock-on technique now utilizes a faster system and are able to Lock-on every 8 frames, as opposed to 12.
• The first frame of Knuckles' Spiral Upper and Rouge's Screw Kick roughly double the reach in the Dreamcast version. This was changed in the GameCube version, leaving them with only the same reach as the rest of the move. Additionally, more objects were given immunity to those moves in the GameCube version, such as the Safes around the perimeter of Security Hall.
• Knuckles and Rouge could Climb on and Dig into walls underwater in the Dreamcast version. These mechanics were removed in the GameCube version.
• When Sonic completes a stage, his pose is the same between the versions. However, whereas he does not directly look at the camera in the Dreamcast version, he looks directly into the camera in the GameCube version.
• On the Dreamcast version, when Eggman or Tails gets hit with a Shield equipped, they lose health on top of losing the Shield. In the GameCube version, they only lose the Shield.
• All of the characters in the GameCube version run slower than in the Dreamcast version.
• Treasure hunting stages feature an additional level of detection in the GameCube version: an exclamation point in a red action bubble will appear above the character's head once they are within reach of the object of their search.
• The game's graphics have been tweaked:
  • Some of the writing on the G.U.N. mechs has vanished under the textures in the GameCube version.
  • In the Dreamcast version, many of the G.U.N. robots have blue fiery jets to keep them floating/moving; in the GameCube version, all that is left are the jet nozzles.
  • In the GameCube version, Amy's teeth are no longer prominent and Maria Robotnik's eyelashes are removed.
  • In the GameCube version, the lighting no longer pulses down the screen like it did in the Dreamcast version, like in Egg Quarters when the player encounters the Egg Beetles, or Iron Gate when a security sector has been breached. Lighting in general, was heavily adjusted, with some areas receiving more clarity and others being simplified.
  • In the GameCube version, some visual effects are different altogether in comparison to their Dreamcast counterparts, such as White Jungle now featuring have rain instead of purple spores floating down. Graphical glitches were also reduced.
• In the GameCube version, some stage layouts and Rank requirements in the Dreamcast version were adjusted for better flow.
• The title screen and the main menu screen have been changed and reorganized.
• Posters in the stages have been changed.

• The Dreamcast version featured the "Download Event" mode where the player could access various events, although on a far smaller scale than Sonic Adventure. Some features included a Halloween and Christmas theme for the character Outfits in 2P mode, as well as three additional race tracks. The GameCube release added a selectable Eggrobo racer and expanded character themes for the menus (which was noticeably missing Shadow).
  • Some of the themes' character Outfits have been altered in the GameCube version. Now, they are unlockable features in the 2P mode that can be accessed by getting an A Rank in all of the characters' stage missions. When used, these Outfits enhance the character's abilities or make the required amount of Rings for they special abilities lesser.
• In the GameCube version, Knuckles' segment of Cannon's Core has been made easier by placing boxes below the areas where he gets air bubbles. When Knuckles takes one of these Bubbles, he sinks a few inches. In the Dreamcast version, taking in air would make him sink and touch the hazardous ground and take damage. Because of the boxes in the GameCube version, Knuckles can can now take in the air bubbles without getting hurt.
• The song "Deeper", for Death Chamber, removed Sonic and Knuckles' conversation and replaced it with a saxophone solo in the GameCube version. The reason for this was most likely because Sonic says, at the final lyric of the "conversation", "Ya damn right, Knuckles!"
• The Balloons and bodies of Artificial Chaos were made fully opaque in the GameCube version, as opposed to being slightly transparent in the Dreamcast version.
• The Shield Hunters' shields were redesigned in the GameCube version, being made narrower and more revealing than their Dreamcast counterparts. There is also a "01" shield variant in the Dreamcast version that was removed in the GameCube version.
• Japanese language settings are set as the default in NTSC-J copies of the game in the GameCube version. This was not the case in the Dreamcast version (similar to Sonic Adventure International).
• The "TIME EXTENDED" text in Route 101 and Route 280 no longer overlaps with the pause menu in the GameCube version, unlike in the Dreamcast version.
• A border was added to the Mystic Melody doors in the GameCube version.
• The bright light that appears under the playable character when travelling over transparent floors in the stages set onboard the Space Colony ARK looks slightly different in the GameCube version.
• In the Dreamcast version, each stage (excluding Route 101 and Route 280) has a maximum Ring count, and upon completion of the stage, the game tells the player how many they collected of this maximum. These maximum Ring scores have all been changed between the Dreamcast and GameCube versions, varying anywhere from one Ring to more than fifty. The only exceptions are Prison Lane, Metal Harbor, Pumpkin Hill, Mission Street, Aquatic Mine, and Meteor Herd. The reason for these changes are unclear:

Stage	Dreamcast Ring count	GameCube Ring count
City Escape	436	424
Iron Gate	120	138

2P Mode

• Amy Rose, Chao Walker, Tikal, Metal Sonic, Dark Chao Walker, and Chaos are available at the start of the multiplayer mode and have their own movesets in the GameCube version. In the Dreamcast version, the characters were originally only selectable between "Hero" and "Dark", and bonus characters performed exactly like their 1P counterparts with no unique voices, aside from Amy who had reused voice clips from the single player mode.
• The 2P Mode has more stages and settings in the GameCube version.
• In the 2P Mode, each character was given a unique background for their special attack animations.

