FNF Insanity Unleashed vs Insanity Sans

Plays: 3

FNF Insanity Unleashed vs Insanity Sans is an FNF mod where you play as Boyfriend, who finds himself in the world of Undertale. Today, he faces brutal battles against Sans in three of his forms. Find the craziest version of the skeleton by trying to defeat him in different forms to the beat of rhythmic melodies. Play your notes correctly so you don’t lose your streak from verse to verse and can hold out until the end of the battle.

Select a music week from the Story Mode menu. When the battle begins, focus on the right side of the screen. When the symbols align with their corresponding cursors, press your keys without missing a beat. If you make too many mistakes, the battle will end. Try not to miss notes too often, keeping up with their tempo even during the most intense moments. Stay focused and make it to the end so you don’t have to replay the battle, earning a higher success score.

  • Insanity
  • Bloodshed
