Night of the Mummy

From BoardGameGeek:

The Mummy's curse has brought all the exhibits to life and they've crashed the Museum of Unnatural History's annual masquerade ball! Night of the Mummy is a 20-minute game of hidden roles and logical deduction for 4-8 players aged 10 and up. Each player takes on the role of a classic monster at a masquerade party - identify and expose everyone else to break the curse and escape! A standalone expansion to Dracula's Feast: New Blood, Night of the Mummy improves everything you loved about the original - more roles, unique interactions, and a brand new mechanism: some characters hide while dancing, not revealing their roles to other players! Best of all, combine it with Dracula's Feast! Incorporate roles from either game into the other for even greater replayability! The game comes with 10 unique new roles, including 3 advanced guests. -description from the publisher
