We will see Sonic, one of Japan is national series characters, in Fnf and we will try to defeat him in Fnf. I hope you are experienced with other Fnf games. Otherwise, Sonic is a very fast character and you have to use all 10 fingers to race against him. You can use the arrow keys against Sonic. Fnf vs. I wish lots of fun and good luck to all players in Sonic.exe game. Fnf Mods
