FNF vs Bob Mod is an exciting music arcade game in which you need to compete with Bob in note-hitting battles to find a person getting the higher score.
In this game, your task is to control the Boyfriend character to hit the notes in the correct sequence of the song. Use arrow keys to hit. Note that there are arrows extending at the tail end. When you encounter such arrows, you need to press and hold the arrow until the musical arrow passes. Like the rules of the other FNF versions, you have to miss too many notes if you don't want to lose.
Bob is a cartoon character with a white body. In a chance encounter, he challenged the Boyfriend and the musical war between Bob and Boyfriend began.
There are two modes: Story Mode and Free Play. In Story Mode, you can choose between Bob Week and Bob's Onslaught. Free Play mode gives you more options.
