Burnout

Burnouts are former Humans mutated by toxic industrial waste on the planet Stygia.

Overview
Originally a Human colony, Stygia was home to a resort city residing thousands. However, in order to cut costs, the corporations responsible for the city utilised convicted criminals as a cheap workforce to build and maintain it. Eventually, the convicts rebelled and started sabotaging the city's infrastructure, including the environmental shields protecting the residents from Stygia's dangerous ecosystem. Desperate to escape the rampaging convicts, the people of Stygia fled to the underground, only to become trapped with the toxic byproduct of the city's systems and industry. While the convicts reorganised into a tribal horde known as the Skulls, the citizens of Stygia were mutated by the waste and became another horde of skinless, bloodthirsty mutants known as the Creeps. However, others mutated more dramatically and instead became the Burnouts.

Unlike the Creeps, who maintain enough of a semblance of humanity to utilise firearms and coordinate in what is effectively a gang war against the Skulls, the Burnouts are entirely feral. Resembling blackened humanoids with skull-like faces and orange blood, Burnouts are highly resistant to gunfire and can withstand a considerable volume of bullets with no significant harm. However, they also have a random assortment of orange cysts dotted around their bodies, which represent their weakness. Damage towards these cysts is enough to utterly destroy the Burnout, ripping it apart and dissolving whatever remains.

There exists a sub-species of Burnout referred to as Muta-Burnouts. These are much larger and strogner than Standard Burnouts and lack the weakness of cysts to exploit. Only three have been documented and were killed by circumstantial means, particularly by a helicoper roter, a vat of toxic waste and exposed electrified machinery.
