Within the Realm of Sheogorath, players can explore the two extreme sides of the god's madness – the sublimely creative and the completely psychotic. Something is happening to the Shivering Isles and Sheogorath himself looks to you to be his champion and defend his realm and its inhabitants from destruction. Do you have the strength to survive his trials, tame a realm fraught with paranoia and despair, and wear the mantle of a God?

The Shivering Isles features a bizarre landscape split between the two sides – Mania and Dementia – filled with vast, twisting dungeons mirroring the roots of the trees they are buried within. You'll encounter more than a dozen new creatures including hideous insects, Flesh Atronachs, skeletal Shambles, amphibious Grummites. Throughout your adventure, you will discover all new items, ingredients, spells, and more, and have the talented craftsmen of Crucible and Bliss forge new armor and weapons just for you.

Features :

• See a world created in Sheogorath's own image, one divided between Mania and Dementia and unlike anything you've experienced in Oblivion.
• Battle the denizens of Shivering Isles, a land filled with hideous insects, Flesh Atronachs, skeletal Shambles, amphibeous Grummites, and many more.
• Find and wield new weapons and armor, or have new ones forged for you by the talented craftsmen of Crucible and Bliss.
• Explore a bizarre landscape filled with twisting, vast dungeons buried within the roots of the trees themselves.
• Unravel the mystery surrounding the endless cycle of madness and destruction that threatens to destroy the Shivering Isles.

The PC version of Shivering Isles will be available at retail and is co-published by Bethesda Softworks and 2K Games, while the Xbox 360 version is currently planned for release through Xbox Live by Bethesda Softworks.
