Go to the following file location:

C: > program files (x86) > steam > steamapps > common > Amnesia The Dark Descent > PrisonerOfFateDemo > config

There you will see a file called 'game.cfg'

Right click on it and click 'Open with' and then click on Word or Notepad.

In this file, scroll down to the section 'Player body' and change "CrouchSize" to "0.01 0.01 0.01" and the 'GravityForce' to "0 0 0"

There. You can now get out of the map by pressing 'ctrl' next to a wall. You'll be able to walk right through the wall when you crouch. Sometimes when you press jump (space) you fly up forever since you disabled gravity, so avoid pressing space.

In case you just want to quickly see what is hidden, here are some screenshots I took after boundary breaking.

1) outside the first place you spawn (inside the incinerator). Behind the wall on the right is the actual incinerator, so when you leave the inside of the incinerator you are just teleported to the room with the actual incinerator.


2 and 3) When you leave the incinerator you will see a shadowy figure walk past and then disappear.
This is the shadowy figure up close. It looks like he has only one arm but that's just because one of his arms is very close to his body.
One of these pictures shows an angle where you can clearly see both arms.



4 and 5) The figure that closes a door near that big fan. You can throw objects at him and they will bounce off, so it's a solid object.





6) You can see the room where the first cutscene takes place (the woman talking to Red just before he wakes up)



7) All of the dogs in the cages are fully rendered and identical to the ones in Overture.


8) You can get past the poison,
allowing you to walk to the door to Lake Utaqaq in picture 9.


9) The door to Lake Utaqaq past the poison.
You can click on the door and a sound will play but you cannot open it and visit the lake sadly.

10) Another angle of the acid beneath the wooden planks you use the crowbar and glass container on.

11) The dog that patrols the area near a barrier. It doesn't interact with the player at all, as it is just repeating its movements over and over (back and forth)

12) A closeup of the image on the projector that changes to the picture of the rockworm.

13) Behind the metal gate you can see a light going on and off. You can go through the metal gate and see that there is actually an infected there, patrolling the area with a flashlight. Usually you wouldn't be able to see this infected at any point, only its flashlight.


14) The valve next to the metal gate has a keypad on the back of it. You can't interact with it and I guess it's just a reused asset.

15 and 16) The locked door you walk past. Image 15 shows the door so you know what one I'm talking about, and image 16 shows what's inside the door. Nothing important really.



17) You can go into the room with the conveyor belt.There are some valves there that you can touch but not turn.

18 and 19) You probably want to know what's behind the door where you can see the shadows of someone's legs. Image 18 is the door I'm talking about, and image 19 shows that there actually is a shadowy figure behind the door. The same model used in the first few pictures.



20) The spider waiting in the vent ready to do the jumpscare.


21) Behind this gate is a purple artifact, different from the orange and blue ones in previous games.


22) Closeup of the purple artifact. You can't interact with it.


23) When you click on the gate in image 21, a cutscene plays where two people run across the screen behind the gate and behind the purple artifact. Walking past the purple artifact using boundary break before the cutscene allows you to see the 2 people in a t-pose position, waiting for you to click the gate to trigger the cutscene.


24) And once you click, they run across and off the screen, out of bounds, and stop after a short time, but their running animation continues forever.

25) The ladder you climb up to get to the vent has other ladders sticking out horizontally off screen.
Don't know why.

26) When you learn the code to the door and begin walking back,
a hand falls from the hole in the roof.
Then you can see lots of blood animation.
This is another angle of the blood.
Before the cutscene, the hand is nowhere to be seen.


27) When you run to the door to enter the code, there is banging on 2 doors. However, there is nothing behind either door, proven in image 27.
