Refinery

Follow this guide to progress through the Refinery in Amnesia: The Dark Descent, find items like oil and tinderboxes, and solve the trapdoor puzzle.

At least we're at the Refinery! Move forward and you'll have another flashback of Daniel asking Alexander why it's so dark in the Refinery.

Continue moving and you'll eventually hear another weird sound. Just move along and you'll reach an open room with giant barrels. As you enter the room, you'll see a monster move in the next room. When it's gone, you can continue moving forward as well.

The next room has a slightly open door to the left, with another door at the front and to the right. Giant barrels are also here. Enter the slightly open door to the left.

The room is just simple. The only thing of interest here is the shelf on the left which has a bottle of oil. After getting the bottle of oil, turn around and proceed through the next door.

It's another small room. There's Laudanum on the shelf, and a note on the table. As you approach, the door to the next room gets blown open by something. Nothing to worry about. Grab the Laudanum and read the note.

The note is about Daniel's return from Africa. He was forced to go back home by Professor Herbert. He also found the broken orb, but somehow couldn't put them back together.

After reading it, proceed to the next room. Don't bother with the door to the left yet since we're not done with the area. Just move forward and go through the slightly open door in front of you. The screen will turn red and another angry growl is heard, nothing to fear.

When you're inside the new room, check the shelf on the right and grab the tinderbox. Proceed to the next room. As you make it halfway through the room, you'll hear an angry growl and the sound of something breaking through a door. Nothing to worry about.

There is a table with a note on one side of the room, and there is a shelf on the other side with a tinderbox at the bottom. Grab the tinderbox and then read the note on the table.

We find out the Daniel's beginning to suspect something's strange about the pieces of the orbs that he has. He asks a geologist about how rocks change, and somehow felt at ease. Still, he finds the orb pieces bizarre.

After reading the note, go back to the previous room, and then to the other. Go through the door and you're back to the long room where your vision turned red. Look to the right and you'll find a bunch of boxes. Move the boxes away to reveal a hole in the wall that you can crawl through.

Move forward and you'll find an oil barrel to refill your lantern with. Turn left and continue and you'll find a trapdoor on the floor with a rope attached to it. Don't worry about it for now.

To the left of the trapdoor is a shelf with a tinderbox. Grab it. The left side of a room also has a chest under a torch. Open the chest and grab two tinderboxes.

Now we're ready to open the trapdoor. Unfortunately, something is jammed to the pulley so even if you turn the crank, it won't work. We have to get rid of that stick jammed to the pulley.

Trapdoor Solution

Solution 1: Grab a box and throw it at the stick that got jammed just above and front of the trapdoor. The stick will break and you'll be able to turn the crank to open the trapdoor.

Solution 2: Get a few boxes or a barrel and make your own stairs to reach the stick. Grab the stick and move the mouse around to break it. Turn the crank and the trapdoor will open up!

Now that the trapdoor is open, it's time to get down there! Crouch and fall through the trapdoor. Just keep going. You'll hear another roar but it's nothing to be scared of. Go through the door to reach the Cellar Archives.
