Topper the Copper casts you as an unusual law enforcer shaped like a top hat on the trail of a criminal. Inside a multi-level building connected by corridors and a lift, you search numerous rooms for vital clues. Safes may contain the evidence you need – eight clues are required to identify the culprit among seven suspects. One safe also hides the key to the jail. Meanwhile, enemies and obstacles stand in your way – every hit drains part of your energy, which can only be restored at the police station. If time runs out or your energy is completely depleted, the mission fails – only persistence and awareness will see justice served.
