In the original rules of the futuristic wargame KILL ZONES, for playing the miniature ex Grenadier and now Copplestone, I have not found the Zombies, then I do not know how they would have made by Nick Lund (author of Kill Zone).
By chance, does someone known if Zombies are been included in a later version, which I think now it is named "COMBAT ZONES". Does someone knows it, does someone play it?
