You want them dirty, muddy, tortuous ? Then you're at the right place.
Meet my sewer system : tunnels, rooms and tons of assets, you'll be able to create complete sewing systems that will hinder your players, make them run knee deep in dark foul water, crawl and fight in confined spaces. Make your player fear what is in the corners, make them learn that sewers mean dungeon crawling not having a walk in an avenue.
