In Ultimate Werewolf, players are given secret roles and asked to find whom among them are werewolves. Meanwhile the players who are werewolves are trying to get rid of everyone else in the village before they are discovered. with a variety of special-powered roles thrown in, games require players to be alert and to deduce the actions of all of the other players in order to survive and win. Ultimate Werewolf Legacy raises the tension and increases the impact of decisions made by the players, as everything that happens will impact future games. Players are each given a public Family Card in addition to their secret role card, and will team up with the other members of their family to work together unless one or more of their family members is secretly working against them. Players can earn special abilities that carry over between games as well.

The Legacy aspect of the game isnt limited to player evolution, however, as the village itself will change over time base on both the decisions of the players and the outcomes of each game session. There are multiple paths that the game may take, and as a result the experience you have playing through the entire game will be different than someone else who is playing with another set of people. This also allows players to play through the campaign multiple times, with a different set of roles, rules, and environments each time.
