FN BS: The Game

Description from the publisher:

FN BS is a micro card game based on the seven deadly sins and Truth, also known as Veritas. It's a game filled with deception, perseverance, and strategy. Sin players compete to survive by collecting resources, using their sin powers, and eliminating other players. But Sin players must watch out for the Veritas player, who will try to convert them into fellow allies. The twist: players can lie about what sins they possess. A player literally calls "FN BS" when he or she thinks someone is lying.

It takes 5 minutes to learn, 20 minutes to play, and made for 2-6 players.
