The game fully utilizes the Nintendo DS's unique dual screen allowing players to immerse themselves in the environments of New York. They will be able to reach into this world, move around, find clues at crime scenes, solve puzzles and answer questions. The innovative use of the Nintendo DS stylus will also allow you to trace marks, routes and memos on suspicious items discovered at crime scenes, all allowing you to move closer to solving the kidnapping mystery.
In addition to the on-going and developing kidnapping case, players also have to solve a series of eight independent cases. There are also five action games related to the kidnapping storyline to undertake.
