To unlock the badge, fans must follow the Seahawks on foursquare, then check in at their stadium on game days. Presumably the badge will allow users to “level up” as they check in at subsequent games, as the other NFL badges do.
The unlock text reads:
Bigger, Faster, Stronger, Louder! Thanks for creating the best home field advantage in the league. SEA – HAWKS!
The Seahawks join the Redskins, Panthers and Texans as the only teams with their own badges.
What do you think of the badge?
