H1Z1? I know that we feared being bitten, so I think it was the usual zombie bite infection. But how that relates to the aliens, I have no idea. I never saw the aliens, just their walking ships. I think the ships had 6 legs (more than the stereotypical tripod 3, at least), but the legs had nodes/segments that made them look more like spines, and they glowed.

edit: Wait, now I'm remembering another less-well-developed piece. The children. There was at least one infected child who became a kind of speaker for the aliens, issuing verbal commands that the adult zombies couldn't speak. I remember it standing in the door to a hallway saying something. I don't remember what it said. Something kind of like Torchwood's third season, maybe? I don't know. That's the only flash of image I have of that plot point of my dream. They were carriers to be feared (agents of the aliens, apparently?), but they were not like the flesh-eating monsters.
