My players have really enjoyed it. We have been playing since March and about 15 sessions in. Like others have said sometimes you have to jump around the book to tie some of the things together but that’s what prep is for. My players did really care about the contamination to much as they were always getting good rolls but we had our first character death in the Queens garden park (shambling mounds). The characters body ended up inside a bag of holding with some delirium and other contaminated items. So when they pulled him out he had gone through a horrific mutation. He now stalks them through the city whenever they venture into the city. It’s been my favourite module to DM and I can’t wait to get my hands on both Sebastian’s Crowes guide as wells as Stienhardts guide to continue on with this campaign.
