On a quest to spend at least 2400 Microsoft Points before the month is out? BioWare, it seems, wants to help out -- both Kasumi's Stolen Memory and Overlord DLC packs for Mass Effect 2 are dropping to $5 a pop (down form $7), as part of next week's XBLM deal. It may be called the "Deal of the Week," but in this case, we prefer calling it "The Obvious Purchase."
