FNF vs Cassandra SIGMA


A mod of Friday Night Funkin where Boyfriend rhythm-battle against Cassandra in the Sigma edition with vocal, chart, dialogue, and songs had been slightly changed from the original.


  • Berzerker
  • Possession
  • Takeover
  • Daddy-Issue


After the events of Pico’s past revolving around the school, the evil rival to Pico strikes back again from the dead years later with a brand new look! Instead, she’s going after our favorite blue-haired rapper for dating her sister, Girlfriend. Apparently Cassandra had some pass beef with her, but luckily, instead of a cruel interaction, Cassandra learns to behave herself, attempting to become better equipped for society with the help from BF and GF!
