In Phoenix Wright, Ace Attorney: Justice for All, players take the role of a young defense attorney who must examine witnesses, investigate crime scenes, analyze testimonies, and collect evidence in hopes of obtaining a not guilty verdict. Phoenix is faced with four different cases including an introductory level where players are shown the ropes of the game. If stuck, Phoenix can call on Maya Fey and Pearl Fey, two psychics, for help. They offer leads and clues to get gamers back on track.

Additionally, gamers can use an item called the Magatama to see subjects or "Psyche-locks" a witness is not willing to talk about. Gathering enough evidence and presenting them to the person with the corresponding "Psyche-lock" will unlock these secrets and help the overall case. Players can also present profiles as evidence ultimately doubling the amount of facts Phoenix has against the prosecution. Though the game requires no shooting of any kind, Phoenix will eventually "die" if too many mistakes are made and his life bar is completely depleted. However, gamers can refill the life bar by accessing "Psyche-locks" and getting important information from witnesses. - Gracie Leach
