Tails is the antagonist you are facing off against in the FNF Sonic.ERR mod, which is yet another crossover between these two series that everyone visiting our website knows and love, so once again let's have a ton of fun with a rhythm battle, this time on the following two original tracks:
- extinction
- no-salvation
Sonic.ERR and FNF present Tails, let's battle him!
In either mode, reach the end of the songs by playing all their notes according to the charts to win, something that you do by pressing arrow keys at the same time as the identical arrow symbols match above BF's head. Make sure not to miss hitting notes multiple times in a row, or you need to start again from scratch. Good luck and all the best we wish you all!
