Our friends @foursquare have built a really awesome and fun service, but they have also built a really amazing and useful backend of places, and social and contextual information about those places.  So we decided that it would be cool to use that data to make Mobzombies more place-aware!  When you are in mission mode, and you scan for zombies, you are really scanning the foursquare dataset and generating zombies based on how many people have been at a given place, or how many people might be at that spot at that very moment.  If you are a foursquare user, we also allow you to sync your account with mobzombies, giving you access to some special foursquare related stuff like checking in, or sending shouts based on your kill counts (you know, that kind of fun stuff).

Scanning for hordes!
