Bethesda Softworks today announced that it plans to make a new content package available for the PC and Xbox 360 version of its popular role-playing game, Elder Scrolls IV: Oblivion. The new content, Knights of the Nine will be made available for the Xbox 360 and Windows via digital download on Xbox Live Marketplace (for the Xbox 360) and www.OblivionDownloads.com (for Windows users) on November 21st. A new retail Windows product will also be released.

The retail boxed release of Knights of the Nine for Windows will be released on November 21st as well and will contain all the other Oblivion downloadable content released to date: Horse Armor, The Orrery, Wizard's Tower, Vile Lair, Thieves Den, Mehrunes' Razor, and Spell Tomes. Bethesda Softworks will publish and distribute Knights of the Nine at retail directly in North America and through a co-publisher arrangement with Ubisoft in Europe.

Beyond that content, Knights of the Nine features an all-new faction and quests for noble characters and answers many of the questions surrounding the Ayleid ruins found throughout Oblivion. Players can join a new faction and found their own order of holy knights - leading them into battle against a sorcerer-king and his demonic minions while exploring massive dungeons and searching for legendary relics - the holy armor and weapons of the Divine Crusader.

This comes on the heels of the September announcement that Oblivion would be making its way to the PlayStation 3 and the PSP next year. The PLAYSTATION 3 version will contain the Knights of the Nine content for those worried about missing out on it on Sony's next-gen platform..
