SYNTECH is a Virtual Vocalist in the world of FNF, so, basically, he is a robot. He is a robot created with the purpose of defeating Boyfriend in a rhythm battle, but here you are to show that human rhythm can beat even algorithms, so let's defeat this new character right now on the following tracks:
Boyfriend Vs Syntech, an FNF battle of humans and robots!
Whether you are playing in the story mode or free play mode, reaching the end of the songs by playing your notes according to the charts is how you win in both instances.
This means that when you see arrow symbols match above BF's head, that is when you press the identical arrow keys to hit your notes.
Know that pressing the wrong keys or at the wrong time means missing a note, and missing multiple notes in a row leads to you losing. Good luck and all the best we want to wish you all!
