Mutant Apocalypse

Long after the world ended, the survivors crawled out into the light to find that humans were no longer the dominant species.
Whether it was from radiation, genetic mutation or something only imagined in nightmares, new creatures now walked the planet, most seeking human flesh or perhaps wanting to make mankind bow to their will.
Mutants of all kinds were everywhere: some covered with scales, others dripping slime, or an amalgamation of multiple species, such as one with the head of a goat, gills instead of lungs, and six limbs instead of two.
At the end of the world, there will not only be death and destruction, there will be an apocalypse like none would have ever dared dream.
A mutant apocalypse!
When the end comes, that is when mankind's suffering will truly begin.
