I had a Frostpunk itch, and this dlc really hit the spot for me. It was just as addictive as the main game for me. The way you had to manage your work places' safety levels and manage your workers' motivation/strikes instead of having to deal with the cold (well at least for most of the DLC) was a really nice change that kept things fresh. It still was really challenging, and I kinda want to say that I found it even harder than the main campaign, well at least towards the end. I had lots of fun being the worst boss ever.
