Part 18

Against Sentinel, use Electric Bolts to stun it and unload your weapons. You can also set up Electric Bolts as traps. Aim for its head when close. Freezing it is also a good strategy.

Items scattered around the arena include an [ELECTRIC BOLT] near a middle pillar, [SHOTGUN SHELLS] near the exit gate, [HANDGUN BULLETS] near the entrance gate, and [CRATES]. It is recommended to save these for the second phase when retrieving Joseph's glasses.

After the first phase, a cutscene (a non-interactive cinematic the game plays automatically) plays, and you must retrieve Joseph's glasses. Sprint back to them, grabbing any previously skipped items. Joseph will help distract Sentinel.

Note: You cannot kill Sentinel during the first phase, but you can during the second phase. This is not recommended unless on New Game + or higher. The reward for defeating Sentinel is [7000 GREEN GEL].

After the Sentinel encounter, head up the large stairs and inspect the left part of the area for [1000 GREEN GEL]. Approach the door to finish the chapter.

Inspect the left side of the church to find [5 MATCHES] on a bench.

Find [2 SHOTGUN SHELLS] on a bench towards the front of the church.

Check near the pulpit for [300 GREEN GEL] and [MAP FRAGMENT 13].

Talk to Joseph to trigger a cutscene.

Move through the hall, smashing a vase, and enter a large room.

In the corner to your right are large grey vases (like crates) containing random items.

Find [500 GREEN GEL] at the far other side of the room, but beware of a nearby trap.

After the trap, find [5 HANDGUN BULLETS].

Collect [2 PARTS] on the altar.

Move to the large painting and head upstairs.

Take out the three enemies upstairs, including a fat one.

Explore the room for [1000 GREEN GEL] and [2 SNIPER RIFLE ROUNDS]. There are also vases with random items.

Go around the corner of the hall and grab [7 HANDGUN BULLETS] and destroy some vases.

Inspect the [OLD LITHOGRAPH] to continue.

The room behind the lithograph contains [2 PARTS], [800 GREEN GEL], and the [CATACOMB NOTE].

Examine the wooden box on the table for an [ORDINARY KEY].

Head downstairs, break vases on both sides, smash the lock, and place the lithograph in the middle slot to open two gates.

Go to the red door in the upper right corner and inspect the floor for [300 GREEN GEL].

The room contains [LILY'S BIRTH ANNOUNCEMENT].

Enter the save hub to find the [CATACOMBS FOUND] newspaper and the [MISSING PERSON POSTER - CHRIS].

Go down the initial left path.

Turn the valve to cut off the gas leak and head through the doors.

In the next hall, lure out a two-headed creature and shoot the one hanging from the ceiling to trigger a spike trap.

Kill the creature in the cell.

Search the cells for [4 MATCHES], [5 HANDGUN AMMO], and an [AXE].

Ignore the gate on the far right for now.

Head upstairs, sneak past a bomb, and pull the lever on your right to eliminate creatures below.

Go back to the gate you passed and collect [2 PARTS], [500 GREEN GEL], [3 SNIPER RIFLE ROUNDS], [4 HANDGUN AMMO], and a [SYRINGE].

Return to the hall and enter the room with the torture chair.

Stay crouched due to a bomb at the back and collect a [GRENADE] from behind it.

Continue down the hall.

Head down the ladder. The Keeper will appear.

Quickly move to the first valve and turn it.

Go to the second valve. A creature appears; kill it first, then turn the second valve.

Grab the [3 HANDGUN AMMO] near the ladder at the end of the walkway.
