Today marks the release of Watch Dogs, as Ubisoft now offers the open-world hacking action game also written as Watch_Dogs. The Watch Dogs website has links to locate the dizzying array of different versions of the game, some of which are listed as preorders, and therefore may no longer be available. NVIDIA released drivers and a tweak guide for the game yesterday, and AnandTech says AMD will follow suit today, but a new Catalyst beta is not yet available. The first reviews are online, and here are some of those, with the PC review listed where available: Ars Technica, CVG, Forbes, GameSpot, Hardware Heaven, IncGamers.com, PC Gamer, PC Games (Germany), Polygon, Rock, Paper, Shotgun, Strategy Informer, The Verge, and Worthplaying. Also, this ctOS Mobile App FAQ has details on the accompanying Watch Dogs iOS and Android apps, with links to get them that should go live when they are available. Here's the official description of the game:

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.

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.
