Completed the "Cinma Vrit" side quest.

Location: Theater
Prerequisite: Should grab the light bulb from the hardware store first. Read full description below.
Best time to complete: Should be the first thing you do when in Chastain Heights area after the cut-scene when you escape from the Centennial Building.

This will be your first side quest in the new area of Silent Hill called Chastain Heights. Before you head inside the theater, head through the alley South of the theater. Go along the road that curves up and left. Follow it until the dead end. The door with the light above it is a hardware store. Inside is a shotgun and the bulb you need for the quest.

Now that you are prepared, head inside the theater.

Film Reel 1 - The House on the Lake:
As soon as you enter the theater, go behind the concession stand on your left and there is a back room with this reel.

Film Reel 2 - The Silent Children:
Continue on until you get to the movie screen area. Facing the chairs, look at the 2nd to last row on the left side.

Film Reel 3 - The Secret of the Attic:
Now to go the room that's on the right side of the area. Go up the stairs, past the projector, and in the back room is the last reel.

Spliced Reel:
You can skip part of the quest by just entering in the code 9241 on keypad by the door (near the projector). Splice the films together to make one.

Now what you must do is use the light bulb you got from the hardware store to fix the projector. Now play the film, and run down to the screen and enter it. Go along the sidewalk and into the house. Pass the stairs and open the door to your left. In the room is a crank on the window. Exit and go through the back door in that hall. Continue through the next, and in that room there is a jack-in-the-box. Use the crank to get a key. Now go to the corner of the room to find a ladder. Go up and locate the chest. Open it and grab the golden gun. Now enemies will attack and it's extremely hard to navigate this area based on the camera angles and losing the ability to effectively aim. Run out of the house and back the way you came to exit.