• The Hero and Dark Gardens were made slightly smaller in the GameCube version in comparison to the Dreamcast version. Along with this, all three Chao Gardens have been given slight modifications:
  • The Dark Garden in particular looses the blood-red body of water and the ramp leading up to another tombstone in the GameCube version. It also looses the large cliff with a cave hidden underneath in the GameCube version, as it has been replaced with a simple tree.
  • In the Hero Garden, there is no longer a river and bridge in the GameCube version, although the pond around the fountain was made bigger to compensate.
• The Neutral Garden has lost the rock wall blocking its exit in the GameCube version and has had it replaced with a more natural cave exit.

• Neutral Garden entrance (Dreamcast)

• Omochao no longer welcomes the player to the Chao World in the GameCube version.
• In the GameCube version, the Chao World theme was moved to the new Chao Stadium, and in its place is the Chao Race menu theme from Sonic Adventure.
• In the Dreamcast version, the player could still use attacks in the Chao Gardens, like in any Stage. In the GameCube version, while they can still be selected on the action command, the attacks are not automatically available so that the players cannot accidentally hurt their Chao.
• The fruit from the trees and on the ground would reset in the Dreamcast version every time the garden is entered. In the GameCube version, the fruit does not reset.
• In the Dreamcast version, the only way to name a Chao and see its stats was to send it to Chao Adventure 2 on the Dreamcast's VMU. In the GameCube version, the Fortune-teller lets the player name Chao, and the player can now see the Chao's stats when they pick them up.
• In the Dreamcast version, Chao stats could reach 999 in each stat. In the GameCube version, grades were added to Chao stats to make the system a little more interesting. These grades affect how high the stat can reach, and if the Chao has reincarnated, these grades will be enhanced based on the Chao that died.
• In the GameCube version, Chao make more idle sounds.
• In the Chao Lobby in the GameCube version, it is easier to prompt an exit from the center of the lobby, as the player snaps to the platform. It was noticeably more precise in the Dreamcast version.
• In the GameCube version, the Chao Race main menu music from the Dreamcast version has been moved to the Transporter Machine.
• In the GameCube version, the menu for leaving the Chao World was redesigned:

• Chao World exit menu (Dreamcast)
  Chao World exit menu (Dreamcast)
• Chao World exit menu (GameCube)
  Chao World exit menu (GameCube)

• In the GameCube version, the Transporter Machines in the Hero and Dark Gardens are no longer stylized like in the Dreamcast version. Instead, they use the same model as the Neutral Garden.
• In the GameCube version, the Chao Kindergarten, left to right from the entrance, features the Black Market, bulletin board, the Classroom, the Principal, the Medical Center, and the Fortune-teller. This is changed from the Dreamcast, in which the order from left to right is Medical Center, Classroom, bulletin board, and then the Principal. Along with this, various other changes were made to the Chao Kindergarten.
  • In the GameCube version, the small table in the middle of the kindergarten has been removed.
  • In the GameCube version, the main room of the kindergarten features different color tones.
  • In the Dreamcast version, the Nurse Chao in the Medical Center would offer a comment about the specific Chao that was brought to them ("This Chao likes Sonic", "This Chao is not a good swimmer", etc.). In the GameCube version, they now gives a full report of the Chao brought to them.

Sonic Adventure 2: Battle received generally positive reviews from critics with a score of 73% from Metacritic, although lower than that of the original Dreamcast version. Critics praised the gameplay and graphics, but criticized the camera movements and some of the character's scripts. IGN motivated the "blistering framerate, sharp and detailed textures, and even progressive scan support", but had negative reviews on both voice acting and sound effects.

Sonic Adventure 2: Battle was the #1 selling title on the Nintendo GameCube in its first week of availability, selling 2.56 million copies in total.

In retrospect, Sonic Adventure 2: Battle was placed as the third best Sonic game by IGN in their "10 Best Sonic Games" list.

Trivia

• There are several options from the original that were left unused and partially removed in Sonic Adventure 2: Battle which include:
  • Internet: If brought back through hacking and selected, will return the game to the title screen.
  • Downloadable Events: This was used to play downloadable Kart Race tracks. This option is mostly removed in the game files.
  • The original multiplayer mode: This still exists in the game files and is mostly functional, with the exception of some graphical bugs, as every match appears to be Shadow vs. Eggman, and the lack of alternate Outfits.
  • TV Settings: Used to switch between 50Hz and 60Hz televisions. While the menu itself works, selecting either option does not actually affect the game. Furthermore, the TV Settings menu uses the theme selection icon in the options menu instead of its regular one.

• 2 Player stages where the Goal Ring was moved to an earlier point, such as White Jungle, still contain objects from the original stage past the area where the new Goal Ring. Other 2P stages only have individual objects or features loaded on areas that have been made inaccessible in the multiplayer mode.
• In the Steam version's files, there is a sound file called "ChaoNet Menu unused" which is never played in game, and there are only two other files where "ChaoNet" was mentioned. This could mean Sega had planned to add something called "ChaoNet" back in development but scrapped it.
• Some unused dialogue, including some Omochao quotes, were implemented into Sonic Adventure 2: Battle as an Easter egg if Sonic or Shadow is to carry Omochao into the Goal Ring.
• While paused, holding Template:Y Button (GameCube) + Template:X Button (GameCube) will make the menu disappear, giving the player a clear view of the screen.
• In all versions, the in-game screenshots in the Tutorial and Credits originate from the Dreamcast release. While some noticeable differences, such as the different-colored select button, the treasure hunting exclamation point, and the controller graphic were added, one can see there are no new screenshots due to Dreamcast-only things appearing, such as the altered posters in the background of City Escape, the inscriptions on the mechs, and the Space Colony ARK's screen at the end of Dark story reading "DANGER!! DANGER!!" rather than "WARNING!! WARNING!!".
• The advertisements for the game show several real life hedgehogs being trained to take on the roles of Sonic and Shadow.
