ULTRAKILL(final war)

Within a few centuries, the industrial civilization of the Western Old World rapidly expanded across the globe. The newly established industrial societies reached their zenith within a mere thousand years of inception, what follows is the Final War, a bloody, prolonged conflict of endless bloodshed spanning over two centuries. Being the very last war that mankind engaged in against others, it had nearly brought humanity to its end, and reached heights of violence and savagery outshining all wars in history.

The Final War began with human-on-human trench warfare fought with bullet guns, which would go on to be out-economized by Electric and Heat weapons. This phase didn’t last long, as human combatants would come to face swift and efficient eradication by the newly-developed Guttermen; one of the first successful experiments in using Blood as a fuel source, as well as the first automatons to be deployed in wide-scale conflict. They also serve as a prime example of the savagery of the war itself; researchers hadn’t yet found a way to keep the blood fresh within the machine itself, and so would seal live humans (often unwillingly) into the metal caskets on their backs to drip-feed their fuel.

It is known that most machines, as well as most of the weapons, were created for the Final War. Electric guns and Heat weapons rendered bullet guns irrelevant due to machine-to-machine combat.

The Guttermen paved the way for the next phase of the war, a blood-machine arms race between the various armies, each new iteration made to counter the previous, beginning with the Guttertanks and spiraling out of control from there. With human combatants so thoroughly outclassed and blood fuel technology improved, human combat was phased out entirely, yet the war stretched resources thin and safety thinner for the survivors.

The final and most devastating phase of the war began and ended with the 1000-THR “Earthmovers”, weapons of mass destruction, machines of such size and power that it took only one to level an entire city, large enough to come equipped with a shield generator that rendered them impervious to outside attacks. However, they could be destroyed from within, and thus, they became the new frontlines for smaller infantry machines and possibly even V1 itself.

V1 was created towards the end of the Final War likely around the year 2112. However, only one prototype was produced, and the war ended before large-scale production began. The end of the war killed demand for V1, and the subsequent V2 program repurposed for peace was also a flop.

At some point, the Final War escalated to the point where most of the Earth was rendered uninhabitable, the most likely culprit being the Earthmovers. The few survivors were forced to settle upon the Earthmovers, until the resulting soot and debris blocked out the sun, and the Earthmovers, relying on solar power to function, died out one by one. As warfare was entirely reliant on them
