The End is Nigh
They say angels once rebelled against God and were cast out of Heaven. Hunters don't know if Scripture gets it right, but they do know one thing: Darkness has fallen and its Hell on Earth. Things that can be called no less than demons walk among us, tempting the righteous, corrupting the innocent and orchestrating the end of the world. Can they be stopped before the Devil gets his due?
Hunter: The Infernal explores the blasphemous realm of demons as hunters desperately seek out devils' strengths, fears and weaknesses. But the tempters have discovered hunters, too, and are willing to strike a bargain. Can hunters possibly drive the infernal host back into the Pit? If they can't, there will be Hell to pay.
