Forsaken

In the distant future, the advancement of science has exceeded humanity's ability to control it. During a subatomic experiment, an accident causes an uncontrollable fusion reaction, utterly destroying the surface of the planet Earth.
One year later, Earth has been classified as "condemned" by the ruling imperial theocracy, meaning that it is now legal for anyone to salvage anything left on the planet. Mercenaries from all over come to raid the dead planet, forced to battle not only each other, but the robot sentinels that the government has left behind.
