Eternal darkness has gripped the city of Serling. What's worse, gruesome fiends and horrific ghouls seem to have emerged from the shadows. Hundreds are already dead, and most of them are still walking the streets. What will become of you, fair citizen? Will you become a meal... or will you fight back the hordes? Perhaps you'll even join their ranks.
Screams pierce the still air, accompanied occasionally by the sound of explosions in the distance. The lights have gone out, and morning has not been seen for days. You are now entering Serling city limits, where any day can be your last.
