2013 Update: For anyone looking for a 2013 badge, it appears we are all out of luck. The game has already begun and there is no sign of a foursquare Super Bowl badge.
According to a MattersofGrey tweet, foursquare is apparently giving additional points tonight for check-ins that include certain game-related keywords:
earn extra @foursquare points today by shouting “ravens” and/or “harbowl” and/or “niners” and/or “super bowl”

To earn the badge, all you have to do is check-in to the Super Swarm (search for it) on Super Bowl Sunday.
