FNF VS FNaF 1 is arguably the best Friday Night Funkin' mod among those inspired by the survival horror game series Five Nights at Freddy's. Based on Pouria_SFMs's previous work FNF VS Freddy Fazbear, it features 20+ songs, 15 pre-rendered cutscenes, unique note mechanics, and well-crafted 3D-ish sprites.
In this mod, Boyfriend and Girlfriend sneak into Freddy Fazbear's Pizza at night , and end up coming face to face with the restaurant's star attraction, Freddy Fazbear along with his three friends, and a rap battle is the only thing stopping the four murderous animatronics from killing Boyfriend.
Boyfriend is the protagonist of Friday Night Funkin'. Him and Girlfriend decided to sneak into Freddy Fazbear's Pizza late at night, leading to some unfriendly face offs with the animatronics inside.
Boyfriend's appearance is the exact same as the base game, but now he's three-dimensional to match the rest of the mod.
