The Cyborg Legion are an Automaton sub-faction and a returning enemy from Helldivers 1, introduced in the Machinery of Oppression update. They were first encountered on their homeworld of Cyberstan during the course of Operation Valid Pretext. Cyborg Legion were former  Super Earth citizens who wanted to secede from the Federation. Having founded the  Cyborg Nation, their secession would land them in direct conflict with the Federation of Super Earth during the events of the First Galactic War Following their defeat at the end of the war, the Cyborgs were enslaved and forced into the mines of Cyberstan -their former capital- in order to mine resources close to the planet's core. Due to the high temperatures close to the core, the Cyborgs (further[1]) augmented their bodies in order to survive the harsh environment. During their servitude, the Cyborgs were given mining robots from Super Earth to help with mining resources faster; robots which would later be used to create the first prototypes for the  Automatons, before being shipped outside Federation space inside a stolen vessel: Vessel 00. When the Automaton forces built up into a sizable invasion force they returned to Cyberstan to free the Cyborgs from Super Earth's control.[2] Now, the Cyborgs mass produce new units by synthesizing flesh at unnatural units in their Cyborg Production Units in Megafactories, explaining how Cyborgs in the 2nd Galactic War differ in form from the Cyborgs in the 1st Galactic War.
