Helldivers 2

The stories also showed that theaws were probably as good as could be done, since the exceptions were edge cases that required some creative interpretations of "protect" and "don't harm".

The stories where the laws were given exlusions so the robots could do things also reinforced the idea that the laws were pretty darn good even if they weren't foolproof. I think there was one with mining robots that had some flexibility on protecting themselves because mining is dangerous.

There is mega fucked evidence for it that the helldivers run into on a regular basis, the dozens of colonist corpses herded into the automaton bases and butchered on slabs for their brains.

They are also speaking very distorted english, including rarely thanking the player for killing them (perhaps varies with localisation), and use the exact same color and flag as the cyborgs did during the first war. And those certainly were humans, albeit definitely on the affront to nature side.

And lastly the cryptic message that was once posted on IRL social media, which decodes into a message that the automatons are the children of the cyborgs.

So my personal theory is that we learn over the course of the story that the automatons are some sort of nightmarish last ditch effort the cyborgs made; creating self replicating adaptive war machines running on human brains.
