Apollo Justice: Ace Attorney is the fourth game in the Ace Attorney series. It was releases for the Nintendo DS in 2008, and a mobile release is planned for the end of the year.

This is not only the first game in the series to be entirely developed for the DS, it's also the first game in the series to focus on a new protagonist. Set seven years after the third game, Apollo Justice is a new attorney on the scene. He finds out that famed attorney Phoenix Wright has become disgraced and disbarred, and begins to investigate what happened.

There are a total of four cases in the game, which are as follows:

1) Turnabout Trump -- Apollo's first case as an attorney, he soon finds out that his mentor, Kristoph Gavin, is notwho he seems. At the end of the story, Phoenix invites Apollo to start working out of his old law offices.

2) Turnabout Corner -- After accepting Phoenix's offer, Apollo is sent to investigate three crime scenes which may or may not be connected. This case introduces Ema Skye, a forensic specialist who helps you test things for things like fingerprints and blood.

3) Turnabout Serenade -- Prosecutor Klavier Gavin -- brother of Kristoph Gavin, Apollo's former mentor -- invites everyone to his concert, where things quickly turn south. A female musician is accused of murdering her manager, and Apollo takes the case.

4) Turnabout Succession -- This is the case where we finally learn about the supposedly falsified evidence that got Phoenix thrown out of court years ago. It also involves a family member of Apollo's.

I would probably put this a step up from the second game in the series. There are a few new gameplay elements here, including the ability to spot when someone is lying, which I think is quite neat. Very often in life, whenever we lie, we have a subconscious "tell" which reveals that we aren't telling the truth. This played on that quite well.

Still, I felt the cases could have been stronger. They're still lacking in comparison to some of the other games in the series. Part of this could have been the absence of such beloved characters, but part of it is definitely just the writing.
