Place this clip at the start of the confrontation segment, after a Metal Gear Solid Alert sting to signal danger, then follow it with a Minecraft Damage hit each time your character takes a blow during the fight sequence.
About this sound
An instrumental excerpt from the opening thirty seconds of Megalovania, built on a driving synth bassline, sharp drums and a repeating lead melody with no vocals. It feels intense and confrontational, turning a small moment into a final showdown. The clip comes from the Undertale original soundtrack, where it is track 100.
