Denver is a city in the pre-War American state of Colorado, mentioned in Fallout: New Vegas and its add-on Lonesome Road.


Said to have become overrun with feral dogs[1] following the nuclear apocalypse, the only known human inhabitants were the Hangdogs, a tribe who inhabited the outskirts of the city that learned how to live with the dogs, treating them as their spirit animals and companions in the post-War wasteland.[2]

Between 2277 and 2281, Caesar's Legion came to the city during their conquest of the tribes of the former American Southwest, led by Legate Lanius. The Hangdogs initially put up resistance, even managing to last longer than most others before them. However, the Legate put an end to their resistance by having legionnaires capture and burn the tribe's dogs alive on pyres, crippling their morale as they feared the dogs' spirits were doomed to burn forever in the afterlife. Soon after, the Hangdogs surrendered, were assimilated and their culture wiped out, apart from their skill in training dogs, with many being made Legion houndmasters.[3]

Despite ultimately succeeding, the cost of the takeover of Denver was steep, however; Lanius lost many men to a combination of factors, including supply lines stretched to the breaking point, vicious dogs that killed many, and the complete lack of a human population from which to draw new recruits to restore his army's numbers.[4] Even with the Legion's grip on it, the city still remains dominated by feral dog packs which may include pre-War police cyberdogs,[5][6][7] while they continue to procure its best dogs to add to their forces.[1]


In December of 1930, plans for the Hoover Dam were drafted by members of the Department of the Interior's Bureau of Reclamation within the city.[8][9]


Denver is mentioned in Fallout: New Vegas and its add-on Lonesome Road.

Behind the scenes[]

Denver is a real-world city of the same name, located in the state of Colorado.



  1. 1.0 1.1 The Courier: "Where does the Legion get its dogs?"
    Antony: "We breed them, mostly, but sometimes we get some good ones from Denver. That whole city is overrun with them."
    (Antony's dialogue)
  2. The Courier: "Tell me about yourself."
    Antony: "I've been around dogs all my life. They're my life, always were - all the way back when I was a tribal, one of the Hangdogs, outside Denver. Dogs roamed that city. Our tribe made peace with them. Thought they were our spirit animals - helped us hunt, provided for us in some lean times. Then the Legion came. Good thing, too. Stronger now, don't need those beliefs anymore."
    (Antony's dialogue)
  3. The Courier: "How did you end up joining the Legion?"
    Antony: "When the Legion showed up, we fought, most tribes did. Hangdogs hung out longer than most... broke us by throwing our dogs on the fire. So we gave up, our elders couldn't bear the idea of our spirit animals burning in the afterlife. Still, Caesar was impressed enough to conscript us, use our skills with dogs to join the Legion as houndmasters."
    (Antony's dialogue)
  4. The Courier: "As Legate, do you really believe that or are you taking a chance?"
    Lanius: "Hnh. Long ago... when taking Denver, I had to face such a challenge. Many died, over many years to claim the city as ours. It was the lines of food and water that nearly broke the Legion's strength... and the lack of tribals near that cursed city. What I felt in that struggle, I felt as I saw the map of the West. The West is a trap. The bear has already been caught in it, and it is dying."
    (Lanius' dialogue)
  5. The Courier: "I could use Lupa's brain to fix my cyber-dog."
    Antony: "Cyber-dog? Like the ones I've seen up in Denver? I know what you're talking about, and it would make Lupa immortal in a way."
    (Antony's dialogue)
  6. Antony: "The mechanical dog you have with you - where did you get it?"
    The Courier: "Rex? I picked him up in New Vegas."
    Antony: "Oh? Such things are common in Denver, but I didn't know that other cities had them as well."
    (Antony's dialogue)
  7. The Courier: "Why do you want to know?"
    Antony: "I ask because Caesar once had a similar pet, but it was lost during a battle."
    (Antony's dialogue)
