FNF Sonic Below The Depths


A FNF mod where you sing along with a new EXE sonic that due to an unfortunate series of event is chained to the underwater mine. Maybe a rap-battle will lessening his suffering.

This mod is the third song, called sink, in the trilogy of EXE Sonic mods. First being Chaos Nightmare, second being Phantom Attack.

Will someone be able to save him or will he be trapped forever?

Listen to the OST on the official composer’s YouTube channel.

Character origin story:

Chained for eternity, Sonic ponders…

“Sink is an “exe” who doesn’t fall under the typical standards an average exe comes down to. He’s not corrupted or possessed by some demon. He’s simply just a Sonic who got caught up in a series of unfortunate circumstances. Battered and bruised, got himself caught inside the chains of an underwater mine, trapped with no air in sight. He drowned and sunk to the bottom of the Labyrinth Zone. Due to his sheer will power, much to his dismay, he is able to somehow still ‘survive’. He’s essentially like a zombified sonic, trapped inside a never ending state of pain, suffering, and loneliness. He doesn’t know how long he’s been trapped down there, endlessly waiting for SOMETHING that can save him from his agony. Days, weeks, years, decades. All he can do is wait in pain…”
