What do you do when a game makes an appearance on every outlet's "Game of the Year" lists? You discount the hell out of the expansion content, of course!
Today's Xbox 360 "Countdown to 2011" deal is on Mass Effect 2's adds-ons, "Lair of the Shadow Broker," "Overlord," and "Kasumi." They're a measly 200 MS Points a piece, which means even if you pick up the worst of the batch (arguably "Kasumi," by most accounts), you're getting a good deal.
Oh, and you can buy a police officer Avatar outfit (female and male) for 120 MS Points today. Yeah, you do that.
