stuck in black plague - after machine room

[DiNeRo]

cant remember that part too clearly but if im correct you need to use the saw to cut the guys hand off

yeah I think you're right - which guy though? Tried it on the dead body in the hallway...is there anyone else?
thanks

well theres this guy laying in a corner room with some electric device, you saw his hand off and then the big worm thing crashes in... wont spoil how to solve that though ;o
