Sonic Adventure 2 (2012)

Sonic Adventure 2 is a downloadable version of the original game. It was announced at Sonic Boom 2012 that the game was being re-released on Xbox Live Arcade and PlayStation Network in Fall 2012. It was also released on Microsoft Windows on 19 November 2012.

New features

 * An online leaderboard feature has been added, allowing players to see where they rank in terms of their high scores in each Action Stage.
 * The player has the option to purchase the Sonic Adventure 2: Battle DLC which upgrades the game to Sonic Adventure 2: Battle and includes all features in the GameCube port.

Changes

 * The game has been remastered in 16:9 HD at 720p using the GameCube version's assets (some of the cutscenes remain in their original 4:3 SD format).
 * Almost all of Big the Cat's cameos return in the port, except for his appearance in Wild Canyon due to a programming oversight.
 * "Battle Mode" DLC - This downloadable content features the following:
 * The opening and title screen is changed to "Sonic Adventure 2 Battle"
 * Adds Chao Karate game in single player and multiplayer
 * Automatically adds Amy, Metal Sonic, Tikal, Chaos 0, Chao Walker, and Dark Chao Walker to the two-player character roster.
 * Adds several stages to multiplayer that were only available in Sonic Adventure 2 Battle.
 * Adds the "Theme" item in the Options Menu.
 * The game itself costs $10.00/£6.49, while the DLC costs $3.00/£1.79.
 * All of the billboards with Soap advertising on them have been removed and replaced with other Sonic Team billboard assets (this is most likely due to licensing issues).
 * However, they have not been removed altogether - on the PC version, if the player removes the objtex_stg13.pak file from the PRS folder where the game is saved, the Soap advertisements are restored.
 * Some of the character's life count sprites have been changed. For example, Sonic's sprite resembles the side view of him compared to the original icon.
 * There was an error when you selected the game on XBLA, so for the first day of release, many people were not able to download the game or the trial; this could be circumvented by logging onto Xbox.com and selecting the game's downloads from its page.
 * Omochao appears in the loading screen giving hints and tips (a Sonic Generations model of Omochao is used). This only occurs in the Xbox 360 and PC version; the PlayStation 3 port skips that screen.
 * On the PC (If a gaming controller is used) and the Xbox 360 versions, like the Dreamcast Version, Omochao will eventually speak on how to do an action with a button if the hint is used. On the PS3 version and on the PC version if using they keyboard, he remains silent (except on any hints that does not display any DualShock 3 controller or keyboard buttons).
 * The cross on the Health Packs has replaced with the Letter "H".
 * The GBA in the Chao Garden that was used to transfer Chao has been changed to a machine shaped like a Chao's head, with the only function to release Chao. This is similar to the PC port of Sonic Adventure DX.
 * The XBLA version has a few more glitches, one of which concerns the Hero Garden. If a Chao is fed a fruit from a Hero Garden tree, every time the fruit is eaten, it will raise the Chao's Stamina Stat up 2 to 3 bars instead of the usual 1. This can be used to raise the Stamina Stat very quickly. However, it only applies to the fruit from the trees; taking a fruit in from elsewhere (such as a Chao Fruit from the Black Market) will raise Stamina normally. Other glitches include activating the test level and errors in widescreen cutscenes.
