Five Nights at Freddy's 4 is a very frightening and scary adventure game, the game inherits the gameplay of the second and third part. The character-derived TV show that appears in the passing levels confirms that the story is set around 1983, and the updated scenes show items such as pumpkin lanterns, spider webs and bats. On the other hand, these levels also fully demonstrate only slightly mentioned in the second "Fred Bear's family restaurant", while officially acquiescing to the first three known Golden Freddy, the same as the first real Fred Bear in this game.

And with the information of the first three games, we can learn that this character and Spring Bonnie as described in the third game, which is a period of time with four mechanical dolls characters - Freddy Fazbear, Bonnie the Bunny, Chica the Chicken and the Foxy the Pirate Fox for the same scene promotion. However, after the accident in the main line of this work, Freddy Bear seems to be rightfully deprived of the leading role, and because of the problems mentioned in the third work and at the same time spring Bonnie discontinued, the achievement of the second work in the repackaging image of Freddy Fazbear's Pizza.

In addition, the housing of the passing level appears Mangle the Fox, with the scene of once being locked in a suspected parts/service room, which is very likely to bring out the player character and restaurant operators have a close relationship.
