Ubisoft has announced a new downloadable content pack for Watch Dogs, starring Aiden Pearce's hacker ally T-Bone.

Called Bad Blood, the DLC lands on September 23 for Season Pass holders, and will become available on September 30 for all others.

The campaign spans 10 missions set across 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 realises the details of his old friend’s story aren’t adding up.

Bad Blood also comes with new side missions called Street Swap Contracts. These are playable in cooperative mode. Online hacking and trailing, and the ctOS companion app are all fully playable as T-Bone.

The DLC also introduces new weapons, perks, and outfits, including a new remote controlled car called Eugene, which can be upgraded "with both offensive and defensive perks."
