Place this clip just before the visual reveal of the ambush, then pair it with a sharper payoff like the fnaf jumpscare scream for the hit itself. For a funnier cut, follow it with the enemy spotted sound effect to pretend the warning finally registered.
Über diesen Sound
This is a 4.5-second Spanish voice line, "Detras de ti, imbecil," shouted in a taunting tone by a Ganado enemy. Listeners get a jolt of tension mixed with dark humor, because the warning arrives as the threat is already behind you. It comes from Resident Evil 4, where the line plays as Leon is about to be ambushed.
