Judging by the subtitle of the fourth FNaF game, it clearly implies that it will be the last game in the series.However, many horror franchises have had subtitles that made it sound as if they are the final installment, but then the series continued. The specific thing that makes me think that a FNaF 5 will be a thing at some point is the wording of the description of Five Nights at Freddy’s 4 on Steam which states, “In this last chapter of the Five Nights at Freddy’s original story…”
The phrasing of “original story” seems very deliberate. What I take this as is that after the DLC on Halloween, which I believe will be an extra gameplay mode and nothing story related, a new game storyline will be used for a new series of FNaF games. The 4 games to be released in the series thus far seem to be surrounded by the Bite of ’87 event. In the potential upcoming games, they will most likely expand upon the lore and center around a different horrible event that occurred within the Fazbear restaurants.
Even if I’m wrong, and Scott Cawthon never makes another sequel, there is still a movie being made that is currently being written. The director of the movie, Gil Kenan, has been very open about his process on twitter and has slowly revealed some tidbits about the movie. He has been hinting that the movie will not be a straight adaption of any one of the games in the series. Instead, the movie will be a separate event in the series that will be cannon within the universe of the games. Kenan seems to be loving what he’s doing on the movie and also seems to be just as excited as us fans are about the future of the franchise.
With the movie on the way, the franchise is far from over. Personally, I believe a fifth game will also be released at some point within the next year. Until then, we can always look forward to MatPat’s next Game Theory on the franchise.
