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).
But every move you make may also increase the suspicion of the authorities. The Gestapo will make routine sweeps, and any players with high suspicion will be arrested and interrogated (possibly resulting in other players being arrested). If you are all arrested or if the Gestapo finds your secret papers, you lose. And the suspicion placed on each conspirator will increase the chances their plots are detected.
