That’s pretty cool. Like you, I’m sure something along those lines was tried during the cold war. You’ll probably find there are a few lunatic cadavers in cold storage somewhere in America just waiting for the plug to be pulled & to thaw out before the killing spree begins. I’m not so sure about the jellyfish/superhuman thing…. although it certainly conjures up an image :) I suspect the closest thing to Zombies are those Haitian, chemically lobotomised victims of Voodoo or Santeria that you sometimes hear about.
