I am in the Nut House in the game and I've killed all the enemys that I can find. What I need is the key that is in the Morgue, how do I get it? I see a power sign floating above it, does that mean that I must shut off the power that is in the beginning of the game? How do I get through the gate? I can't seem to find a way to get into the room with the ladder behind the gate. Please help.
