Police Activity: Cardboardman is a first-person slasher game where, in one segment, you play as a serial killer nicknamed "Cardboardman," and in the other, as a detective trying to catch him. Your objective is to locate a murder weapon and kill your victim. Staying undetected is crucial; the victim might kill you if they discover an intruder in their home, and accidental witnesses could call the police. The killer’s goal is to eliminate as many victims as possible, while the police officer’s task is to gather all the evidence needed to track down and arrest the killer—before the killer turns the tables and hunts him down.
