Step 1.
Spawn in a Energy Vessel Explosive.
Step 2.
Activate it
Step 3.
Be ready to click "Clear everything" button
Step 4.
Click the button when right before the explosion actually explodes, There will be a small part where the audio cuts out.
And thats how you do it, Now the sound in-game wont actually be able to be heard, if you want to revert it without restarting then just place another Energy Vessel Explosive and let it explode, The audio should come back after that.

So my idea is that zooi made the sound cut out for a dramatic feeling when the explosion happens, Or maybe the audio file is missing, So when the audio cuts out, It doesnt just affect the explosion sound it affect the whole sound thing, So the sound gets muted for a second then it comes back when the game registers that the real explosion should happen.
