Namco Bandai Games launched a 15th anniversary website for its Digimon games on Tuesday and revealed that a Digimon Crusaders card role-playing game will arrive on the iPhone this Fall. With the app's simple touch controls, the player can select cards for battles. Three cards of the same color will enable a Digimon of that color to attack enemies. Three cards of the same type can also unleash a chain attack for massive damage. (Digimon, Digimon Crusader, Gaming)
