Meitantei Evangelion (名探偵エヴァンゲリオン), translated as "Detective Evangelion", is an adventure/strategy game developed by BROCCOLI and written by Masaki Hiramatsu for the PlayStation 2. The story follows Shinji Ikari, a detective hired by NERV, as he attempts to uncover the truths behind a series of murders.
Much of the game is played in a visual novel-style format, where the story is told mostly through text, voice overs, and still images. There are, however, some points where the game changes to a 3D, third-person battle format. All of the main voice actors return to play their respective characters in the game. There are a variety of characters that were also designed specifically for this game to fill roles like teachers and students to either be victims or witnesses to a crime to help Shinji and the others make his case.
