Sonic Adventure 2 is an enhanced digital port of the original game for the Dreamcast that was released on the Xbox 360's Xbox Live Arcade, PlayStation 3's PlayStation Network, and PC via Steam in October 2012.
The PlayStation 3 version was available to be streamed on the PlayStation 4, PlayStation 5, and PC via the PS Now subscription service, with PlayStation 3, PlayStation Vita, Sony Bravia Smart TV (2013, 2014, 2015 and 2016 models), Sony Blu-Ray players, and Samsung Smart TV support for the service being dropped in 2017. The Xbox 360 version was made backwards compatible on the Xbox One in December 2017.
- 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 from the GameCube version.
- The game has been remastered with a display aspect ratio of 16:9 HD at 720p using the GameCube version's assets, although some of the cutscenes, including CG cutscenes, remain in their original 4:3 SD format however.
- 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 the 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.
- All of the billboards with Soap advertising on them have been removed and replaced with Sonic Team billboard assets, this is most likely due to licensing issues.
- However, the ads 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. Also, the Ring sprites resemble their Sonic Generations models.
- Treasure Hunting stages have more Hint Box than they did in previous versions.
- On the first day of the Xbox 360 version's release in Xbox Live Arcade, many players were not able to download the game or the trial from their Xbox 360 console. However, this could be circumvented by logging onto Xbox.com and selecting the game download from the website.
- Omochao appears in the loading screen giving hints and tips, using a Sonic Generations model. This only occurs in the Xbox 360 and PC version, as the PlayStation 3 version skips that screen.
- On the PC, if a gaming controller is used, and the Xbox 360 versions, Omochao will eventually teach the player to do an action with a button if the hint is used. On the PlayStation 3 version and on the PC if using the keyboard, he remains silent, other than any hints that do not display any DualShock 3 controller or keyboard buttons.
- The cross on the Health Item Boxes has replaced with the letter "H", presumably because the Red Cross symbol is no longer allowed to be used in video games.
- The Game Boy Advance 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: Director's Cut.
- The Xbox 360 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 by 2-3 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 the Black Market, will raise Stamina normally.
- The "tutorial" section inside the "Help & Options" section has been changed to "How To Play," which includes a digital manual instead of Omochao. Strangely, the manual is in the original 4:3 SD format.
- The "Help & Options" also includes a bonus video and a credits section.
- The sound when losing Rings has been slightly changed to match the modern Sonic games' version.
- When Super Sonic transitions to Super Shadow in the Finalhazard boss, the lives icon changes as well. In the original, the lives icon will keep Sonic's face even when playing as Super Shadow.
- Shield Hunters with the number "01" have been brought back to Crazy Gadget, although their shields are redesigned to match their equivalents in other stages.
