Hehe, I got past that level in the end guys. Cheers for the tips.
Has anyone seen that level where there's a technician stuck inside that room yelling at you to let him out? There's two buttons, one for opening the door and one for activating the machinery.
Obviously being the kind fellow that I am I was going to press the 'open doors' button to let him out, but unfortunately my finger 'slipped' and hit the other button. Kinda funny what happened to him (in a grim, saddistic way).
Muahahahaha, why is it so much fun to be evil.
