Famed director Eli Roth has released a new animated trailer called The Witches. The Witches is an original story set in the world of Dark Souls 3 where a lonely, weary knight finds himself confronted by three witches. Roth's direction certainly captures the horror feel of Dark Souls, although the specifics of the animation don't really seem directly related to the game.
There is also a behind the scenes video as well that can be found at: https://youtu.be/2MdIht2tRjk
