Gyakuten Kenji 2/Walkthrough

As you may have come to expect from the Ace Attorney series, you don't need any knowledge of the justice system or investigation procedures to be able to play this game. You have to find the culprits behind each murder through investigations, confrontations with other characters, and plain old logic. There will usually be an innocent bystander being blamed for the crime, so you must prove their innocence and find the real killer. If you make too many mistakes, the wrong person will be detained, thus resulting in a Game Over.

It's a good idea to read through the Getting Started, Controls and even the Characters pages before starting.
