Isaac Clarke finds himself in a strange new world, where humans don't exist and pastel-colored ponies can talk. He's taken home by one of them, Twilight Sparkle, for study. However, Isaac learns of a new Marker outbreak. Can he and the studious mare brave the trials of the new Marker and stop the spread, or will they succumb to the fierce Necromorphs and the harsh Unitologists?
