This entire first episode was written to simply establish the good from the bad characters and incorporate the Undead as quickly as possible, and as such I think it works quite well; albeit being a bit obvious that the grandmother was up to no good.
I've written drawn many zombie stories and their appearance has hardly changed at all since I started. For this adventure I simply mixed my standard cadaver heads onto the bodies of some German soldiers I'd created earlier and dirtied their uniforms up.
Miss Priscilla must fight for her life in a house quickly filling with the hungry Undead. But beneath the waves a second army of walking corpses is stirring, and Ermin Meonstoke must use all his powers of persuasion to save the passengers on board the cruise liner Eclipse.
