In yet another Xbox Live Arcade deal, Microsoft is now offering a free batch of 400 MS Points for purchasing two qualifying XBLA games. Don't run off downloading games just yet though, because you'll need to head over to the Xbox Live Events page and download the Arcade Offer gamer picture to register for the giveaway first (the direct link to the gamer picture is currently broken, but it's the first one listed on the events page).

Once that's done, snag two of the games listed after the break (including favorites like Limbo, Lara Croft, Monday Night Combat, Super Meat Boy and more). Within four weeks, the free points will be added to registered Live accounts automatically or sent as redemption code via email. If you're planning to pick up any of the eligible games, you might as well get some free points too, right? The promotion ends December 20, so get to it.
