Man & Machine

The Washington encounters a Class-M world that is similar to Earth with a large radioactive signature. Upon scanning the planet from orbit, they determine that the planet is suffering from nuclear winter, the result of a nuclear war. Perhaps more intriguing, they detect human life signs. When they are unable to contact anyone on the surface, they attempt to shuttle down to a large human concentration only to be fired upon by cybernetic creatures who are at war with the humans.
