From getting some tiktoks of Helldivers 1 lore, the Cyborgs are the precursor to the Automatons and have basically been entombed on Cyberstan (lmao), which is where they sought to be a free, independent socialist society of augmented humans and any others rejecting the fascism of Super Earth.

Helldivers 2 is apparently 100 years after, and there's suspicions that the Automatons aren't just a collective of killing machines making a beeline towards Super Earth - the forcibly-augmented/fully robotic have some level of sentience and are apparently mounting a liberation campaign on Cyberstan by travelling around the periphery.

also apparently the bugs literally produce oil and were bred for this purpose lmao
