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.
This mod is AMAZING! I flipped out when I saw this because I was so excited to try it! The mod didn't fail me. Its an amazing mod everyone should try. 9/10 because I encountered a few puzzles where I couldn't find a key on a high shelf because I was so small. My friend, (who doesn't have the mod) found the key right away after I looked for a few minutes. Otherwise great mod. All the sounds were exactly as I imagined the creator would put in. I especially liked it when Rainbow yelled, "HELP ME!" XD. The height of the character is great, just like I thought a pony would be like. I recommend this mod to anyone, fan of the show or not.
It's about darn time!! I have been waiting for a pony mod for Amnesia for a long time, and at long last, it's here! This mod has made the Amnesia experience a lot better playing as a pony. Voices are great, footsteps (or in this case, hoofsteps) sound like I am one of the Mane 6, and the fact that I am now smaller in size makes me feel even more helpless than I was before. I will leave the rating 9/10 for any future updates but so far, I have not found any flaws.
