The PlayStation versions of the game will also feature one hour of exclusive gameplay accessible via PSN post-launch.
Ubisoft recently announced a Watch Dogs release date of May 27 on PS4, PS3, Xbox One, Xbox 360 and PC, with the Wii U version set to launch "at a later date".
The open-world game was originally scheduled for release in November 2013, but it was delayed due to quality concerns.
In March, a senior figure at Ubisoft Montreal told CVG the studio would have been forced to axe "several" Watch Dogs game systems had the title not been pushed back.
Ubisoft's VP of creative, Lionel Raynaud, revealed that the development team even considered saving these specific systems for a Watch Dogs sequel, but ultimately decided that the additional development time required to implement them would be worthwhile.
