Ubisoft has announced new story content for Watch Dogs that will be available later this month. The add-on stars one of Aiden Pearce’s associates from the main story, T-Bone.

The story takes place after the end of the Watch Dogs story, as T-Bone infiltrates Blume to cover his trail and escape. The Bad Blood add-on includes 10 missions and new activities, including co-op “Street Sweep” missions against criminal factions.

Bad Blood will be available on September 23 for season pass holders. It will be available a week later on September 30. A standalone price has not yet been revealed. For more on Watch Dogs, check out our review.
