This is an action-horror game in which players assume the role of a detective investigating a series of strange murders in a small town. Players examine crime scenes, interview townspeople and suspects, and occasionally use guns, knives, and metal pipes to battle zombie-like creatures. One humanoid-like monster (naked, but with no genitalia or nipples) crawls along walls and can be killed by using a submachine gun. In one flashback sequence, players are able to control the villain (the Raincoat Killer) as he uses an axe to kill the townsfolk—toxic gas has left them in a deranged state; the grainy black-and-white sequence depicts the townsfolk emitting red blood-spurts when hit, as their bodies disappear.
Graphic depictions are presented during investigations of crime scenes, where players sometimes discover the victims: a woman is found tied to a tree with her abdomen sliced open—blood surrounds the open wound (hair partially obscures her breasts); another woman is strung up by wires in a shower, covered with blood, and strangled by an elaborate trap; and a "profile"-montage depicts still-frame images of a struggle between killer and victim amid sounds of crying and desperate pleas (e.g., "stop, please . . . I swear . . . I won't tell anyone . . ."). A couple of cutscenes are intense as well, depicting suicides via gunshots to the head. The dialogue contains mild sexual innuendo (e.g., a woman at a gas station says, "Let me know if you want me to pump it") and more direct commentary about sex: "She'll scr*w anyone" and "Oh, I sleep with anyone I wish. Anyone I prefer to sleep with . . . I could sleep with you, if you'd like."
