Do You Need the Original Oblivion Disc to Download Shivering Isles on Xbox Live?

No. You don't need the original Oblivion disc to download Shivering Isles via Xbox Live.

How It Works

• Digital downloads: Xbox Live purchases download directly to your console's hard drive. The physical disc is unnecessary after installation.
• DLC requirement: Shivering Isles is an expansion pack. You need the base Oblivion game installed, but not the disc.

Requirements

• Valid Xbox Live account for purchase/download.
• The disc is needed if installing the base game on a new console for the first time.
