Champion of Earth: Robots and Cyborgs Expansion (2017)

["We'd always planned to extend the enemies that were attacking Earth alongside the aliens. Robots and Cyborgs are the first to join, putting their steel bodies and mechanical minds to the task of defeating the last defenders of Earth. The Alien invaders have promised the Robots a "chunk of Earth" in return for helping them defeat Humanity... Little do the repressed mechanicals know that they will be getting the Earth's core! They have agreed and joined the Aliens in their invasion, giving Humanity another enemy to stand against. Includes one (1) new double-sided character card, seventeen (17) new equipment cards and eighteen (18) robot and cyborgs cards. "]
