Vs. Proto BF Title Screen

The mod plays with the idea of a"prototype" universe — one that feels eerily familiar to the earliest conceptual art of the original Friday Night Funkin’. As the story unfolds, players battle through increasingly intense beats to uncover the mystery behind this strange world and how our heroes ended up there.

Story & Gameplay

A Fight Through Forgotten Code

The adventure begins when Boyfriend and Girlfriend are mysteriously transported into a half-finished realm. Here, they encounter Proto BF — a glitchy, incomplete version of Boyfriend from a forgotten timeline. What follows is a high-stakes rap battle as they attempt to piece together the truth behind their sudden arrival.

Each song represents a different stage in the development of this prototype world, increasing in difficulty and intensity. The final track, in particular, offers a climactic showdown that tests both rhythm and reflexes.

Tracklist

  1. Ease– A calm beginning to a chaotic encounter. Lull your guard down at your own risk.
  2. Testing– Things start getting real as the prototype shows signs of life.
  3. Ridged– Jagged beats and glitchy visuals raise the stakes.
  4. Finalization– The ultimate showdown. Can you master the final form?
