FNF vs Opponent Onslaught

A mod of Friday Night Funkin where Boyfriend rhythm-battle against some similar faces such as Whitty, Red & green Impostor, Beepie, Senpai, Miku, and Majin Sonic, after a portal appear in the middle of the street.


A mysterious force is causing reality to unravel, opening up portals from which familiar faces are emerging around the city!

They all seem to be targeting Boyfriend, who is fighting back the only way he can: tight bars. Despite not understanding anything going on, it’s up to BF and GF to find the source of the anomaly and put a stop to it!
Get ready for an onslaught!
