Criminal Case casts players in the role of a new member of the police force who is tasked with solving a variety of brutal crimes. The first case acts as a tutorial, with the player being introduced to the various components of gameplay one by one, and then subsequent cases become increasingly lengthy and complex as the player progresses.
The game is split into several parts, each of which advance the plot of each case. Hidden object scenes are handled fairly traditionally — players are presented with a list of objects to find, some of which are key clues for the case, and must find them as quickly as possible to score maximum points. Upon completing a scene, the final score (plus time bonus and additional bonuses for any “hints” remaining) contributes to a cumulative star rating for the stage.
Unlike most hidden object games, however, these stars actually play a role in the game rather than simply showing your “mastery” level of a particular scene. Stars are used to unlock various additional investigation scenes, which vary from simple conversations with suspects to puzzles requiring the player to reassemble broken objects, find items hidden in piles of red herrings and decipher codes. Stars are expended upon performing these tasks, so the game does occasionally descend into grinding as the player tries to acquire additional stars to complete all the objectives. Criminal Case Hack
Alongside these interactive elements, certain items such as the victim’s body and other objects found at the scene must be sent to the lab for analysis, which takes a period of real time to complete. As ever, these real-time delays may be bypassed with the expenditure of hard currency.
