Set in Chicago, where a central network of computers connects everyone and everything, Watch_Dogs explores the impact of technology within our society. Using the city as your weapon, you will embark on a personal mission to inflict your own brand of justice. In 2016 the game received a sequel - Watch Dogs 2.

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.
