Amaroxia was a planet of subterranean peoples, forced underground by the death of their sun. The Amaroxian civilization began to suffer from an energy shortage and sought to hastily resolve it by developing a new energy source. Unfortunately, when processed, the source of energy produced a volatile gas that is toxic to lifeforms on Amaroxia, which began to mutate residents of the underground society.

Machines were developed to assist in life underground. These machines were a new type of exoskeleton, designed to be more form fitting and engaging than the clunky exoskeletons used for digging. These smaller, faster suits were dubbed Turbo Suits. They placed the hope of their future on these new machines.

The Mugenes disease continued to consume everything in its path, rapidly twisting the denizens of the underground realm.
