It`s done, "The Endstory" is a fully isolated full conversation mod for Amnesia: The Dark Decent. Mainly, this means a very easy installation for you: just copy the "The_Endstory" folder inside your Amnesia root folder. That´s all.
For me is this easier, because I`ve got everything together, and I don´t have to change any original Amnesia files.
The demo will be ready to play in 2-3 weeks I think.
Thank´s for reading!
