Elder Scrolls Oblivion Question?

Question

Basically I was looking through the achievements list for the xbox 360 version of the game and I came across the shivering isles achievements (e.g tourist, the shivering isles) I was wondering how do I get the shivering isles?? what is it? I heard it was an expansion for the game but I dont know where I can get it, if it costs anything etc. Is the shivering isles downloadable through xbox live? I'm new to the expansion thing and I'm not really sure what it is? can you guys help me out with this??

Answer 1

You can get it in the game of the year edition of oblivion or off of the xbox live market place. originally I heard they were supposed to put out a stand alone copy of the shivering isles for the 360 but I don't know what happeed to that.

Answer 2

You can buy it on xbox live marketplace
