Gameplay
Deadly Premonition is a survival horror game set in an open world environment and played from an over-the shoulder third-person perspective. The game's objective is to guide the player character, FBI Special Agent Francis York Morgan, as he investigates the identity of the Raincoat Killer, who is responsible for a murder in the rural town of Greenvale. York receives in-game money for numerous actions—both for finishing levels and for minor events, such as shaving or changing suits; he can also be fined for poor performance, such as wearing dirty clothes. Additionally, he requires food and sleep at regular intervals, as indicated by the gauges measuring his hunger and need for sleep. If his gauge for sleepiness reaches zero, he will become hungry more quickly; if his gauge for hunger depletes, he will begin to lose health. Sleeping restores his health and tiredness, while food and items to ward off sleepiness, such as coffee, can be purchased from stores in Greenvale.
York may explore Greenvale on foot, by car, or by using a special item obtained by completing a sidequest. Cars must be maintained, as they consume fuel, which York must purchase, and accumulate damage that eventually renders them useless unless York pays for their repair. York often has a specific time frame for investigating sites and interviewing non-player characters; however, if he misses the timeslot, the player may simply try again during the next day without a penalty. Places of business and entertainment venues in Greenvale have specific hours of operation and must be visited at the proper time to make use of their services. Non-player characters also have their own specific routines and travel around town as they go about their business. It also features a dynamic weather system and day-night cycle which affects the responses of the non-player characters. If York engages one at the right place and time of day, he or she may offer him a side-quest to perform for additional rewards. In addition to side-quests, trading cards are scattered throughout the town, which the player can collect while exploring. York can also participate in mini-games, such as darts, racing through checkpoints, and fishing, and may accelerate the passing of time by smoking cigarettes.
Deadly Premonition contains several combat sequences, in which York encounters supernatural enemies while trapped in the Other World. York may battle them using melee weapons or firearms, or may choose to evade them by holding his breath. Melee weapons will eventually break with continued use, and York's pulse increases whenever he runs or holds his breath. Periodically, York encounters the Raincoat Killer, which will activate either a quick time event, a chase sequence, or a hiding event necessary to escape the murderer. During the Other World sequences, York's primary objective is to investigate crimes that took place there in the recent past. He collects photos of evidence to use to "profile" the scene and reconstruct events that took place with his deductive skills. Furthermore, the Other World regularly affects the entire town, excepting the interior of buildings, from midnight to six in the morning.
Plot
Francis York Morgan investigates the murder of 18-year-old Anna Graham (Melissa Hutchison) in the rural town of Greenvale, Washington, in the United States. He takes on the case due to the manner of the killing: a ritualistic murder of a young woman where red seeds have been found on or near the body, similar to a series of other murders across the United States. York generates considerable friction with his dismissive attitude toward the locals, bizarre demeanor, and tendency to interrupt conversations to deliver asides to an unseen person referred to as "Zach." He is assisted by the town's sheriff George Woodman (Casey Robertson), who is scarred by a past of childhood abuse; the deputy sheriff Emily Wyatt (Rebecca Wink), who becomes a love interest for York; and Thomas MacLaine (Christopher Sullivan), George's meek assistant. Additionally, York finds himself regularly ambushed and attacked by the Raincoat Killer, who, according to the folklore of the town, kills only when it rains.
As the investigation continues, Anna's close friend Becky Ames (Amy Provenzano) and Diane (Christiane Crawford), Becky's elder sister and art gallery owner, are murdered in a similar fashion, with a mark placed nearby that York believes to be a peace symbol upside-down. He learns that the trees producing the red seeds grow in Greenvale and that there are two Raincoat Killers. The original one, who inspired the folklore, went on a killing spree after the United States military released gas made from the red seeds into the town in 1956, causing the residents to temporarily experience an uncontrollable, murderous rage. The second, the New Raincoat Killer, hopes to gain immortality by consuming the red seeds and murdering four people, who have also been forced to eat the seeds.
