Experiment: deal with the demon

A murder has occurred in our psychiatric hospital, where the head doctor was conducting experiments on people, studying schizophrenia. The patients and staff of the hospital have been relocated to another building, as an investigation is still ongoing at the hospital. The police have not provided any comments. Rumors suggest that something mystical is involved. You, a group of paranormal phenomena researchers, are sneaking into the closed hospital to investigate the crime scene.
