Friday Night Funkin: The X Event Full Week

Full Undertale AU Crossover Inside Friday Night Funkin’

Friday Night Funkin: The X Event Full Week throws players into a massive crossover inspired by XTale and Underverse, bringing X!Chara, Ink!Sans, and XGaster directly into FNF battles. Enter Week X now!

The Gameplay Changes More Than Just Music

The mod keeps classic FNF controls using WASD or Arrow Keys, but adds a custom RPG overworld inspired by Undertale exploration. Before entering battles, players can move Boyfriend around the map like a small story-driven adventure game. During Overwrite, gameplay itself becomes unstable as X!Chara interferes with the health bar and rhythm mechanics.

Characters, Songs, And Hidden Lore

Overwrite introduces X!Chara with aggressive reality-warping effects, while Inkingmistake and Relighted escalate the atmosphere with heavier visuals and faster charts. Hidden details also appear throughout the mod, especially around XGaster. Some players discovered Wingdings messages asking, “You think you are in control?”, turning the mod into a fourth-wall-breaking experience instead of a normal rhythm battle.

• Became one of the most downloaded “Golden Age” FNF full weeks
