Monoliths of Rust (2012)

Publisher blurb:

"Monoliths of Rust" is the first expansion book for the post-apocalyptic game world of Dystopia Rising. This sourcebook provides a look at what has become of New York and Massachusetts after the fall and at the denizens that inhabit these ruined landscapes. Explore the flooded marshes of the Mass and the creaking metal skeletons of Old York alongside the rival Baywalkers and Yorkers that call these regions home. Delve into the religion known as the Sainthood of the Ashes and learn of their philosophies, cults, and temples across the wastes.

This book also includes advanced mechanics for aquatic combat, a new character race and backgrounds, and an armory of iconic equipment to add flavor to the fallen future.
