The fourth part of the horror story is devoted to a sad incident called "Bite 87" and is a prequel to the previous series. The plot of the game should finally reveal all the secrets associated with the mysterious pizzeria "Freddy Fazbear Pizzia".

The protagonist of "FNaF 4" is not a security guard, but a small boy, terrified of animatronics. The action of the game takes place in the child's room, where every night, according to the usual pattern, it will be necessary to drive aggressive animatronics to live until morning.

This time the hero does not have to just sit still, looking through the surveillance cameras and waiting for his fate. Developers have added a new opportunity for the character - to move freely around the available territory. The fight with the mechanical dolls is to be done with a flashlight and doors. Since there are no surveillance cameras in the fourth part, the player will only have to rely on his hearing. Each animatronic produces its own unique sound. Only attentively listening to the tramping of steps, creaks and laughter behind the door, you can stop the evil creatures of hell. The lantern only helps detect the animatronics, but they no longer disappear from its light. The protagonist must constantly switch his attention between the bed, the closet and the door to survive.

After every night there is a small mini-game, telling the story of the main character. He is very afraid of mechanical dolls in a pizzeria, but his older brother ridicules this phobia, often hides in the child's room in an animatronic costume and scares the boy to tears. As the game progresses, new details of the protagonist's relationship with his brother will unfold, which will ultimately lead to terrible consequences.

"Five Nights at Freddy's 4" can be considered a worthy end to the series, with a chilling atmosphere of horror and helplessness, which is reinforced by the fact that the main character is a child. From a low-budget indie game with screamers, the project grew into a full-on horror film, which gathered a large army of fans.
