The creator of Scavenge, Skirmish, Survive got in touch with me through the Post Apocalyptic Wargames Forum after reading this review. I'm honoured!
I have a couple of clarifications to issue.
Firstly, I misread the rules regarding blizzards. In order to be affected a model has to be outside and without a supply bag. As almost everyone has a supply bag the rule will effect very few models.
Secondly, the extra expense of boy characters was, as I suspected, a typo, or rather, a holdover from a previous version of the rules, so SCUM lose this one.
