Ubisoft skriver følgende om det nye indhold:
Watch_Dogs Bad Blood features an all new story campaign starring T-Bone, the brilliant and eccentric hacker players first met in Watch_Dogs, who is now playable for the first time. The campaign explores T-Bone's story through 10 new missions set in new locations throughout Chicago. Shortly after the events of Watch_Dogs, Raymond "T-Bone" Kenney infiltrates Blume one last time to plant a false trail in their system. Before he can disappear from the grid, he receives a panicked phone call from Tobias Frewer, a former colleague from Blume's ctOS prototype days, who's in desperate need of help. Putting his own escape at risk, T-Bone decides to help, but quickly realizes the details of his old friend's story aren't adding up.
