Enemies Galore: Dozens of villains, organizations, and teams to throw against your heroic Enforcers. City of Sin: Chicago in the 21st century is owned by the criminals. Inside you will find important characters, the rulers of the Windy City, and their minions. Cybenetics [sic]: Limbs, weapons, and deadly Combat Chassis. New Weapons, Powers, Magic and Psionics: Useful information for any Enforcers Campaign, from lethal blasters to such powers as Cold Weather Manipulations and Pleasure and Pain Projection. Plus a new archetype: the Jacker-technologist, master hacker and electronic courier of the Information Age. Designed for use for Cosmic Enforcers, but usable by any Super-heroic or Science Fiction RPG."
