Trials are an important gameplay element in Professor Layton vs. Phoenix Wright: Ace Attorney. They are based on the trials from the Ace Attorney series. The ultimate goal of a trial is to find out the truth behind a set of events.
During the trial, various witnesses are called forth one at a time to testify about what they witnessed. Phoenix Wright can then cross-examine these testimonies to find out if there are any contradictions with the evidence. If not enough information is present in the testimony, it is possible to press the witness to add more details. Once the contradiction has been found, Phoenix can present his evidence with an Objection.
Witch trial Edit
Witch trials (also called "group trials") are a special kind of trial that have some differences with the classic trials. They are unique to Professor Layton vs. Phoenix Wright: Ace Attorney and do not appear in other games of the Ace Attorney series. The goal of these trials is to defend Espella (and others) from being convicted of witchcraft.
Unlike in a normal trial, no witnesses are called forth, and no cross-examinations happen. Instead, any person in the courtroom can give a testimony whenever they see fit. As a result, there can be many witnesses at the same time. It is essential that you compare the testimonies of the people to find the contradictions. You can also check for changes to the other witnesses to see if they react to the testimonies of others.
Overall, the witch trials are more chaotic, which is used to emulate a possible trial from the Middle Ages.
