Call of Duty: Modern Warfare 2 has been out for like, a hundred years. Whatever the reason for your pathetic, amateurish ranking, you can give yourself a boost by playing during this three-day Memorial Day weekend, when Infinity Ward will be offering double experience across all of the game's cornucopia of platforms.
There, now you have no excuse. Unless you're having, like, a cookout or pool party during the extended weekend. Or if you're going to a baseball game. Or if you're going to the beach ... Those are all pretty great excuses, we suppose.
