Michael's Tests are divided in seven parts: * The Revolver Trap * The Tank * The Crushing Table * The Elevator Trap * The Burning Rack * Campebell's Final Test (Path of Blood) * Michael's Final Test (Path of Flesh) Once Michael escapes, he finds himself uncovering a drug-ring conspiracy that is connected to his father Detective Tapp's death. After his first trial, Michael is equipped with a shotgun vest (similar in fashion to the Shotgun Collar from Saw III) that prevents him from wandering off of the designated path.
