The Resistance: Avalon is a standalone game, and while The Resistance is not required to play, the games are compatible and can be combined.
Players are either Resistance Operatives or Imperial Spies. For three to five rounds, they must depend on each other to carry out missions against the Empire. At the same time, they must try to deduce the other players’ identities and gain their trust. Each round begins with discussion. When ready, the Leader entrusts sets of Plans to a certain number of players (possibly including himself/herself). Everyone votes on whether or not to approve the assignment. Once an assignment passes, the chosen players secretly decide to Support or Sabotage the mission. Based on the results, the mission succeeds (Resistance win) or fails (Empire win). When a team wins three missions, they have won the game.
