FNF: Phantom Attack – Tails VS. Lord X

A High-Stakes Rhythm Battle Awaits

InFriday Night Funkin’: Phantom Attack, the skies darken as Tails comes face-to-face with the ominous Lord X. This fan-made mod delivers a thrilling one-on-one musical showdown set to the haunting track“Vessel”, where every note could mean victory—or defeat.

Originally created as a sequel toChaos Nightmare, this mod takes players back to Green Hill Zone, but not for a leisurely stroll. Tails is on a mission, and what he finds might just test his skills in ways he never expected.

Unique Gameplay Mechanic

This mod introduces a fresh twist to the classicFNFformula:letter-based note inputs. As you play, letters will appear on your notes, and you must press the corresponding key on your keyboard. One wrong move—and it’s a steep health penalty. It’s a true test of reflexes and accuracy, perfect for rhythm game veterans looking for a challenge.

The Track:"Vessel"

The entire mod centers around a single, intense song:“Vessel”. Composed by Biddle3, the track sets a dark, atmospheric tone that matches the high-tension battle between Tails and Lord X. If you want to get a feel for the music before jumping in, be sure to check out the composer's YouTube channel for the full soundtrack experience.
