FNF vs Sonic.EXE 2/3.5/4

FNF vs Sonic.EXE 2/3.5/4 is a horror-themed mod for Friday Night Funkin’ where players face a corrupted and sinister version of Sonic the Hedgehog. This mod combines intense rhythm gameplay with a creepy atmosphere, making every rap battle feel tense and unpredictable.

The setting is dark and unsettling. You perform under a gloomy sky surrounded by disturbing visuals, including eerie references to Sonic’s world. While trying to hit notes accurately, players must stay focused as the background shifts and strange events unfold, making it harder to keep track of the rhythm.

This version of Sonic.EXE comes from internet creepypasta lore, originally inspired by a 2012 fan game. The mod stays true to that origin, recreating the horror vibe with retro-style menus that resemble old CD-ROM interfaces from the early internet era.
