It has been a perfectly fine day until Jerom gets a call from the government about the discovery of a tunnel system. We were absent-minded and without knowing, by sending researchers into the tunnel system, we were opening Pandora's Box. Black smoke rushes outside through the interdimensional portal, infecting whatever it sees, mutating them into horrifying creatures. The world is about to end. And surviving will be a difficult thing. Now, all we can do is pray to God. But God is hiding in his little hideout, peeking at the losing battle the humans are fighting against the demon horde. Get ready for the beginning of the ultimate battle of the century. Even if we survive, we will be in a new world where there will be no kindness or kind people. The survival of Earth depends on our survival.
