Although Security Breach has a satisfying ending that could symbolize the franchise's end, I struggle to believe it would be. There have already been rumours circulating of a second Security Breach-inspired FNaF title, and with the incredible popularity of the series, I don’t think Cawthon is finished just yet. Furthermore, Security Breach leaves the doors open for future games, as most previous releases did, so I believe Cawthon likes to keep his options open.
