Yeh ignore the guy getting electrocuted. Go back near the balcony and look at the burning mound of headcrabs and zombies on hooks and find the gas cylinder. Turn it off and youll see theres a door going into the main building. Go in there and look about. :thumbs:
Go to the area below the balcony with all the roasting bodies and turn off the fire with the switch near that white tub of gas. Once the fire is out, go inside and upstairs to turn off the electricity, then you can go over that fence.
Argh, I'm past that, but this level is confusing as hell. To get past that, there is a door somewhere that leads into the window where the electricity is coming from. Anyone know where the hell the church is?
