Theme wad

While exploring all the different wads, I knew that I wanted my theme to be surrounding both mechanical (industrial) and medieval themes. After searching, I found a wad that I particularly liked that surrounded snow and ice, as when I played through quake I did not encounter many snow filled areas. As such I think I would like for my theme to be mainly a ice and industrial one. The idea I have in my head narrative wise is the player was undergoing experimentation from scientists, using demonic tech / energy. Then an experiment goes wrong, facility is damaged and there is an influx of demons funneling into the facility. The players goal is to traverse the ice filled facility and escape.

I would like to start the player in an exploded room where ice is slowly creeping its way in, then take them through winding hallways showcasing some demon tech themed areas. Then I would like to switch between more mountainous and industrial areas till the final boss which would be outside in the snow.
