"Ambulans mortuus: noun. Lit. "moving dead" (lat.). A viral strain that appeared in the Western Hemisphere in the early 21st century. Origin unknown. Characterized by high fever and death in infected subjects, followed by reanimation and extremely violent behavior. No known cure." -Merriam-Webster Dictionary. 2021 Edition. New Mexico, the domain of the Rattlesnakes, and the Whiskey Delta. For years, the undead have been roaming the countryside, feeding on the living and spreading their disease. But within a small compound outside of Espanola, the men and women of the 200th Infantry Brigade are fighting to take back the country. Under the command of Major General Thur, the "Mage", they are dedicated to stopping the spread of the virus any way they can. However, things quickly escalate when the Mage discovers an opportunity to end the war sooner than expected. All that's needed is a desperate mission into the ruins of Los Angeles - ground zero in the war against the Whiskeys and a land heavily contested by human foes - to find the first man infected by the undead strain. What could possibly go wrong?
