Deception: Undercover Allies is the first expansion to Deception: Murder in Hong kong, a critically-acclaimed social deduction game. In Deception: Undercover Allies, new roles give special powers to both teams and expand the max player count to 14. More means and clue cards increase the possible solutions to the crime. Fresh scene tiles bring more life to the forensic scientist's descriptions. And a new event challenges the already tenuous trust which exists among the investigators.
