Players are dealt 4 cards. If you have any Crimefighter cards--Batman, Robin, Alfred the Butler, Commissioner Gorden, or Dr. Chase Meridian--you lay them face up in front of you. On your turn you draw a new card and play cards from your hand. Crimefighter cards are placed in front of you. The Riddler card steals a crime fighter from another player. A Bat-Signal card played with a Two-Face card starts a battle. Place the Two-Face card next to an opponent and flip the Battle Coin. If it lands on Two-Face, take a Crimefighter from the player. You may continue playing Two-Face cards on this opponent until you lose a battle (ending your turn). Playing a Batman and Robin card nullifies both Riddler and Two-Face cards. The first player to collect a complete set of Crimefighter cards wins. - BoardGameGeek
