Chicago's overarching network is known as the Central Operating System (ctOS), and it controls almost all of the city's technology and information—including key data on all of the city's residents.
You play as Aiden Pearce, a brilliant hacker and former thug, whose criminal past led to a violent family tragedy. While seeking justice for those events, you'll monitor and hack those around you by manipulating the ctOS from the palm of your hand. You'll access omnipresent security cameras, download personal information to locate a target, control traffic lights and public transportation to stop the enemy, and more.
Using Aiden's smartphone, you have real-time control over the city's infrastructure. Trap your enemy in a 30-car pileup by controlling the traffic lights. Stop a train, and then board it to evade the authorities. Anything connected to the ctOS can become your weapon.
Deliver devastating blows with your baton, or experience electrifying shoot-outs with physics simulation that rivals anything in the shooter category. Throughout his journey, Aiden will take on his foes with more than 30 traditional weapons.
Command a suite of vehicles bursting with horsepower. You'll get behind the wheel of more than 65 cars, each with state-of-the-art physics and handling, to explore Chicago's vast and intricate roadways.
Not only does Watch Dogs give you the ability to take advantage of the ctOS, it also allows you to explore the many layers of Chicago itself. Cut through buildings, scale rooftops, and explore the city's dangerous underground to catch your target.
