Mills I never envisioned you as a video game player but know they be addictive. I can't get enough spare time to play Halo 3 on my Xbox 360 even though it can be highly annyoing having to listen to 12 year olds screaming, cussing........ but that's why I usually play with a more muture group of friends I have met online.
Is the game your talking about called "The Suffering" ? If it is here's a link to a walkthrough that should help if you get stuck.
If the link dosen't work just Google "The Suffering walkthrough" and that should pull up what you need.
