Select Activision content on sale on XBLM until Jan 17

It's rare you can do something nice at the same time as you get a little something for yourself, but today presents just such an opportunity. Until January 17, you can get tons of discounted DLC, including some XBLA games, from an upstart indie called "Activision" through Xbox Live Marketplace. All the Call of Duty: World at War map packs are just 400 points, for example, and you can find the Guitar Hero: Warriors of Rock "Linkin Park Pack" for just 480 plus our terrible, eye-rolling judgment.

We know it can be daunting to spend your hard-earned dough on a no-name publisher, but trust us: We've been following these scrappy kids, and we feel pretty confident that they're going places. Peruse the full list of discounts after the break.
