Apollo Justice: Ace Attorney (which takes place chronologically seven years after Phoenix Wright: Ace Attorney - Trials and Tribulations) is the first game in the series that does not feature Phoenix Wright as the main protagonist, though it isn't the first time a different attorney has been playable. The game takes place in what seems to be a mock of Los Angeles.
New gameplay elements
The bracelet on Apollo's left arm can be used to "zoom in on witnesses to gather information about them", and is called the Perceive System. It is used primarily in court to look for motions or actions made by witnesses that show nervousness, like playing with one's fingers. The move even comes with a new phrase, "Gotcha!". The game also includes a "Crime Recreation Mode" that "allows players to reveal hidden clues by re-creating the scene of the crime.
