About FNF vs Byron the Mafia Boss


Byron is a robot in a pinstripe suit, and this is because he is more than a robot, as he is also a mafia boss, just as the title of this brand new FNF mod suggests, with you having to help Boyfriend defeat him so that he can release Girlfriend from the mafia, with you having the chance to enjoy four awesome custom songs in this mod:

  • Vocalizer
  • Bitcrush
  • Hassle
  • Dishonored

Defeat the robot gangster with your amazing rhythm skills!

You can face against this character in either the story mode or the free play mode, it is your choice, but you have the same goal either way, which is reaching the end of the songs by playing their notes according to their charts.

To do this, watch for when arrow symbols above BF match with one another and keep pressing them at the right time because if you miss pressing the keys too many times in a row, you also lose the game. Enjoy!
