Hi Scott. Yes the Roll20 SKT has Ironslag in 2 map-pages (Upper and Lower). If you get Roll20 paid subscription it also has Dynamic Lighting Walls set up (so that PC Tokens/minis can only see the hallway/room that they are in). Without a subscription on free, you can still hide parts of the map using Hide/Reveal masking tool, and manually carve out chunks/rooms to reveal as they go along. So, either way, it is set up great for Ironslag and really the whole module like-so. Are you planning to run it in D&D 2014 or D&D 2024? There certainly are some additional steps (that may be headaches) if you want 2024 rules bolted-on.
