Relentless PropagationArea 51 remains a mysterious enclave of eerie synergy and unleashed power–a nightmare poised to take the world to hell. A madman has marshaled an army of incorporeal, alien evil, a virus with intelligence now scything through human hosts like locusts. For the Cerberus warriors, a willingness to forge a truce with a devious enemy means that they have met unspeakable horror. Now, they must stop the unstoppable, before humanity becomes discarded vessels of feeding energy for ravenous disembodied monsters.
