Place this clip at the start of a power-up sequence in your edit, let the scene play out, then follow it with the fnaf jumpscare scream for the payoff. For a build-up, layer the danger alarm meme sound button underneath before it starts.
About this sound
This clip is a short laser power-up effect linked to Sonic.exe, lasting just over two seconds with a sharp electronic charge building into an active beam sound. It feels tense and unsettling, giving a normal moment a sudden horror-game edge. The sound comes from the Sonic.exe creepypasta horror game world referenced by fans as the spirits of hell sequence.
