HZD is a grey goo scenario with extra steps. Not only what we are missing is self replication but everything else including the important part and what was the problem “converting bio-mass into energy” without that it wouldn’t be an issue, not to mention that HZD makes little sense in general even with the coverup nukes exist and they blow up shit just fine their lore made little sense in the long run as they couldn’t replicate they just had really big robots the octopus ones that could manufacture more of the smaller ones. And more importantly since the biomass conversion was basically nano machines why couldn’t you produce a swarm of them that simply eats robots? Or why couldn’t you produce a swarm of robots to fight the rogue swarm. The whole “unhackable” thing also doesn’t makes sense and if they were then well make another swarm that just is unhackable and let them duke it out. The technology and more importantly the consistency of the technology in that universe makes absolutely no sense. As much as I liked the game the story while cool was about as plausible as an alien invasion that triggers a zombie apocalypse followed by the second coming.
