FNF vs KOU (Kepler Observation Unit) v3

KOU, the Kepler Observation Unit of FNF is back with a V3 of their mod, where you are about to once again have tons of fun from start to finish by going up against this chibi anime characters, and this is something that you do right now on an updated list of tracks:

  • Space Boy
  • Cosmic
  • K.O.U
  • Twinkle
  • Lockdown
  • Quasar

BF VS KOU, round 3, let's begin!

Watch as the arrow symbols float and match above BF's head, and press the identical arrow keys at the same time, something you need to keep on doing. Be careful not to miss hitting said notes multiple notes in a row, or you need to start again from scratch. Do this in either the story mode or free play mode, giving your best in both! Enjoy!
