Unsolved Crimes places you in the role of an unnamed detective working the homicide division. You are partnered with a young detective named Marcy and together, you'll work several cases and withstand the verbal assaults of Captain Abbot. Cases range from simple stabbings and shootings to a string of bloody axe murders - so you have your work cut out for you.
Each case begins the same way: Abbot gives you a briefing on what is already known about the case and then sends you and Marcy to the scene. Once there, you are given addition information about the crime, such as witness statements and even a few alibis from suspects. From there, you can sift through the crime scene, collect evidence that may have been overlooked and start to piece together the facts.
Each of the eight cases is tied together by an ongoing subplot involving a kidnapping. While there's a bit of a mystery to be unraveled, the subplot introduces a few side games to the mix. One area places you in a shootout where you tap enemies with the stylus to shoot and another puts you in a high-speed chase. These segments feel a bit out of place when taken alongside the core gameplay and add little to the overall experience.
