Garcello has returned to get payback, and not only did he bring along a new song, but also friends from FNF that he thinks can help him defeat BF, something that you won't let happens right now on any of these following songs:
Help BF survive Garcello's Return to FNF!
Whether you are playing in the story mode or free play mode, to win you do the same thing, which is hit your notes according to the charts until the songs conclude, which is when you win.
Press the arrow keys at the same time as the identical arrow symbols match above BF's head to hit your notes, but missing to do that multiple times in a row leads to you losing, so do not let it happen. Good luck, enjoy!
