This is really Wicked for the Underhive and since it was published 5 years after Wicked, it really could be an influence. I really didn't like Wicked, couldn't even get though it, as I really don't care for the world of Oz and really just wanted my wicked witch to be wicked & not troubled, but I did like Survival Instinct. I do love all things Necromunda, but didn't really care where Mad Donna came from. Still don't really and can't understand GW's infatuation with people fleeing the spire into the Underhive, but I did like the story here. I did find it weird that there was a ekranoplan on the sump (Google it, it's weird vehicle). The author must have seen a picture of it and just decided that a contraption that weird needed to be in the story. Really good description of The Sump at the end that was practically worth the price of admission alone. Nice to see some of our old standbys of Escher, Delaque, the Goliath Dog Soldiers gang, Pit Slaves and Guiders.
