So in Last Bullet we had Megalovania from Homestuck modded for us as a great menu song, and now fairly recent the pumping Megalovania from Undertale as a great assault track.
But then i thought to myself "Wait, Toby Fox also made the Halloween Hack for Earthbound, with the first Megalovania. Why can't we also have it modded too and then the trio will be complete?".

And then i did it;

Megalovania from The Halloween Hack replaces A Merry Payday Christmas (Vocal).

PREVIEW

Now everyone can enjoy the full extend of Megalovania with a triple dose of Megalovania! Megalovania love intensifies!

Just place it inside your mod_overrides folder!
Enjoy \o/
