A Hellish Rhythm Battle Awaits

InFNFvs Grandpa Grandest,Boyfriendfaces one of his most intimidating opponents yet — his ownGirlfriend’s grandfather — in a high-stakes rap battle deep within the depths of hell. This mod takes players on a dark, intense journey through three brand-new songs, all wrapped in a fiery, apocalyptic aesthetic. With devilish dancers, haunting visuals, and increasingly difficult charting, this mod delivers a true test of skill for any Friday Night Funkin’ veteran.

Originally plagued by performance issues, the mod was updated on June 22, 2024, to fix freezing and other technical problems — making it smoother and more enjoyable than ever before.

Tracklist: Face the Fire

Dive into the inferno with these three custom songs, each designed to push your rhythm skills to the limit:

  • Dad battle– A heated start to the showdown, setting the tone for what’s to come.
  • Reaper Rhythm– The intensity rises as you go head-to-head with death itself.
  • Behold The Apocalypse– The final challenge, where the world ends in beat-dropping fashion.

Each track features unique animations, themed backgrounds, and progressively difficult note charts that make this mod both a visual and mechanical spectacle.

What Makes This Mod Special?

While many FNF mods follow familiar storylines,Grandpa Grandestdares to be different. The mod flips the script by pitting Boyfriend against a supernatural force — a grizzled, otherworldly figure who doesn’t play by normal rules. The mod’s hellish atmosphere, complete with demonic imagery and fiery backdrops, immerses players in a world far removed from the usual rooftops and cityscapes of the base game.

This mod is perfect for those looking to spice up their FNF experience with something a little darker, a little stranger, and a lot more intense.
