Sewer Tunnels, Expert (Patreon)

Hi folks! This map is the Sewer Tunnels (30x25), an intersection of thick pipes beneath the city streets. I don't doubt all kinds of grimy underworld denizens are up to their dark deeds here, or perhaps in some forgotten corner of these tunnels a dark mound of slime lurches down a corridor toward a group of unsuspecting adventurers. Those are the two ways I've used this environment in my personal campaign, but I would assume there are probably a few other thing that can happen in a nasty place like this. 

Your alternate version this time are Pristine and Irradiated, and you can probably tell what's up with both of them at a glance. The pristine one is much more cheerful and bright, the water is a vibrant blue and there's barely any grime to be found anywhere. The Irradiated one is pretty cool I think, providing a little more danger to the map while setting you up for mutated creatures that lurk in the ooze. 

Hope you like it!
