The E3 trailer for Watch Dogs (also written as Watch_Dogs and WATCH_DOGS to make sure we're watching), Ubisoft's upcoming open-world hacking game. Here's a description of the game: "In Watch Dogs, players will be immersed in a living, breathing and fully connected recreation of Chicago. 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."
