His quest has been completed. But what if there was another he needed to fulfill? The Doom Slayer instead must embark as Mankind's savior in this world. No longer does he face the endless legions of Hell. He now faces an endless legion of man-eating giants called Titans. But even with these monsters. Mankind is still its own worst enemy. But William is a good Shepherd.

Just as all hope was thought to be lost, a mysterious figure appeared out of the shadows. Seemingly full of anger and bloodlust. in an instant the mysterious figure killed a titan with his bare hands. The other titans stood still, not being able to understand how such a small being could kill a titan. But they had underestimated him for he is THE DOOM SLAYER.

"So you walk eternally through the shadows, standing against evil where all others falter. May your thirst for retribution never quench, may the blood on your sword never dry, and may we never need you again."
