The core game includes the base decks for both the prosecution and defense along with all the other components (jurors, bias tokens, etc) you need to play any case of Lawyer Up. The core set also features two unique cases to play: The Art Forgery Case and the Murder Case.
The Art Forgery Case is a shorter case (6 Witnesses instead of 9) that focuses on learning the arguments and procedures in the base Prosecution and Defense decks. It is all about drafting the paintings from famous Dutch painters and using the right evidence to replay them from discard piles.
The Murder Case is your modern Law and Order murder trial. Jessica Fairmount was found standing over her father, covered in his blood, but insists that she was only trying to save him. The wealthy socialite has a lot to gain with her father’s murder, but did she do it? This case features major asymmetry between the Prosecution (who can lock jurors to their side) and the Defense. The Prosecution must get all the Jurors to believe she is guilty while the Defense only needs one Juror to believe in her innocence for reasonable doubt.
