This is simply a normal map for you to enjoy and learn, the author shared that he spent a lot of time for it. There are many interesting things of this map, a castle with a subway system inside. At first look it you will feel something mystical and a little horror, but not to worry about anything, because it’s just an empty model. If anyone interested can download it and design your own style, I think this map might create a lot of interesting challenges. Have fun !
