Highlander: The Card Game is a collectible card game based on the Highlander franchise of films and television series. Players build decks from a 400+ card set, taking on the persona of one of the Immortals depicted in the franchise. The core of the game takes the form of a sword duel with players alternately playing attacks and defenses. Other cards are played to affect the basic rules of the game. You win when your opponent is reduced to 0 ability or cannot avoid a "headshot" attack.
