Friday Night Funkin: The X Event Full Week

Boyfriend lands on a shadowy FNF stage packed with guests from the Undertale universe in Friday Night Funkin: The X Event Full Week. Gaster, Chara, and Ink Sans line up as opponents, and every track locks the screen into a dark, tense vibe that feels very different from the usual colorful weeks. Each song plays as a direct musical battle. Notes scroll in fixed patterns, and the game tracks every hit and miss, so focus matters on every beat. The mix of Friday Night Funkin's music style with Undertale-inspired characters gives this mod a very specific crossover feel that fans of both games notice right away.

How to play?

Start in Story Mode to follow the full week of songs in a preset order against Gaster and the other Undertale characters. Progress song by song, and keep the health bar from dropping by matching the arrows on time. Miss too many notes, and the current track ends, breaking the run.

Switch to Free Play when a particular track or rival feels more interesting. Pick a single song, select which opponent to face, and jump straight into a one-off music fight without replaying the whole week. Before every battle, set the difficulty to Easy, Normal, or Hard. Easy gives more room for mistakes, Normal tightens the timing, and Hard demands consistent accuracy. Test different tracks, learn their patterns, then raise the difficulty and see how long Boyfriend can hold the line against Gaster, Chara, and Ink Sans.
