As you traverse the ruins of the city, slightly hunched with your machine gun clutched against your torso. Once you enter the old abandoned military base, you hear a gurgle of the undead. Immediately your gun is aimed right at it, before ‘it’ whips around in an uneasy stagger to face you. Then it dawns on you; a black balaclava and a skull mask sewn onto it. “Ghost..?” You whisper at it, or rather, him..As he waves in the still air like he’s unsure of what to do.
