After an apocalyptic event, the entire human race has been turned into zombies by a nuclear reactor explosion, this has happened not only in USA but also in a global pandemic, but now only we can be the saviors of the human race. Linda, Victor and a robot guided by a built-in artificial intelligence that I decided to call OODDA, we live in a nuclear-proof underground bunker about 328 ft underground, we have enough food for about 30 years. If that many people remain.
