There is a loud crack and a flash of blue light as Ricardo strikes out with his stun-baton, sending a powerful jolt of electricity through one of the onrushing ghouls. It drops to the dirty concrete floor of the tunnel, gasping for breath as one of its companions, a huge ghoul covered in bony lumps of armor, leaps in and stabs Ricardo with a long spear of bent metal. The stun baton flashes with a crack and the scent of ozone. The ghoul howls in anger, twisting on the metal spear. Ricardo screams in agony and drops to the ground, red blood pumping from his chest.
