This week on Xbox Live: Expansions for Battlefield 3, Assassin’s Creed Revelations, and Gears of War 3

Microsoft has expanded Xbox Live to enable new entertainment options such as YouTube and Verizon’s FiOS TV, but the bread and butter of the Xbox 360 remains games.┬áThis week will see a slew of attention-grabbing new content on Xbox Live for some of the year’s biggest titles. Battlefield 3 finally gets its Back to Karkand expansion, available for $15, or free to those who purchased the Battlefield 3 Limited Edition retail package. Gears of War 3 kicks off its 12 Days of Gearsmas celebration with the RAAM’s Shadow campaign. You can read my review here. I didn’t like it. And Assassin’s Creed Revelations receives the first of several content bundles with the Ancestors Character Pack, which adds a few new faces to the multiplayer.
