uhhh not quite
What's revealed in the first episode: Humans are doing some sort of operation on this planet, they brought along their worker robots to do- uh- work. The humans, being stupid, blew part of the planet up, so now there's no more organic life. The worker drones survived and started a mini-civilization. The parent company that made the drones didn't like that, so they sent the terminators to kill the worker drones.
At least, that's what it seems like... Each episode reveals a new twist and uncovers new truths about what happened.
