Remember playing Syphon Filter 1 with a taser on PS1?
I would hold the trigger down until the battery ran out. I didn't allow their burning clothes and exploded throat stop me from continuing to hold it down. After the hours of torture, I'd shoot every part of the corpse until it was red everywhere. It's probably a good thing that I will never do this in real life. It's pretty sickening. Here's a video.
