The Elder Scrolls IV: Oblivion for PlayStation 3 - recently revealed as a surprise launch title for Sony's next-gen console - will feature a huge, exclusive quest that revolves around a new faction, The Knights of the Nine.
The Cyrodiil-spanning adventure will offer an extra 10-20 hours of gameplay, with your reward being a collection of super-powerful items.
Your mission will be to retrieve a set of kits known as the Crusader's Relics, fulfilling the Knights of the Nine's primary goal. Think of it as an Oblivion-set search for the Holy Grail, only there's a collection of them and they give you +50 bonuses when bashing people's heads in. However, to undertake the task you'll first have to prove your dedication to the Knights by embarking on a pilgrimage across Cyrodiil.
