๐ŸŽฎ FNF vs Detras Mental Decimation

Detra is the newest character that you and BF will have to face off against in a musical battle, although that is not as easy as it sounds, because we’re talking about a character whose mind has splintered into different personalities, all of which you will face off against, and you do it in no less than seven awesome songs:

  • Retricus
  • Covetous
  • Terminus
  • Embark
  • Facade
  • Compel

Fix Detra’s mind by defeating him in a rap battle!

You can choose to face this new challenger in either the story mode or the free play mode, but no matter what you pick, the goal remains the same, which is to reach the end of the songs by playing all their notes according to the charts.

Look for when arrow symbols above BF’s head match one another, and keep pressing the same keys, but if you make a mistake once too many times, you will lose and have to start again. We wish you good luck, all the best, and invite you to stick around for more fun to come!
