From the announcement:
Fantasy Flight Games is proud to announce the upcoming release of Blood Bound, a game of deduction, bluffing, and strategy for six to twelve players. You and your clan of vampires must work together to capture the leader of your rival clan. However, your adversaries won’t sit idle as you work. They will be simultaneously working to identify and eliminate your leader. The catch? Everyone is secretly assigned an identity and clan affiliation at the beginning of the game–you can never be truly certain who is your friend and who is your foe!
