Elder Scrolls IV: Oblivion expansion Knights of the Nine is now available to download from Xbox Live Marketplace for 800 Microsoft points (GBP 6.80 / EUR 9.30).
Featuring a significant new quest line, new enemies and items, Knights of the Nine is the biggest add-on Bethesda has released for the game so far.
A boxed PC version, featuring all the previous Oblivion add-on items (yes, horse armour and everything), is due for release this Friday in Europe through co-publisher Ubisoft.
The standalone Knights of the Nine quest should be available for PC owners to buy for US$ 9.99 through OblivionDownloads.com on 4th December.
And, as you'll know if you've been keeping up, the forthcoming PlayStation 3 version of Oblivion will include Knights of the Nine from day one - but you won't be able to pick that up for a while, not least because the PS3 isn't out in Europe until March, but also because the game was recently delayed until Q1 2007.
