The Elder Scrolls IV: Shivering Isles released

The Elder Scrolls IV: Shivering Isles is the first official expansion pack for the computer role-playing game The Elder Scrolls IV: Oblivion.

Announced on January 18. 2007, the expansion was developed, published, and released over the Xbox Live Marketplace by Bethesda Softworks; its retail release was co-published with 2K Games. It was released for Microsoft Windows in a boxed retail edition on March 27, 2007, while the Xbox 360 version was released digitally on the Xbox Live Marketplace.

Shivering Isles takes place on the eponymous isles ruled by the Daedric Prince of Madness, Sheogorath. The player becomes Sheogorath's protégé and together they try to defeat Court of Madness, Jyggalag, and thus prevent the isles from being destroyed. The expansion was generally well-received in the gaming press. Although it made little change to the basic mechanics of Oblivion, it was judged by reviewers to be a good addition to the game, and a must-buy for the fans of the franchise.
