You are an unnamed mercenary and soldier who received a letter from your brother (also unnamed, though online sources identifies him as "B"), an archeology student currently in Eastern Europe, asking for you to attend an unveiling ceremonry as he excavates an ancient archeological site. But after a lengthy train ride into Europe, you realize the town you arrive in is suspiciously devoid of all life.
And in the equally-deserted hotel your brother rented for you, you discover a pistol in your bedroom. And suddenly there are zombies; which you instantly dispatch given your expertise as a soldier, but on the trail for clues you entered the local church, and meets an angelic figure who calls herself the Angel of Faith, who informs you that your brother - as well as the town's entire populace - has been dragged into the Netherworld after disturbing the peace between angels and demons.
Determined to retrieve your brother, you volunteer on a mission into the realm of the supernatural, with the Angel of Faith as your guide as she bestows you a holy sword and imbues the soul of her demonic servant into you...
