Justice for All picks up about a year after the original Ace Attorney, and Wright has a couple new tricks up his sleeve. The first is a health bar, which takes varying amounts of damage when you screw up in court. Second, you'll be able to present character profiles as evidence during questioning and cross-examination. Third, you can see through lies.
After reuniting with his psychic teenage sidekick, Maya Fey (and her seven-year-old cousin, Pearl), he's handed an item that enables him to see big red "Psyche-Locks" when people try to hide something during questioning. If you can find the right evidence to smash down your target's defenses, you'll eventually break the locks and get them to confess whatever they're hiding.
Sadly, you can't use that power in the courtroom, and showing the wrong evidence will damage your health. Nevertheless, it's a cool, tense little addition that adds a new dimension of weirdness to the gameplay.
