Watch Dogs - PlayStation 4 Announcement Walkthrough

Players will assume the role of Aiden Pearce, a new type of vigilante who, with the help of his smartphone, will use his ability to hack into Chicago’s central operating system (ctOS) and control almost every element of the city. Aiden will be able to tap into the city’s omnipresent security cameras, download personal information to locate a target, control systems such as traffic lights or public transportation to stop a chase, and more. The city of Chicago is now the ultimate weapon.
In Watch_Dogs, players will experience the realities of living in our fully connected society, where individuals and corporations are at risk of exposure by our ever-increasing reliance on networks and technology.
