The first major expansion pack for Bethesda's The Elder Scrolls IV: Oblivion, and it's out now on Xbox Live. The Shivering Isles add-on weighs in at a mighty 994MB, and will set fans of the excellent Oblivion back 2400 Microsoft points. Or about 20 GBP, if you prefer. The PC version of the add-on will be out this Friday, costing about the same.
The expansion introduces the realm of Sheogorath, slotting-in an estimated 30 hours of new gameplay, bolstered by quests, animals, weapons and all manner of new goodies which Oblivion fans should relish.
