VIAL-16

VIAL-16 is a Japanese project developed in 1946. It could rejuvenate the dead cells of a body and bring it to life. This could create a large Zombie apocalypse. But if the subject was already too irradiated, it would instead evolve the cells.

It was completed in February 1951. The Japanese deployed it all over the World in April 1951, the day they nuked the World.

In May 1951, the Japanese disposed of all VIAL-16 tubes. However, in 1953, one leaked in the city of Nagasaki, which spread all over Japan, destroying the country as radiation flew over. Some traces of the escaped virus went onto refugee ships heading to other areas, worsening that areas VIAL-16 exposure.
