The Ultimate Werewolf Extreme base set should be available in retail sometime later in 2021 or early 2022, and will include the base 84 cards and a moderator scorepad. Other cards in this Kickstarter may be sold separately at that time. Other Kickstarter items may or may not be available separately later, depending on availability.
There are over 120 cards that are guaranteed to ship with the Collector’s Edition, and possibly a lot more if stretch goals are met. The number of unique roles is also determined by the stretch goals met. The retail edition will have 84 cards made up of 41 unique roles.
