Common weaponry is ineffective against the demons. Heroes don’t use M-16s or AK-47s to fight the forces of Hell, but instead use exotic super-science weapons like the Arc Lasher or the HARP rifle. As opposed to bullets, projectile weapons fire sharpened spikes made from Palladium that have been ionized with holy water. Even more mundane weapons such as Flame Throwers use alchemical solutions – such as the long forgotten Greek Fire – as opposed to simple napalm. Energy weapons use the works of Tesla as a basis from which to generate electrical charges, unleash streams of intensified light.
