Amnesia Total Conversion Install Instructions:
ON WINDOWS
1. Unzip and copy the whole a_mod_pactum_tenebris folder into the Amnesia directory:

C:\Program Files\Steam\steamapps\common\amnesia the dark descent
- for retail
C:\Program Files\Amnesia - The Dark Descent\redist
2. Enter the folder a_mod_pactum_tenebris and launch LaunchPactumTenebris.bat
3. Enjoy!
ON LINUX and MAC
Follow this awesome tutorial but keep this in mind:
From time to time the guide makes a reference to the file wn_config/main_init.cfg
For Pactum Tenebris, change that to a_mod_pactum_tenebris/config/main_init.cfg
For every question, feel free to send me a private message or write a comment in the mod page.
Have fun!
