A HilariouslyBadFriday Night Funkin’ Experience

Get ready to groove through one of the most uniquely terrible mods in theFNFuniverse —FNF vsSonic.EXEbut Bad. This isn't your average rhythm game mod. It’s a chaotic, intentionally rough take on the already intenseSonic.EXEcollab, remixed with humor and some seriously questionable design choices.

Originally built as a joke, this version flips the script by making everything worse — or maybe even better? You be the judge! Whether you're here for the meme value, the absurdity, or just to see how far things can go off the rails, this mod delivers an unforgettable experience.

The mod keeps the classicFNF vs Sonic.EXEvibe but cranks up the chaos. Expect glitchy animations, wonky mechanics, and all-around bizarre behavior that leans fully into the"but bad" theme. It's not broken — it'sintentionallybroken.
