Black Orchestra begins with each player choosing a historic figure involved in the conspiracy against Hitler. In this dark and dangerous pursuit, motivation is perhaps your greatest weapon. If you can stay true to your convictions in the face of overwhelming threat and inspire your comrades, then you will be able to use your special ability, attempt plots, and even become zealous (necessary for some extremely daring plots).
To win, players must collect a plot card and fulfill all necessary requirements listed (such as having Hitler be in a certain space and possessing certain items--detonator & fuse, etc.). The active player may then attempt the plot by rolling the indicated dice, including all additional modifiers and helpful Action cards. The total of number of "Target" symbols needed to kill Hitler is based on Hitler's military support, but a Conspirator's security level decides if any "Eagles" rolled will see them detected, and foil the plot regardless. Players must consider their ability to successfully complete a plot and the relative suspicion levels of the different Conspirators involved.
Players will need to work together and agree on the wisest course of action, as well as have a little luck, to succeed. The phenomenon of one player dominating the game because of its cooperative nature is mitigated by the fact that there are no certainties, and often a player will need to make a bold or reckless move to keep the conspiracy alive. Cool heads often prevail, but play it too cool and you may miss your chance. The co-operative dynamic gets really interesting if a player is ever arrested, and fails to resist interrogation, then they will need to make a big decision all by themselves, without revealing their options to the group. No one player can guarantee success. It is hoped that players will have tense conversations similar to those had by the real conspirators and enjoy a truly unique historical experience.
