Mexico City

 was the capital of Mexico. In 2042, a major earthquake hit the city, destroying almost he entire city. Use of Mr. Handy robots in the reconstruction made them one of the most popular robots of the 21st century.

All of this was for naught, as in 2077, the city was destroyed by nuclear bombs, turning it into a radioactive ruin. Many citizens were forced to flee to surrounding settlements and farmlands. Not long after the war, scavengers and raiders started to infest the city and criminal activities became bigger than what they were before the war.
