Watch Dogs will be available for PS4, PS3, Xbox One, Xbox 360 and PC from 27 May and its one of the most eagerly anticipated games for all platforms. And has been for some time.

Since E3 2012, where it was first teased from inside a cupboard (of sorts), it has been talked about in every credible circle. And even a delay in release, forced by Ubisoft to give the final product even more polish, has not dampened spirits.

Along with its release, the games publisher will also make available a digital eBook novel based in the same universe as Watch Dogs, but it will feature different characters and a different storyline.

Watch_Dogs //n/Dark Clouds is celebrated Cyberpunk author John Shirley's take on the mythos surrounding Watch Dogs and the technology-hacking theme.

Watch Dogs 2 review: Can you teach an old Dog new tricks?

It is thriller positioned as a direct sequel to the events experienced in the game, but can be read on its own too.

"Working on Watch Dogs was enormously interesting to me because its world offers the convergence of cyberpunk and the edgy tech reality of our times; it all plays out with action and energy against the inner city backdrop that I thrive in,” said Shirley.

"With hack tech in one hand and gun in the other, Aiden Pearce is a believable fusion of hacker and action hero who deliberately slips between the cracks of society to relentlessly pursue his agenda. The novel introduces Mick Wolfe, an ex-military, who get caught in a dangerous game in Chicago’s hyper connected and violent underground."

The book will be available in two digital editions; a standard eBook and an upgraded version with interactive elements, including videos and images.

Pricing is yet to be revealed.
