A new sequel to Army of Two is in development, according to several internet reports. Despite the fact that the original Army of Two and its sequel received middling reviews and generated poor sales, a third game in the series is apparently on the card.
Little is known about the game other than the fact that it is to be called Army Of Four. Since the first two games stressed multiplayer action, we can probably assume that this title will do the same – except that four players will take part in the action instead of two.
