The problem wasn't those mindless zombies,but the unnatural physics that
had brought them about,as well as other unnatural things.
After the United States of America had broken apart and fallen into the Second
American Civil War in on December 8th 1941 people had quickly chosen sides
a) Declare war on Imperial Japan ( a given for all sides) but stay out
of the European conflict
b) or declare war on Germany as well as Imperial Japan
Which meant that cutting edge scientists such as Einstein and Oppenheimer
had soon parted company as their respective separated nations employed them for more useful pursuits
then splitting the atom.
Instead these scientists took to splitting time itself and by the time the first
Chrono Reactor went live in 1944 there were the first reports from the countryside of the dead temporarily
coming back to live at the same time as
Chrono 01 split chronotons.
Unfortuneately the folks higher up dismissed those reports of the dead coming back to
life as old wives tales and so in 1945 both sides dropped the first
C Bomb's on each anothers capitals.
Which was when the zombie horror really began to pick up speed.
It was now 1946 and no one left in the Divided States of America had a clue what was
going on in Europe or over in the Pacific.
What Carly and Susan had known was that their mother Elvira Pentergaust had been involved
in ways to undo the effects of those C bombs that had unleashed
the zombie plague a year earlier
Solve the C radiation problem and you'd put the walking undead back where they belonged.
