I know why it doesn't work.
This is a mod of madness interactive, the file would have worked on the computer it was made on, but the sounds for it are stored in a separate file which could not be uploaded. So the file constantly tries to load the sounds but can't. This makes it not work. I give it an 8 because I know the person who made this and he put a lot of effort into it. I may be able to help him fix the problem and he can upload it again in a working state.
