Skeleton

You hear faint footsteps, so you follow the sound through the maze. To your horror, you discover the source of the footsteps is a Skeleton; and it doesn't look friendly. Acting quickly, you blast it with your Undead Disintegrator and the Skeleton vanishes in a flash of colour. But as you reload your UD, you hear footsteps again; and you wonder; are you the hunter or the hunted in this nightmare?
