From publisher blurb:
SURVIVE AND THRIVE IN A POST-APOCALYPTIC WORLD OF MUTANTS, ANDROIDS, CYBORGS, ROBOTS, AND HIGH TECHNOLOGY!
Delta World is a wild and sparsely populated future Earth. It is 150 years after The Great Catastrophe, an apocalyptic global war that resulted in the complete destruction of civilized society. The environmental contamination from chemical, biological and radiological warfare has resulted in a world of mutated beings: animals, humanoids, plants, and others.
Now, finally, the small communities of intelligent beings that have survived are beginning to claw their way back from the depths of technological ignorance. Their numbers are expanding, and they strive to create new civilizations once again. You are one of these intelligent beings. You live in a world that has been reclaimed by nature, where overgrown ruins can be exploited for the vast technology once mastered by the Ancient Ones. With luck, you and your companions can find these ancient ruins and scavenge the materials, equipment, and technology that you need to continue to advance. But the world is dangerous, unexplored, and treacherous. Can you survive?
Compatible with the Fifth Edition System Reference Document and Open Game License system rules for the world’s oldest roleplaying game, Delta World creates a post-apocalyptic, science fantasy expansion with a crisp gameplay experience and an old-school RPG feel.
