The FNAF franchise has undergone significant changes since its inception. The first game introduced players to the concept of survival horror, where players took on the role of a security guard tasked with monitoring a haunted children's restaurant. As the series progressed, the gameplay mechanics and storyline evolved, incorporating new animatronics, environments, and plot twists. Security Breach represents a significant leap forward in the series, offering a more immersive experience with its expansive environment and diverse animatronic cast.
