An Insane Cancer IS from Silent Hill. The 3rd one in fact. It's just a little chubbier with a more darker, bloodier look. The head is a little more indistinguishable from the body. And if you don't just run past it, and take the time to kill it like I did, you can wait for a moment and watch it deflate like a balloon with a pin hole in it. Turns from gelatinous blob to puddle of rotted flesh in seconds! But excellent job!
