From the back of the book:
Your friends are dead, your family is missing and the only thing standing between you and the angry mob; is a body that can lift a ton, run at 100mph and fire bolts of living flame. Welcome to the world after the end of the world. Don't be afraid...
Nemesis; A Perfect World answers the age old question, "What would you do with superpowers?". Players create characters based on themselves. Blessed or cursed with fantastic powers and abilities, living in a realistic world full of deception; this time the fate of the world dosen't[sic] depend on strange visitors from other worlds, mutants, or dark detectives...it depends on you.
