This game was attached to the ioGioco #21 magazine. You are late. Damn if you're late! The Judge will not take it well. But it's not your fault, really! Your colleague, Turk, the one following the case, had a kind of nervous breakdown and left the office suddenly. Now you are here running up the courthouse stairs, dodging the crowds and desperately scrolling through the papers of the first hearing. Because there has already been a first hearing but you haven't read all the papers yet ... and you have to face a murder trial! Fino a Prova Contraria is a new cooperative game system that can also be played solo. As a lawyer, the game will see you face a sequence of accusations: in each of them the Attorney will try to prove the guilt of your client. The focal point of each intervention will be highlighted in bold: to it, you will have to respond with a Defense among those available to you, or using evidence or testimony that contradicts the statements of the Prosecutor. As you try to draft a defense, you will discover more and more details that will allow you to investigate the murder that took place. The title of this first chapter is Omicidio color zaffiro.
