Watch Dogs’ mobile app is a hoot as you chase down a fugitive across Chicago (hands-on preview)

Ubisoft’s upcoming video game Watch Dogs is totally fun to play as I discovered in a hands-on demo of the cyber-hacker vigilante game at a preview in San Francisco. But I was surprised to learn how much I enjoyed playing a companion mobile app, where you can get an overhead view of the city and dispatch resources to track down a fleeing vigilante.
