The Return to Freddy's 2 (Final Alpha Test) is the last Alpha Version of The Return To Freddy's 2. It isn't much different from its predecessor, The Return to Freddy's 2 (Alpha Test). Like the previous Alpha Test, and all things made before it, the character models are taken from the actual Five Nights at Freddy's Games. It has the same amount of cameras, similar building, and is still small and hard to beat. However, this game featured the add in of a music Box to keep the Puppet at bay. It brings back returning mechanics, the flashlight, power limitation, toxic meter, the Freddy Head, and the music box to stop The Puppet. There's also the Cupcake on the desk, the same Cupcake from FNaF 2. Like its predecessor, it was dumped for The Return To Freddy's 2.
Little is known. We know it was decided to change one of the cameras and add in the puppet and his music box, but other then this we don't know much. Later, it was most likely scrapped for its lack of quality.
