Hell has been unleashed upon Earth. At the start of the invasion the four horsemen led the charge and decimated the population, but something has changed. They seek retribution for their wrongs, but they shall only find it if they find a human dubbed "the vessel." To accomplish this they will return where they invaded, Las Vegas, but they weren't the only creatures to crossover. Can the Angels of Hell survive a battle against Lord Asmodeus and his lustful succubi to save humanity's soul?
