Ubisoft has released details on the exclusive content featured in the PlayStation 3 and PlayStation 4 versions of Watch Dogs.

As previously confirmed the content represents 60 minutes of additional gameplay, and includes four extra missions set after lead character Aiden Pearce "catches the eye of DedSec".

"The scenario takes place after Aiden Pearce, the vigilante hero of Watch Dogs, catches the eye of DedSec, a notorious hacker group fighting for freedom and security in the digital age," says Ubisoft. "Aiden receives an encoded message asking him to help some members of this organization who want payback. Pearce must use his knowledge of Chicago's complex ctOS network to discover digital vulnerabilities in Umeni Technologies' security network and earn his reward."

As well as the four missions, the content also provides players with an exclusive 'Superior Capacity' hacking boost that offers an additional battery slot once completed.

The DLC will also be included in the PS3 and PS4 bundles due to launch alongside the game on May 27.
