Deterioration is a full conversion for Amnesia: The Dark Descent, featuring an entirely new focus on atmosphere and horror. It focuses less on startling the player and more on immersing the player in a deep, subtle story with psychologically horrifying themes. All item glow has been disabled, so try everything, repeat, EVERYTHING. All items include a description of their use upon interaction, so if you're stuck, try messing around with everything, and think hard about your ultimate goal. This story was inspired by Myst, so the puzzles will feature similar attributes and you will need to use your head often. Play in a dark room with headphones if possible.

On Installation


Okay, so I've noticed there are several people making note that they need a serial number, or that the mod is too buggy for them to run. I would like to point out that I have tested absolutely every part of this mod time and time again, and for a solid two weeks after initial release, I released updated versions in order to squash out every unplayable bug that people made note of. However, since releasing it here on Moddb, I've noticed a stream of 'serial code required' problems. I'm here to address this.

Now, to address the issue of Serial Keys. This is either happening because you obtained Amnesia through illegal means (just pay the damn price, Frictional Games deserves the money, guys!) or you installed the mod wrong. There is no reason why my modification should require the use of another serial number. If this problem persists after installing it correctly, try looking in "My Documents/Amnesia/Main" for the installkey, then copy it over to the "My Documents/Amnesia/Deterioration" folder.

As for people making note that the installation broke their Amnesia game, you installed it wrong. There are two files in the .zip file, a folder called Deterioration and a Deterioration.bat file. These two files are to be dragged directly into the main Amnesia folder, so that the .bat file is in the same area as Amnesia.exe, and the folder is right alongside the other main Amnesia folders, such as static_objects, entities, sounds, etc. It should not be in the custom_stories folder, and you should NOT go into the Deterioration folder and take the contents out and merge them with the initial Amnesia folders.

I hope that clears up the issues. Enjoy!

I found a very strange glitches, SPOILER ALERT: 1)after opening your father's desk, i returned to the bathroom and fell into madness...well then i hit continue from the menu and i started the game from the father's desk... and the camera was locked on the desk, i moved the mouse and the player but it continue to focus on the desk and the inscription ''The XXXX is gone'' appeard every time the camera points to where the desk must be.
2) I can see what's in the desk without open it, just forcing the view in the little open...after that i lose the option to retrieve what is in the player's room because the room get corrupted and the items nowhere to be found.
Well so far, this TC is amazing...but i had to re-start it a few times again because of this glitches.

I really want to play it, but whenever I click on the .bat file it shows me this message: "Could not load main init file: Deterioration/config/main_init.cfg "
And piece of advice would do! Thanks!

I've got a problem with this mod. Let's say you didn't go back to one of the very first rooms to get the drill crank after obtaining the sharp drill bit. Let's say you just proceeded on to the other areas without getting that drill crank. You will then be stuck because the slime blocking all the doors later on. I couldn't go back and get that drill crank after the doors became blocked so I couldn't proceed. That seems like a major design flaw to me.

You can't progress to the areas with the slime without the drill.
