When you hear the word 'exclusive' these days don't be fooled. No sooner is something exclusive than everyone else wants a piece of the action.

Today's example is the Knight of the Nine Mission for Oblivion which Sony were very happy in confirming would be a title exclusive to Playstation 3. The mission will add an extra 10-20 hours of gameplay to the award winning RPG and will now appear on Xbox 360 and PC.

The Knights of the Nine mission will see you searching for Crusader relics, which when found unleash a +50 bonus when attacking foe.The pilgrimage will see you wandering around the wilderness in search of shrines (these won't appear on your map), and once found you'll be set a quest in order to prove that you deserve to be given these rare items. TheKnights of the Nine faction will allow interaction with new characters, enemies and places

To complete the new mission you won't be allowed to commit any crimes in Cyrodil, if you do you'll have to start the mission all over again.

The Knights of the Nine Mission will be available on November 21st. [advert]
