This story is about a virus that was created by a fungus that came from Germany called 2-HD Trident, which soon managed to evolve into new variants over time. With this virus, Jenna Makkalver founded a front company called B.C.S Corporations, which studied this fungus until it became something terrible and transformed almost all of humanity into zombies or mutant creatures.
The Makkalvers are the real culprits.
(Remember that it was also inspired by Resident Evil and religious beliefs and has a high level of horror, gore and terror, so this work is classified for ages 16 and older due to inappropriate language and the high amount of gore and blood. You have been warned...)
