Xbox 360 users will automatically be prompted to download the patch when they connect to Xbox Live. This is the final version of the FormID patch, and was released on. Patch Fixes New Features 10 new Xbox 360 Achievements for Shivering Isles. This patch is available for download for PC users and over Xbox Live for Xbox 360 users. The PS3 version of the game comes with this patch already installed.

No other plug-ins are available for the PlayStation 3. Version 1.2 Oblivion version (commonly known as simply 'Version 1.2') was released on, and is the second official patch to be released by Bethesda for the game. Shivering Isles is also available from the PlayStation Store. Usually GOGs version of a game is the latest patched version, so I assume there isn't any official patches I need to download as well. PlayStation 3 players who purchase the original game will receive the Knights of the Nine plug-in, and those who purchase the Game of the Year edition will receive the Knights of the Nine and Shivering Isles plug-ins. I suppose I'll download them when I get home from work.

All of the plug-ins are available from the Xbox Live Marketplace individually. Xbox 360 players who purchase the Game of the Year edition will receive the Knights of the Nine and Shivering Isles plugins on a second 'install only' disk.
