While the series of update patches (to introduce a quantity of bug fixes, adjustments and optimizations, cut content resurrections, etc.) are currently under development to help improve the majority of the game, [1] [2] some DLCs were officially considered as confirmed by Steel Wool from Dawko's interview. [3] On May 30, 2022, a free DLC titled Ruin was announced, set to release in 2023.

On November 17, 2020, Scott Cawthon made an announcement stating that, due to the size of the game being much bigger than expected coupled with the complications of having to work from home during the COVID-19 pandemic, the game was being delayed from a pre-Christmas release until early 2021. [7] It was later revealed that "PizzaPlex" was part of the name of the main building in which the game takes place. Most of the locations and structures in the Freddy Fazbear's Mega Pizzaplex were actually based on places that the developers spent in their childhood. [14]Candy Cadet can be found in the room above and close to where the Mimic resides and by using the Faz-Tokens found throughout the game, he will tell a story about a mother, her son, and a monster that lived in a cabin out in the woods, telling the story of Ruin. On May 19, 2023, a gameplay trailer for the Ruin DLC was posted on Steel Wool's YouTube channel, with a release date expected to be within the month of July. [10]

It is implied that the mother is Gregory, the son is Cassie, and the monster is the Mimic in this story. Both Gregory and Twisted Alice caused the drop after speaking to the main characters via speaker systems. The only difference is that Gregory was forced to drop the elevator to prevent the Mimic's escape while Twisted Alice intentionally dropped it because unlike Gregory, she is a villain and wants to get her hands on Buddy Boris, who is in the elevator with Henry. Gregory did not continue talking after dropping the elevator. Roxy is still shown to have a grudge against Gregory for stealing her eyes, but when Cassie begs for her to let her go, Roxy realizes her mistake and apologizing.It is the first game in the franchise where the human models (Vanessa and Gregory only) are fully modelled and visible. The physical release for PlayStation 4 and PlayStation 5 was released on April 1, 2022, along with the game releasing on Epic Games Store. Although it is currently unknown what year this game takes place in the timeline, the month is shown to be March. [15] It is implied that Roxy was the only one who was present during Cassie's birthday there and remembers a majority of the details: It is implied that Gregory may have been the first and only friend Cassie had made while at the Pizzaplex, since none of the friends she invited showed up to her birthday party, also signifying their friendship and why Cassie went to the ruined Pizzaplex to begin with.

The Faz-Wrench that Cassie utilizes is stated by her to be just like the one her dad has, implying that her father is a repairman.However a new S.T.A.F.F. Bot named " Mask Bot" appears in the beginning of the DLC, which could be a new version of Map Bot. Depending on the player's choices, the duo then proceed to defeat a number of animatronics, including DJ Music Man and two of Freddy's three band-mates before the night ends at 6 AM. Gregory uses the parts obtained from Freddy's bandmates to upgrade Freddy in the Parts and Services workshop. Gregory can stay after 6 AM to defeat the remaining band member and/or get other endings, but only one save point, located in the second floor of the Atrium by the elevators, will work.
