Masters of the Night

From BoardGameGeek:

As you wake up from the rattling sounds of a train, you realise that you will soon arrive to a new place, destined to become either a new haven or a final grave for your family. No doubts, there will be new beginnings in this new city. But your current state is unsightly at best - forced to hide in a luggage car, within boxes full of dirt. All this is to protect your family until they can wake from their slumber. You all spent too much time dreaming. Years, maybe even decades. But now it is time to take matters back into your hands. Play as a member of a Vampire family, just arrived after a long journey in a new, unfamiliar city. Will you survive and establish your rule? Who are the mysterious Agents trying to stop you? Masters of the Night is a fully cooperative board game for 1 to 5 players. -description from the publisher
