When I was first rolling this idea around my head I didn't take into consideration that Warrior Heroes: Legends is no longer in the Two Hour Wargames' store, so anyone wanting to try to this will have a rough time of it, unless they already own a copy of Warrior Heroes: Legends, along with All Things Zombie: Final Fade Out.
All is not lost, though. There are two alternative rule books that can be easily used to accomplish the same result:
ALL THINGS ZOMBIE: EVOLUTION
TALOMIR TALES: DISTANT SHORES
These are the rule books I will use to create my rules variant for ALL THINGS ZOMBIE: MEDI-EVIL, because they are both readily available from Two Hour Wargames.
Now, I need to familiarize myself with both rule books so that I can merge them for ALL THINGS ZOMBIE: MEDI-EVIL. As soon as I have done that, I will get a game going for an AAR to be posted here.
