sentences:  The game employed a well-designed, yet simple, concept of a player's team of X-Men attempting to defeat, or KO, two of four selected X-Men villains before the opponent did the same.Alternatively, a player could win the game if their opponent's team was knocked out before their own.Each X-Men character card was assigned a point value based on its mutant power (a special ability printed on the card that had an effect on game play, such as allowing the user to draw extra cards or deal additional damage to enemies), hit points (the amount of damage necessary to KO the character), and its ratings in each of three abilities (red-fighting, green-energy, and blue-X factor).
