This map was made for the 193th Quake Speedmap event, the theme was "Quakeguy goes to White Castle".
It can be downloaded from here : https://www.quaddicted.com/reviews/sm193_pack.html
Made in around a week, using some previously created prefabs from an unfinished map.
Most of the textures are from Chicoverde and heavily modified by myself. The skybox was mashed together from various sources, and inspired by art from the amazing Yuri Hill (https://www.artstation.com/hill/).
