The machines are introduced in chapter 9 where Cap'n Ezma and Ethan come back to your colony. So you shall turn them into your servents and use them to destroy the Mutants which they too fight in their quest to... what is their quest? To rid the world of everything that is a threat to them? Please Note that there are friendly robots too, Like Abe... Yes he is a robot... no he's not trying to kill you. Notable Robot factions include the MCP, and the TEC.
