Half-Life 2 Walkthrough - Chapter 6: We Don't Go to Ravenholm - The Church and the Cemetery
Time to find your salvation with father Grigori at the church. You just have to go a bit further before you're out of town, but it will be one heck of a fight. If you need any help getting to the church or through the cemetery, then just read this.
Seeking the Church
Go into the room and up the stairs. Kill the group of zombies and just keep going. Go down the first set of stairs and kill the zombies at the bottom. Don't go down to the room on the left. It leads you back to the beginning of the first street. Just go to the right and climb the ladder. Kill the headcrabs and step out of the door.
You're almost at the church. Go across the wooden planks to the roof. Watch out for the two fast zombies moving around the area. Just keep going forward along the rooftops and watch for the square with the poison headcrab carrier. Drop down to the square and run up the winding stairs to the door. If you move fast, you'll avoid the fast zombie who drops in and all of the poison headcrabs. Open the green door and close it behind you. Grab more health and ammo. Then climb up the set of ladders and pop up through the hatch unto the roof.
A Slow Mine Cart
Grigori will call out to you again and then proceed over to the cart station to send over your new transportation. You just need to hold on for now. Pick up the ammo and notice the two pipes on the building. The next attack isn't predictable. You just have to be ready. Watch and listen for the pipes to start moving. When one starts moving, lean over the side and shoot the fast zombie with your shotgun or your magnum. Grigori will call out again once the cart is ready. Just jump in and pull the handbrake to find sanctuary at the church.
Gather up some more ammo off the table by Grigori, and then get ready for more zombie killing.
This is actually pretty easy. Follow Grigori over the board to enter the Cemetery. He'll stop and handle the five fast zombies who attack. Help out with your shotgun and then go past the fence. Father Grigori is probably able to die, but he regenerates health at such a high rate, that it is very unlikely. If you want, you can probably just run around and let him kill all the zombies.
He'll stop at the entrance to the actual cemetery to kill the group of zombies approaching. Pull out any gun or pick up the saw on the ground to help. Then follow him around the corner to the second row. He'll take up a position on that marble slab. Stay close and fight the next group of zombies. There are five or six that should come from in front and another 3 or 4 that come from behind you. Once they're dead, he'll advance again to that raised stone position at the corner. Just wait and kill the zombies coming from both directions. The only real danger is getting caught up in an explosion. Use your gravity gun to clear out the explosive barrels close to the platform.
Follow Grigori to the next area by the mausoleum. He'll stand on the weighted plate to raise the gate. Crouch under and watch Grigori make a really epic stand against the zombies before he retreats into the mausoleum.
Turn around and enter the house behind you.
