FNF: Starlight Mayhem (Vs. CJ)
FNF: Starlight Mayhem (Vs. CJ) is a Friday Night Funkin' mod with a concert stage and its own combo meter.
CJ plays like someone with something to prove, and this mod gives him a proper venue to prove it in. This is the Rebooted build, with recharted songs and a new mechanic called BURST.
How to Play FNF: Starlight Mayhem (Vs. CJ)?
Arrows scroll up the screen in four lanes and you press the matching key as each one reaches the top row. Hit them and the health bar leans your way. Stack up misses and it tips to your opponent and the song ends early.
Story mode opens with Focus, then runs Inverted Ascension, Echoes and Artificial Lust, with a difficulty picker before you start. Free Play holds four more: Parallax, Starstorm, Coda and It's Complicated. The big addition is BURST, a meter on the right that fills as your combo climbs. Spend it with Space to double your score and regenerate health. Ruby turns up as a second opponent too.
Tips and Tricks:
- Build your combo: BURST only fills while you keep hitting notes.
- Spend BURST when hurting: It regenerates health as well as doubling your score.
- Pick the difficulty per song: Each song has its own Easy, Normal and Hard.
