What is FNF vs Sonic.ERR (Tails) All About
Welcome this new antagonist from the Sonic world! He is none other than Tails, he is being featured in this new mod called FNF Sonic.ERR. This is another epic crossover that comes with just two original tracks: extinction and no-salvation.
Like all other episodes of FNF, your task in this one is to match each note of the tracks. When the arrows appear on your screen, hit the same key on your keyboard without wasting a second! Being in sync will turn the bar in your favor, which means that you have won the game. So all the best to you and have a great time playing!
