                              created. The global Gazos-Murlison Co empire fell in a nuclear \
                              attack, and most cities of the world were destroyed. \
                              A few cities around Australia, like this one, took some fallout \
                              but survived. The few remaining cities are now all independently \
                              run. I was a young governor under the empire, and I now rule inner \
                              Melbs as the King. I have gotten all the fallout out from the inner city, \
                              and I have a robot police force to keep you safe from the worst baddies, \
                              but be warned - there still are some dangers near by, and the world \
