Defeated Scarlet.

After the cutscene (a non-interactive cinematic the game plays automatically) in Dr. Fitch's Office, you will receive the Founders Key.

Exit Dr. Fitch's Office and head east on Main Street to the Town Hall.

Save your game at the save point in the northeast room if desired. Note that Smogs (monsters that constantly respawn (be brought back to life at a checkpoint after death)) in this building are a waste of ammo.

Enter the middle room of the Town Hall, which contains a large podium and paintings of founding fathers.

Walk behind the podium on the east end of the Founders Room and use the Founders Key when prompted.

A section of the floor will rise, revealing a stairway.

Go down the stairs and pick up the First Aid Kit under the archway directly ahead.

Proceed down either the left or right tunnel; they both lead to the same area.

Turn off your flashlight and enter the narrow tunnel.

Be prepared to sneak up on and defeat three Nurses in the large room ahead using your chosen melee weapon.

In the basement area, locate the four Ancient Books. Two are near the tunnel you entered from, and two are on the opposite wall.

Examine the cross on the right side of the room to trigger a cutscene.

After the cutscene, you will receive the Ceremonial Dagger, which replaces the Combat Knife.

Locate a door with a slot, blending into the wall between the two books across from the entrance tunnel.

Approach the door and an "Unlock" command will appear.

Equip the Ceremonial Dagger and use it to unlock the door.

Enter the area beyond the door, turn right, and follow the tunnel.

Turn right again and follow the next tunnel, which will lead to a four-way split.

The right and straight paths are dead ends. Go right.

Continue straight ahead, then take the second left.

Follow the tunnel to its end, where you will enter a room with a desk and typewriter on the left.

Climb the ladder on the side wall to surface in one of the east mausoleums in the Founders Garden of the Rose Heights Cemetery.

Turn left from the ladder and take the Child's Drawing (13/18) from the left wall.

Equip the Ceremonial Dagger and use it to unlock the mausoleum door.

Use the Ceremonial Dagger to unlock the mausoleum directly across from the current one.

Step inside, open the medical case on the right coffin, and take the Serum (5/8).

To find a photo, backtrack to the east street outside Rose Heights Cemetery.

Exit the Founders Garden through the north gate, enter the West Garden, head north to the Parking Lot, and exit through the east gate.

Move west down Main Street and go to the Missing Persons billboard.

Pick up the Photo (9/11) on the ground in front of the right side of the billboard.

To find more items, backtrack to the far south portion of River View Road.

Move past the Smogs and across the bridge to the Junkyard.

Pick up Shotgun Ammunition and a Health Drink near the fence. The Junkyard gate is locked.

Return to the backyard of the Shepherd House via the Founders Garden.

Move up the stairs on the south side of the Founders Garden, head west, and drop into the pit.

Duck under the opening on the north wall, as the previous opening is blocked.

Two Smogs will attack; defeat them with your handgun or shotgun.

Run to the end and collect the First Aid Kit and Shotgun Ammunition on the north side.

Backtrack and find the opening in the west wall, then duck under it.

Climb out of the pit and move through the gate.

Defeat the Smog to the right with your handgun.

Squeeze through the narrow hole in the wall between the tombs on the west wall to enter the Family Crypts Mid Area.

Exit the crypt and move through the iron gate to the west.
