🎮 FNF vs Byron the Mafia Boss

Byron is a robot who wears a pinstripe suit and a hat, and, yes, he is the mafia boss in town, a mafia boss who kidnapped Boyfriend to force him to duel him in a rap battle, so now you will help our protagonist win and release his GF, doing it on the following four songs:

  • Vocalizer
  • Bitcrush
  • Hassle
  • Dishonored

Show Byron that humans sing better than robots, even mafia ones!

Whether you are playing in the story mode or free play mode, you’ve got the same goal of reaching the end of the songs and playing all their notes according to the charts, until you win.

Now, when arrow symbols match above BF, make sure to press the same arrow keys, and keep doing it until the end of the song.

If you miss pressing the keys too many times in a row, you lose the whole game and have to start it again. Enjoy!
