This is an addon now released for Amnesia: The Dark Descent. It allows you to play as your choice of one of the 6 main characters of My Little Pony in both the campaign as well as custom stories.
I had Version 2.0 of this mod for a good while. I have to say, this isn't that bad. I actually give credit where is due, it must of taken the person who made this a long time to edit a good bit of amnesia configs & other things just to make this mod. I'll give this mod a 10/10 just because of how much this person worked on it. Unlike some other CS or mods out there in the community that had little to no effort at all.
