The update adds a secret ending. If you collect 5 "Remnant Orbs" and offer them to a broken Toy Freddy statue in Level 194 (The Poolrooms), you unlock the "Witness" ending.
The updates have introduced a unique "affection level" for certain entities, suggesting branching paths or social mechanics alongside the horror.
True to the "Survival" moniker, the update often introduces limited resources.

The resources are scarce, forcing players to make strategic decisions about when to run and when to hide in the endless closets or behind false walls.
