The streets of London are not very safe tonight. A night war is brewing. Will Arsène Lupine, Sherlock Holmes or Van Helsing overcome the Mummy, Frankenstein's creature or even the Dracula tale? Join your faction, recover and play special skills to bring light ... or darkness to London! Each player randomly receives a faction card that they keep hidden. They also receive three cards, which they can, during their turn, either play or draw (within the limit of three cards in hand). If he plays a card he keeps it in front of himself and applies its effect. The winner is the one who scores the most points at the end of the game, the hero cards causing the heroes to score points and lose to the villains and vice versa. —description from publisher
