Perfect Crime

Perfect Crime is a detective game built around the logic of criminal investigations rather than conventional jigsaw puzzles or mini-games. You plan murders, create alibis and try to prevent the police from uncovering the truth. You can also use the case editor to create cases of your own and play cases made by other players.

Crime and investigation

Each case has two parts. During the crime, you choose a method, plan when and where to act, create an alibi, prepare the weapon and remove evidence from the scene. You must account for the timing of other characters’ actions as you make your plan.

During the investigation, the police assess suspects based on evidence, alibis and the places they regularly visit. Each aspect affects suspicion: lacking an alibi can make suspicion rise rapidly, while a carefully planned crime may leave the police unable to identify the murderer.

Evidence and suspects

Your actions can leave traces. Calling someone, visiting a house or touching an object may provide evidence, and choking a victim can leave scratches on your arms from their struggle. Tools such as keys, cups and daggers each have their own functions, but using them carelessly can draw attention. For example, someone in the room may notice if you pick up a knife without first distracting them.

Characters have different personalities and respond differently to the same events. If someone finds a body, they may call the police immediately or investigate it themselves, leaving traces behind. Dangerous actions such as choking someone or tying them up also create psychological pressure; if it becomes too high, you cannot carry out the action, so you need to manage it using skills.

Creating an alibi

Alibis depend on witnesses. If a character sees you enter a restaurant at 8 o’clock and leave at 9, they can confirm you were there during that hour. If the murder takes place at the victim’s house at 8:30, that testimony can provide an alibi. Since you always play the murderer, every alibi is false; you must find ways to create one, as having an alibi lowers your suspicion.

Create and play cases

The case editor lets you create your own cases. You can also access cases made by other players, play them and upload your own cases to Steam Workshop for release as mods.
