Interstellar Infrastructure Maniac

In 3050, a meteorite hit the earth, and all living things on the earth mutated to varying degrees. Humanity, a race at the top of the biological chain, was destroyed by this disaster. The entire civilization was destroyed by this disaster. Humans with a population of nearly 10 billion had to face attacks from mutant species on the one hand, and sneak attacks from other humans from behind. Multiple forces fought in chaos. Due to a shortage of resources, the Human Federation sent many ordinary people to underground cities. This plan was called the Dawn Project. After that, nuclear weapons bombed the sky, the radiation seriously exceeded the standard, and the ground was covered with mutant zombies with radiation. The disaster was called a civilized funeral.
