Yes, FNAA 3.0 is Canon, version 3.0 will be a sequel to FNAA 2.0.

FNAA 2.0 takes place in 1996, version 3.0 will take place in September 1997, basically Fazhuman Entertainment opened a new location, with new versions of Angel and Jake and new animatronics, Eddie and Marvin,

But in this new and improved restaurant, strange things keep happening.

I wanted to make this clear, so you know that version 3.0 will not be just an update
