Bethesda recently developed some add-on content for their huge Xbox 360 RPG, Oblivion, and have put it up on the Xbox Live Marketplace for free under the name “Mehrunes Razor.”  Mehrunes Razor used to cost 250 pts, but because of the festive spirits of Bethesda, Oblivion owners can obtain this expansion for free.  Be warned, the pack will only be available free until December 31st, so hop on this deal!  Here’s the game-description from Major Nelson (via YouNEWB):

The lost Ayleid City Varsa Baalim has been unearthed by a rogue Telvanni arch-mage, in pursuit of a fearsome Daedric Artifact, Mehrunes Razor, which he believes will give him the power he needs to topple the Imperial reign – but what horrors lie in wait beneath the Valus mountains; and can you overcome them to claim Mehrunes Razor as your own?

Features:

A fully-featured quest takes you deep into the fringes of the Niben.
Earn the fearsome Mehrunes Razor, with the ability to kill foes instantly.
17 new magic items to discover!
Conquer the largest dungeon in all Cyrodiil.
Thwart a plot to overthrow Imperial rule in Tamriel.
12 new books, notes, and journals to help you unravel the mystery.

1up reports that Bethesda will be releasing Oblivion’s first official patch for both the PC and the Xbox 360 versions of the game.  Joystiq elaborates, stating that “PC users will get the patch via normal outlets, while Xbox 360 owners will get their patch via Xbox Live and other, unspecficied means (chief of PR Peter Hines mentioned looking into bundling the update with the Official Xbox Magazine).”  This is the sure-fire way to remedy the many minor (and a few major) glitches with Oblivion.
