FNF Vs. Sans: Last Determined

Last Determined is a Friday Night Funkin’ Undertale crossover mod where Boyfriend goes head-to-head with Sans in a rhythm battle deep underground. The mod combines the musical gameplay of FNF with the mysterious atmosphere of Undertale.

While heading out on a date with Girlfriend, Boyfriend suddenly gets transported to a strange mountain by an unknown figure. Before he can even understand what’s happening, he finds himself in the Underground—a place filled with danger, mystery, and one very familiar skeleton.

Now Boyfriend must prove his determination through music as he faces Sans in a series of intense rap battles.
