Friday Night Funkin': Vs. Sonic.EXE is a mod directed by MarStarBro, Comgaming_Nz, and Averyavary under the ownership of RightBurstUltra. The main opponent of the mod is the titular character from the Sonic.EXE creepypasta , but it also features many other horror-oriented characters from other official and fan-made Sonic media, including Sonic (PC PORT), Sonic CD, Sunky.MPEG, Sonic R, and Sonic the Comic.
There are quite a few secret Friday Night Funkin Sonic Exe Sound Test Codes. But first, you need to beat Sonic in the first song and only then you can get access to the other songs.
