There are three adventures of the 'point and click' style. In each the player examines clues, solves puzzles, collects parts for a gadget and help people. As a reward the plate gets to ask key characters a question that helps to identify a suspect, this part of the game is played in the same way as the player vs computer game and uses the same character set.
