Ubisoft has released the Bad Blood add-on for season pass holders of Watch Dogs for Windows, PlayStation 4, PlayStation 3, and Xbox One, with the Xbox 360 edition to follow "soon." The add-on brings new content to the open-world action game also known as Watch_Dogs, and word is this will be released for everyone on September 30th. Here are the bloody details:

Watch_Dogs Bad Blood builds upon what made Watch_Dogs a record-breaking success by delivering a potent combination of action-adventure missions, seamless multiplayer modes and open world exploration. In Watch_Dogs Bad Blood, players take on a new campaign starring Raymond “T-Bone” Kenney, the brilliant and eccentric hacker from the original campaign. Players pick up T-Bone’s story as he’s planting a false trail at Blume and receives a panicked phone call from his former Blume colleague, Tobias Frewer, in desperate need of help. T-Bone decides to help Tobias, but quickly realizes the details of his old friend’s story aren’t adding up…

Watch_Dogs Bad Blood also grants players access to Street Sweep contracts, a dynamic new system of side missions offering endless hours of challenges. A first for Watch_Dogs, Street Sweep contracts are playable in co-op, friend or public sessions, allowing two players to work together to combat Chicago’s criminal groups. The popular online Hacking and Tailing modes, as well as the ctOS mobile companion app, are fully playable with T-Bone in Watch_Dogs Bad Blood.

In addition, Watch_Dogs Bad Blood features exclusive weapons, perks and outfits, including the remote-control car, Eugene, T-Bone’s latest creation, which can be upgraded with both offensive and defensive perks.
