Mutants & Machine-guns Rulebook

Publisher's blurb: Long, long time ago before the wars began, man was ruler of the earth. But one result of the terrible wars was that creatures rose from the ashes of the unknown. The genes of the earth's animals and plants were altered, until strange, new creatures arose - creatures of the awesome power and fierceness and often great intelligence. You have lived all your years among such creatures and among the strange artefacts - inexplicable, often dangerous- of the Ancients who created this now devastated civilization whose ruins you live among the world of Mutants & Machine-guns!
