The Floating City

From publisher blurb: The Floating City is an adventure for the Apocalypse Essentials post-apocalyptic RPG, taking PCs from Atlantik City to the edge of the ruins of New York searching for wonders of the Ancients. Includes sea encounters, creatures, maps and ruin diagrams, NPCs, and hints at integrating character backgrounds. While ideally designed for the Apocalypse Essentials system it may be used with other post-apocalyptic RPGs with some conversion or substitution of creature statistics.
