So as you may know, there comes a part where you have to kill HER in front of her grave. One problem I had (as well as Uberbob) was starting the part with ammo, like the world record holder at the time did. It's a lot simpler a solution than I thought.

So, go into your IMSCARED game folder. The Steam one, not the one on your desktop or in %appdata%. Then, find the file named "revolver20.ini." Set the bullets to 6 in that file, and set it to read only. There, done, easy.
