Microsoft has announced the Xbox Live Marketplace content schedule for December and it's a real doozy. The Deals of the Week -- usually a haven for long-forgotten or unwanted DLC -- are actually real deals this month. In particular, Shadow Complex will be dropped from 1200 ($15) to 800 ($10) during the week of December 21. The following week, starting December 28, Twisted Pixel's The Maw will fall from 800 ($10) to a miniscule 400 ($5). In addition to the normal Deals of the Week, Microsoft will also be offering daily deals from December 18-31. The company didn't specify what any of those deals will be, though it promises discounts on "games, movies, blockbuster game add-ons, holiday themes, you name it!" Rest assured, we'll be keeping our eye on things once the deals start rolling. In the meantime, check out the XBLM December schedule, including Deals of the Week, Games on Demand and XBLA after the break.
