Unleash the Beast. The Wolf and the Rat is an expansion for Vampire the Masquerade Rivals ECG that adds two new clans: Gangrel and Nosferatu. Connected through animalism, but divided by opposing loyalties, the Gangrel and Nosferatu provide ample opportunity to unleash the beast within and explore the more feral side of their clan's animal nature. You may play these two clans head-to-head with the pre-constructed decks provided, or integrate them with your Core Set and other expansions to create unique strategies for conquering your foes!
